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 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

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.
