[Libav-user] Custom data in AVPacket or AVFrame

[laddoe]

At first I thought it would be possible to do it per frame, so I tried AVFrameSideData and the av_frame_set_data. Then I thought to try it on a packet with AVPacketSideData. But none of this worked.

It might make a difference to what decoder gets chosen.

What have you tried? If nothing, you probably should test next. You should be
able to see your results in the bitstream file on encoding (e.g. by searching
for your UUID in a hex editor), which allows you to check your development.
