This new hwaccel flag was added to allow us to request that an hwaccel
decode not implicitly copy output frames before passing them out. The
only hwaccel that would implicitly copy frames is nvdec due to how it
has a small output pool that cannot be grown very much. However, we
already copy frames as soon as we get our hands on them (in our hwdec)
so we're already safe from pool exhaustion, and the extra copy doesn't
help us.
H264 hardware decode with v4l2m2m wasn't working on the RPi 4. Mpv would
report the image format (yuv420p) wasn't supported. The change to
hwdec_drmprime.c is to explicitly say that the format now is supported.
The change to dmabuf_interop_gl.c is to specify the colour format of the
planes before generating egl images. These changes were tested on a Pi 4
with this fork of ffmpeg: https://github.com/jc-kynesim/rpi-ffmpeg.

currently only supported on x11.
one practical use-case of this is wanting to embed something (such as
dmenu) into the mpv window to use as a menu/selection. there might be
other use-cases as well (e.g doing some shenanigans with `xdotool` or
whatnot).
it's currently possible to:
* listen for 'current-window-scale' change (to check if the
window has been created or not)
* call an external tool like `xdo` or `xdotool` and grab the xid
from mpv's pid.
however it adds unnecessary dependency on external tools when mpv is
fully capable of easily providing this information.

This has been a long standing annoyance - ffmpeg is removing
sizeof(AVPacket) from the API which means you cannot stack-allocate
AVPacket anymore. However, that is something we take advantage of
because we use short-lived AVPackets to bridge from native mpv packets
in our main decoding paths.
We don't think that switching these to `av_packet_alloc` is desirable,
given the cost of heap allocation, so this change takes a different
approach - allocating a single packet in the relevant context and
reusing it over and over.
That's fairly straight-forward, with the main caveat being that
re-initialising the packet is unintuitive. There is no function that
does exactly what we need (what `av_init_packet` did). The closest is
`av_packet_unref`, which additionally frees buffers and side-data.
However, we don't copy those things - we just assign them in from our
own packet, so we have to explicitly clear the pointers before calling
`av_packet_unref`. But at least we can make a wrapper function for
that.
The weirdest part of the change is the handling of the vtt subtitle
conversion. This requires two packets, so I had to pre-allocate two in
the context struct. That sounds excessive, but if allocating the
primary packet is too expensive, then allocating the secondary one for
vtt subtitles must also be too expensive.
This change is not conditional as heap allocated AVPackets were
available for years and years before the deprecation.
Now that 0.35 has been released, we can consider increasing our minimum
required ffmpeg version. Currently, we think 4.4 is the most recent
version we can move to (from the current requirement of 4.0).
This allows us to remove a few conditionals. There are more that we
won't be able to remove unless we move further up to 5.1.
8300830951 rearranged/simplified some of
the wayland touch code mainly because what was there before was
completely broken on my machine in those days (dragging was unreliable,
resizing was really buggy, etc.). However, one user said that touch
input no longer worked for him after that change. I could not ever
reproduce it, but it seems the issue was putting down the key before
testing for resize/move in the code. Now who knows why this actually
matters, but apparently it works for the user in question and I don't
observe any unexpected behavior on my end when swapping the order. Like
the mouse/pointer code, we also now do a test for dragging before
actually trying a resize/move which is a little more consistent than
before. Fixes#9771.
Not sure when this actually started happening, but it's probably been
like this for years. Currently, the logic for the window-controls works
by simply checking if the osc is visible and then either enabling or
disabling the associated keybindings. The problem is that this can just
constantly spam mp.enable_keybindings/disable_key_bindings on every
single render call if the user disables the border at any point in time.
This does a lot of pointless work and also results in the logs being
spammed with lines like "disable-section". Clearly, this should just
work like the code for checking the input keybindings just above it.
Keep track of an internal state variable and check when it doesn't match
the osc visibility. In that case, we can then either enable or disable
the key bindings and just update the variable.
This allows us to more easily see the datapath from mpv to pipewire.
We know how often the callbacks are triggered, how big the buffers are
and how much data mpv provides to pipewire.
Flushing the cache is a hammer-for-a-screw operation, because it nukes
*all* renderer state, including the HDR peak detection state. When
enabling e.g. --hdr-compute-peak, or any other future methods of dynamic
tone mapping, this would lead to bad results (e.g. brightness
fluctuations) whenever the OSD state is updated.
Instead of flushing the cache to force an OSD re-render, instead just
update the frame signature directly whenever its osd_sync value changes.
This accomplishes effectively the same thing but without touching the
HDR state.
This is slightly violating the libplacebo abstraction in a way that
isn't publicly documented. To be on the safe side we could make a carbon
copy of the array before modifying it, but given that this is unlikely
to change upstream I'll probably just end up explicitly documenting it
instead of forcing the copy in mpv.
BSDs use compiler-rt instead of libatomic for atomic types. In this
case, we can handle it similar to how dl is detected. Check for the
library (allowing for it to fail), and then check for a header symbol
while linking latomic. Fixes#10906.
Currently, the lcms-related options are only defined when lcms2 is
enabled at build time. However, this causes issues (e.g. segfault) for
vo_gpu_next, which relies on the presence of these options (to forward
them to libplacebo).
(That libplacebo internally depends on lcms2 as well is an
implementation detail - compiling mpv *without* lcms against libplacebo
*with* lcms should be possible in principle)

The new single-pixel-buffer protocol is designed to optimize the case
for using a solid color as an underlay wl_surface. It works the same as
the wl_shm 1x1 pixel trick currently used, but it allows the compositor
to make optimizations with more certainty than the wl_shm trick.
This was previously implicitly included by the order of headers in
vo_dmabuf_wayland.c, but it is better to make it an explicit and reorder
the headers properly.
Meson uses the sysconfdir option for setting the global config
directory. This conveniently defaults to /etc if the prefix is set to
/usr which is nice for linux distros. BSDs tend to use /usr/local which
causes this value to become 'etc' by default which is not an absolute
path so you would need to set something like -Dsysconfdir=/usr/local/etc
as well in the configuration step. It turns out we can have our cake and
eat it too by just joining the paths of prefix and sysconfdir together.
In the case where -Dprefix=/usr, this still results in /etc/mpv as the
path since the path joining logic just drops the leading '/usr/'. For
the /usr/local case, it ends up as /usr/local/etc/mpv as expected. This
fixes#10882.
When the alpha channel is the first component, this code block gets
skipped by the continue, meaning the check for c==0 never passes.
Fix it by explicitly keeping track of whether bits have been set.
The legacy DRM API adds some complexity to the DRM code. There
are only 4 drivers that do not support the DRM Atomic API:
1. radeon (early GCN amd cards)
2. gma500 (ancient intel GPUs)
3. ast (ASPEED SoCs)
4. nouveau
Going forward, new DRM drivers will be guaranteed to support the atomic
API so this is a safe removal.
The content-type protocol allows mpv to send compositor a hint about the
type of content being displayed on its surface so it could potentially
make some sort of optimization. Fundamentally, this is pretty simple but
since this requires a very new wayland-protocols version (1.27), we have
to mess with the build to add a new define and add a bunch of if's in
here. The protocol itself exposes 4 different types of content: none,
photo, video, and game.
To do that, let's add a new option (wayland-content-type) that lets
users control what hint to send to the compossitor. Since the previous
commit adds a VOCTRL that notifies us about the content being displayed,
we can also add an auto value to this option. As you'd expect, the
compositor hint would be set to photo if mpv's core detects an image,
video for other things, and it is set to none for the special case of
forcing a window when there is not a video track. For completion's sake,
game is also allowed as a value for this option, but in practice there
shouldn't be a reason to use that.
mpv's core already keeps track of whether or not it thinks a track is an
image. Some VOs (i.e. wayland) would benefit from knowing if what is
currently being displayed is an image or not so add a new VOCTRL that
signals this anytime we load a new file with a VO. Additionally, let's
add a helper enum for signaling the kind of content that is being
displayed. There is now MP_CONTENT_NONE (strictly for force window being
used on a track with no image/video), MP_CONTENT_IMAGE, and
MP_CONTENT_VIDEO. See the next commit for the actual usage of this (with
wayland).
mpv has an internal optimization on a couple of platforms where it will
not render any frames if the window is minimized or hidden. There's at
least once possible use case for wanting to force a render anyway
(screensharing with pipeware) so let's just add a simple switch for
this that always forces mpv to render. Closes#10846.
Related issue: #10868. While most protocols are in theory optional, a
small amount of them are absolutely essential and nothing will work
without them. We should make sure to error out in those cases and not
try to actually do anything. For wayland support in general,
wl_compositor support is obviously required. If there is no wl_surface,
you can't do anything. Additionally, vo_wlshm quite obviously requires
wl_shm so mark that one as well. vo_dmabuf_wayland needs linux_dmabuf,
viewporter, wl_shm, and wl_subcompositor. In practice, these are all
very standard protocols and shouldn't be missing but the linked issue
above is at least one example where a compositor was stuck on an ancient
version of a wayland interface.
Apparently, it is possible for touchbar.m to compile on non-macos
machines. Also, the disable switch didn't actually work either. Fix this
by using the require() function and making sure that Cocoa (should be
apple-only) is found in addition to the compile check passing which is
what waf does. Fixes#10847.
