[FFmpeg-devel] get "internal error, slice end before start" message when playing xvid video for udp

[xie you]

Hi all,

When I used ffplay playing an xvid video from udp port (ffplay
udp://?localport=1234), sometimes (not always) the ffplay can not
display the video and I got following error messages . I used vlc as
the streamer, the start command is "vlc filename.avi --sout
'#std{access=udp,mux=ts,dst=localhost:1234}' --loop".
Is this a bug of ffplay or mpeg4 decoder?

The error messages are:
