Since this is guarded behind strict unofficial, we should warn if the
user feeds a dolby vision stream to this muxer, as it will otherwise
result in a broken file.
This function takes a decoded AVDOVIMetadata struct and turns it back
into a binary RPU. Verified using existing tools, and matches the
bitstream in official reference files.
I decided to just roll the EMDF and NAL encapsulation into this function
because the end user will need to do it otherwise anyways.
We need to set up the configuration struct appropriately based on the
codec type, colorspace metadata, and presence/absence of an EL (though,
we currently don't support an EL).
When present, we use the signalled RPU data header to help infer (and
validate) the right values.
Behavior can be controlled by a new DOVIContext.enable flag.
To allow compiling the decoding objects without the encoding objects and
vice versa. Common helpers that users of both APIs need are put into the
shared dovi_rpu.c.
To allow internally re-using it for both the encoder and decoder.
This is based on HEVC only, H.264/AV1 use their own (hopefully correctly
signalled) profiles (and in particular, the AV1 decoders implicitly
default the correct profile in the absence of a configuration record).
The code was written under the misguided assumption that these fields
would only be present when the value changes, however this does not
match the actual patent specification, which says that streams are
required to either always signal this metadata, or never signal it.
That said, the specification does not really clarify what the defaults
of these fields should be in the event that this metadata is missing, so
without any sample file or other reference I don't wish to hazard
a guess at how to interpret these fields.
Fix the current behavior by making sure we always throw this error, even
for files that have the vdr sequence info in one frame but are missing
it in the next frame.
And make it public.
For encoding, users may also be interested in the configured level and
compatibility ID. So generalize the dv_profile field and just expose the
whole configuration record.
This makes the already rather reductive ff_dovi_update_cfg() function
almost wholly redundant, since users can just directly assign
DOVIContext.cfg.
AV1 can put a frame into multiple reference slots;
up until now, this involved creating a new reference
to the underlying AVFrame; therefore av1_frame_ref()
could fail.
This commit changes this by using the ProgressFrame API
to share the underlying AVFrames.
(Hint: vaapi_av1_surface_id() checked whether the AV1Frames
contained in the AV1DecContext were NULL or not (of course
they were not); this has been changed to actually check for
whether said AV1Frame is blank or not.)

When we used the --disable-ssse3 --disable-optimizations options,
the compiler would not skip the MC_LINKS like the compilation that
enabled the optimization, so it would fail to find the function
prototypes. Hence, this commit uses the same way to add prototypes
for the functions as HEVC DSP.
And, when prototypes are added for the functions, we cannot add the static qualifier.
Therefore, the ff_vvc prefix is needed to avoid the naming conflict.

After having created the AVBuffer that is put into frame->buf[0],
ownership of several objects (namely an AVDRMFrameDescriptor,
an MppFrame and some AVBufferRefs framecontextref and decoder_ref)
has passed to the AVBuffer and therefore to the frame.
Yet it has nevertheless been freed manually on error
afterwards, which would lead to a double-free as soon
as the AVFrame is unreferenced.

Avoids implicit av_frame_ref() and therefore allocations
and error checks. It also avoids explicitly allocating
the AVFrames (done implicitly when getting the buffer).
It also fixes a data race: The AVFrame's sample_aspect_ratio
is currently updated after ff_thread_finish_setup()
and this write is unsynchronized with the read in av_frame_ref().
Removing the implicit av_frame_ref() fixed this.

Before commit f025b8e110,
every frame-threaded decoder used ThreadFrames, even when
they did not have any inter-frame dependencies at all.
In order to distinguish those decoders that need the AVBuffer
for progress communication from those that do not (to avoid
the allocation for the latter), the former decoders were marked
with the FF_CODEC_CAP_ALLOCATE_PROGRESS internal codec cap.
Yet distinguishing these two can be done in a more natural way:
Don't use ThreadFrames when not needed and split ff_thread_get_buffer()
into a core function that calls the user's get_buffer2 callback
and a wrapper around it that also allocates the progress AVBuffer.
This has been done in 02220b88fc
and since that commit the ALLOCATE_PROGRESS cap was nearly redundant.
The only exception was WebP and VP8. WebP can contain VP8
and uses the VP8 decoder directly (i.e. they share the same
AVCodecContext). Both decoders are frame-threaded and VP8
has inter-frame dependencies (in general, not in valid WebP)
and therefore the ALLOCATE_PROGRESS cap. In order to avoid
allocating progress in case of a frame-threaded WebP decoder
the cap and the check for the cap has been kept in place.
Yet now the VP8 decoder has been switched to use ProgressFrames
and therefore there is just no reason any more for this check
and the cap. This commit therefore removes both.
Also change the value of FF_CODEC_CAP_USES_PROGRESSFRAMES
to leave no gaps.

ff_thread_progress_replace() can handle a blank ProgressFrame
as src (in which case it simply unreferences dst), but not

this case, so that we can use the replace functions
