Summary of the bug:
I use the dvblast to generate UDP streams for the input of ffmpeg. When
the ffmpeg starts to transcode, it is very stable and normal. But, I don't
know what exactly time the video become cross green lines on the video. It
can't no longer return to normal.

How to reproduce:
I don't know how can reproduce this. When I restart the ffmpeg process, it
returns to normal.
But, I upload the input file(generated by dvblast, recorded by vlc) and
the output file(HLS format, generated by ffmpeg via the below command) to
the ftp. In addition, a complete console output also on the ftp(about
283MB).
And, the input file and the output file is not the same program segment,
but they are also in the period in problem in the case.
I have uploaded files to the ftp server.
input: 1403781705_input_small.ts
output: 0800200c9a66.m3u8, 0800200c9a66[24-47].ts
complete console output: 1403781705_complete_Output_Log.log
The command:

After I tested it, the result is file input + x264, OK file input + mpeg2video, OK udp input + x264, OK udp input + mpeg2video, OK But at the problem time, I use the VLC player to watch the video which generated by dvblast is normal. It's strange. -- Ticket URL: https://trac.ffmpeg.org/ticket/3744#comment:4 FFmpeg https://ffmpeg.org FFmpeg issue tracker ___ FFmpeg-trac mailing list FFmpeg-trac@avcodec.org http://avcodec.org/mailman/listinfo/ffmpeg-trac

At that time time, I killed that ffmpeg process, and I restarted the ffmpeg, the video output become normal.
