I've decided that MP_TRACE means “noisy spam per frame”, whereas
MP_DBG just means “more verbose debugging messages than MSGL_V”.
Basically, MSGL_DBG shouldn't create spam per frame like it currently
does, and MSGL_V should make sense to the end-user and provide mostly
additional informational output.
MP_DBG is basically what I want to make the new default for --log-file,
so the cut-off point for MP_DBG is if we probably want to know if for
debugging purposes but the user most likely doesn't care about on the
terminal.
Also, the debug callbacks for libass and ffmpeg got bumped in their
verbosity levels slightly, because being external components they're a
bit less relevant to mpv debugging, and a bit too over-eager in what
they consider to be relevant information.
I exclusively used the "try it on my machine and remove messages from
MSGL_* until it does what I want it to" approach of refactoring, so
YMMV.
Annoying exception that makes no sense to keep. Normally, users or
client applications will either use --hwdec=auto, or not set the option
at all, which both leads to the expected result.
Full range YUV causes problems everywhere. For example it's usually the
wrong choice when using encoding mode, and libswscale sometimes messes
up when converting to full range too. (In this partricular case, we
found that converting rgba->yuv420p16 full range actually seems to
output limited range.)
This actually restores a similar heueristic from the late vf_scale.c.
When autoprobing the hwdec interops (which now happens to all compiled
interops if hardware decoding is used), failure to load an interop
should not print an error in the normal case. So hide it.
(We could make the log level conditional on whether autoprobing is used,
but directly loading it without autoprobing is obscure, and most other
interops don't do this either.)
For METHOD_INTERNAL hwdecs (non-copy cases), make sure the VO interops
are always loaded, because those decoders will output hardware pixel
formats, which will need special support in vo_gpu. Otherwise,
initialization will fail, complaining that it can't convert the output
format to something the VO supports.
* Distinguish between the window being moved or not.
* Skip trying to snap if currently in full screen or an embedded
window.
* Exit snapped state if the size changed when the window was being
moved.
Check the expected width and height against up-to-date
window placement. If they do not match, we will consider snapping
to have happened on Windows' side.
Fixes display-sync (though if you change virtual desktops you'll need to seek
to re-enable display-sync) partially under wayland.
As an advantage, rendering is completely disabled if you change desktops or
alt+tab so you lose no performance if you leave mpv running elsewhere as long
as it isn't visible.
This could also be ported to other VOs which supports it.
We need to support hardware/drivers which do not support ARGB8888 in
their primary plane.
We also use p->primary_plane_format when creating the gbm surface, to
make sure it always matches (in actuality there should be little
difference).
Passing in an invalid DRM overlay id with the --drm-overlay option would
cause drmplane to be freed twice: once in the for-loop and once at the
error-handler label fail.
Solve by setting drmpanel to NULL after freeing it.
Also the 'return false' statement after the error handler label should
probably be 'return NULL', given that the return type of
drm_atomic_create_context returns a pointer.
vo_x11 and vo_xv need this. According to the Linux manpage, all involved
functions are POSIX-2001 anyway. (I just assumed they were not, because
they're mostly System V UNIX legacy garbage.)
If the codec uses AV_CODEC_HW_CONFIG_METHOD_INTERNAL, and we're using
the -copy method, then don't request the native pix_fmt. It might not
have a AVFrame.hw_frames_ctx set, and we couldn't read back at all. On
top of that, most of those decoders probably don't provide read-back
when using such opaque formats anyway, while providing separate decoding
modes to decode to RAM.
Finally get rid of all the HWDEC_* things, and instead rely on the
libavutil equivalents. vdpau still uses a shitty hack, but fuck the
vdpau code.
Remove all the now unneeded remains. The vdpau preemption thing was not
unused anymore; if someone cares this could probably be restored.
This code is for trying to avoid using an emulation layer when using
auto probing, so that we end up using the actual API the drivers
provide. It was destroyed in the recent refactor.
With the recent changes, mpv's internal mechanisms got synced to
libavcodec's once more. Some things are still needed for filters (until
the mechanism gets replaced), but there's no need to require other hwdec
methods to use these fields. So remove them where they are unnecessary.
Also fix some minor leaks in the dxva2 backends, and set the driver_name
field in the Apple ones. Untested on Apple crap.
Otherwise, if e.g. "nvdec" didn't work, but "nvdec-copy" did, it would
never try "vdpau", which is actually the next non-copy mode on the
autprobe list. It's really expected that it selects "vdpau". Fix this by
sorting the -copy modes to the end of the final hwdec list.
But we still don't want preferred -copy modes like "nvdec-copy" to be
sorted after fragile non-preferred modes like "cuda", and --hwdec=auto
should prefer "nvdec-copy" over it, so make sure the copying mode does
not get precedence over preferred vs. non-preferred mode.
Also simplify the existing auto_pos sorting condition, and fix the
fallback sort order (although that doesn't matter too much).
Change it from explicit metadata about every hwaccel method to trying to
get it from libavcodec. As shown by add_all_hwdec_methods(), this is a
quite bumpy road, and a bit worse than expected.
This will probably cause a bunch of regressions. In particular I didn't
check all the strange decoder wrappers, which all cause some sort of
special cases each. You're volunteering for beta testing by using this
commit.
One interesting thing is that we completely get rid of mp_hwdec_ctx in
vd_lavc.c, and that HWDEC_* mostly goes away (some filters still use it,
and the VO hwdec interops still have a lot of code to set it up, so it's
not going away completely for now).
The libavcodec mediacodec support does not conform to the new hwaccel
APIs yet. It has been agreed uppon that this glue code can be deleted
for now, and support for it will be restored at a later point.
Readding would require that it supports the AVCodecContext.hw_device_ctx
API. The hw_device_ctx would then contain the surface ID.
vo_mediacodec_embed would actually perform the task of creating
vo.hwdec_devs and adding a mp_hwdec_ctx, whose av_device_ref is a
AVHWDeviceContext containing the android surface.
It makes more sense to have it in the general video directory (along
with vdpau.c and vaapi.c), since the decoder source files don't even
access it anymore.
Like with all hwaccels, there's little that is actually specific to
decoding (which has been moved away anyway), and what is left are
declarations (which will also go away soon).
Lots of shit code for nothing. We probably could just use libavutil's
code for all of this. But for now go with this, since it tends to
prevent stupid terminal messages during probing (libavutil has no
mechanism to selectively suppress errors specifically during probing).
Ignores the "emulated" API flag (for avoiding vaapi/vdpau wrappers), but
it doesn't matter that much for -copy anyway.
This leaked 2 unreffed AVFrame structs (roughly 1KB) per decoded frame.
Can I blame the FFmpeg API and the weird difference between freeing and
unreffing an AVFrame?
The idea is to get rid of vd_lavc_hwdec, so special functionality like
this has to go somewhere else. At this point, hwframes_refine is only
needed for d3d11, and it doesn't do much, so for now the new callback
has no context. In can be made more fancy if really needed.
The testing_only field is not referenced anymore with vaglx removed and
the previous commit dropping all uses.
The ra_hwdec_driver.api field became unused with the previous commit,
but all hwdec interop drivers still initialized it.
Since this touches highly OS-specific code, build regressions are
possible (plus the previous commit might break hw decoding at runtime).
At least hwdec_cuda.c still used the .api field, other than initializing
it.
