Hello,
However long this patch is, it is also mostly useless: the standard does
NOT support multiple distinct tref tags. Instead it supports multiple
references for one or zero trefs, which is what FFmpeg already supports.
I will introduce a patch that instead just adds the ability to set the
track reference type and add track references. The side packet API does
not need to change as far as I can see.

Instead of one track reference, allow multiple. In addition, allow
client to explicitly add track references with side packet
AV_PKG_DATA_TRACK_REFERENCES containing AVTrackReferences. MOVTrack's
track references can be manipulated with helper functions
ff_mov_*tref*.
Multiple track references can be useful in particular with timed meta
data tracks, indicating the track is related to multiple other tracks.
This information ends up in ISO media file box 'tref' as specified by
ISO/IEC 14496-12.
