Every container signals it as such, and the data media stream type is too
undefined and unsupported across the codebase that even if no standalone
decoder can be present for it, it's preferable to it.
This is technically an API break, but LCEVC support has been minimal until
now so it should be safe.

This creates a new codec id for mxf vbi_vanc_smpte_436M streams.
This makes it easier to use from other [de]muxers and bitstream filters.
It's just the data in Table 7 (starts on page 13) of:

IVTV, a Linux driver for TV tuners, and V4L2 utilize
a coding named after IVTV to carry sliced VBI data
in MPEG streams produced by tuner cards with
VBI capture capability and an MPEG-2 encoder SoC.
IVTV or V4L2 driver will transport the coded data into a
MPEG-PS private stream ("IVTV") that can be captured
from the card alongside the video/audio.
The data could include:
EIA-608, Teletext, WSS (PAL widescreen signaling),
or VPS (PAL VCR signaling).

libjxl supports animated encoding, so we add a wrapper to the
library using the receive_packet callback method.
This code was based largely on a patch sent by Zsolt Vadász,
although it was updated to use more recent coding practices
and many of the leaks and issues were fixed.

xHE-AAC is a profile where some frames depend on other key frames, named IPF.
By setting the codec as Intra Only, all frames output by decoders and all
packets output by encoders/demuxers will be unconditionally flaged as
keyframes, which is incorrect.
Should fix ticket #11272.

The LC3 audio codec is the default codec of Bluetooth LE audio.
This is a wrapper over the liblc3 library (https://github.com/google/liblc3).

- Added new entry to codec IDs list
- Added new entry to the codec descriptor list
- Bumped libavcodec minor version
- Added profiles for EVC codec

To support bitmap subtitle output, remove AV_CODEC_PROP_TEXT_SUB
property from codec descriptor for AV_CODEC_ID_ARIB_CAPTION.
This is similar to `libavcodec/libzvbi-teletextdec.c`
(AV_CODEC_ID_DVB_TELETEXT).
Instead, each subtitle decoder has to specify a subtitile format.
`libavcodec/libaribb24.c` uses same AV_CODEC_ID_ARIB_CAPTION and
expects AV_CODEC_PROP_TEXT_SUB to be set, so this adds a line to
specify a format there.
