           Summary: Sometimes written file becomes corrupt when multicast
                    stream stops
    Classification: Platform
           Product: GStreamer
           Version: 0.10.34
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal

Last night I have tested the writing to files from 5 cameras simultaneously.
All of them were in mode "RTP over multicast".

After 15 hours of testing I started to replace multicast group addresses from
the camera's web interface (it was the stress test). The write process stopped.
Then I obtained 'totem' player can normally play only 2 of 5 files. For other
files it shows duration of 3 sec and seeking doesn't work.

After launching 'ffmpeg' with key '-vcodec copy' new corrected files plays
normally.

This is the command line used for writing:
'gst-launch-0.10 -v rtspsrc location=rtsp://$1:7070 debug=true latency=0
protocols=0x02 ! rtpjpegdepay ! matroskamux ! filesink location=~/media/$1.mkv'
