Here you need to store interleaved_min/max into rtsp_st too, I think I
already told you this in some earlier review?
Right now, receiving more than one stream over TCP is broken.
After fixing this and the other things I mentioned, I was able to receive
streams from both avconv, QuickTime Broadcaster and Wirecast.
