First explain what stream relations you are talking about and vs. what
other non relations it has to be distinguished from.
We have AVProgram to seperate unrelated stream bundles. We have
disposition, language, codec.bitrate/width/height/sample_rate/CODEC_TYPE_*
to seperate the streams within such a stream bundle.
Comments welcome of course.

Thouse who are best at talking, realize last or never when they are wrong.
