Comment (by cehoyos):

 Replying to [comment:21 superware]:
 > Let me explain from the beginning. I have a "black box" generating live
 h264 over UDP stream, but once in a while, ffmpeg seems to enter a
 situation where it unexpectedly stops outputting frames, without recovery.
 The only solution in that point is to restart playback/ffmpeg

 But wireshark or whatever smart tool you are using must be able to record
 that exact stream and {{{mplayer -dumpstream}}} or {{{aviocat}}} can
 produce a transport stream from it if you restream it or do I miss
 something?
