           Summary: libav :0::[00m header damaged         endless message
           Product: Libav
           Version: git HEAD
          Platform: X86
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: Normal
         Component: libavcodec
        AssignedTo: bugzilla at libav.org
        ReportedBy: frank.huber at barco.com


There is a mpeg4 multicast stream with resolution change.
It changes the resolution from 720x576 to 720x288 and back to 720x576.
The stream runs in a loop.
The playback stops at the end of the stream (but it should start again from
beginning).
Stopping and restarting the pipe works every time.

With Debug enabled there are endless printouts:

There is only a pcab file for reproducing. See attachment.

Pipe to check this issue:
gst-launch-1.0 uridecodebin
uri="rtp://226.255.0.14:50010/mpeg4/1/media.amp?protocols=2" ! decodebin !
vaapisink

libav version: 1.2.2

Is this a normal behavior?
