Also it might be worth mentioning that multiple 'tracks' could be stored as chapters using info packets to label them, but if so they obviously need to be timed one after another rather than all starting at time=0.
Different content (compared to different viewpoints/encodings) of something should not overlap timewise to begin with. If thats unclear it should be clarified! (I assume you are thinking of recording several radio stations or something like that, IMHO that should be done to seperate files or the result should be remuxed at the end)
I guess this means NUT is not intended to be used in typical broadcast environments where each channel has far more bandwidth than a single program requires. This is why MPEG-TS supports multiple independent programs.
There's nothing keeping you from partitioning a physical channel via a separate protocol layer. For example, a DSL line has far more bandwidth than needed to watch youtube, but that doesn't mean that html, email, etc. is interleaved into the FLV container!! Rather, you have TCP for multiplex unrelated connections over a single physical network line. The same principle applies to broadcast channels as well. There is no excuse for container/transport incest!!!!!
Thats all nice and well, just that the reason why nut cant be used directly is because of maybe 2-3 lines in the spec. And as solution you suggest an additional protocol layer. Which is equivalent to double layer muxing. Which actually violates the spec ... And which i then have to somehow support in ffmpeg in addition to mpeg-ts and everything else that implements things the other way around. Well i wont implement it. Feel free to send a patch, but expect me to reject it if its 1000+ lines.
