I receive them via IPTV, each camera has its own multicast address and I've done some experiments in order to use avconv + the external recorder option (through a custom script) available in mythtv to make all those independent channels look like a single channel with multiple video streams in it.

I know dvd/blueray playback has some sort of multi-angle support, but I can't find nothing similar regarding recorded TV.

I’ve used VLC for playback of full transport streams, they can have many channels within the same file. VLC allows you to select which channel to watch by name, even decodes subtitles and multiple audio streams. I’ve never found a way to do this with the same file in MythTV.

I do have some multi angle DVDs, I just tried one from an iso file and there’s an angle menu which allows selection of the four video angles, maybe you could mux together the video streams in the same way a multi angle dvd does? Maybe ffmpeg can be persuaded to do this?

I just tried a transport stream with several video channels in it and MythTV just plays the first one and there’s no select video stream menu like the select audio one.
