 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:
 {{{

 The console output(segment, due to complete console output about 259MB):
