We wanted to preserve the libplacebo v5.264.0 requirement for gpu_next
for this release, since this is the what most Linux distributions are shipping.
The VLC 3 <-> libplacebo v6 situation is an additional reason distros are not
likely to ship the newest libplacebo release soon.
This reverts commit b73d96776c.
Doing a pw_thread_loop_wait() without checking conditions is invalid.
The thread loop could be signalled for other reasons and in this case
the wait needs to continue.
PipeWire added such additional signaling in
commit 33be898130f0 ("thread-loop: signal when started").
This meant that for_each_sink would return before the callbacks have
fired and session_has_sink() would incorrectly return "false", failing
the initialization of ao_pipewire.

Make it clearer that you should be using --hwdec with this VO. Also make
some comments about the things that are required for this to work
correctly (i.e. working drivers/GPU and the right compositor).
Since this works by mpctx giving us a dummy image, we can be reasonably
be confident that when we receive a matching imgfmt with no underlying
hw_subfmt that this is simply force window from the player. Just allow
this to go through the usual wayland logic and skip the hwdec checking.
When we get the real image later, it will still error out on the
compositors that don't have proper support.
It's a bit of an edge case, but since we now allow the disabling of the
software fallback it's possible to have a situation where hwdec
completely fails and the mpv window is still lingering from the previous
item in the playlist. What needs to happen is simply that the vo_chain
should uninit itself and handle force_window if needed. In order to do
that, a new VDCTRL is added that checks vd_lavc if force_eof was set.
player/video will then start the uninit process if needed after getting
this.
There's an option that's supposed to stop mpv from falling back to
software decoding if hardware decoding fails. Except that it doesn't
work and can fallback to software decoding anyway. Correct this by
checking if all possible hwdec failed after the loop in
select_and_set_hwdec and that we have this option. If so, flag a bool to
force eof. In decode_frame afterwards, we then simply immediately return
an EOF.
When video width is not a multiple of slice size, the last slice will overflow. Fix this by adjusting the width of the last slice to fit within the video.
Fixes issue #10436
Currently, the osc will add a margin of (osc_height / 2) to the
deadzonesize for the window controls, the topbar and the bottombar,
i.e. when osc-deadzonesize=1, the osc will show up even if the cursor
is only hovering (osc_height / 2) pixels above or below it. This is not
what this option is supposed to do according to the manual, instead
osc-deadzonesize=1 should result in the osc only appearing when it is
directly hovered. The user can simply set osc-deadzonesize=0.9 or so if
such a margin is desired, instead make the option work as advertised by
removing this margin.
It should be noted that osc-layout=box does not share this behavior,
and it already works as advertised in the manual.
mpv already has a bunch of software scaling utils. Instead of forcing
every VO to implement this, we can just grab the frame and scale it in
software in one central place. Fixes#11968.
We should always be trying hardware screenshots (VOCTRL_SCREENSHOT and
VOCTRL_SCREENSHOT_WIN) before software ones. Rearrange all the logic
here to hopefully make this clearer. The mode is passed to add_osd
(renamed since it will also be used to add the osd) which will be used
more in the next commit.
Reading the config when we're just interested in the option list
(not sure why mpv does that anyway) only has the potential to mess
this process up when it prints errors or the user has funny options
like msg-level or log-file set, so avoid doing so.
In sum there were three issues:
1. nominal_peak_luminance is an output parameter, not input
2. mpv internally uses MP_REF_WHITE which we need to scale by
3. the value should be left at its default for SDR
Together with the last change this means mpv can sucessfully
take HDR screenshots with --screenshot-sw without resulting
in a brightly colored mess. Though note that zimg does not
perform proper tonemapping.
As a consequence:
- write_avif now respects tag-colorspace=no
- write_lavc additionally sets colorspace and chroma_location
(of no consequence for png or jpeg)
mpv has historically always treated the various tiled states in
xdg-shell as maximized (probably because it was easier). Well it turns
out that there are some tiling compositors (hyprland) that allow tiled
windows to maximize themselves. This can lead to some scenarios where
mpv ends up doing a maximize on hyprland which actually works since it's
not a no-op like on sway. Fix this by separating out the tiled state
from maximize. It works mostly the same, but the main difference is that
there's no request to tile yourself like there is with maximize. Should
fix#11954.
There's a lot of checks that are along the lines of !maximized &&
!minimized or vice versa. Make a locked_size boolean and store the
value of this in here to avoid writing long lines since the next commit
will add yet another condition to this.
There is an additional failure path I didn't account for in my previous
work. While I ensured that a late hwdec failure in receive_frame can be
recovered from by trying the next hwdec, there is a specific
combination where if an hwdec fails in receive_frame, and the next
hwdec is a full decoder (eg: v4l2m2m), and that also fails, we are left
with no decoder and so the entire decoding process ends and playback is
stopped.
Basically, we must keep re-attempting the fallback in receive_frame
until we get a valid decoder (software or hardware). This edge case
will rarely be encountered as there are only a couple of decoder based
hwdecs.
Fixes#11947
I don't know why we've been doing this wrong for so long or how I didn't
notice until now. Wayland specifically has an event for handling
modifiers. We even named it "keyboard_handle_modifiers" in the code.
What we should do is just get the modifier and save it after the xkb
state is updated. Then later if the user does something else (press
another key or clicks the mouse button), the saved modifier key is
applied. If you let go of the modifier at any point, the xkb will just
update its state again and we save a 0 again here (i.e. no modifier).
There is one bit of an edge case however. If a key is pressed BEFORE the
modifier, then we have to handle the mp_input_put_key in the modifier
event instead since the ordering is not guarenteed. What we do here is
keep track of the mpkey as well as the mpmod. However if we are unable
to find a matching mpkey and the key state is pressed down, assume it's
a modifery key that was pressed and don't update mpkey. That way
whenever the modifier event does happen, it can correctly handle this
and we know that the keys must be pressed down if we end up there in the
code path.
As another fun historical note, the xkb_keysym_to_utf8 line was actually
written by wm4 himself in 460ef9c7a4
nearly 10 years ago. As the commit shows, it was clearly intended to
handle modifiers (if lookupkey finds nothing, then try to find a mod
instead). Of course, this is extremely dated and wayland hasn't worked
like that in ages. This branch never actually did anything, and thus
we'll remove it here along with modifier lookup changes.
This solves bizarre issues with modifiers not working with random keys
while working fine with others (don't ask me why). Fixes#10286 and
fixes#11945.
When using lavfi-complex, no single track populates current_track for audio.
We work around this by iterating over the list of tracks and using the first
non-null language from a selected track. If multiple tracks are selected
(i.e. used by the filter) and have conflicting language tags, we'll ignore
them all and maintain the previous behavior (null).
828dd65ef8 started this and put it in the
most common place, but any resize mpv is doing should be accompanied by
that function call to correctly inform the compositor of the window
bounds. Since we also have to set VO_EVENT_RESIZE at the same time, it
makes sense to just put these in the same function. A slight thing to
note is that xdg_surface_set_window_geometry uses surface local
coordinates which means they are divided by the wl->scaling factor. If
possible, we should use surface local coordinates directly if available
(like in the toplevel config) to avoid potential rounding errors.
Otherwise, just calculate it out. The linked commit actually broke
some weston resizes in weird ways (window disappearing or completely
freezing). Don't ask me why and I didn't attempt to find out why either,
but with this it all appears to work normally again (the other
compositors don't appear to be any different, and they shouldn't be), so
we'll go with this since it fixes soemthing and it also is more
conceptually correct.
Libass commit f08f8ea5 (between 0.16 and 0.17) changed how PlayResX
affects some aspects of rendering.
The libass change fixes a VSFilter compatibility issue which existed
for about two decades, and there are no libass plans to support the
previous behavior, so ultimately we have to adjust the mpv code, and
we can't guarantee to restore the old behavior in all cases.
Starting at this commit, vector drawing coords, font spacing, border
and shadow widths are all affected by PlayResX (specifically, by
the aspect), while previously they were unaffected by PlayResX.
This changed converted sub border and shadow widths in mpv, because
ffmpeg generates the ass with fixed PlayResX of 384 (aspect of 4:3),
and with libass 0.17, if this doesn't match the display aspect, then
borders and shadow were too wide - because most clips aspect is more
than 4:3.
The fact that ffmpeg uses fixed PlayResX of 384 could be considered
an issue, but for now we have no control over it, and ffmpeg doesn't
have the video resolution when it converts an srt source to ass.
So here we adjust PlayResX accordingly so that border/shadows are
now rendered with correct width.
However, regardless of that commit, changing PlayResX also affects
the margin value, so to compensate, we adjust sub-margins-x too.
According to libass devs, this should cover basic srt-to-ass
conversion by ffmpeg to work correctly with libass 0.17.
However, there could be srt extensions which use more complex ass,
and/or ffmpeg conversion of other sub formats (such as aribb24,
aribcaption and movtext), where more things need adjustments.
As of now we don't know what these are, and so we don't really know
what else might remain broken or get broken.
dbc5d7b7db seems to have originally
introduced this behavior. At the time, wm4 simply reconfigured ass on
every frame in order to accommodate runtime changes in sub options. This
certainly works, but these libass API calls are not free and there is at
least one known performance regression due to a change in libass*.
Regardless of whether or not the libass change is good/bad, there is no
need for mpv to constantly reconfigure this. When wm4 made that commit,
there was no notification mechanism for options changing that could
easily be used so he didn't really have any other choice. But it's
nearly 10 years later now and internally we have all the necessary
pieces to only configure ass again when we need to: on option changes or
resizes. So go ahead and implement that in this commit which simply uses
the already existing SD_CTRL_UPDATE_OPTS and compares osd_res sizes to
determine whether or not an ass configure is needed.

4502522a7a implemented cache directories
but only on linux which meant other OSes continued to save this stuff in
their config directory. Since we turned on cache by default, people are
getting cache files in there which is understandably causing some
confusion. Let's go ahead and implement a separate cache directory for
windows since there seems to be some established conventions for this
already. For people using the portable_path, the cache is saved in a
subdirectory within the portable_path since the idea is for that to be
completely self contained.
To remain consistent with our belief that `auto-safe` should be the
recommended mode when turning on hw decoding, let's remap `yes` from
`auto` to `auto-safe`.
We have supported `hwdec=drm` for some time now, and on devices where
this method is present, it is the preferred, and only, method
available. Combine that with the fact that software decoding on
embedded devices will not turn out well, and it's clear that we should
put `drm` and `drm-copy` on the `auto-safe` list to maximise usability
in simple configurations.
It has been odd that ctrl+h toggles `auto` for hwdecs even though we
always recommend people start with `auto-safe`, and `auto` will attempt
various hwdecs that can fail so badly we can't fall back to software
decoding.
With the change to more exhaustively attempt to use hwdecs, it is now
easier to get into situations where these fragile hwdecs will get
attempted in basic scenarios, like pressing ctrl+h.
So it is high time to default to `auto-safe`.
Today, if hwdec initialisation succeeds, we move on to attempting
decoding, and if decoding fails, we enter a fallback path that will
only do software decoding.
This is suboptimal because some hwdecs and codec combinations can
pass hwdec init, but then fail at hwaccel init, or even frame decoding.
In these situations, we will never attempt other hwdecs in the `auto`
or manually specified lists which might work.
One good example is someone tries to use `vulkan,auto` and tries to
play av1 content. The vulkan decoding will fail at hwaccel init time,
and then fallback to software instead of going through the auto list
which would allow vaapi, nvdec, etc to play the file.
Instead, let's not give up immediately, and try the next hwdec after
a failure, just like we do if hwdec init fails.
The key part of this change is to keep track of the hwdecs we have
tried, so that each time we run through hwdec selection, we don't try
the same one over and over again. If we really get through the whole
list with no success, we will then fall back to software decoding.
Fixes#11865
