There's no need to keep using a custom decoder for this pixel format.

It's not modified, so we can simply use a const pointer to it.
Also check the return value of the other copy in the function while at it.

nvenc does not appear to use these values as inputs for its built in RGB
to YUV conversion, but instead sets them on the output as-is.
Testing indicates the input is expected to be sRGB, with the output
ending up as limited range bt.470.
|
|
|
|
|
|
| |
According to MSDN, all integer pixel formats contains sRGB compliant
pixel data, so set the color information on our output frames
accordingly.

Most notably, the input hw_device_ctx is not set at init time, so using it was impossible.

Up until now, there were four copies of
quantize_and_encode_band_cost_(ZERO|[SU]QUAD|[SU]PAIR|ESC|NONE|NOISE|STEREO)
(namely in aaccoder.o, aacenc_is.o, aacenc_ltp.o, aacenc_pred.o).
As 43b378a0d321e3d01f196cec95e13acfac80d464 says, this is meant to
enable more optimizations.
Yet neither GCC nor Clang performed such optimizations: The functions
in the aforementioned files are not optimized according to
the specifics of the calls in the respective file. Therefore
duplicating them is a waste of space; this commit therefore stops doing
so. The remaining copy is placed into aaccoder.c (which is the only
place where the "round to zero" variant of quantize_and_encode_band()
is used, so that this can be completely internal to aaccoder.c).

Also constify the corresponding code in mpegvideo.c that handles
lowres.
(Unfortunately, not everything that is const could be constified:
ref_picture could be made const uint8_t* const* if C allowed the
safe automatic conversion from uint8_t**; and pix_op, qpix_op
could be made to point to const function pointers, but C's handling
of const in pointers to arrays is broken.)

__lasx_xvldx does not accept a pointer to const (in fact,
no function in lasxintrin.h does so), although it is not allowed
to modify the pointed-to buffer. Therefore this commit adds a wrapper
for it in order to constify the H264Chroma API in a later commit.

Now that we have a combination of capable hardware (new enough Intel)
and a mutually understood format ("AYUV"), we can declare support for
decoding 8bit 4:4:4 content via VAAPI.
This requires listing AYUV as a supported format, and then adding VAAPI
as a supported hwaccel for the relevant codecs (HEVC and VP9). I also
had to add VP9Profile1 to the set of supported profiles for VAAPI as it
was never relevant before.
|
|
|
|
| |
This is the format used by Intel VAAPI for 8bit 4:4:4 content.
|
|
|
|
|
|
|
|
|
| |
The "AYUV" format is defined by Microsoft as their preferred format for
4:4:4 content, and so it is the format used by Intel VAAPI and QSV.
As Microsoft like to define their byte ordering in little-endian
fashion, the memory order is reversed, and so our pix_fmt, which
follows memory order, has a reversed name (VUYA).

To do so, store the pointer to the VLC table and not to the VLC.
This is possible, because all the VLCs of the same type use
the same number of bits.
Also use a const VLCElem*, because the target is static and must
therefore not be modified after its initialization.

The msmpeg4 decoders/encoders share a common set of prerequisites,
ergo it makes sense to use common subsystems for them. This also
allows to remove the CONFIG_MSMPEG4_DECODER/ENCODER ad-hoc defines
(which violated the CONFIG_ namespace).

IntraX8 uses WMV2DSP directly, so it should have a direct dependency
on it. Also remove the indirect Makefile dependency of the VC-1 decoder
on wmv2dsp.o. Notice that since the addition of the MIPS WMV2DSP
implementation building only the VC-1 decoder would fail, because
no Makefile dependency VC1->wmv2dsp_init_mips.o has been added.
This is of course fixed by this commit.

Firstly, the timestamps generated from framerate are inaccurate for
variable framerate mode.
Secondly, the timestamps always start from zero, while pts/dts can
start from nonzero. FLV demuxer rejects such index with message:
"Found invalid index entries, clearing the index".

Usually a HW decoder is expected when user specifies a HW acceleration
method via -hwaccel option, however the current implementation doesn't
take HW acceleration method into account, it is possible to select a SW
decoder.
For example:
$ ffmpeg -hwaccel vaapi -i av1.mp4 -f null -
$ ffmpeg -hwaccel nvdec -i av1.mp4 -f null -
$ ffmpeg -hwaccel vdpau -i av1.mp4 -f null -
[...]
Stream #0:0 -> #0:0 (av1 (libdav1d) -> wrapped_avframe (native))
libdav1d is selected in this case even if vaapi, nvdec or vdpau is
specified.
After applying this patch, the native av1 decoder (with vaapi, nvdec or
vdpau support) is selected for decoding(libdav1d is still used for
probing format).
$ ffmpeg -hwaccel vaapi -i av1.mp4 -f null -
$ ffmpeg -hwaccel nvdec -i av1.mp4 -f null -
$ ffmpeg -hwaccel vdpau -i av1.mp4 -f null -
[...]
Stream #0:0 -> #0:0 (av1 (native) -> wrapped_avframe (native))
