I was analyzing startup time of live multicasts in XBMC, when I found 
some time being spent in avformat_find_stream_info.
Then I started digging into ffprobe, because it uses this method too and 
ended up digging into the complete data flow in ffmpeg from udp_read to 
But I fail to understand all the things going on and just thought asking 
here how to debug would be a good start.

So it's quite an edge case, I cannot promise that any of my work is 
accepted here.
