The function is called only internally in DSP, so we do not
need to expose it.
apply_ltp on MIPS uses this function, but due to the function
being just a glue function with no real optimizations,
duplicate it there.
Up until now, there was one AACDecContext for the fixed
and one for the floating point decoder. These differed
mostly in certain arrays which were int for the fixed-point
and float for the floating point decoder; there were also
differences in corresponding function pointers.
Yet in order to deduplicate the enormous amount of currently
duplicated code between the float and the fixed-point decoder,
one needs common contexts. Given that int and float have the
same size on all common systems, this commit replaces these
arrays by unions of int arrays and of float arrays. The names
of these arrays have been chosen to be compatible with
AAC_RENAME().

sizeof(PredictorState) is different for the floating-point and
the fixed-point AAC decoders; this is an obstacle for deduplicating
code between these decoders. So don't include this array in
SingleChannelElement, instead add a union of pointers to the
fixed-point PredictorState and the floating-point PredictorState.
The actual arrays are part of the extended ChannelElement
to be allocated by ff_aac_sbr_ctx_alloc_init(); it also
sets the pointers.

Up until now, AACDecContext included pointers to one of these
contexts depending upon USE_FIXED. Yet deduplicating
the common parts of the float and fixed-point AAC decoders
needs common structures, so we put both of these pointers
in a union.

The AAC fixed-point and floating-point decoders have
a lot of duplicated code; the main obstacle to
deduplicating it is that several structures with the
same name are actually different types, because
they contain INTFLOATs (int or float) and AAC_FLOATs
(SoftFloat or float). SoftFloat and float typically
have different sizes, so dealing with it is the more
complicated of the two.
AAC_FLOAT is mainly used in the sbr code and structures,
so one can still deduplicate the code by only exposing
the common part of ChannelElement (without SBR context)
to the common decoder part. One prerequisite of this
is to move allocating the whole ChannelElement to
code that will stay unduplicated. It is most natural
to move said allocation to ff_aac_sbr_ctx_init().

Each ChannelElement contains exactly one SpectralBandReplication
structure; the latter structure contains lots of buffers
whose size depend upon USE_FIXED (i.e. AAC_FLOAT arrays).
This complicates deduplicating the parts of the AAC decoder
that are duplicated between the fixed-point and the floating
point decoder.
In order to fix this, the SpectralBandReplication structure
will be moved from the part of ChannelElement visible to
the common code. Therefore the ff_aac_sbr_* functions
are ported to accept a ChannelElement*; they will then have
to translate that to the corresponding SpectralBandReplication*
themselves (which is possible, because there are floating-point
and fixed-point versions of these functions).
While just at it, also ensure that these functions are properly
namespaced.

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.
