Regression from 24357cb. It's ugly but unfortunately keeping tracking of
the last toplevel width and height really is the best way to solve this
problem and removing it was a mistake. Compositors don't always send
width/height coordinates of the actual window. The easiest way to
trigger this is by changing window-scale/current-window-scale and then
unfocusing the window. The compositor will send another toplevel
configure event with coordinates of the window before the resize. Maybe
compositors could be smarter but multiple ones do this (sway, gnome,
plasma), so just keep the old workaround. The only difference this time
is that the toplevel width/height is saved at the very beginning which
also covers the case where it equals 0 (i.e. weston).
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.
1. On a pathological case where event_format is NULL, previously the
filter was trying to use it with each new sub - and re-failed. Now
the filter gets disabled on init (event_format doesn't change).
2. Previously, if the filter didn't modify the text or if the text
could not be extracted - it still allocated a new packet with same
content. Now it returns the original, saving a whole lot of no-ops
(there are still few allocations in this case though).
1 above is preparation for the next commit, and 2 was trivial, but
there's more to do if anyone cares (NIH string functions instead of
bstr, unused arguments, messages could be improved, and more).
Add two stand-alone function to help with the text-extraction task
which ass filters need. Makes it easier to add new filters without
cargo-culting this functionality.
Currently, on malformed event (which shouldn't happen), a warning is
printed when a filter tries to extract the text, so if few filters
are enabled, we'll get multiple warnings (like before) - not critical.
The regex filter now uses these utils, the SDH filter not yet.
The source of many geometry woes. There's some loosely related toplevel
things that should be cleaned up/fixed. First of all,
VO_EVENT_LIVE_RESIZING is actually completely useless. It might have
been useful sometime in the past, but there's no point. It doesn't
"speed up" resizing in any way and appears to be originally for cocoa.
Just remove it.
Way back in the day, toplevel_width/height was added as a workaround for
when we got uncoorperative (i.e. wrong) width/height coordinates from
the compositor in this event. Basically it could happen due to numerous
reasons but a lack of atomic commits was part of the reason and also
mpv's geometry handling then was a lot rougher. We *shouldn't* need this
workaround anymore. The width/height values are only used exactly when
we need them. If mpv sets geometry on its own, it should still be the
right dimensions.
Related to the above, mpv never actually propertly handled the case
where width or height was equal to 0. According to the xdg-shell spec,
"If the width or height arguments are zero, it means the client should
decided its own window dimension." An example of a compositor doing this
is weston. It's, unsurprisingly, broken. Getting out of fullscreen or a
maximized state does not restore the old window size like it should. The
right way to handle this is to just return near the end of the function
if we have a 0 for either argument and before any geometry is set
(wl->geometry's width or height can never be zero). Luckily, state
changes are already being detected so they just trigger the goto when
needed.
Finally, e2c24ad mistakenly removed the VO_EVENT_EXPOSE. There are edge
cases where this is needed and it's safer to just force a redraw here
when the window gets activated again. Just force wl->hidden to false
first and then trigger the expose.
Since 1d1d1fbff9 option-info/<name>/set-locally was being set to true
for every option. This broke setting start from ytdl-hook, which doesn't
overwrite start if it was set-locally. Fix this so that only adding an
option to reset-on-next-file or setting file-local-options/<name> make
set-locally true like before.
However, it's arguable that just adding an option to
reset-on-next-file without ever changing it should not make set-locally
true, so that e.g.
--reset-on-next-file=start 'https://youtube.com/watch?v=...&t=30'
will start at 30, though it currently doesn't.
Fixes#9081.
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).
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.
Because having these on every video is annoying, and when you resume
from watch later files, the filters are applied immediately so they hide
your osd-playing-msg or equivalent show-text commands.
More wayland weirdness. So previously, flipping a hidden state from true
to false was done in vo_wayland_wait_frame. In theory, this would be
after you get the frame callback and all those events so there's no
problem. However since the function also does a bunch of
flushing/dispatching/etc. to the default display queue so a lot of
unknown things can happen before we actually set the hidden variable
back to false. For example if a single image was paused and left on
another virtual desktop long enough (~5 minutes) while also not having
focus, switching back to that desktop could render it a black frame.
This edge case was supposed to be handled by the surface being activated
again in the toplevel event but apparently that doesn't always work. The
fix is to just delete all of that junk and set wl->hidden = false in the
frame callback. What's actually happening is kind of a mystery honestly.
Probably the compositor drops the buffers after a while as an
optimization (sensible) and forces a repaint if you switch back to the
virtual desktop. Somehow wl->hidden not being set to false would not
properly trigger a repaint (likely because it also sends a toplevel
event which does stuff) thus you just get a black window. If you just
make sure to set hidden in the frame callback, it appears like all of
these problems and edge cases are solved. Since this event must happen
first, that makes sense. That simplifies a lot of stuff and fixes some
subtle bugs at the same time so just go with this approach.
The EGL stuff is really complicated because of historical reasons
(tl;dr: blame EGL). There was one edge case with EGL context creation
that lead to incorrect behavior. EGL_KHR_create_context was created with
EGL 1.4 (which mpv does support) but it is still possible for an EGL 1.4
device to not implement this extension. That means that none of the EGL
attrs that pass a specific opengl version work. So for this obscure
case, there is a fallback context creation at the very end which simply
creates an EGLContext without passing any special attrs.
This has another problem however. mpv has a hard requirement on at least
desktop opengl 2.1 or opengl ES 2.0 to function (we're not asking for
much here). Since the fallback EGL context creation has no version
checking, it is entirely possible to create an EGL context with a
desktop opengl version under 2.1. As you get further along in the code,
the user will encounter the hard opengl version check and then error
out. However, we're supposed to also actually check if GLES works
(that's what the opengl-es=auto option is for) so this is a bug.
The fix is to do a bit of code duplication and make a mpgl_check_version
specifically for if we hit the edge case of needing to create an EGL
context without the EGL_KHR_create_context extension. Grab the version
with the function pointer, check if it's under 210, if so destroy the
EGL context and set it to NULL. After that, if the user has set
opengl-es to auto, mpv will try GLES next. If it is set to no, then mpv
will simply fail as desired. Fixes#5915.
Sidenote: the ra_gl_ctx_test_version originally testing 140 doesn't make
any sense. Passing the version number in that function only does
something if the user has set opengl-restrict. What we need to do is to
pass the version of the created context to that function. If the version
is higher than the opengl-restrict option, then make this a failure.
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
This was explictly coded to avoid the autoprobe way back when in
2015[1] with no real explanation. In theory, there shouldn't be any
issues allowing this. If a user runs mpv in tty, this is probably what
they actually want in most cases. Perhaps something strange happens on
nvidia, but it should just fail anyway during the autoprobe.

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) {} }
--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=
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.
- 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.
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.
