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).
This is never updated after the AO inits, so there are several cases
where the volume would stay at 100%, even if it shouldn't. This affects
initial volume as well as track switching or switching between files.
dlopen() and dlsym() can fail in various ways, and we can find out
how it failed by calling dlerror(). This is particularly useful if
you typo the filename of a script when explicitly passing it with
--script, and dlopen actually tells you that the file doesn't exist
instead of leading you down a rabbit hole of disassembling your
shared object file to figure out why the thing won't load.
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).
Seems like they finally got rid of this. It was the first lavc vdpau
API, and mpv stopped supporting it in favor of newer APIs a long time
ago, causing confusion to users who tried to enable vdpau decoding by
forcing the decoders (MPlayer style).
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.
Make the VO<->decoder interface capable of supporting multiple hwdec
APIs at once. The main gain is that this simplifies autoprobing a lot.
Before this change, it could happen that the VO loaded the "wrong" hwdec
API, and the decoder was stuck with the choice (breaking hw decoding).
With the change applied, the VO simply loads all available APIs, so
autoprobing trickery is left entirely to the decoder.
In the past, we were quite careful about not accidentally loading the
wrong interop drivers. This was in part to make sure autoprobing works,
but also because libva had this obnoxious bug of dumping garbage to
stderr when using the API. libva was fixed, so this is not a problem
anymore.
The --opengl-hwdec-interop option is changed in various ways (again...),
and renamed to --gpu-hwdec-interop. It does not have much use anymore,
other than debugging. It's notable that the order in the hwdec interop
array ra_hwdec_drivers[] still matters if multiple drivers support the
same image formats, so the option can explicitly force one, if that
should ever be necessary, or more likely, for debugging. One example are
the ra_hwdec_d3d11egl and ra_hwdec_d3d11eglrgb drivers, which both
support d3d11 input.
vo_gpu now always loads the interop lazily by default, but when it does,
it loads them all. vo_opengl_cb now always loads them when the GL
context handle is initialized. I don't expect that this causes any
problems.
It's now possible to do things like changing between vdpau and nvdec
decoding at runtime.
This is also preparation for cleaning up vd_lavc.c hwdec autoprobing.
It's another reason why hwdec_devices_request_all() does not take a
hwdec type anymore.
nvdec aka cuvid aka cuda should work much better than vdpau, and support
newer codecs (such as vp9), and more advanced surface formats (like 10
bit).
This requires moving the d3d hwaccels in the autoprobe order, since on
Windows, d3d decoding should be preferred over nvidia proprietary stuff.
Users of older drivers will need to force --hwdec=vdpau, since it could
happen that the vo_gpu cuda hwdec interop loads (so the vdpau interop is
not loaded), but the hwdec itself doesn't work.
I expect this does not break AMD (which still needs vdpau for vo_gpu
interop, until libva is fixed so it can fully support AMD).
This has stopped being useful a long time ago, and it's the only GPL
source file in the vo_gpu source directories. Recently it wasn't even
loaded at all, unless you forced loading it.
stdatomic.h defines no atomic_float typedef. We can't just use _Atomic
unconditionally, because we support compilers without C11 atomics. So
just create a custom atomic_float typedef in the wrapper, which uses
_Atomic in the C11 code path.
This does what af_volume used to do. Since we couldn't relicense it,
just rewrite it. Since we don't have a new filter mechanism yet, and the
libavfilter is too inconvenient, do applying the volume gain in ao.c
directly. This is done before handling the audio data to the driver.
Since push.c runs a separate thread, and pull.c is called asynchronously
from the audio driver's thread, the volume value needs to be
synchronized. There's no existing central mutex, so do some shit with
atomics. Since there's no atomic_float type predefined (which is at
least needed when using the legacy wrapper), do some nonsense about
reinterpret casting the float value to an int for the purpose of atomic
access. Not sure if using memcpy() is undefined behavior, but for now I
don't care.
The advantage of not using a filter is lower complexity (no filter auto
insertion), and lower latency (gain processing is done after our
internal audio buffer of at least 200ms).
Disavdantages include inability to use native volume control _before_
other filters with custom filter chains, and the need to add new
processing for each new sample type.
Since this doesn't reuse any of the old GPL code, nor does indirectly
rely on it, volume and replaygain handling now works in LGPL mode.
How to process the gain is inspired by libavfilter's af_volume (LGPL).
In particular, we use exactly the same rounding, and we quantize
processing for integer sample types by 256 steps. Some of libavfilter's
copyright may or may not apply, but I think not, and it's the same
license anyway.
Oops. This is part of the TV code, for which we didn't make any effort
to relicense. But files were always built, because they didn't depend on
the common TV code. (The HAVE_GPL in the source file exposed this by
making the build fail.)
These couldn't be relicensed, and won't survive the LGPL transition. The
other existing filters are mostly LGPL (except libaf glue code).
This remove the deprecated pan option. I guess it could be restored by
inserting a libavfilter filter (if there's one), but for now let it be
gone.
This temporarily breaks volume control (and things related to it, like
replaygain).
