Hello,
I want to do the following in real time : receive a live rtsp stream
(input), copy video & audio stream as is, remux them in a mpeg-ts format,
attach the appropiate PIDs, and finally generate an udp multicast stream
(output).
Ffmpeg command works ok for hours, but suddenly, at random times, the video
and audio (ffplay output) freeze and the ffmpeg command also hang. I have
to press Ctrl+C to stop it and then appeared a line with the ffmpeg
statistics, with no errors.
At this time, when this happen I also have a ping checking the network
connection, but not seems to be a network problem.
I'am attaching the output console of the ffmpeg command :

The same happened in my PC (CentOS 6.7) and my Raspberry (Debian Jessie 8).
I'll appreciate any suggestion.
Thanks a lot in advance.
