The amount of tiles does not necessarely need to match the amount of streams referenced
in the grid, as there could be duplicates.
Don't silently ignore EEXIST return codes from avformat_stream_group_add_stream() and
instead store the index of the duplicate stream.

A new codec ID has been added to avcodec for animated JPEG XL, so
we should use that in the animated JPEG XL demuxer.

Layouts with both pairs (7.1, 7.1.2, etc) in IAMF that follow the definition in
ITU-R BS.2051-3 for Systems I and J also follow its ordering. This means side
comes before back, which is the inverse of how it's defined in AVChannel.
To workaround this without having to use custom order channel layouts, swap the
stream ids in the input IAMF structure, so packets for one are mapped to the
other.

Based on enhanced-rtmp v2 spec published by Veovera:
https://veovera.github.io/enhanced-rtmp/docs/enhanced/enhanced-rtmp-v2
This implementation maintains some backwards compatibility by only
writing the track information for track indices > 0. This means that
older FFmpeg versions - and possibly other software - can still read the
first video track properly and skip over unsupported packets.

After introduction of ff_dvdclut_palette_extradata_cat() to convert
DVD subtitle palettes from YUV to RGB, a leak is introduced because
of the call to ff_alloc_extradata(). This is not necessary, instead
we should free the extradata because ff_bprint_to_codecpar_extradata()
will finalize the bprint'ed string to the codecpar and set the length.
Fixes leak introduced in 3b0e6c0ecc.
