 Summary of the bug:
 Hello.  I have a rather complex Project: I have several mkv files which I
 need to convert to mp4.  On the other hand I have a series of jpg files
 that I need to concatenate with all mp4 files, therefore I'm converting
 them to mp4.
 Once I have all mp4 files I create a list as concat syntax requests.
 Summary:
 1. Convert every mkv file to mp4
 2. Convert every jpg file to mp4
 3. Concat all files.
 I'm watching result file and it stops or shows nothing even though player
 is showing timer moving.
 How to reproduce:
 {{{
 ffmpeg -i source.mkv -vcodec copy -acodec copy destination.mp4
 ffmpeg -report -loop 1 -i image.jpg -c:v libx264 -t image.mp4 -vf
 \"fps=7,format=yuv420p\" {1}.mp4
 ffmpeg -report -f concat -i list.txt -c copy results.mp4

 ffmpeg versión N-76456-g6df2c94
 built on with gcc 5.2.0 (GCC)
 }}}
