Page 2 displays the frame timing info for each type (currently "Fresh"
and "Redraw"), but since they're unordered keys of a map, their
iteration order and hence their order on screen could (and did) change
depending on $things, which was annoying.
haasn thinks none of them should be considered more important (and
therefore maybe worthy of being displayed on top), so we go with
lexicographic order, which currently means that "Fresh" is first.
Fixes#9901
This fixes two potential divisions by 0 at generate_graph(...):
- If v_avg is (given and) 0.
- if v_max is 0.
The former doesn't seem to happen in practice because v_avg is only
used at one generate_gpah call, where it's apparently not 0.
The latter triggers if all the graph values are 0 (hence v_max is
also 0).
The implication of these divisions by 0 is an invalid y-value which
ends up at the ASS coordinates string for the graph inner content.
On linux the value ends as "nan" (luajit) or "-nan" (lua 5.1/5.2), and
on Windows it's "nan" (luajit) or "-1.#IND00" (lua 5.1/5.2), maybe due
to msvcrt's snprintf.
All these strings are wrong as ASS numbers, but due to luck in how
libass parses the coordinates, "nan" and "-nan" result in empty graph
(which looks OK for "all values are 0"), while "-1.#IND00" is parsed
as -1, which breaks the graph rendering (affects other graphs too).
One example of "all values are 0" is at page 0 (internal performance
graphs) on Windows - because the cpu metrics don't work.
So this fixes at least page 0 on Windows with lua 5.1/5.2.
While at it, move the scale calculations to one place, which now
avoids division by 0, instead of duplicating this calculation.
In the future, we can consider improving the generate_graph API:
- It needs one peak value, but takes 3 (v_max, v_avg, scale) which
are meshed into one final value.
- v_avg is only used in 1 of 6 call sites, but at the middle of the
arguments, so all other call sites need to pass explicit "nil".
- "scale" is arbitrary and used to leave some space at the top of the
graph. 5 places use 0.8, one uses 0.9. Could probably be unified.
Render subs at the output resolution, rather than the video resolution.
Uses the new APIs found in libplacebo 197+, to allow controlling the OSD
resolution even for image-attached overlays.
Also fixes an issue where the overlay state did not get correctly
updated while paused. To avoid regenerating the OSD / flushing the cache
constantly, we keep track of OSD changes and only regenerate the OSD
when the OSD state is expected to change in some way (e.g. resolution
change). This requires introducing a new VOCTRL to inform the VO when
the UPDATE_OSD-tagged options have changed.
Fixes#9744, #9524, #9399 and #9398.
The stop-screensaver option is currently limited to a simple yes/no
option. While the no option does always disable mpv trying to stop the
screensaver, yes does not mean the screensaver is always stopped. The
screensaver will be enabled again depending on certain conditions (like
if the player is paused). Simply introduce a new value for this option,
always, which does exactly what the name implies: the screensaver will
always be disabled.
This speeds up chapter name access while hovering the seekbar:
- Fetch the chapter-list property using observation rather than on
every render while hovering the bar. Property access, especially
with potentially lots of values (chapters), can be expensive-ish,
and can involve locking, so the less per-render the better.
- Sort the list once (on change) to simplify the iteration logic when
searching the chapter which matches the mouse position. It's still
O(N) (no binary search currently), but with less work.
The cached sorted list is stored at the state. While there are other
places which access this property and could use this cache, for now we
don't touch them, because they're not performance-critical (on init
for the chapter markers, on ch_{prev,next} button click for OSD).
Caching properties using observation instead of using mp.get_property
can indeed speedup other places too, but it should be part of a system
rather than implemented per-property. Maybe some day.
When utils.get_user_path was added, the expand-path command didn't
exist. Now it does, so remove the C code, make it a trivial wrapper.
Keep this function for backward compat to not break scripts, but
technically it's not required anymore.
The code assumed that the value of the profile-restore field is
"default" for such profiles, but the C implementation is such
that the field is intentionally omitted in such case.
This resulted in incorrectly trying to restore such profiles. However,
there are no stored values with profile-restore=default, so it only
resulted in a harmless warning, but otherwise behaved correctly (i.e.
nothing is restored).
Fix the condition by taking into account that missing field means
"default", so that it doesn't try to restore in such case, and
avoid the warning.
This reverts commit 04f0b0abe4.
It's not a good idea to unify the names only for visibility, while
keeping secondary-* for everything else.
This needs a bit more thought before we allow secondary sub to be
visible on its own.
Adds --sub-visibility choices 'primary-only' for only displaying the
primary subtitle track, and 'secondary-only' for only displaying
secondary subtitle track.
Removes --secondary-sub-visibility and displays a message telling the
user to use --sub-visibility=yes/primary-only instead.
These changes make it so that the default 'sub-visibility' bind 'v'
cycles through all the 'sub-visibility' choices, 'no', 'yes',
'primary-only', and 'secondary-only'.
Was tripping -Wparantheses as the && after the || was not explicitly
wrapped. However, due to operator precedence the intended effect was
still correct.
This commit is mainly for correcting the previous commit message.
The previous commit fixed an issue where [un]registering events above
the first event ID "hole" is not requested from libmpv, and that's
indeed true.
However, this had nearly zero impact in practice, because libmpv
enables all events by default anyway (except TICK).
Therefore, above the first ID "hole" [un]register requests are not
sent to libmpv, and the events just keep arriving.
But the callback functions are still added/removed correctly (at
defaults.js), and so the script is not called back even if unregister
did not actually happen with libmpv.
The only event which was affected is TICK - which is not enabled by
default as it's deprecated, and before the previous commit could not
be enabled.
So the fix is more a general correctness fix now that the IDs array
can have "holes", but with effctively no impact in practice.
Commit 63205981 removed some events but left all other event IDs at
their original values, which created "holes" at the events IDs array.
The JS backend for mp.register_event maps a name to an ID by scanning
all IDs and stopping when the name was found or a NULL name was
returned. Lua does the same except that it doesn't stop on NULL name.
Previously it was not possible to have a NULL name before the end of
the array, but now it is possible due to the enumeration holes.
Fix by skipping missing names, like lua does.
Not all deprecated symbols were removed. Only three events were removed for now
since these are not used internally.
This bumps the library version to 2.0.
Allow --keep-open=always to work with --loop-playlist, where
before this patch it would work only on the last playthrough of the
playlist. This patch allows it to work on all playthroughs.
Fixes#9470.
Previously OSD was always displayed on {ch,pl}_{next,prev} left-click,
and seekbar-hover-chapter was always enabled and with fixed format.
Now it can be controlled with:
- chapters_osd, playlist_osd: yes/no (only affects left-click).
- chapter_fmt: lua string.format template, or "no" to disable.
Fixes#4675
youtube-dl and yt-dlp both support --sub-langs and --srt-lang in
addition to --sub-lang for defining languages of subtitles. This hook
only checked for sub-lang in --ytdl-raw-options and inserted --all-subs
in its absence.
Nearly all the code base correctly references the data as constant. But
a couple of instances - fix those.
Signed-off-by: Emil Velikov <emil.l.velikov@gmail.com>
This seems to work on gcc, clang and mingw as-is, but I made it
conditional on __GNUC__ just in case, even though I can't figure out
which compilers we care about that don't export this define.
Also replace all instances of assert(0) in the code by MP_UNREACHABLE(),
which is a strict improvement.
The problem with the previous code - which used mp.get_user_path, is
that it returns a path even with --no-config, and even if the file
doesn't exist.
This is why we tested the "config" property, and also used
mp.utils.file_info to check that the file exists.
mp.find_config_file doesn't return a path with no-cofig and doesn't
return a path if the file doesn't exists. It's simpler and better.
Normally there was no issue, but when the code converted a deeply
nested table into an mpv node - it didn't ensure the stack has room.
Lua doesn't check stack overflow when invoking lua_push* functions,
and leaves this responsibility to the (c) user via lua_checkstack.
Normally that's not an issue because when a lua (or autofree) function
is called, it's guaranteed at least LUA_MINSTACK (20) pushes.
However, pushnode and makenode are recursive, and each iteration can
add few values at the stack (which are popped when the recursion
unwinds), so checkstack must be used on (recursive) entry.
pushnode already checked the stack, makenode did not.
This commit checks the stack at makenode as well. The value of 6
(stack places to reserve) is with some room to spare, and in pratice
each iteration needs 2-3 at most (pushnode also leaves room).
Example which could previously corrupt the stack:
utils.format_json({d1={d2={<8 more times>}}}
This uses makenode to convert the lua table into an mpv node which
the json writer uses as input, and if the depth is 10 or more then
corruption could occur. mp.command_native is also affected, as well as
any other mp/utils command which takes a lua table as input.
While at it, fix the error string which pushnode used (luaL_checkstack
uses the provided string with "Stack overflow (%s)", so the user
message only needs to be additional info).
The speedup is due to moving big part of the autofree runtime overhead
(new lua c closure) to happen once on init at af_pushcclosure, instead
of on every call. This also allows supporting upvalues trivially, even
if mpv doesn't use it currently, and is more consistent with lua APIs.
While x2 infrastructure speedup is meaningful - and similar between
lua 5.1/5.2/jit, in practice it's a much smaller improvement because
the autofree overhead is typically small compared to the "real" work
(the actual functionality, and talloc+free which is needed anyway).
So with this commit, fast functions improve more in percentage.
E.g. utils.parse_json("0") is relatively fast and is now about 25%
faster, while a slower call like mp.command_native("ignore") is now
about 10% faster than before. If we had mp.noop() which does nothing
(but still "needs" alloc/free) - it would now be about 50% faster.
Overall, it's a mild performance improvements, the API is now more
consistent with lua, and without increasing code size or complexity.
mpv doesn't have other dot files in its config dir, and it also
shouldn't be "invisible".
The new name ~~/init.js now replaces ~~/.init.js
While mpv usually deprecates things before outright removing them,
in this case the old (dot) name is replaced without deprecation:
- It's a bad idea to execute hidden scripts, even if at a config dir,
and we don't want to do that for the next release cycle too.
- We warn if the old (dot) name exists and the new name doesn't,
which should be reasonably visible for affected users.
- It's likely niche enough to not cause too much pain.
If for some reason both names are needed, e.g. when using also an old
mpv versions, then the old name could be symlinked to the new one, or
simply have one line: `require("~~/init")` to load the new name, while
a new mpv version will load (only) the new name without warning.
This behavior is more convenient and allows profile conditions like:
[video]
profile-cond=get('current-tracks/video/image') == false
[image]
profile-cond=get('current-tracks/video/image')
Otherwise, these profiles have to be manually applied and restored in a
script.
The note about discouraging the use of current-tracks in scripts is
removed, because it makes people avoid using this convenient property.
It was added in 720bcd79d0 without leaving an explanation of why you
shouldn't use it, and the only reason seems to be that it doesn't work
with lavfi-complex, but this commit changes that.
This exposes whether a video track is detected as an image, which is
useful for profile conditions, property expansion and lavfi-complex.
The lavf demuxer sets image to true when the existing check detects an
image.
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.
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".
The custom init script should be considered a configuration file, and
as such it should be ignored when the user wants vanilla mpv - and now
it is ignored with --no-config.
Before this commit, animation-end was handled at render(), however,
it's not called on idle, which resulted in state.anitype ~= nil, with
nothing to reset it during idle, which caused in an infinite tick()
loop (starts on first mouse move).
Now tick resets the animation on idle, and also, as a safety measure,
if we're past 1s after the animation deadline.
The safety measure is because the osc states are complex, and it's
easier to detect a "we really shouldn't be animating now" at tick()
itself rather than detecting the exact states where animation should
be reset. Generally, the safety mmeasure is not needed.
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".
Previously, loading ~~/.init.js was inside a try block, in order to
quietly ignore errors if the file doesn't exist.
However, that also prevented any real errors from showing up even when
the file does exist, and the script continued as if everything is OK,
while in fact the custom init script didn't complete correctly.
Now we first check if the file exists, and then load it without
try/catch, so that any error shows up normally (and abort the script).
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.
When changing video track with subtitles with unknown duration, they
aren't shown until you seek, cycle sub back and forth, or apply a video
filter. This is caused by reinit_video_chain_src() calling
reset_subtitle_state() -> sub/sd_ass.c:reset() -> ass_flush_events()
when ctx->duration_unknown is true.
The ass_flush_events() call was added in a714f8e so subs with unknown
duration wouldn't multiply on seek, i.e. when reset_subtitle_state() is
called from reset_playback_state(). So keep calling it from there, and
in reinit_video_chain_src() use just term_osd_set_subs(mpctx, NULL)
instead to clear any subtitles printed to the terminal. The
reset_subtitle_state() call was added in c1ac97b to "reset the state
correctly when switching between video/no-video", but with it removed I
no longer notice any issue doing that.
29e15e6248 prefixed youtube-dl's subs url with an edl prefix to not
download them until they're selected, which is useful when there are
many sub languages. But this prefix broke the alignment of secondary
subs, which would overlap the primary subs instead of always being
placed at the top. This can be tested with
--sub-file='edl://!no_clip;!delay_open,media_type=sub;secondary_sub.srt'
When a sub is added, sub.c:reinit_sub() is called. This calls in
init_subdec() -> dec_sub.c:sub_create() -> init_decoder() ->
sd_ass:init(). Then reinit_sub() calls
sub_control(track->d_sub, SD_CTRL_SET_TOP, &(bool){!!order}) which sets
sd_ass_priv.on_top = true for secondary subs.
But for EDL subs the real sub is initialized again when in
dec_sub.c:sub_read_packets() is_new_segment() returns true and
update_segment() is called, or when sub_get_bitmaps() calls
update_segment(). update_segment() then calls init_decoder(), which
calls sd_ass:init(), so sd_ass_priv is reinitialized, and its on_top
property is left false. This commit sets it to true again.
For URLs that need to be downloaded it seems that the update_segment()
call that reinitializes sd_ass_priv is always the one in
sub_read_packets(), but with local subs sub_get_bitmaps() is usually
called earlier (though there shouldn't be a reason to use the EDL URL
for local subs), so I added the order parameter to sub_create(), rather
than adding it to all of update_segment(), sub_read_packets() and
sub_get_bitmaps().
Also removes the cast to bool in the other sub_control call, since
sub/sd_ass.c:control already casts arg to bool when cmd is
SD_CTRL_SET_TOP.
When performing the scaling calculations, the window scale properties do
not bother checking for potential monitor par. The vo keeps track of
this via vo->monitor_par. Simply multiply/divide the video's width or
height depending on the value of monitor_par. We also clamp the values
to avoid the values running away to infinity in extreme cases.
The vo currently handles rotations in 90 degree steps and some VOs set
this via VO_CAP_ROTATE90. When the rotation exactly hits either 90 or
270 degrees, this causes the values of dwidth and dheight to perfectly
swap like one would expect. However, the mp_image_params_get_dsize
function call in both of the window scale functions do not take this
special case into account. So the width/height values returned will be
incorrectly flipped in the 90 and 270 degree cases if the vo driver does
implement VO_CAP_ROTATE90 (like vo=gpu). Fortunately, the
mp_image_params struct keeps track of the rotation for us. So all we
need to do is check if the image is rotated at 90 or 270 degrees and
check that the current vo driver supports VO_CAP_ROTATE90. If so, then
swap vid_w and vid_h to their true, correct values.
Based on a small patch originally written by @avih. Instead of
duplicating the window-scale logic in update_window_scale, just call the
mp_property_current_window_scale function with the M_PROPERTY_SET action
and a NULL property.
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.
Previously we assumed the key-name string occupies strlen(name) cells,
now we count codepoints instead.
This improves alignment of non-english key names. Still not perfect
because we don't know if the key name is single or double width, but
wcwidth not available to scripts, notoriously unreliable (depends on
locale, correct and updated tables, etc), and also not always
available (Windows).
Still, better than nothing, and we err by at most one cell - vs up to
three before this commit (4 bytes keyname codepoint).
In the future we could do the alignment using libass tags, however,
this both complicates the ass-output generation, and also not available
when we output for the terminal, so for now only count codepoints.
Also, if the key name was in a right-to-left language, then previously
the name/command were swapped visually. Now we inject a left-to-right
marker before the name to ensure direction. This works also when
harfbuzz is disabled for libass (--sub-ass-shaper=simple).
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.
When changing image-display-duration at runtime, make the new value take
effect immediately, rather than from the next playlist-position change.
This allows toggling the slideshow mode while viewing images (without
hacks like executing playlist-play-index current afterwards).
All the conditions are just to be safe since even if you set time_frame
while playing a video, it's immediately overwritten by the next value.
mpv has two methods to display output from text input:
- show-text (scripting: mp.osd_message) has ass disabled by default
(escaped), and the property osd-ass-cc can control escaping.
- osd-overlay (scripting: mp.set_osd_ass or mp.create_osd_overlay)
has ass enabled (unescaped), and osd-ass-cc is NOT supported.
By default, stats.lua uses mp.osd_message which does support escaping.
That's persistent_overlay=no.
When using persistent_overlay=yes then mp.set_osd_ass is used.
Due to this, the no_ASS(..) function - which is supposed to escape
ass, simply returned its input unmodified when persistent_overlay
is enabled.
This is not a new issue, and the filters on page 1 use no_ASS() to no
avail in persistent mode, however, this content (filter name and value
strings) rarely actually needs escaping, and users didn't notice.
However, the new page 4 (keys) does break visibly when no_ASS doesn't
work, because it tries to escape arbitrary key-names and command
strings, and at the very least the key '{' is bound by default, which
is displayed incorrectly if escaping doesn't work.
Fix this by rolling our own escaping when using mp.set_osd_ass,
similar to how the mpv code does it for mp.osd_message (substrings
replacements).
However, this means that the set_ASS(..) function can no longer
behave correctly because escaping requires going through the whole
content string rather than only inserting a marker.
Luckily, other than at no_ASS, set_ASS was only used at one place
(text_style), which is only called from two places:
- generate_graph() only needs to restore styles - not to enable ass.
- add_header() is only used at the begining of page output, and
uses set_ASS to enable ass initially when using mp.osd_message.
So remove the set_ASS function, and instead enable ass directly at
print_page using osd-ass-cc when mp.osd_message is used.
Fixes#9022
As it turns out, js_try can throw if it runs out of try-stack
(without/before entering either the try part or the catch part).
If it happens, then C code which does allocation -> try will leak.
In mpv there were two places which do alloc and then try, one of
them as part of the autofree system. On both cases the leak is the
smallest possible (zero allocation) - talloc_new(NULL);
It's very unlikely to trigger - an autofree mpv API should be called
when the try-stack is exactly full, and our next try will throw
(and guaranteed to get caught at an outer level, but with a leak).
Fix that by doing the allocation inside the try block, so that if
try throws before it's entered then nothing got allocated/leaked.
Mujs internal code also has/had similar leaks, which are getting
fixed around this time (July 2021, post mujs 1.1.3).
[1] exhaust the try-stack or call-stack, whichever comes first:
function kaboom() { try { kaboom() } catch(e) {} }
Previously, if a script bound the same key more than once to different
functions (without removing the older bindings first), then pressing
the key triggered any of the bound functions arbitrarily[1].
Now the newest binding for the same key is always the active one.
If the newest binding is then removed - the second-newest will become
active, etc. (same mechanism as before, except that the active key
was not always the newest).
[1] The order was implementation-defined, however `for (name in obj)'
happens to iterate. With mujs that's currently alhabetic order,
and name is from mp.add_[forced_]key_binding(key, name...)
or generated internally if name is not provided. So a binding with
higher alphabetic `name' value had priority over lower name value.
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.
Page 4 bindings listing wants to exclude the interactive keys of the
stats script itself - so that they don't hide the normal keys which
are bound when stats is not interactive.
It did so by testing that the bound command includes stats/__key
which is how it usually looks when a script binds keys.
However, if a script uses a name for the binding - like stats.lua does
for the interative keys (because it later removes them by name when
interactive mode ends), then the command has stats/name rather than
stats/__key...
To fix this, we change the names of the forced interactive bindings
to start with __forced_, and that's now also what the page-4 listing
excludes.
This reverts commit 0f1654811bda0dfdd337734ec33c59b67522234a.
It was an incorrect fix, because the key names do get used - to remove
the forced bindings once stats exits the interactive mode.
And without names - the interactive keys remained active even after
stats exited interactive mode.
The page 4 keybinding list tries to skip the interactive bindings of
stats itself (because they would hide the normal bindings of these
keys when stats is not visible), and to do that it excludes commands
containing "script-binding stats/__key" - which is how script-added
bindings usually look like.
However, keys which are added with a "name" bind stats/name rather
than stats/__key... - and that's what stats.lua did till now with its
interactive force-bindings.
Now the interactive forced bindings are added without a name, and so
they do end up using the automatic stats/__key... and get excluded.
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.
Typically the current page is rebuilt and rendered once per second,
howeve, scrolling can invoke the rebuild function very frequently,
even at a rate which is too fast for the rebuild function to keep
up. This can result in high CPU usage and input lag.
This commit adds an argument to the page-rebuild function, letting it
know whether or not it's called following a scroll keypress, thus
allowing it to cache intermediate data so that it doesn't have to
re-calculate the whole page from scratch.
This additional argument is unused currently, but it could be useful
for the internal performance page - which can be relatively heavy.
When playing a new file, if paused_for_cache was true before being reset
the AO would never be unpaused because that state was thrown away, leaving it stuck.
Fix this by updating the pause state before resetting that variable. Note that this
does not make the second update_internal_pause_state() call redundant.
This fixes the same bug fb5d976cb0 was supposed to.
reinit_audio_filters_and_output function will free mpctx->ao_chain
when there is a failure during audio initialization. So modify it
to return -1 in case of init failure. The return value is checked
to avoid use after free. Reported by Address Sanitizer when manually
specifying --ao which triggers "Failed to initialize audio driver" error.
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'.
Though, only when the output format is matroska, to avoid muxing errors.
This is quite useful when the input has ASS subtitles, as they tend to
rely on embedded fonts.
osc-visibility can already be changed at runtime via script-message
or other means, but until now there was no way to tell what the
current state is.
Now shared-script-properties/osc-visibility reflects this state.
It's output-only by the osc - changing it does not affect the osc.
Useful if a script wants to change osc-visibility temporarily, and
later restore to its original state.
There's no way to coordinate if more than one script wants to change
it, but that would be a hard problem to solve anyway, even if the
osc itself tried to coordinate such requests from different sources.
Commits 4d1ffec and 6e481d0 renamed sub-ass-style-override to
sub-ass-override. But in commit bd603c2, when renaming it in
quit-watch-later's backup_properties, which determines which properties
are saved by quit-watch-later/write-watch-later-config, it was
incorrectly renamed to sub-style-override instead, and thus never got
saved even if modified at runtime. Instead mpv attempted to save the
non-existing property "sub-style-override", but since no error is raised
when saving non-existing properties with quit-watch-later, no one
noticed it. This commit renames the saved property to the correct new
name "sub-ass-override" so that it does get saved.
This fixes two issues, both of which resulted from the timers-wait
period not being re-calculated after idle-observers were executed:
- If timers were added from an idle observer then they could fire long
after they were due (only when/if the next mpv event arrives).
- Idle observers don't execute in zero time, and the wait period for
the next timer was implicitly extended by the idle observers
execution time (because it was calculated before the idle observers).
This commit ensures that if idle-observers were executed, then the
timers wait period is re-calculated, which solves both issues.
Previously, process_timers() kept going as long as there were due
timers, which could be for extended periods of time or even forever
if there were slow timer callbacks with either periodic timers or if
timers were added repeatedly.
This prevented dequeuing mpv events, and subsequently, among others,
prevented mpv from quitting until process_timers() completed.
For instance, this caused process_timers() to never return:
function render() <longer than 1/60 s on a slow system> end
mp.add_periodic_timer(1/60, render)
Similarly, it never returned if a timer callback always added a new
one-shot which was already due by the time the callback completed.
This commit ensures that process_timers() only executes callbacks which
were due when it started, so that timers which are added (or repeated)
during process_timers() will wait for the next iteration - after mpv
events are dequeued.
This has no performance impact under normal conditions (when callbacks
complete before the next timer is due).
Additionally, previously idle-observers were executed unconditionally
after the timers because indeed there was nothing due when (if...)
process_timers() completed. However, now process_timers() can return
even if there are due timers, so skip idle-observers on such case.
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.
The idle-observers block has at least 3 function calls, and it was
entered every time the script went into idle, however, we can save these
calls by checking first that there are indeed such observers.
Remove the check that the external filename is not the same as the
currently playing one, which prevents mpv from loading images again as
external cover art, but this isn't necessary because cover art is only
added when playing standalone audio. I had only added this check because
I would otherwise get a segfault only when compiling with gcc 10.2 with
optimize and changing position within a playlist of multiple images (and
this couldn't even be reproduced by Dudemanguy on the same gcc version),
but this was caused by the uninitialized lang variable which is now
fixed.
Commit 029ff10 added a goto statement which skipped initializing the
`lang' variable. This could crash depending on compiler optimizations
and other factors: if the lang bstr pointer happened to end up NULL
(which is apparently the case with most compilers) then it's validly
empty, but if it pointed to a random and incorrect memory address then
it crashed.
The crash was observed when mpv was compiled using gcc 10.2 with
optimizations enabled, and affected some third party Windows builds.
This commit ensures the goto doesn't skip the initialization.
Thanks to votemp for figuring this out.
Fixes#8922.
Previously tick() was ensured unconditionally only after mouse-move,
but there are other mouse-events which need re-rendering (tick), like
mouse-down (icons may get grayed-out) or mouse-up (icons may change).
For instance: mpv --pause --myclip.mkv
then move the mouse over the volume/mute OSC button, then - without
moving the mouse - press and release the left mouse button.
The osc was not re-rendered because it's paused and the mouse didn't
move, so the volume icon didn't get grayed-out when held down, and the
icon doesn't change on mouse-up (to reflect the new mute state).
Now both these changes are rendered correctly.
This is not a new issue, however, until the last commit - 96b246d
init probably didn't happen much (or at all) between mouse-down and
mouse-up, but after this commit, if there are chapters in a live-stream
then osc_init() is used to re-render the markers at the adjusted
position - which breaks the OSC buttons functionality if init happened
between mouse-down and mouse-up.
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 moves the JSON parsing above the main youtube-dl error-handling
block and integrates parsing errors into that block. Now, if a parsing
error occurs, youtube-dl's stderr will be logged as it is with other
errors. This also catches errors that cause youtube-dl to output
"null", which would previously be mishandled as a parsing error and
crash ytdl_hook when it attempted to concatenate the error string from
parse_json.
When the OSC initializes, it checks whether the current video has
chapters, and if it does not, it disables its chapter functionality
(chapter buttons are grayed out and unusable, chapter indicators don't
show on the seek bar). If another script changed the chapter list
after the video has loaded, those changes would be ignored by the OSC
until some other event causes it to re-initialize, because it did not
observe the chapter list property. This is fixed by adding
observation of chapter-list alongside the other properties that
trigger re-initialization.
Shows uploader, channel, description fields. This works only if the
media media is constructed as EDL (for youtube it usually does this),
and if the all_formats option is not set to true (does anyone even use
it?). The former usually happens because youtube serves audio and video
separately, though it will not for live HLS/DASH. The latter uses
delayed media opening, which breaks the global_tags mechanism (see
previous commit).
