 Summary of the bug:

 When streaming some Mjpeg sources ffmpeg (ffplay) may read an EOF as end
 of stream, when actually it's just the end of a frame.

 When playing a stream in ffplay, it will play for some time (a minute or
 so) then the video will stop but ffplay goes on even though the video has
 stopped.

 How to reproduce:

 Run the following command, it will play the stream.
 {{{

 After ~150 seconds, ffplay will continue, but the video output will stop.

 I can reproduce it with the above stream every time.
