 I was able to reproduce the problem with ffmpeg versions up to 2.5.

 Doesn't work with ffmpeg -i either.

 I'm not sure why ffmpeg needs to go through mpegts.c and more particularly
 mpegts_resync function: since this is a simple image file, I believe there
 should be no need to sync anything.

 I think the image is correct though since I can open it with other
 software (GIMP, etc.) without any error.
