openvela-robot 7fab1ff87c avio: Allow custom IO users to get labels for the output bytestream 
This allows callers with avio write callbacks to get the bytestream
positions that correspond to keyframes, suitable for live streaming.

In the simplest form, a caller could expect that a header is written
to the bytestream during the avformat_write_header, and the data
output to the avio context during e.g. av_write_frame corresponds
exactly to the current packet passed in.

When combined with av_interleaved_write_frame, and with muxers that
do buffering (most muxers that do some sort of fragmenting or
clustering), the mapping from input data to bytestream positions
is nontrivial.

This allows callers to get directly information about what part
of the bytestream is what, without having to resort to assumptions
about the muxer behaviour.

One keyframe/fragment/block can still be split into multiple (if
they are larger than the aviocontext buffer), which would call
the callback with e.g. AVIO_DATA_MARKER_SYNC_POINT, followed by
AVIO_DATA_MARKER_UNKNOWN for the second time it is called with
the following data.

openvela-robot 1cb0ff5513 h2645_parse: support badly muxed mp4 streams 
Some streams contain an additional AnnexB NAL inside the mp4/nalff NALU.
This commonly occurs in interlaced streams where both fields are packed
into the same MP4 NAL with an AnnexB startcode in between.

Port handling of this format from the previous h264 nal handling.
