Side data is to pass data to the decoder. The decoder has no use
of this, so IMHO that is the wrong approach.
It would be closer to metadata, but since those statistics are not
per-stream I'd say they probably should go into the AVFormat context.
But if you want more fine-grained statistics, I guess you could also
make the demuxer export a data-stream with them, that would allow
you to give them time-stamps and finer granularity than per-packet
if you want.
