 Summary of the bug:

 Sometimes when I stream different MPEGTS streams to FFPlay it cannot play
 some of the streams. This does not happen very often. I have one set TS
 streams that when I stream them one after another to FFPlay it is not able
 to handle the second stream. If I restart FFPlay it will handle the stream
 until the second stream starts again. VLC does not have this issue. I will
 upload the streams after the ticket is created.

 How to reproduce:
