One that is fine enough to represent all DV audio sample rates. Audio
packet durations are now sample-accurate.
This largely undoes commit 76fbb0052d. To
avoid breaking the issue fixed by that commit, resync audio timestamps
against video if they get more than one frame apart. The sample from
issue #8762 still works correctly after this commit.
Slightly changes the results of the lavf-dv seektest, due to the audio
timebase being more granular.
Current code will call avpriv_set_pts_info() for each video frame,
possibly setting a different timebase if the stream framerate changes.
This violates API conventions, as the timebase is supposed to stay
constant after stream creation.
Change the demuxer to set a single timebase that is fine enough to
handle all supported DV framerates.
The seek tests change slightly because the new timebase is more
granular.

This allows the usage of codecs in builds that have a parser but no decoders
for remuxing scenarios with raw sources.

Also remove the _minus8 part of the name to be in line with the rest of the
decoder, and fix the storage type for pps_palette_predictor_initializer,
to support hbd values.

Will remove native backend, so change the default backend in filters,
and also remove the python scripts which generate native model file.

Native backend will be removed in following commits, so change the
dnn interface and modify the error message in it first.

Not doing so is an obvious oversight - the ICC profile is tied to the
original colorspace, so if we change it, we should definitely strip this
information.
We should probably also have an extra option to control whether the ICC
profile should be stripped, ignored, or applied, but for now this fixes
an existing bug.
Some testing revealed this to be a very efficient and reliable method of
ingesting GPU frames into libplacebo, so it's a good idea to give as an
example.
This example being first is now misleading because round-tripping
through hwdownload/hwupload is neither required nor recommended. Also,
the comment about avoiding format conversion is unnecessary because
`libplacebo` will now inherit the input frame format by default.
This was a bug/mistake in dae3679a9b.
use_mfra_for by defintion only has an effect on fragmented MP4 files,
making the check not only redundant, but also broken if a user used
the option globally (i.e. set on non-fragmented MP4s).
