I've been sitting on this for 3 1/2 years now(!), and I finally got
around to fixing the loose ends and convincing myself that it was
correct. It follows the same basic structure as yadif_cuda, including
leaving out the edge handling, to avoid expensive branching.
The contents of this field are not defined for decoding. Use
pkt_timebase, which is the timebase of demuxed packets.
Drop a tautological av_packet_rescale_ts() call, as the stream and
decoder timebases are the same.
Added prerequisites that must be met before providing support for the MPEG-5 EVC codec
- Added new entry to codec IDs list
- Added new entry to the codec descriptor list
- Bumped libavcodec minor version
- Added profiles for EVC codec

0th order modified bessel function of the first kind are used in multiple
places, lets avoid having 3+ different implementations
I picked this one as its accurate and quite fast, it can be replaced if
a better one is found

This algorithm has once again been refactored, this time leading to a
dropping of the old `tone_mapping_mode` field, to be replaced by a
single tunable hybrid mode with configurable strength.
We can approximately map the old modes onto the new API for backwards
compatibility. Replace deprecated enums by their integer equivalents to
safely preserve this API until the next bump.
Upstream deprecated the old ad-hoc, enum/intent-based gamut mapping API
and added a new API based on colorimetrically accurate gamut mapping
functions.
The relevant change for us is the addition of several new modes, as well
as deprecation of the old options. Update the documentation accordingly.
Not only this is information that relies on the concept of a sequence of
frames, which is completely out of place as a field in AVFrame, but there are
no known or intended uses of this field.

For encoding, this field is entirely redundant with
AVCodecContext.framerate.
For decoding, this field is entirely redundant with
AV_CODEC_PROP_FIELDS.
This exposes libplacebo's frame mixing functionality to vf_libplacebo,
by allowing users to specify a desired target fps to output at. Incoming
frames will be smoothly resampled (in a manner determined by the
`frame_mixer` option, to be added in the next commit).
To generate a consistently timed output stream, we directly use the
desired framerate as the timebase, and simply output frames in
sequential order (tracked by the number of frames output so far).
THis filter can correct certain issues seen from upstream sources
where the cc_count is not properly set or the CEA-608 tuples are
not at the start of the payload as expected.
Make use of the ccfifo to extract and immediately repack the CEA-708
side data, thereby removing any extra padding and ensuring the 608
tuples are at the front of the payload.

Commit 55b81528a9 ("doc/filters: itemize crop examples") dropped the
quotation marks from these examples, but this one remained. Quotes are
actually needed to put the example into a command line or a program, but
removing it here makes the example consistent with the document.
