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
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.
Avoiding blindly copying the codec_tag between different formats allows
us to mux packets from, say, mpegts streams to matroska, making the
recorder (dump-cache) much more usable as unsupported codec_tags can
make the muxer reject the streams.
This brings my scaletempo2 benchmark down from ~22s to ~7s on my machine
(-march=native), and down to ~11s with a generic compile.
Guarded behind an appropriate #ifdef to avoid being ableist against
people who have the clinical need to run obscure platforms.

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.
Take two. f4e89dd went wrong by moving vo_wayland_wait_frame before
start_frame was called. Whether or not this matters depends on the
compositor, but some weird things can happen. Basically, it's a
scheduling issue. vo_wayland_wait_frame queues all events and sends them
to the server to process (with no blocking if presentation time is
available). If mpv changes state while rendering (and this function is
called before every frame is drawn), then that event also gets
dispatched and sent to the compositor. This, in some cases, can cause
some funny behavior because the next frame gets attached to the surface
while the old buffer is getting released. It's safer to call this
function after the swap already happens and well before mpv calls its
next draw. There's no weird scheduling of events, and the compositor log
is more normal.
The second part of this is to fix some stuttering issues. This is mostly
just conjecture, but probably what was happening was this thing called
"composition". The easiest way to see this is to play a video on the
default audio sync mode (probably easiest to see on a typical 23.976
video). Have that in a window and float it over firefox (floating
windows are bloat on a tiling wm anyway). Then in firefox, do some short
bursts of smooth scrolling (likely uses egl). Some stutter in video
rendering could be observed, particularly in panning shots.
Compositors are supposed to prevent tearing so what likely was happening
was that the compositor was simply holding the buffer a wee bit longer
to make sure it happened in sync with the smooth scrolling. Because the
mpv code waits precisely on presentation time, the loop would timeout on
occasion instead of receiving the frame callback. This would then lead
to a skipped frame when rendering and thus causing stuttering.
The fix is simple: just only count consecutive timeouts as not receiving
frame callback. If a compositor holds the mpv buffer slightly longer to
avoid tearing, then we will definitely receive frame callback on the
next round of the render loop. This logic also appears to be sound for
plasma (funfact: Plasma always returns frame callback even when the
window is hidden. Not sure what's up with that, but luckily it doesn't
matter to us.), so get rid of the goofy 1/vblank_time thing and just
keep it a simple > 1 check.
Checking against 1.0 is wrong for this code, because it's in an absolute
luminance scale relative to reference white. We should be normalizing
this by `dst.sig_peak`.
This is actually a very nice simplification that should have been
thought of years ago (sue me). In a nutshell, the story with the
wayland code is that the frame callback and swap buffer behavior doesn't
fit very well with mpv's rendering loop. It's been refactored/changed
quite a few times over the years and works well enough but things could
be better. The current iteration works with an external swapchain to
check if we have frame callback before deciding whether or not to
render. This logic was implemented in both egl and vulkan.
This does have its warts however. There's some hidden state detection
logic which works but is kind of ugly. Since wayland doesn't allow
clients to know if they are actually visible (questionable but
whatever), you can just reasonably assume that if a bunch of callbacks
are missed in a row, you're probably not visible. That's fine, but it is
indeed less than ideal since the threshold is basically entirely
arbitrary and mpv does do a few wasteful renders before it decides that
the window is actually hidden.
The biggest urk in the vo_wayland_wait_frame is the use of
wl_display_roundtrip. Wayland developers would probably be offended by
the way mpv abuses that function, but essentially it was a way to have
semi-blocking behavior needed for display-resample to work. Since the
swap interval must be 0 on wayland (otherwise it will block the entire
player's rendering loop), we need some other way to wait on vsync. The
idea here was to dispatch and poll a bunch of wayland events, wait (with
a timeout) until we get frame callback, and then wait for the compositor
to process it. That pretty much perfectly waits on vsync and lets us
keep all the good timings and all that jazz that we want for mpv. The
problem is that wl_display_roundtrip is conceptually a bad function. It
can internally call wl_display_dispatch which in certain instances,
empty event queue, will block forever. Now strictly speaking, this
probably will never, ever happen (once I was able to to trigger it by
hardcoding an error into a compositor), but ideally
vo_wayland_wait_frame should never infinitely block and stall the
player. Unfortunately, removing that function always lead to problems
with timings and unsteady vsync intervals so it survived many refactors.
Until now, of course. In wayland, the ideal is to never do wasteful
rendering (i.e. don't render if the window isn't visible). Instead of
wrestling around with hidden states and possible missed vblanks, let's
rearrange the wayland rendering logic so we only ever draw a frame when
the frame callback is returned to use (within a reasonable timeout to
avoid blocking forever).
This slight rearrangement of the wait allows for several simplifications
to be made. Namely, wl_display_roundtrip stops being needed. Instead, we
can rely entirely on totally nonblocking calls (dispatch_pending, flush,
and so on). We still need to poll the fd here to actually get the frame
callback event from the compositor, but there's no longer any reason to
do extra waiting. As soon as we get the callback, we immediately draw.
This works quite well and has stable vsync (display-resample and audio).
Additionally, all of the logic about hidden states is no longer needed.
If vo_wayland_wait_frame times out, it's okay to assume immediately that
the window is not visible and skip rendering.
Unfortunately, there's one limitation on this new approach. It will only
work correctly if the compositor implements presentation time. That
means a reduced version of the old way still has to be carried around in
vo_wayland_wait_frame. So if the compositor has no presentation time,
then we are forced to use wl_display_roundtrip and juggle some funny
assumptions about whether or not the window is hidden or not. Plasma is
the only real notable compositor without presentation time at this stage
so perhaps this "legacy" mechanism could be removed in the future.
when using the bundle with activated big enough cache, very slow and
wasteful memory allocations lead to jittery playback and lot of dropped
frames. the cache had to have a certain size so it would constantly
allocate new memory to reproduce this. this never happens when started
from the terminal.
the source of the problem is a different malloc allocation policy,
MALLOC_NANO, that allocated a huge amount of virtual memory without
actually using it. the usage was between 0% to 25% of that virtual
memory. the binaries allocation policy on the other hand used >80% of
that allocated virtual memory and was a lot more efficient, it would use
MALLOC_TINY instead.
this is fixed by setting the MallocNanoZone environment variable to 0
to use the V1 of the allocation policy. when started from the bundle via
launchd this is forced to 1 and V2 policy which causes this problem.

this can cause stutter on remote files because in certain cases this
causes a reconnect to the remote that leads to the file not being read
fast enough. VLC had the same problem and fixes it the same way.

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).
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.
When trying to use completion for mpv binaries specified with some shell
glob, e.g. ~/dev/mpv/build/mpv, the current code doesn't substitute the
homedir prefix into the path name, resulting in runtime errors about
the file '~/dev/mpv/build/mpv' not being found.
The simple fixed is to use $~var instead of $var whenever expanding the
filename, which performs the same globbing that would otherwise be
performed when executing the command.
This reverts commit b8156a9a86.
Apparently there are two problems here. One on Linux (fixed by the
original change and this revert) and one on alternative-medicine-Job's
OS. Since the latter has deprecated OpenGL and OpenGL is a second-class
citizen, I think it's better to prefer the fix for a platform that is
still alive.
When inserting vf_sub, the VO OSD is directed not to draw itself. But
this flag was never unset, even when removing vf_sub.
The fix is pretty shit, but appears to work.
Switching to a new file while keeping the AO didn't update the volume.
While there's an explicit audio_update_volume() call in
reinit_audio_chain_src(), it doesn't work, because at that point
ao_chain->ao is still NULL, and it does nothing. That's pretty weird and
might cause other problems (what happens if you try to mute while the AO
is "floating"?). Regarding gapless, trying to use the AO gain for
replaygain is also gross nonsense, because the new replaygain computed
gain would affect audio from the previous file. It looks like replaygain
should be in an af_volume filter maybe. On the other hand, I enjoy
setting ridiculous replaygain-preamp values and compensating with a low
volume setting, which would not work well if both gains were applied to
the audio independently.
For now, just add the missing call. This is orthogonal to fixing
replaygain "properly".
This reverts commit 3239e41277.
I'm fairly sure this is wrong, and my next commit should fix it
properly. I'm not really sure, though. Normally, the AO is set again
by reinit_audio_filters_and_output() after the new audio chain has
decoded a frame and knows the new format. The reason replaygain (and
apparently the thing the reverted commit tried to fix) didn't work is
because they work asynchronously to the audio played by the AO (i.e.
buggy and hard to fix).
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.

3909e4cdfc seems to have replaced this 0.5 constant by 0.75, using its
presence in glumpy as justification.
0.75 is clearly a bug in glumpy, as its own source code doesn't even
match the comment immediately above it. Every other implementation of
this window I could find uses 0.5, including e.g. ImageMagick.
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
We now have at least 3 scripting APIs which are trivial wrappers
around properties: mp.get_mouse_pos, utils.getcwd, utils.getpid.
After some discussion on IRC it was decided that it's easier for us to
maintain them as trivial wrappers than to deprecate them and inflict
pain on users and script authors, so currently no plan to deprecate.
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.
This fixes a bug where using boxvideo with showfullscreen=no or
showwindowed=no resulted in the margins not resetting when the OSC
wasn't visible.
For example, using:
script-opts=osc-visibility=always,osc-boxvideo=yes,osc-showfullscreen=no
and then going fullscreen would make the OSC disappear but the video
margins would remain. This is because boxvideo was missing a dependence
on the showfullscreen and showwindowed user options.
This is fixed by adding the corresponding conditions to update_margins()
and setting state.marginsREQ on fullscreen changes. update_margins() is
called on tick() if there's a margins update pending, which guarantees
the boxvideo margins are reset appropriately.
It turns out that if a user specifies fullscreen=yes and a width/height
in an autoprofile, the compositor can execute its toplevel listener
event. This can happen before we have any mpv window rendered at all so
we end up performing a bunch of geometry operations and state checks
when we shouldn't. It subtly messes up a lot of things like state
detection. Just return from this function if the geometry has no width
or height yet.
Clearing state.osd.data with an empty string at render_wipe() fixes an
issue where changing the OSC visibility from "never" directly to
"always" didn't immediately update the display when the player was
paused. This could be verified by starting the player with
`--script-opts=osc-visibility=always --pause` and then running
`script-message osc-visibility never` followed by
`script-message osc-visibility always`.
Removing the overlay without changing the contents meant the overlay
wouldn't update and display when enabled again until the fields changed
in some way (e.g. seeking, mousing over the OSC area, etc.). Clearing
state.osd.data before removal of the OSC makes sure set_osd doesn't
return on re-enable and instead displays the OSC immediately as the data
is now different.
render_wipe() is now also used when the OSC needs to be cleared at
tick() as using set_osd to clear it with an empty string did not call
state.osd:remove() which can allow cleanups related to bitmap memory
allocations etc.
this is a regression of af26402, where we changed the geometry
calculation to use the visible frame and consider its origin. though the
origin is not screen relative but relative to the main screen. the rest
of the code expects a screen relative rectangle. because of that windows
would be placed out of the screen bounds when not on the main screen.
recalculate to origin to be screen relative and use those values for the
rest of the calculations. to make the code a bit more comprehensible
be a bit more explicit about what is done where with temporary variables
and comments. also move the mp_rect calculation that moves the origin
and flips the y position to a separate function, so we can reuse it
later.
The fit_on_screen logic was a bit twisted. Simplify it a bit
and update few comments to explain better what it's used for.
Note that the new logic is not identical to before, but its intent
should now be clearer. This means there might be regressions or
improvements at edge cases. If followup fixes are needed, then we
should keep the intent clear. Most likely though that it's fine.
fit_on_screen is called only from reinit_window_state.
Move the yes/no logic unmodified from fit_on_screen to
reinit_window_state, and remove the w32->parent condition because it's
already checked earlier at reinit_window_state.
Previously, because the video (client area) was centered but the top
and bottom borders are uneven (title is taller), then if the window
is shrunk vertically to just-fit the desktop - the top edge of the
title bar ended above the top edge of the display.
This is a state which Windows prevents during manual move, but
apparently it's not rejected at the Windows API.
Now we ensure it doesn't happen, and nudge the window down to align
the top edges if necessary.
This is a commulative regression of commits 981048e0 and 364af7c6.
To clarify functionality, this includes a no-op change: fit_rect was
renamed to fit_rect_size and it now takes explicit width and height,
because it only used the width/height of rc2 anyway.
