Unfortunately, this functionality in large part based on a struct
member that was made private in FFmpeg/FFmpeg@7489f63281
in May. Unfortunately, this was not noticed during review.
This reverts commit 0862664ac9.
This exposes whether a video track is detected as an image. This is
useful for profile conditions, property expansion and lavfi-complex, and
is more accurate than any detection even Lua scripts can perform, since
they can't differentiate between images and videos without container-fps
and audio and with duration 1 (which is the duration set by the mf
demuxer with the default --mf-fps=1).
The lavf demuxer image check is moved to where the number of frames is
available for comparison, and is modified to check the number of frames
and duration instead of the video codec. This doesn't misdetect videos
in a codec commonly used for images (e.g. mjpeg) as images, and can
detect images in a codec commonly used for videos (e.g. 1-frame gifs).
pix files are also now detected as images, while before they weren't
since the condition was checking if the AVInputFormat name ends with
_pipe, and alias_pix doesn't.
Both nb_frames and codec_info_nb_frames are checked because nb_frames is
0 for some video codecs (hevc, av1, vc1, mpeg1video, vp9 if forcing
--demuxer=lavf), and codec_info_nb_frames is 1 for others (mpeg, mpeg4,
wmv3).
The duration is checked as well because for some uncommon codecs and
containers found in FFMpeg's FATE suite, libavformat returns nb_frames =
0 and codec_info_nb_frames = 1. For some of them it even returns
duration = 0, so they are blacklisted in order to never be considered
images.
The extra codecs that would have to be blacklisted without checking the
duration are AV_CODEC_ID_4XM, AV_CODEC_ID_BINKVIDEO,
AV_CODEC_ID_DSICINVIDEO, AV_CODEC_ID_ESCAPE130, AV_CODEC_ID_MMVIDEO,
AV_CODEC_ID_NUV, AV_CODEC_ID_RL2, AV_CODEC_ID_SMACKVIDEO and
AV_CODEC_ID_XAN_WC3, while the containers are film-cpk, ivf and ogg.
The lower limit for duration is 10 because that's the duration of
1-frame gifs.
Streams with codec_info_nb_frames 0 are not considered images because
vp9 and av1 have nb_frames = 0 and codec_info_nb_frames = 0, and we
can't rely on just the duration to detect them because they could be
livestreams without an initial duration, and actually even if we could
for these codecs libavformat returns huge negative durations like
-9223372036854775808.
Some more images in the FATE suite that are really frames cut from a
video in an uncommon codec and container, like cine/bayer_gbrg8.cine,
could be detected by allowing codec_info_nb_frames = 0, but then any
present and future video codec with nb_frames = 0 and
codec_info_nb_frames = 0 would need to be added to the blacklist. Some
even have duration > 10, so to detect these images the duration check
would have to be removed, and all the previously mentioned extra codecs
and containers would have to be added added to the blacklists, which
means that images that use them (if they exist anywhere) will never be
detected. These FATE images aren't detected as such by mediainfo either
anyway, nor can a Lua script reliably detect them as images since they
have container-fps and duration > 0 and != 1, and you probably will
never see files like them anywhere else.
For attached pictures the lavf demuxer always set image to true, which
is necessary because they have duration > 10. There is a minor change in
behavior for which audio with attached pictures now has mf-fps as
container-fps instead of unavailable, but this makes it consistent with
external cover art, which was already being assigned mf-fps.
When the lavf demuxer fails, the mf one guesses if the file is an image
by its extension, so sh->image is set to true when the mf demuxer
succeds and there's only one file.
Even if you add a video's file type to --mf-type and open it with the mf
protocol, only the first frame is used, so setting image to true is
still accurate.
When converting an image to the extensions listed in demux/demux_mf.c,
tga and pam files are currently the only ones detected by the mf demuxer
rather than lavf. Actually they are detected with the image2 format, but
it is blacklisted; see d0fee0ac33.
The mkv demuxer just sets image to true for any attached picture.
The timeline demuxer just copies the value of image from source to
destination. This sets image to true for attached pictures, standalone
images and images added with !new_stream in EDL playlists, but it is
imperfect since you could concatenate multiple images in an EDL playlist
(which should be done with the mf demuxer anyway). This is good enough
anyway since the comment of the modified function already says it is
"Imperfect and arbitrary".
Because youtube-dl is inactive and the yt-dlp fork is becoming more
popular, make mpv use yt-dlp without any extra configuration.
yt-dlp is ordered before youtube-dl because it's more obscure, so users
who have yt-dlp installed are more likely to want to use it rather than
youtube-dl.
Fixes#9208.
The "cycle" command _declaration_ enables repeatability by default,
however, the command handler applies additional logic to augment it,
based on the property which is being cycled - using some guesswork.
Specifically, properties with discrete values are not repeatable
(like sub or osd-level), while continuous properties are repeatable
(like volume).
Previously, the "repeatable" prefix could not override this additional
logic.
This commit changes the behavior so that the logic affects only the
default repeatability (still based on the property like before),
however, the "repeatable" prefix is now allowed to override it.
Previously, a list of commands was always considered repeatable.
This behavior was added at 6710527a (and moved around since then),
in order to fix#807 (impossible to make a repeatable list).
The problem was that a list doesn't have the normal repeatability
flags and so it was never repeatable, so it was hardcoded to be
repeatable instead. Presumably it was deemed good enough.
However, this made it impossible to have a non-repeatable list.
This commit changes the behavior so that a list repeatability is
that of the first command at the list.
This way, any list can be made either repeatable or non-repeatable
using the following idiom (e.g. at input.conf), based on the fact
that the "ignore" command is not repeatable by default:
x ignore; cmd1...; cmd2... # non-repeatable
y repeatable ignore; cmd1...; cmd2... # repeatable
Fixes#7841

- Replace the legacy --osd-status-msg with the newer --osd-msg3.
- Escape \b in show-text "This is ${osd-ass-cc/0}{\b1}bold text".
- Link the Flat command syntax section because it's no longer true that
you always need to escape \, since C escape sequences are not
interpreted with single and custom quotes.
The previous wording gave the false impression that there was no media
key support for OSes besides Windows and macOS. This is untrue, the
option may only exist on those two platforms but it simply means that
media keys will always be enabled on other OSes as long as they are
supported.
There's currently some touch related code in mpv wayland, but clearly
nobody actually uses because it's a broken mess. Initially an attempt to
distinguish between two finger touches and one finger touch was made,
but there's not a good way to make this work. For whatever reason,
initiating either xdg_toplevel_resize or xdg_toplevel_move blocks any
other touch events from occurring (at least in plasma). Trying to call
these functions anywhere else is not really useful since the serial will
be invalid outside of the touch down events (well it would work in the
touch up event but that's just silly).
Anyways, let's just make this work sanely. Eliminate the touch entries
variable completely because it's pointless. Only one finger event is
ever considered at a time. Touches besides the initial one are all
ignored. If a user touches and drags within the touch edge radius, then
a resize event occurs. If the user touches and drags elsewhere on the
window, a move event occurs. A single tap displays the osc (which is
clickable if you tap again). A double tap toggles fullscreen.
Additionally, the default touch edge radius of 64 pixels is way too big
(at least I think so). Cut this in half to 32 which feels a lot better
(on a pinephone using plasma mobile anyway).
The window-scale property mirrors the respective option (not the
effective scale derived from the current window size), and as such
setting its value to the same value it had before has no effect.
Specifically - the window will not resize.
This is consistent as far as property-option bridge behavior goes,
but we do end up with an issue that we can't set an arbitrary scale
and expect the window to always resize accordingly.
We do also have a current-window-scale property which does reflect
the actual window size, however, it's been read-only till now.
This commit makes current-window-scale RW so that it's now always
possible to set an arbitrary scale and expect the window to resize
accordingly (without affecting window-scale - like manual resize).
Also, mention window-scale no-effect-if-not-changed at the docs.
Based on code by @Dudemanguy from commit 873ae0d, with same effect.
This reverts commit 873ae0de2a.
The next commit will restore this functionality, with the
following differences from the reverted commit:
- Smaller and simpler code change.
- On bad scale: use "Invalid value" (compared to "no such property").
- Doesn't combine the docs for window-scale and current-window-scale.
- Doesn't remove the docs for window-scale behavior prior to 0.31.0.
Somewhat confusingly, mpv has both a window-scale option and a
current-window-scale property. The documentation lists window-scale
under properties (and it is technically is one), but at its core it is
actually an option which means it behaves subtly different. Options in
mpv are runtime-configurable, but they only change anything if the value
of the option itself changes. window-scale is an option and not meant to
keep track of the actual scale of the window (intended behavior
introduced by d07b7f0). This causes window-scale to do nothing in
certain cases (ex: the window is manually resized and window-scale is
set to 1.00 again). This is logical and consistent with the behavior of
the rest of the mpv options, but it also makes it a poor candidate for
setting the mpv window scale dynamically.
As a remedy, we can just make current-window-scale writeable instead.
current-window-scale is intended to always report the actual scale of
the window and keep track of any window size changes made by the user.
By making this property also writeable, it allows the user to have more
intuitive behavior (i.e. setting current-window-scale to 1.00 always
sets the window to a scale of 1). Additionally, the default input.conf
is changed to use current-window-scale instead of window-scale. The
window-scale documentation under property list is removed since it is
already documented under options and users should probably set the
current-window-scale property instead in most cases.
Using --sub-filter-regex-plain (default:no)
The ass-to-plaintext functionality already existed at sd_ass.c, but
it's internal and uses a private buffer type, so a trivial utility
wrapper was added with standard char*/bstr interface.
The plaintext can be multi-line, and the multi-line regexp flag is now
always set, but only affects plaintext (the ASS source is one line).
Pretty much identical to filter-regex but with JS expressions and
requires only JS support. Shares the filter-regex-* control options.
The target audience is Windows users - where filter-regex doesn't
work due to missing APIs, but mujs builds cleanly on Windows, and JS
is usually enabled in 3rd party Windows mpv builds.
Lua could have been used with similar effort, however, the JS regex
syntax is more extensive and also much more similar to POSIX.
Users expect single quotes to work when the value includes literal
backslashes or double-quotes (or as general quoting like in shell).
The updated docs also include some previously-missing notes:
- newline is only supported in double quotes.
- adjacent (quoted) arguments don't join into one.
Supporting mixed quoting (adjacent quoted strings) would make
mpv's parsing more complete, but would require delicate effort of
larger scope, for two reasons:
- We'd need to also support escaping outside of quotes and do our
best about backward compatibility.
- The parsed value can either be a substring of the input or
a newly-allocated string, which would be delicate when joining.
Not critical to add right now.
Custom quotes were added in 4f129a3e and began with !, however, this
required quoting "!reverse" (used for the cycle-values command), which
is inconvenient, and was not taken into account when ! was chosen for
custom quotes. Also, ` is more natural for quoting than !.
This does break backward compatibility with the earlier form of custom
quotes, but at least we didn't make a release yet since custom quotes
were added (the last release - 0.33[.1] doesn't support it).
Let audio-display determine whether embedded images or external cover
art tracks should be selected when both are present.
Attached pictures are given priority by default as requested in #8539.
Also updates references to attached pictures in the log and manpage to
refer to cover art as well.
Closes#8539.
This fix the warnings shown below when compiling the manual for
any of its three common formats:
```
DOCS/man/mpv.rst:46: (ERROR/3) Unknown target name: "--input-test".
DOCS/man/stats.rst:183: (ERROR/3) Unknown target name: "--input-test".
```
In rst, double-backtick starts a code string only if it's followed by
a non-space char, otherwise it's taken literally, hence, `` x2.0``
was taken literally rather than code string.
--watch-later-options-remove doesn't accept multiple options, so split
the example.
Also suggest the more correct -clr to empty the list, and remove the
workaround to not print an error with --watch-later-options=
This allows configuring which options are saved by quit-watch-later.
Fixes#4126, #4641 and #5567.
Toggling a video or audio filter twice would treat the option as changed
because the backup value is NULL, and the current value of vf/af is a
list with one empty item, so obj_settings_list_equal had to be changed.
Unlike the page switching/scrolling keys which are bound at runtime
and therefore we need to know which (configured) keys to bind, the
main keys (i/I by default) are static and can be bound via input.conf.
And indeed, the builtin bindings at etc/input.conf have them already.
- The video filter to turn the video upside-down is vflip. There is no
filter called "flip" so using it just causes an error.
- Reword a sentence.
- Add exact and all to the values accepted by cover-art-auto. They were
implemented in 029ff1049b but not added to the accepted arguments.
While --input-test is useful, and so is page 4 of stats, until now
there was no way to simply print the list in a help-like fashion.
This commit adds such printout, invoked by the script opt
stats-bindlist=yes, which uses the existing page 4 code. This prints
the list on startup and quits immediately - like any help page.
It's awkward to invoke compared to other help pages, and it does
require the stats page to be enabled (it is by default), however
it is a script-generated output, and currently there's no other
method to print a help page generated by a script.
The printout itself is performed using lua's io.write. While reliable,
it's not the standard way for mpv to print to the terminal.
Other possible printout methods are mp.msg.info - which also prints
"[stats]" prefix on each line (ugly), or forcing term-osd and setting
an osd-message which mpv will then print at the terminal - however
that's printed to stderr, and could also be subject to timing concerns
since we quit right afterwards.
In the future we can consider changing/integrating the invocation so
that mpv itself could print a help page generated by a script, thus
solving both the awkward invocation and printout-method issues.
This is a scrollable page which also works nicely with the terminal
OSD. Typically there are more than 100 bound keys.
It groups the binding using fuzzy property/command/script name after
simple analysis of the command string, and then further sorts the
binding in each group according to the "complexity" of the key itself
(plain keys -> keys with modifiers, alphabetically, etc).
The alignment/grouping style is heavily inspired by @medhefgo's #8924
but otherwise it's an independent implementation.
The --secondary-sub-visibility options was previously undocumented in
the pull request that added it. This commit adds documentation for it
and clarifies its behavior.
Modifies the sub-seek and sub-step commands with a second <flags>
argument to specify whether to seek/step on the primary or secondary
subtitles. The flag is used to index into the current_track array in
cmd_sub_step_seek.
Adds secondary-sub-start and secondary-sub-end properties by setting
the current_track index in the m_property's priv variable which later
gets accessed in get_times. Also adds a test of the secondary subtitle
time properties in tests/subtimes.js bound to 'T'.
Not sure what I was on when I wrote this. wayland-app-id is supposed to
default to "mpv". Just set that in the vo_sub_opts and don't do this
weird m_config_cache_write_opt thing. Also make the doc entry nicer.
This fixes a long-standing apparent issue where mpv would display the last
frame with no subtitles at EOF. This is caused by sub rendering switching from
video timestamps to audio timestamps when the video ends, and audio streams
often running past the timestamp of the last video frame. However, authoring
tools (most notably Aegisub) don't tend to provide easy ways to add meaningful
subtitles after the end of the video, so this is rarely actually useful.
This makes cover-art-auto behave more like sub-auto and audio-file-auto:
- load cover art with a language, e.g. if playing foo.mp3, foo.en.jpg
will be loaded with lang=en
- load cover art containing the media filename with fuzzy and all, e.g.
'foo (large).jpg'
- make all/2 load all images in the directory, and make fuzzy/1 the
default
These are all uncommon use cases, but synchronizing the behavior of the
external file options simplifies the code.
Commit 6abb7e3 updates the markers when the chapters change, but it
doesn't update their relative position at the bar when the duration
changes.
This means that adding chapters to a live stream would result in
corresponding chapter markers which were static while the duration
changed and thus their positions became incorrect over time until the
OSC was reinitialized.
This is fixed by observing the duration property if chapters are present
and reinitializing the OSC when the duration changes.
The live_markers user option, which determines whether the duration
property is observed when there are chapters, has been added in order to
allow disabling this behaviour as calling request_init() frequently
might have some impact on low-end systems.
The impact of request_init() on render() was measured to increase from
1-1.5 ms to 2-3 ms on a 2010 MacBook Air, while the impact was neglible
on a 2016 Surface Book (increasing only to an average of 1.4 ms from
1.3 ms for n=1500 render cycles).
The live_markers option is enabled by default.
This is the Vulkan equivalent of the drm context for OpenGL, with
the big difference that it's implemented purely in terms of Vulkan
calls and doesn't actually require drm or kms.
The basic idea is to identify a display, mode, and plane on a device,
and then create a display backed surface for the swapchain. In theory,
past that point, everything is the same, and this is in fact the case
on Intel hardware. I can get a video playing on a vt.
On nvidia, naturally, things don't work that way. Instead, nvidia only
implemented the extension for scenarios where a VR application is
stealing a display from a running window system, and not for
standalone scenarios. With additional code, I've got this scenario to
work but that's a separate incremental change.
Other people have tested on AMD, and report roughly the same behaviour
as on Intel.
Note, that in this change, the VT will not be correctly restored after
qutting. The only way to restore the VT is to introduce some drm
specific code which I will illustrate in a separate change.
And also change the existing WM_KILLFOCUS handler to return 0 instead
of 'break' (which later calls DefWindowProcW), as MSDN says we should
do for WM_{KILL,SET}FOCUS.
It seems that the 'focused' property is now supported by all main VOs:
x11, macOS, wayland, Windows.
TCT/sixel/caca probably don't support it, and unknown with SDL.
Fixes#8868
Not only does this have semantics that make far more sense, it also has
a default that makes far more sense. (Equivalent to the old
`icc-contrast=inf`)
This removes the weird 1000:1 contrast default assumption which
especially broke perceptual profiles and also screws things up for
OLED/CRT/etc.
Should probably close some issues but I honestly can't be bothered to
figure out which of the thousands colorimetry-related issues are
affected.
Add new header which shows up as tags/metadata (associated with
--display-tags). The way this is added means it doesn't always work,
because root->meta (see code) can be NULL for some absurd reason. But it
works for the one case I intended to use it (ytdl_hook, see next
commit), though only in default configurations.
For some reason, this never existed before. Add VOCTRL_GET_DISPLAY_RES
and use it to obtain the current display's resolution from each
vo/windowing backend if applicable. Users can then access the current
display resolution as display-width and display-height as per the client
api. Note that macOS/cocoa was not attempted in this commit since the
author has no clue how to write swift.
This commit describes more accurately what currently gets disabled
by this option - specifically also keys from mp.add_key_binding.
It's not necessarily the best behavior because libmpv clients might
want to disable mpv's own builtin keybindings while still allowing
scripts to define keys which `input.conf' can override.
In the future we might exclude mp.add_key_binding from this option,
but for now at least document this option accurately.
Fixes#8809
The ctime member on Windows uses FILE_BASIC_INFO.ChangeTime, which is
pretty much the same as st_ctime on POSIX.
See https://devblogs.microsoft.com/oldnewthing/20100709-00/?p=13463 :
... The LastWriteTime covers writes to the file’s data stream
(which you accomplish via the WriteFile function). On the other
hand, the ChangeTime also includes changes to the file metadata,
such as changing its file attributes ...
Fixes#8801
Some subproperties in osd-dimensions were returned as doubles despite
actually being integers. Additionally, correct a highly misleading line
in the osd-width/osd-height documentation.
The accurate description of this option was:
- fit-border is enabled by default. When disabled, it adds a bug where
if the window has borders and mpv shrinks it to fit the desktop, then
the calculation ignores the borders and adds incorrect video crop.
The option was added at commits 70f64f3c and 949247d6, in order to
solve an issue (#2935) where if mpv wanted to display a video with
size WxH, then w32_common.c incorrectly set the window to WxH, while
down-scaling the video slightly to fit (even with small sizes).
It was addressed with a new option which is enabled by default, but
does the right thing (sets the client area to WxH) only when disabled,
so that everyone who prefers their video slightly downscaled could
keep their default behavior.
(#2935 also addressed an off-by-one issue, fixed before fit-border)
While disabling the option did avoid unnecessary downscaling, it also
added a bug when disabled: the borders are no longer taken into
account when the size is too big for the desktop. Most users don't
notice and are unaffected as it's enabled by default.
Shortly later (981048e0) the core issue is fixed, and now the client
area is correctly set to WxH instead of the window (and together with
the three following commits which center the video, adds a new bug
where the window title can be outside the display - addressed next).
However, fit-border remained, now without any effect, except that it
still has the same bug when disabled and the window is too big.
Later code changes and refactoring preserved this issue with great
attention to details, and it remained in identical form until now.
Simply rip out fit-border.
When mpv attempts to play a video that is, on average, 60 FPS on a
display that is not exactly 60.00 Hz, two options try to fight each
other: `video-sync-max-video-change` and `interpolation-threshold`.
Normally, container FPS in something such as an .mp4 or a .mkv is
precise enough such that the video can be retimed exactly to the display
Hz and interpolation is not activated.
In the case of something like certain live streaming videos or other scenario
where container FPS is not known, the default option of 0.0001 for
`interpolation-threshold` is extremely low, and while
`video-sync-max-video-change` retimes the video to what it approximately
knows as the "real" FPS, this may or may not be outside of
`interpolation-threshold`'s logic at any given time, which causes
interpolation to be frequently flipped on and off giving an appearance
of stuttering or repeated frames that is oftern quite jarring and makes
a video unwatchable.
This commit changes the default of `interpolation-threshold` to 0.01,
which is the same value as `video-sync-max-video-change`, and guarantees
that if the user accepts a video being retimed to match the display,
they do not additionally have to worry about a much more
precise interpolation threshold randomly flipping on or off. No internal
logic is changed so setting `interpolation-threshold` to -1 will still
disable this logic entirely and always enable interpolation.
The documentation has been updated to reflect this change and give
context to the user for which scenarios they might want to disable
`interpolation-threshold` logic or change it to a smaller value.
Changes:
- code refactored;
- mixer options removed;
- new mpv sound API used;
- add sound devices detect (mpv --audio-device=help will show all available devices);
- only OSSv4 supported now;
Tested on FreeBSD 12.2 amd64.
Apple has decided that Mac OS X is now named macOS for the time
being. For consistency, it makes sense to use the same name for the
operating system in all places where it occurs. This commit renames
OS X to macOS in the documentation in places where it was otherwise
still using the old name.
Where X is any ASCII char chosen by the user. An argument is only
interpreted as custom-quoted if it starts with '!' and the line doesn't
end right after it. Custom quotes don't interpret backslash-escape.
This change only affects command arguments which mpv parses (not array
commands), and not tokens before the arguments (where applicable - key
name, input section, command prefixes, command name).
currently we use the whole screen rectangle to calculate the window
geometry. this doesn't take the menu bar or the Dock into account.
by default use the visible screen rectangle instead. this is also a
change in behaviour, since the window can't be placed outside of this
rectangle anymore. also add an option to change to the old behaviour,
because it can still be useful in certain cases, like placing the window
directly underneath the menu bar when used a desktop background.
Fixes#8272
--alpha=yes doesn't affect only transparent videos and images, but also
the background. I spent time researching how to implement transparent
backgrounds and had no idea that they already worked at least on
Wayland.
Background transparency will work on X11 when
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/2376 is
merged. It doesn't work on Windows. No idea about macOS. Either way,
this paragraph already says that it only works on certain environments
twice.

With the current wording, I thought that playlist-prefetch doesn't
prefetch the next url within a playlist of m3u8 urls, but it makes a big
difference, and I would have enabled it earlier if it wasn't for this
paragraph.
This makes it clear that you can prefetch any file, but that it won't
prefill the cache with the video data. This is true for any video,
there's nothing unique about HLS streams in the behavior of this option.
Simple groundwork for adding a couple of user options that allow
selecting the screen with a string name. The next two commits implements
these options for xorg and wayland.
While this says that _ is replaced with -, it doesn't say that you HAVE
to use _. This isn't obvious and I didn't understand why my profile
conditions with - weren't working at first. Seeing as the person who
reproted #8324 ran into this as well, this may be worth clarifying.
For two reasons:
1. It was counter intuitive that there's an "auto" value (which is
actually a libsixel value and not an mpv one), but it's not the
default value - our default was Atkinson.
2. "auto" provides better dithering than Atkinson with libsixel, which
is especially noticeable with smooth gradients - where Atkinson has
visible banding.
In libsixel 1.8.2 the "auto" value maps to Atkinson if the output
palette has up to 16 colors, or to Floyd-Steinberg otherwise (e.g.
using fixed palette with 256 colors chooses Floyd-Steinberg).
The issue was that we only uploaded the palette to the terminal when it
changed (once on init with fixed palette, every frame with dynamic
palette with trheshold=-1, only on scene change with threshold >= 0).
Now we upload it on every frame, and it seems to fix the mlterm image
corruption both with fixed palette and also with dynamic palette with
threshold (i.e. at frames which did not upload a palette).
It's not entirely clear why it's required with mlterm.
It would seem that the palette which libsixel uses with fixed palette
matches the built in default palette in xterm, but not in mlterm.
With dynamic palette we can guess that mlterm resets the palette after a
sixel image, but that's not confirmed.
Uploading the palette on every frame doesn't seem to slow down xterm
when using fixed palette - not clear yet why uploading a different
palette (when using fixedpalette=no) slows it down while same palette
on every frame doesn't.
In mlterm there's no slowdown either way - and now also no corruption.
By default we still clear the screen, but now it's possible to leave the
last sixel image on screen.
Allows mpv to be used as img2sixel of sorts, but with our auto-fit and
various mpv scaling/filters etc.
This reverts commit 3d17e19c2c.
The effect of turning off this setting is that mpv doesn't tell libass what
the video stream's resolution is. This happens to result in some files having
their transforms scaled in ways that give higher performance (as described
in #7435) because libass happened to guess a video resolution that resulted
in transforms yielding smaller bitmaps, but it's just as easy for the opposite
to happen depending on the resolutions and effects involved.
The option's name is also somewhat misleading: setting the storage size affects
blur, but it also affects stroke (which is far more important for the vast
majority of scripts) and 3D transforms (which look very screwy when done wrong).
Resize the image based on the dimensions reported by
vo_get_src_dst_rects to correctly handle aspect ratio
that might be set/ignored.
Added pad-x and pad-y options for padding.
These options will be used to remove the extra padding.
Some terminals report the padding of 2px in the ioctl
dimensions which can't be used for displaying sixel
output. These options can be used for fine tuning
the output video resolution.
Now all the terminal size detection and calculation logic
is done in a single function at resize. Also top and left
values are computed from the dst_rect parameters to simplify
the logic for the aspect ratio based centering.
Additionally vo-sixel-rows and vo-sixel-cols options
have been added to enable the user to override the values
in case of failures with get_terminal_size2.
This commit also adds ability to handle video zoom correctly.
Whenever video-zoom is triggered, the src and dst rects
will be updated. Scaling seems to work well now.
Having them in the same line made it hard to read them in the man page
since they are formatted in the same way and they look as though they
are only one definition.
Recent versions of mpv have applied security checks to --playlist
that previously only existed if playlist files were played as an
input directly. This commit documents this change and how to work
around it, in the event that playlist files are trusted.
Apparently mpv supports loading config files from the same directory as
the mpv.exe. This is a fallback of some sort. It used the old_home
mechanism.
I want to add a warning if old_home exists, but that would always show
the warning on win32. Obviously we don't want that.
Add a separate exe_dir entry to deal with that.
Untested, but probably works.
Mistakenly reverted as part of the default configuration directory
location switch-back in aa18a8e1cd.
Separation of the mpv executable directory from old_path is a
good change now that we warn about the old_config directory also
existing.
Fixes#8232Fixes#8244Fixes#8262
This can be viewed at page 4 of the internal stats display (i or I).
CPU time report is the same as at lua.c, but untested - doesn't seem
to work on windows - also not for lua.
TL;DR: Set env MPV_LEAK_REPORT=1 to enable js memory reporting stats.
This also almost doubles the memory usage by js scripts.
For memory reporting, we don't have enough info by default, because
even when using a custom allocator, mujs doesn't report the old size
(on free or realloc) because it doesn't track this value, and as
a result we can't track the overall size.
Our option are either to track the size of each allocation on our own,
or use talloc which tracks this value.
However, using talloc for mujs allocations adds a considerable
overhead, and almost doubles(!) the overall memory used, because each
individual allocation includes a considerable talloc header, and mujs
does many small allocations.
So our solution is that by default we behave like previously - not
using a custom allocator with mujs, and stats does not display memory
usage for js scripts.
However, if the env var MPV_LEAK_REPORT is set to 1, then we use
a custom allocator with talloc and track/report memory usage.
We can't switch allocator at runtime, so an mpv instance either tracks
or doesn't track js scripts memory usage, according to the env var.
(we could use a property and apply it whenever a new script starts,
so that it could change for newly launched scripts, but we don't).
- Explain which properties are writeable.
- Mark edition-list/N/id as writable.
- Remove (R) from some read-only properties since none of the others
have it.
- Add osd-dimension/ to its subproperties.
- options/<name> isn't read-only.
- focused works on macOS because of 82eda2e. Though it shouldn't be
possible to observe it without raising VO_EVENT_FOCUS.
The picture type is explained in /usr/include/libavutil/avutil.h
Other subproperties in /usr/include/libavutil/frame.h
And there is a more detailed explanation for repeat_pict in
/usr/include/libavcodec/avcodec.h
When possible, refer to booleans with "Whether..." since it can refer to
both yes (using input.conf and mp.get_property) and true (using the JSON
IPC or mp.get_property_native/bool), else explicitly say yes/true.
Say "true" for subprocess and osd-overlay named arguments since you
can't use them in input.conf and you will typically use them with the
boolean true in the named arguments, like the subprocess example in the
manpage does (though the string "yes" also works).
Subproperties that can't be accessed with the / syntax like
demuxer-cache-state's bof-cached and eof-cached always return true,
never yes.
Based on the implementation of ffmpeg's sixel backend output written
by Hayaki Saito
https://github.com/saitoha/FFmpeg-SIXEL/blob/sixel/libavdevice/sixel.c
Sixel is a protocol to display graphics in a terminal. This commit
adds support to play videos on a sixel enabled terminal using libsixel.
With --vo=sixel, the output will be in sixel format.
The input frame will be scaled to the user specified resolution
(--vo-sixel-width and --vo-sixel-height) using swscaler and then
encoded using libsixel and output to the terminal. This method
requires high cpu and there are high frame drops for 720p and
higher resolution videos and might require using lesser colors and
have drop in quality. Docs have all the supported options listed
to fine tune the output quality.
TODO: A few parameters of libsixel such as the sixel_encode_policy
and the SIXEL_XTERM16 variables are hardcoded, might want to
expose them as command line options. Also the initialization
resolution is not automatic and if the user doesn't specify the
dimensions, it picks 320x240 as the default resolution which is not
optimal. So need to automatically pick the best fit resolution for
the current open terminal window size.
This allows keybindings such as:
a script-message-to console type "seek :0 absolute" 6
% script-message-to console type "seek absolute-percent" 6
The cursor position 0 isn't allowed because it has the weird effect of
filling the console with the text twice, leaving the cursor in the
middle.
Negative positions would put the cursor n characters before the end, and
positions greater than the text's length at the end. They seem to work
at first, but the console breaks when you move the cursor, so they
aren't allowed.
It seems that float values don't cause issues, but I'm using the
argument's floor anyway to be safe. Using >= 1 instead of > 0 ignores
values like 0.5.
This introduces the delete-watch-later-config command, to complement
write-watch-later-config. This is an alternative to #8141.
The general problem that this change is attempting to help solve has
been described in #336, #3169 and #6574. Though persistent playback
position of a single file is generally a solved problem, this is not
the case for playlists, as described in #8138.
The motivation is facilitating intermittent playback of very large
playlists, consisting of hundreds of entries each many hours
long. Though the current "watch later" mechanism works well - provided
that the files each occur only once in that playlist, and are played
only via that playlist - the biggest issue is that the position is
lost completely should mpv exit uncleanly (e.g. due to a power
failure). Existing workarounds (in the form of Lua scripts which call
write-watch-later-config periodically) fail in the playlist case, due
to the mechanism used by mpv to determine where within a playlist to
resume playback from.
The missing puzzle piece needed to allow scripts to implement a
complete solution to this problem is simply a way to clean up the
watch-later configuration that the script asked mpv to write using
write-watch-later-config. With that in place, scripts can then
register an end-file event listener, check the stop playback reason,
and in the "eof" and "stop" case, invoke delete-watch-later-config to
delete any saved positions written by write-watch-later-config. The
script can then proceed to immediately write a new one when the next
file is loaded, which altogether allows mpv to resume from the correct
playlist and file position upon next startup.
Because events are delivered and executed asynchronously,
delete-watch-later-config takes an optional filename argument, to
allow scripts to clear watch-later configuration for files after mpv
had already moved on from playing them and proceeded to another file.
A Lua script which makes use of this change can be found here:
https://gist.github.com/CyberShadow/2f71a97fb85ed42146f6d9f522bc34ef
(A modification of the one written by @Hakkin, in that this one takes
advantage of the new command, and also saves the state immediately
when a new file is loaded.)
The original documentation here is unclear, so let's describe the
behaviour we actually have. Inspired by wm4's updated docs but
obviously not identical because we're not changing any of the
behaviours.
Pointless feature that can be done with environment variables. It was
also implemented incorrectly and broke autoprobing.
This reverts commit 015b676875.
As per the client API, a client can connect to any arbitrary wayland
socket. mpv has always just passed NULL which connected to the
compositor currently in use, but one could just as easily pass the name
of a different socket (i.e. the value of WAYLAND_DISPLAY). Here, we just
expose this argument as a user configurable option. If the user passes a
socket name that does not exist, then print a warning and fall back to
NULL.
Picks up files like "cover.jpg". It's made part of normal external file
loading, so I'm adding 3 new options that are direct equivalents for the
options that control loading of external subtitle and audio files. Even
though I bet nobody wants them and they just increase confusion... I
guess the world is actually hell, so this outcome should be fine.
It prefers non-specific external files like "cover.jpg" over embedded
cover art. Not sure if that's wanted or unwanted.
There's some pain over explicitly marking such files as external
pictures. This is basically an optimization: in most cases, a heuristic
would treat an image file loaded with --external-file the same (it's a
heuristic because ffmpeg can't tell us whether something is an image or
a video). However, even with this heuristic, it would decode the cover
art picture again on each seek, which would essentially slow down
seeking in audio files. This bothered me greatly, which is why I'm
adding these additional options at all, and bothered with the previous
commit.
Fixes: #3056
on macOS 10.15 setting the activation policy behaves quite weirdly. the
call changes the current active App to a nameless process, which
probably also the reason that prevents the not focusing to work.
a workaround for that, is to refocus the previous active app.
Fixes#7725
Add a property that returns whether the window is focused, currently
only for X11 and Wayland.
My use cause for this is having an equivalent of pause-when-minimize.lua
for tiling window managers: make mpv play only while it's in the current
workspace or is focused (I'm fine with either one but prefer focus).
On X I do this by observing display-names, which is empty when the
rectangles of the display and mpv don't intersect, but on Wayland its
value doesn't change when mpv leaves the current workspace (and the same
check doesn't work since the geometries still intersect).
This could later be made writable as requested in #6252.
Note that on Wayland se shouldn't consider an unactivated window with
keyboard input focused.
The wlroots compositors I tested set activated after changing the
keyboard focus, so if you set wl->focused only in
keyboard_handle_enter() and keyboard_handle_leave() to avoid adding the
"has_keyboard_input" member, focused isn't set to true when first
opening mpv until you focus another window and focus mpv again.
Conversely, if that order can't be assumed for all compositors, we
should toggle wl->focused when necessary in keyboard_handle_enter() and
keyboard_handle_leave() as well as in handle_toplevel_config().
--audio-stream-silence is a shitty feature compensating for awful
consumer garbage, that mutes PCM at first to check whether it's
compressed audio, using formats advocated and owned by malicious patent
troll companies (who spend more money on their lawyers than paying any
technicians), wrapped in a wasteful way to make it constant bitrate
using a standard whose text is not freely available, and only rude users
want it. This feature has been carelessly broken, because it's
complicated and stupid. What would Jesus do? If not getting an aneurysm,
or pushing over tables with expensive A/V receivers on top of them, he'd
probably fix the feature. So let's take inspiration from Jesus Christ
himself, and do something as dumb as wasting some of our limited
lifetime on this incredibly stupid fucking shit.
This is tricky, because state changes like end-of-audio are supposed to
be driven by the AO driver, while playing silence precludes this. But it
seems code paths for "untimed" AOs can be reused.
But there are still problems. For example, underruns will just happen
normally (and stop audio streaming), because we don't have a separate
heuristic to check whether the buffer is "low enough" (as a consequence
of a network stall, but before the audio output itself underruns).
The render API replaced the opengl_cb API over 2 years ago. Since then,
the opengl_cb API was emulated on top of the render API. While it would
probably be reasonable to emulate these APIs until they're removed in an
eventual libmpv 2.0 bump, I have some non-technical reasons to disable
the API now.
The API stubs remain; they're needed for formal ABI compatibility.
Transparent windows on X11/EGL/native Mesa GL didn't work for various
reasons. From what I remember, the current code did work with nvidia at
least. Mesa has made attempts to fix this, but they never really made it
in.
But it turns out you can make EGL/Mesa list the EGLConfigs that use X11
RGBA visuals, and context_x11egl.c contains code that explicitly selects
them if alpha is requested (see pick_xrgba_config()).
The reason EGL/Mesa did not list them (and thus breaking transparency)
is because we requested a EGL_ALPHA_SIZE != 0 if alpha is requested. But
the transparent EGLConfigs use EGL_ALPHA_SIZE == 0. That's because EGL
doesn't actually support the concept of transparent windows; the alpha
size parameter is something else (memory rendering without FBOs or
something, I don't care enough to look up the real reasons).
This still won't work on Wayland. Every EGL backend needs platform
specific code. (Good job, EGL, such an awesome platform independent
standard.)
Fixes: #6590
Accepting ":" in addition to "," seems confusing and dumb. It only
causing problems when you want to pass a value that contains ":". Remove
support for ":", it is now treated like any other normal character. This
affects all options that are listed as "Key/value list" in the option
list.
It's possible that this breaks for someone who happened to use ":" as
separator. But this was undocumented, and never recommended. Originally,
the option treated many other characters in a special way, but this was
changed in commit a3d561f950. I'm, not sure why ":" was explicitly
included. Maybe because -the absurd -vf/--af syntax uses ":" as list
separator. But "," was always recommended and used in examples for
key/value options.
Fixes: #8021 (if you consider it a bug)
This allows users to control whether full dialogue subtitles are displayed
with an audio track already in their preferred subtitle language.
Additionally, this improves handling for the forced flag, automatically
selecting between forced and unforced subtitle streams based on the user's
settings and the selected audio.
Add support for reading a byte range from a stream via
the `slice://` protocol.
Syntax is `slice://start[-end]@URL` where end is a maximum
(read until end or eof).
Size suffixes support in `m_option` is reused so they can
be used with start/end.
This can be very useful with e.g. large MPEGTS streams with
corruption or time-stamp jumps or other issues in them.

Make it possible to feed a string to stdin of a subprocess. Out of
laziness, it can't be an arbitrary byte string. (Would require adding an
option type that takes in a Lua byte string.)
Do not set stdin of a subprocess to fd 0 (i.e. mpv's stdin) anymore,
because it makes things more consistent. Enabling stdin didn't make too
much sense in the first place, so this behavior change seems
justifiable.
win32 support missing.

(The recommendation is to add the document to the project git root, but
I'm against dumping such things into git. I'd rather replace the
Copyright full text files with links and move contribute.md to the wiki
than add the CCoC text as a file.)
Seems like this is requested all the time.
It seems libass allows out of range values, but does allows the subtitle
to go out of the screen at the bottom (only when moving it to the top
it's "clamped"). Too bad, don't do that then. The bitmap sub rendering
code on the other hand is under our control, and will not move a
subtitle out of the screen.
Fixes: #7986
Requested. Should be good for simple use cases. "sub2" is technically
inconsistent (since the option is called --secondary-sid), but fuck the
consistent name.
Uses the mechanism introduced in the previous commit. The hope was to
make auto-profiles easier to use, and to get rid of the need for
manually created inverse profiles. Not sure if the end result is useful.
Make it possible to restore from profiles by backing up the option
values before profile application. This is sort of like unapplying a
profile. Since there might be multiple ways to do this, a profile needs
to explicitly provide the "profile-restore" option, which specifies how
exactly this should be done.
This is a big mess. There is not natural way to do this. Profile
application is "destructive" and simply changes the values of the
options. Maybe one could argue that the option system should have
hierarchical "overlays" of profiles instead, where unset options will
use the value of the lower profiles. Options set interactively by the
user would be the top profile. Default values would be in the lowest
profile. You could unapply a profile by simply removing it from this
overlay stack.
But uh, let's not, so here's something stupid. It reuses some code used
for file local options to reduce code size. At least the overlay idea
would still be possible in theory, and could be added as another
profile-restore mode.
This is used by the following commit.
The callback now gets an object argument with defer/cont functions.
Like the lua code, the behavior is that each hook event allows at
most one continue, but nothing enforces the order of continuations
if more hook events arrive before prior ones were continued - which
is possible now with the defer option, but wasn't possible before
(continuation was synchronous from the hook event handler).
This can now opt to not continue a hook after the hook callback returns.
This makes it easier for scripts, and may make it unnecessary to run
reentrant event loops etc. for scripts that want to wait before
continuing while still running the event loop.
This is taken from a somewhat older proof-of-concept script. The basic
idea, and most of the implementation, is still the same. The way the
profiles are actually defined changed.
I still feel bad about this being a Lua script, and running user
expressions as Lua code in a vaguely defined environment, but I guess as
far as balance of effort/maintenance/results goes, this is fine.
It's a bit bloated (the Lua scripting state is at least 150KB or so in
total), so in order to enable this by default, I decided it should
unload itself by default if no auto-profiles are used. (And currently,
it does not actually rescan the profile list if a new config file is
loaded some time later, so the script would do nothing anyway if no auto
profiles were defined.)
This still requires defining inverse profiles for "unapplying" a
profile. Also this is still somewhat racy. Both will probably be
alleviated to some degree in the future.
scaletempo2 is a new audio filter for playing back
audio at modified speed and is based on chromium
commit 51ed77e3f37a9a9b80d6d0a8259e84a8ca635259.
It sounds subjectively better than the existing
implementions scaletempo and rubberband.
Add env and detach arguments. This means the command.c code must use the
"new" mp_subprocess2(). So also take this as an opportunity to clean up.
win32 support gets broken by it, because it never made the switch to the
newer function.
The new detach parameter makes the "run" command fully redundant, but I
guess we'll keep it for simplicity. But change its implementation to use
mp_subprocess2() (couldn't do this earlier, because win32).
Privately, I'm going to use the "env" argument to add a key binding that
starts a shell with a FILE environment variable set to the currently
playing file, so this is very useful to me.
Note: breaks windows, so for example youtube-dl on windows will not work
anymore. mp_subprocess2() has to be implemented. The old functions are
gone, and subprocess-win.c is not built anymore. It will probably work
on Cygwin.
This probably makes it much faster (I wouldn't know, I didn't run any
benchmarks ). Seems to work as well (although I'm not sure, it's not
like I'd perform rigorous tests).
The scale_zimg test seems to mysteriously treat color in fully
transparent alpha differently, which makes no sense, and isn't visible
(but makes the test fail). I can't be bothered with investigating this
more. What do you do with failing tests? Correct, you disable them. Or
rather, you disable whatever appears to cause them to fail, which is the
threading in this case.
This change follows mostly the tile_example.cpp. The slice size uses a
minimum of 64, which was suggested by the zimg author. Some of this
commit is a bit inelegant and weird, such as recomputing the scale
factor for every slice, or the way slice_h is managed. Too lazy to make
this more elegant.
zimg git had a regressio around active_region (which is needed by the
slicing), which was fixed in commit 83071706b2e6bc634. Apparently, the
bug was never released, so just add a warning to the manpage.
Mess this into the --geometry option, because I like to be
irresponsible. I considered adding a separate option, but at least this
allows me to defer the question how the hell this should work as
property (geometry simply and inherently does not).
Tested on IceWM only. Option equality test and string output not tested.
I'm tired of dealing with this frequent spawning of xdg-screensaver when
debugging and what not. xdg-screensaver was never a serious tool anyway,
it's more like some self-deprecating joke by FDO folks.
This will affect X11 on GNOME and other DEs. I'm singling out GNOME
though, because they are the ones actively sabotaging any sane
technical solutions and community cooperation.
I have been accused of taking it out on innocent GNOME users, while none
of this will reach GNOME developers. Of course that is not the
intention.
This can be used to make vo_libmpv render video to a memory buffer. It
only adds a new backend API that takes memory surfaces. All the render
API (such as frame rendering control and so on) is reused.
I'm not quite convinced of the usefulness of this, and until now I
always resisted providing something like this. It only seems to
facilitate inefficient implementation. But whatever.
Unfortunately, this duplicates the software rendering glue code yet
again (like it exists in vo_x11, vo_wlshm, vo_drm, and probably more).
But in theory, these could reuse this backend in the future, just like
vo_gpu could reuse the render_gl API.
Fixes: #7852
libplacebo exposes this feature already, because this particular type of
bug is unusually common in practice. Simply make use of it, by exposing
it as an option.
Could probably also bump the libplacebo minimum version to get rid of
the #if, but that would break debian oldoldstable or something.
Fixes#7867.
Apparently mpv supports loading config files from the same directory as
the mpv.exe. This is a fallback of some sort. It used the old_home
mechanism.
I want to add a warning if old_home exists, but that would always show
the warning on win32. Obviously we don't want that.
Add a separate exe_dir entry to deal with that.
Untested, but probably works.
XDG is stupid, so change back to the standard behavior. Unfortunately,
most users will now have the XDG one, so we will still need to load
this. (This is exactly the same problem as when XDG support was
introduced, just the other way around).
This should not affect any normal users. Hopefully I tested this well
enough; my intention is not to torment miserable XDG fans; they can keep
using their config dir if they want it.
This changes behavior in two cases:
- new users (now creates ~/.mpv/ instead of ~/.config/mpv/)
- users which have both directories
The latter case will behave subtly or obviously different, not sure.
Just fix your shit.
Extend the manpage with all the messy details, as far as I could reverse
engineer them from the code.
De-emphasize it, since a user should usually not use it. This _could_ be
used to make the cache seekable with --cache=no, but it's better and
more intuitive to use --cache=yes. As such, the only use of this is for
debugging. I'm not quite sure if this should be removed entirely, but I
still see some value in it (for example if you want the cache lookahead,
but you're using a stream where cache seeking is somehow broken).
Implementation copy/pasted from:
https://code.videolan.org/videolan/libplacebo/-/commit/f793fc0480f
This brings mpv's tone mapping more in line with industry standard
practices, for a hopefully more consistent result across the board.
Note that we ignore the black point adjustment of the tone mapping
entirely. In theory we could revisit this, if we ever make black point
compensation part of the mpv rendering pipeline.
This standard says we should use a value of 203 nits instead of 100 for
mapping between SDR and HDR.
Code copied from https://code.videolan.org/videolan/libplacebo/-/commit/9d9164773
In particular, that commit also includes a test case to make sure the
implementation doesn't break roundtrips.
Relevant to #4248 and #7357.
This affects "pull" AOs only: ao_alsa, ao_pulse, ao_openal, ao_pcm,
ao_lavc. There are changes to the other AOs too, but that's only about
renaming ao_driver.resume to ao_driver.start.
ao_openal is broken because I didn't manage to fix it, so it exits with
an error message. If you want it, why don't _you_ put effort into it? I
see no reason to waste my own precious lifetime over this (I realize the
irony).
ao_alsa loses the poll() mechanism, but it was mostly broken and didn't
really do what it was supposed to. There doesn't seem to be anything in
the ALSA API to watch the playback status without polling (unless you
want to use raw UNIX signals).
No idea if ao_pulse is correct, or whether it's subtly broken now. There
is no documentation, so I can't tell what is correct, without reverse
engineering the whole project. I recommend using ALSA.
This was supposed to be just a simple fix, but somehow it expanded scope
like a train wreck. Very high chance of regressions, but probably only
for the AOs listed above. The rest you can figure out from reading the
diff.
This simply printf()s a concatenation of the provided string and the
relevant escape sequences. No idea what exactly defines this escape
sequence (is it just a xterm thing that is now supported relatively
widely?), and this simply uses information provided on the linked github
issue.
Not much of an advantage over --term-status-msg, though at least this
can have a lower update frequency. Also I may consider setting a default
value, and then it shouldn't conflict with the status message.
Fixes: #1725
This mode drops or repeats audio data to adapt to video speed, instead
of resampling it or such. It was added to deal with SPDIF. The
implementation was part of fill_audio_out_buffers() - the entire
function is something whose complexity exploded in my face, and which I
want to clean up, and this is hopefully a first step.
Put it in a filter, and mess with the shitty glue code. It's all sort of
roundabout and illogical, but that can be rectified later. The important
part is that it works much like the resample or scaletempo filters.
For PCM audio, this does not work on samples anymore. This makes it much
worse. But for PCM you can use saner mechanisms that sound better. Also,
something about PTS tracking is wrong. But not wasting more time on
this.
Can be useful to force it to adapt to extreme speed changes, while a
higher limit would just use a fraction closer to the original video
speed.
Probably useful for testing only.
Remove the vaguely defined plane_bits and component_bits fields from
struct mp_imgfmt_desc. Add weird replacements for existing uses. Remove
the bytes[] field, replace uses with bpp[].
Fix some potential alignment issues in existing code. As a compromise,
split mp_image_pixel_ptr() into 2 functions, because I think it's a bad
idea to implicitly round, but for some callers being slightly less
strict is convenient.
This shouldn't really change anything. In fact, it's a 100% useless
change. I'm just cleaning up what I started almost 8 years ago (see
commit 00653a3eb0). With this I've decided to keep mp_imgfmt_desc,
just removing the weird parts, and keeping the saner parts.
Before this, we pretty much guaranteed that --mpv-ipc-fd=3 would be
passed. The FD was hardcoded, so scripts started by this mechanism
didn't need to actually parse the argument. Change this to using a
mostly random FD number instead.
I decided to do this because posix_spawnp() and the current replacement
cannot "guarantee" a FD layout. posix_spawn_file_actions_adddup2() just
runs dup2() calls, so it may be hard to set FD 3/4 if they are already
used by something else. For example imagine trying to map:
{.fd = 3, .src_fd = 4},
{.fd = 4, .src_fd = 3},
Then it'd do dup2(4, 3), dup2(3, 4) (reminder: dup2(src, dst)), and the
end result is that FD 4 really maps to the original FD 4.
While this was not a problem in the present code, it's too messy that I
don't want to pretend it can always done this way without an unholy
mess. So my assumption is that FDs 0-2 can be freely assigned because
they're never closed (probably...), while for all other FDs only
pass-through is reasonable.
See manpage additions. This was requested, sort of. Although what has
been requested might be something completely different. So this is
speculative.
This also changes sub_get_text() to return an allocated copy, because
the buffer shit was too damn messy.
As discussed in the referenced issue. This is quite a behavior change,
bit since this option is new, and not included in any releases yet, I
think it's OK.

This isn't useful anymore. We have a much better d3d11 renderer in
vo_gpu. D3D11 is available in all supported Windows versions. The
StretchRect path might still be useful for someone (???), and leaving it
at least evades conflict about users who want to keep using this VO for
inexplicable reasons. (Low power usage might be a justified reason, but
still, no.)
Also fuck the win32 platform, it's a heap of stinky shit. Microsoft is
some sort of psycho clown software company. Granted, maybe still better
than much of the rest of Silly Con Valley.
By default --sub-auto uses "exact". This was far from an "exact" match,
because it added anything that started with the video filename (without
extension), and seemed to end in something that looked like a language
code.
Make this stricter. "exact" still tolerate a language code, but the
video's filename must come before it without any unknown extra
characters. This may not load subtitles in some situations where it
previously did, and where the user might think that the naming
convention is such that it should be considered an exact match.
The subtitle priority sorting seems a bit worthless. I suppose it may
have some value in higher "fuzz" modes (like --sub-auto=fuzzy).
Also remove the mysterious "prio += prio;" line. I probably shouldn't
have checked, but it goes back to commit f16fa9d31 (2003), where someone
wanted to "refine" the priority without changing the rest of the code or
something.
Mostly untested, so have fun.

I have to say this in PR reviews all the time, so maybe I should make i
explicit. In too many words of course, many, many, too many words which
nobody will read, I get it, now shut up. Sneak in some subtle or not so
subtle comments about how I think that github is ruining code quality.
This is mostly for testing. It adds passing through the metadata through
the video chain. The metadata can be manipulated with vf_format. Support
for zimg alpha conversion (if built with zimg after it gained alpha
support) is implemented. Support premultiplied input in vo_gpu.
Some things still seem to be buggy.
Consider e.g. --aid=2 with a file that has only 1 track. Then it would
fall back to selecting track 1. Stop doing this. If no matching track is
found, this will not select any track now.
Note that the fingerprint stuff (track_layout_hash in the source)
prevents softens the impact of this change. Without the fingerprint,
playing a dual-audio file with the second track selected, and then a
single-audio file, would play the second file without audio. But the
fingerprint resets it due to differences in the track list.
Try to exhaustively document this and tricky interactions between the
other features. What a damn mess, I think it's simply cursed. Of course
it's still my fault.
See: #7608
Some time ago, properties and options were mostly unified. However, the
track selection properties/options semantics are incompatible to this
change. I'm still trying to handle the fallout.
There are two things that are in the way:
1. Track properties somehow return the runtime selection, not the option
value (all while properties are supposed to be aliases to options
with the same name).
2. The user's track options are not supposed to be changed without
interaction. If a track is auto-selected, the property should return
its ID, but the option value should remain at "auto". Only if the
user actually writes to the property the option should change. E.g.
playing e.g. an audio-only file and then a normal video file not play
the video file with --vid=no just because the audio file had no video
track.
In addition to each of them being in conflict with the property/option
unification, attempt to fix one of them breaks the other one.
Today, we're trying to fix parts of this and avoiding an unfortunate
case where you can get a conflicting option/property value, and where
trying to select a track does nothing if the track to select has the
same ID as the option value.
This breaks 2. from above in certain situations. See manpage additions.
See: #7608
This sucks, but is helpful for testing.
Obviously, it would be much nicer if there were a way to specify _all_
scaler options per filter (if the user wanted), instead of always using
the global options. But this is "too hard" for now. For testing, it is
extremely convenient to select the scaler backend, so add this option,
but make clear that it could go away. We'd delete it once there is a
better mechanism for this.
Keys and lines-to-scroll are configurabe, and the scroll keys are only
bound on pages which support scrolling (currently only page 4) - also
during oneshot (like the page-switching keys).
Scroll offset is reset for all pages on any key - except scroll keys, so
that entering or switching to a page resets the scroll, as well as when
"re-entering" the same page or "re-activating" the stats oneshot view.
TODO: print_page(..) is highly associated with extending the oneshot
timer if required. The timer handling can probably move into print_page
and removed from all the places which boilerplate its management.
While --input-file was removed for justified reasons, wanting to pass
down socket FDs this way is legitimate, useful, and easy to implement.
One odd thing is that

Add an infrastructure for collecting performance-related data, use it in
some places. Add rendering of them to stats.lua.
There were two main goals: minimal impact on the normal code and normal
playback. So all these stats_* function calls either happen only during
initialization, or return immediately if no stats collection is going
on. That's why it does this lazily adding of stats entries etc. (a first
iteration made each stats entry an API thing, instead of just a single
stats_ctx, but I thought that was getting too intrusive in the "normal"
code, even if everything gets worse inside of stats.c).
You could get most of this information from various profilers (including
the extremely primitive --dump-stats thing in mpv), but this makes it
easier to see the most important information at once (at least in
theory), partially because we know best about the context of various
things.
Not very happy with this. It's all pretty primitive and dumb. At this
point I just wanted to get over with it, without necessarily having to
revisit it later, but with having my stupid statistics.
Somehow the code feels terrible. There are a lot of meh decisions in
there that could be better or worse (but mostly could be better), and it
just sucks but it's also trivial and uninteresting and does the job. I
guess I hate programming. It's so tedious and the result is always shit.
Anyway, enjoy.
That's where it comes from after all. The other property does not have
much of a reason to exist anymore, but there's no real reason to remove
it either.
Ancient Linux audio output. Apparently it survived until now, because
some BSDs (but not all) had use of this. But these should work with
ao_sdl or ao_openal too (that's why these AOs exist after all). ao_oss
itself has the problem that it's virtually unmaintainable from my point
of view due to all the subtle (or non-subtle) difference. Look at the
ifdef mess and the multiple code paths (that shouldn't exist) in the
removed source code.
I wonder what this even is. I've never heard of anyone using it, and
can't find a corresponding library that actually builds with it. Good
enough to remove.
It was always marked as "experimental", and had inherent problems that
were never fixed. It was disabled by default, and I don't think anyone
is using it.
May or may not help when dealing with playlist loading in scripts. It's
supposed to help with the mean fact that loading a recursive playlist
will essentially edit the playlist behind the API user's back.
Scripts such as the OSC can be loaded and unloaded at runtime by
toggling the option that enables them. (It even works, although normally
it's only used to control initial loading.)
Unloading was racy because it used the client name; fix this.
The load-script change is an accidental feature. And probably useless.
I mostly intend this for internal purposes. Probably pretty useless for
external API users, but on the other hand trivial to expose. While it
makes a lot of sense internally, I'll probably regret exposing it.
Lua changed behavior for this specific event. I considered the change
minor enough that it would not need to go through deprecation, but
someone hit it immediately and ask on the -dev channel.
It's probably better to restore the behavior. But mark it as deprecated,
since it's problematic (mismatch with the C API). Unfortunately, no
automatic warning is possible. (Or maybe it is, by playing sophisticated
Lua tricks such as setting a metatable and overriding indexing, but
let's not.)
Move some parts that can be generic to the client API code. It turns out
lua.c doesn't need anything special.
This adds the "id" field. I think this was actually missing from the
JSON IPC code (i.e. it's a very recent regression that is fixed with
this commit).
Both Lua and the JSON IPC code need to convert the mpv_event struct (and
everything it points to) to Lua tables or JSON.
I was getting sick of having to make the same changes to Lua and IPC. Do
what has been done everywhere else, and let the core handle this by
going through mpv_node (which is supposed to serve both Lua tables and
JSON, and potentially other scripting language backends). Expose it as
new libmpv API function.
The new API is still a bit "rough" and support for other event types
might be added in the future.
This silently adds support for the playlist_entry_id fields to both Lua
and JSON IPC.
There is a small API change for Lua; I don't think this matters, so I
didn't care about compatibility. The new code in client.c is mashed up
from the Lua and the IPC code. The manpage additions are moved from the
Lua docs, and made slightly more "general".
Some danger for unintended regressions both in Lua and IPC. Also damn
these node functions suck, expect crashes due to UB.
Not sure why this became more code instead of less compared to before
(according to the diff stat), even though some code duplication across
Lua and IPC was removed. Software development sucks.
Should give a good deal more explicit control and insight over the
player state.
Some feel a bit pointless, and/or expose internal weirdness. However,
it's not like the existing weirdness didn't exist before, or can be made
go away. (In part, the weirdness is because certain in-between states
are visible. Hiding them would make things simpler, but less flexible.)
Maybe this actually gives users a better idea how the API _should_ look
like, too.
On a side note, this tries to really guarantee that mpctx->playing is
set between playback start/end. For that, the loadfile.c changes assume
that mpctx->playing is set (guaranteed by code above the change), and
that playing->filename is set (probably could never be false; was broken
before and actually would have crashed if that could ever happen; in any
case, also add an assert to playlist.c for this).
playlist_entry_to_index() now tolerates playlist_entrys that are not
part of the playlist. This is also needed for mpctx->playing.
It's odd that this state is observable, but is made implicit by making
the property unavailable. It's also odd that an API user cannot directly
put the player into such a state.
Just allow reading/writing -1 (or in fact, any out of bounds index) for
this case.
I'm also refraining from using OPT_CHOICE for the "no selection" case,
because although that would be cleaner in theory, it would cause only
problems to API users due to the more complex property type (worse is
better).
One reason for not restricting the integer range on the input property
anymore is that if there are no playlist elements, the range would
contain only 1 integer, which cannot be represented anymore since the
recent m_option change. This was actually broken with 1 element
playlists before (and still is, with the constricted type for OSD and
the add/cycle commands). Doesn't matter too much.
If the user manages to run a "loadfile x append" command before the loop
in mp_play_files() is entered, then the player could start playing
these. This isn't expected, because appending files to the playlist in
idle mode does not normally start playback. It could happen because
there is a short time window where commands are processed before the
loop is entered (such as running the command when a script is loaded).
The idle mode semantics are pretty weird: if files were provided in
advance (on the command line), then these should be played immediately.
But if idle mode was already entered, and something is appended to the
playlist using "append", i.e. without explicitly triggering playback,
then it should remain in idle mode.
Try to follow this by redefining PT_STOP to strictly mean idle mode.
Remove the playlist->current check from idle_loop(), since only the
stop_play field counts now (cf. what mp_set_playlist_entry() does).
This actually introduces the possibility that playlist->current, and
with it playlist-pos, are set to something, even though playback is not
active or being started. Previously, this was only possible during state
transitions, such as when changing playlist entries.
Very annoyingly, this means the current way MPV_EVENT_IDLE was sent
doesn't work anymore. Logically, idle mode can be "active" even if
idle_loop() was not entered yet (between the time after mp_initialize()
and before the loop in mp_play_files()). Instead of worrying about this,
redo the "idle-active" property, and deprecate the event.
See: #7543
Change all OPT_* macros such that they don't define the entire m_option
initializer, and instead expand only to a part of it, which sets certain
fields. This requires changing almost every option declaration, because
they all use these macros. A declaration now always starts with
{"name", ...
followed by designated initializers only (possibly wrapped in macros).
The OPT_* macros now initialize the .offset and .type fields only,
sometimes also .priv and others.
I think this change makes the option macros less tricky. The old code
had to stuff everything into macro arguments (and attempted to allow
setting arbitrary fields by letting the user pass designated
initializers in the vararg parts). Some of this was made messy due to
C99 and C11 not allowing 0-sized varargs with ',' removal. It's also
possible that this change is pointless, other than cosmetic preferences.
Not too happy about some things. For example, the OPT_CHOICE()
indentation I applied looks a bit ugly.
Much of this change was done with regex search&replace, but some places
required manual editing. In particular, code in "obscure" areas (which I
didn't include in compilation) might be broken now.
In wayland_common.c the author of some option declarations confused the
flags parameter with the default value (though the default value was
also properly set below). I fixed this with this change.
Commits ba70b150fb and 8a4f812b76 should have mentioned this. These
things should be quite useful for client API users, and thus should be
mentioned in a prominent place.
Although I'm not sure if anyone will understand from this gibberish what
this really means.
When the current file changes (or rather, when starting/finishing
playback of a playlist entry), clients tend to have the problem that
it's hard to tell whether a property change notification (via
mpv_observe_property() and mechanisms layered on top of it) is from the
previous or new playlist entry. The previous commit probably helps, but
all the asynchronity is still a bit unhelpful.
Try to make this better by adding new hooks, that are run before/after
playback init/deinit. This is similar to the existing hooks, except
they're outside of "initialized" playback, which excludes that you might
accidentally get an overlap between the current and the previous/next
playlist entry.
That still doesn't seem quite enough, since normally, property change
notifications come after the hook event. So basically a client would
have to explicitly "drain" the event queue within the hook, and make the
hook continue only after that is done. Knowing when property
notifications are done is another asynchronous nightmare (how exactly it
works keeps changing within client.c, and an API user probably can't
tell anymore when all pending properties are truly done). So introduce
another guarantee: properties that were changed before the hook happens
will be returned before the hook event is returned. That means the
client will have received all pending property notifications from the
previous playlist entry (or whatever) before the hook is entered.
As another minor complication, we shouldn't just keep the hook pending
until _all_ property notifications are done, since the client's hook
could produce new ones. (Or just consider things like the demuxer thread
hammering the client with cache update events, while the "on_preloaded"
hook is run.) So there is some extra untested, fragile logic in client.c
to handle this (the waiting_for_hook flag).
This probably works, but was barely tested. Not sure if this helps
anyone, but I think it's fine for my own purposes. (I really hated this
aspect of the API whenever I used it myself.)
No replacement. Qt or C++ code has no business in this repository, and
new code (even if it uses Qt) should not use it. Get rid of it.
We consider the libmpv API itself as stable. Symbols can be deprecated,
but not be removed. However, qthelper.hpp was never considered part of
the libmpv API. There no ABI implications either, since it's a header-
only implementation that uses C API symbols only. It's just a header
provided for convenience for Qt/C++ programs (i.e. extremely limited
usefulness).
This is more or less a minimal hack to make _some_ text measurement
functionality available to scripts. Since libass does not support such a
thing, this simply uses the bounding box of the rendered text.
This is far from ideal. Problems include:
- using a bitmap bounding box
- additional memory waste and/or flushing caches
- dependency on window size
- odd small deviations with different window sizes (run osd-test.lua and
resize the window after each timer update; the bounding boxes aren't
adjusted in an overly useful way)
- inability to query the size _after_ actual rendering
But I guess it's a start. Since I'm aware that it's crap, add a threat
to the manpage that this may be changed/removed again. For now, I'm
interested whether anyone will have use for it in its current form, as
it's an often requested feature.
The mp_filter_run() invocation blocks as long as the demuxer provides
packets and the queue can be filled. That means it may block quite a
long time of the decoder queue size is large (since we use libavcodec in
a blocking manner; it regrettably does not have an async. API).
This made the main thread freeze in certain situations, because it has
to wait on the decoder thread.
Other than I suspected (I wrote that code, but that doesn't mean I know
how the hell it works), this did not freeze during seeking: seek resets
flushed the queue, which also prevented the decoder thread from adding
more frames to it, thus stopping decoding and responding to the main
thread in time. But it does fix the issue that exiting the player waited
for the decoder to finish filling the queue when stopping playback.
(This happened because it called mp_decoder_wrapper_set_play_dir()
before any resets. Related to the somewhat messy way play_dir is
generally set. But it affects all "synchronous" decoder wrapper API
calls.)
This uses pretty weird mechanisms in filter.h and dispatch.h. The
resulting durr hurr interactions are probably hard to follow, and this
whole thing is a sin. On the other hand, this is a _very_ user visible
issue, and I'm happy that it can be fixed in such an unintrusive way.
I don't know what should happen when the same value is written to the
property. It seems that it would be more natural if it were ignored
(since that's also what is done with options now), but you could argue
the other way around as well. In any case, changing it silently could
leads to user scripts etc. breaking, so don't change it now.
Instead, add blabla to the manpage to put the responsibility on the
user, so when we suddenly change it one day, we can blame any breakages
on someone else.
See: #7501
Let's see how much everyone hates this. Leaving it enabled seems
problematic, because libavcodec returns an unspecific error if it
doesn't like it.
Fixes: #6300
See manpage additions. This has been a topic in MPlayer/mplayer2/mpv
since forever. But since libavcodec multi-threaded decoding was added,
I've always considered this pointless. libavcodec requires you to
"preload" it with packets, and then you can pretty much avoid blocking
on it, if decoding is fast enough.
But in some cases, a decoupled decoder thread _might_ help. Users have
for example come up with cases where decoding video in a separate
process and piping it as raw video to mpv helped. (Or my memory is
false, and it was about vapoursynth filtering, who knows.) So let's just
see whether this helps with anything.
Note that this would have been _much_ easier if libavcodec had an
asynchronous (or rather, non-blocking) API. It could probably have
easily gained that with a small change to its multi-threading code and a
small extension to its API, but I guess not.
Unfortunately, this uglifies f_decoder_wrapper quite a lot. Part of this
is due to annoying corner cases like legacy frame dropping and hardware
decoder state. These could probably be prettified later on.
There is also a change in playloop.c: this is because there is a need to
coordinate playback resets between demuxer thread, decoder thread, and
playback logic. I think this SEEK_BLOCK idea worked out reasonably well.
There are still a number of problems. For example, if the demuxer cache
is full, the decoder thread will simply block hard until the output
queue is full, which interferes with seeking. Could also be improved
later. Hardware decoding will probably die in a fire, because it will
run out of surfaces quickly. We could reduce the queue to size 1...
maybe later. We could update the queue options at runtime easily, but
currently I'm not going to bother.
I could only have put the lavc wrapper itself on a separate thread. But
there is some annoying interaction with EDL and backward playback shit,
and also you would have had to loop demuxer packets through the
playloop, so this sounded less annoying.
The food my mother made for us today was delicious.
Because audio uses the same code, also for audio (even if completely
pointless).
Fixes: #6926
The "seekbarkeyframes" option is now interpreted such if it's true, the
player default is used. Too lazy to make this a choice option or
whatever; the Lua option parser doesn't have support for that anyway.
Someone who cares can adjust this.
Try to deal with various corner cases. But when I fix one thing, another
thing breaks. (And it's 50/50 whether I find the breakage immediately or
a few months later.) So results may vary.
The default for--hr-seek is changed to "default" (not creative enough to
find a better name). In this mode, audio seeking is exact if there is no
video, or if the video has only a single frame. This change is actually
pretty dumb, since audio frames are usually small enough that exact
seeking does not really add much. But it gets rid of some weird special
cases.
Internally, the most important change is that is_coverart and is_sparse
handling is merged. is_sparse was originally just a special case for
weird .ts streams that have the corresponding low-level flag set. The
idea is that they're pretty similar anyway, so this would reduce the
number of corner cases. But I'm not sure if this doesn't break the
original intended use case for it (I don't have a sample anyway).
This changes last-frame handling, and respects the duration of the last
frame only if audio is disabled. This is mostly "coincidental" due to
the need to make seeking past EOF trigger player exit, and is caused by
setting STATUS_EOF early. On the other hand, this might have been this
way before (see removed chunk close to it).
This is useful with live streams, and it's not much worse than the h264
first packet hack, which reads some data anyway.
For some reason, the option wasn't even documented, so do that.
In addition, print the start time even if it's negative. That should not
be possible, but for some reason, the field is an int64_t copied from an
uint64_t so... whatever. Keeping the logging slightly more straight
forward is better anyway.
Remove some redundant fields that controlled or indicated whether the
demuxer was/could/should prefetch. Redefine how the eof/reading fields
work.
The in->eof field is now always valid, instead of weirdly being reset to
false in random situations. The in->reading field now corresponds to
whether the demuxer thread is working at all, and is reset if it stops
doing anything.
Also, I always found it stupid that dequeue_packet() forced the demuxer
thread to retry reading if it was EOF. This makes little sense, but was
probably added for files that are being appended to (running downloads).
It makes no sense, because if the cache really tried to read until file
EOF, it would encounter partial packets and throw errors, so all is lost
anyway. Plus stream_file now handles this better. So stop this behavior,
but add a temporary option that enables the old behavior.
I think checking for ds->eager when enabling prefetching never really
made sense (could be debated, but no, not really). On the other hand,
the change above exposed a missing wakeup in the backward demuxing code.
Some chances of regressions that could make it stuck in certain states
or so, or incorrect demuxer cache state reporting to the player
frontend.
This has been part of the libmpv for a while, so the implementation in
the IPC code is quite simple: just pass the mpv_node representing the
value of the "command" field without further checks to
mpv_command_node().
The only problem are the IPC-specific commands, which essentially have
their own dispatch mechanism. They expect an array. I'm not going to
rewrite the dispatch mechanism, so these still work only with an array.
I decided make the other case explicit with cmd==NULL. (I could also
have set cmd=="", which would have avoided changing each if condition
since "" matches no existing command, but that felt dirty.)
I decided to make this explicit. The alternative would have been making
all commands asynchronous always, like a small note in the manpage
threatened. I think that could have caused compatibility issues.
As a design decision, this does not send a reply if an async command
started. This could be a good or bad idea, but in any case, it will make
async command look almost like synchronous ones, except they don't block
the IPC protocol.
In all_formats mode, we've ignored what --ytdl-format did so far, since
we've converted the full format list, instead of just the formats
selected by youtube-dl.
But we can easily restore --ytdl-format behavior: just mark the selected
tracks as default tracks.
I don't think the skip_muxed option was overlay useful. While it was
nice to filter out the low quality muxed versions (as it happens on the
alphabetic site, I suspect it's compatibility stuff), it's not really
necessary, and just makes for another tricky and rarely used
configuration option. (This was different before muxed tracks were also
delay-loaded, and including the muxed versions slowed down loading.)
Add the force_all_formats option instead, which handles the HLS case.
Set it to true because they are also delay-loaded now, and don't slow
down startup as much.
Until now, delay-loading was for files with single tracks only
(basically what DASH and HLS like to expose, so adaptive streaming and
codec selection becomes easier - for sites, not for us). But they also
provide some interleaved versions, probably for compatibility. Until
now, we were forced to eagerly load it (making startup slightly slower).
But there is not much missing. We just need a way to provide multiple
metadata entries, and use them to represent each track.
A side effect is now that the "track_meta" header can be used for normal
EDL files too.
See manpage additions. We would have to extend delay_open to support
multiple sub-tracks (for audio and video), and we'd still don't know (?)
whether it might contain more than one stream each (thinking of HLS
master streams). And if it's a true interleaved file (such as a "normal"
mp4 file provided as fallback for more primitive players), we'd either
have to signal such "bundled" tracks, or waste bandwidth.
This restructures a lot. The if/else tree in add_single_video for format
selection was a bit annoying, so it's split into separate if blocks,
where it checks each time whether a URL was determined yet.
This is just a more convenient way to start IPC client scripts per mpv
instance.
Does not work on Windows, although it could if the subprocess and IPC
parts are implemented (and I guess .exe/.bat suffixes are required).
Also untested whether it builds on Windows. A lot of other things are
untested too, so don't complain.
Pretty worthless I guess. I only tested one site (and 2 videos), it's
somewhat likely that it will break with other sites. Even if you leave
the option disabled (the default).
Slightly related to #3548. This will allows you to use the bitrate
stream selection mechanism, that was added for HLS, with normal videos.
Works as ad-filter. I had some more plans, for example replacing
matching text with different text, but for now it's dropping matches
only. There's a big warning in the manpage that I might change
semantics. For example, I might turn it into a primitive sed.
In a sane world, you'd probably write a simple script that processes
downloaded subtitles before giving them to mpv, and avoid all this
complexity. But we don't live in a sane world, and the sooner you learn
this, the happier you will be. (But I also want to run this on muxed
subtitles.)
This is pretty straightforward. We use POSIX regexes, which are readily
available without additional pain or dependencies. This also means it's
(apparently) not available on win32 (MinGW). The regex list is because I
hate big monolithic regexes, and this makes it slightly better.
Very superficially tested.
This renders incorrectly in the html output. I suspect you need one more
level here. Increase the indentation level. No other changes, other than
re-breaking some lines.
Add something that will access an URL embedded in EDL only when the
track it corresponds to is actually selected. This is meant to help with
ytdl_hook.lua and to improve loading speeds.
In theory, all this stuff is available to any mpv user, but discourage
using it, as it's so specialized towards ytdl_hook.lua, that there's
danger we'll just break this once ytdl_hook.lua stops using it, or
similar.
Mostly untested.
Normally, the first sub-stream is implicitly created. This change lets
the user use more orthogonal syntax, and use a new_stream header for
every sub-stream, instead of having to skip the header for the first
one.
Add a mp_log context to the parse_edl() function, and report some
errors. Previously, this just told you that something was wrong. Add
some error reporting to make it slightly less evil.
Put all parameters in a list before processing them. This makes adding
parameters for special headers easier, and we can report parameters that
were not understood. (For "compatibility", which probably doesn't matter
at all, still don't count them as errors; as before.)
As requested I guess. It behaves quite similar to the --loop* options.
Not quite happy with the idea that 1) the option is mutated on each
operation (but at least it's consistent with --loop* and doesn't require
more properties), and 2) the ab-loop command will do nothing once all
loop iterations are done. As a concession, the OSD shows something about
"disabled".
Fixes: #7360
This is not really a changelog, but rather a list of potentially
breaking changes API- and normal users should be aware of, and to help
with migration from older mpv releases.
this creates a default log for the last mpv run when started from the
bundle. that way one can get a log of what happened even after an issue
occurred. also add a menu entry under Help to show the current log, but
only when the bundle is used.
Fixes#7396Fixes#2547
Directories inside ~~/scripts/ are now loaded as scripts, so don't use
it also for modules. Now there are no default module paths.
To compensate, we now try to run ~~/.init.js right after defaults.js,
so the user may extend the js init procedure via this script, e.g. for
adding default paths to mp.module_paths .
See #7435 and related for context.
Basically, it seems that while the original vsfilter processed subtitles
like with this option set to "yes", many current players (mpc-hc
default, vlc, probably most libass users) treat them like with "no". In
the linked issue, this makes rendering severely slower, and can consume
a lot of memory (or just overflow libass memory calculations). It seems
that changing this to "no" will lead to more good than bad, especially
because newer subtitles may be authored for the "no" behavior.
Most libass users seem to use "no" exactly because they do not call
ass_set_storage_size() at all. This API was needed because the scaling
of the subtitles depends on the video size (vsfilter bugs, or
something). In addition, it's my personal opinion that rendering should
not depend on the video at all, so I like setting the default of this to
"no".
