user24906: I've got a 10-minute long mp4 file which plays just fine with VLC. Apple Quicktime however plays only the first 6.5 seconds, stops and can't be convinced to jump past that.
Similarly, when I try transcoding it with ffmpeg, it stops at precisely frame 336.
I have figured out the following: when I run ffmpeg with 'loglevel 48' it tells me that there's something called an 'EDIT LIST' inside the file which tells it to drop all frames beyond 336:
ffmpeg -i VIDEO.mp4 -t 20 -pix_fmt yuv420p -c:v rawvideo -loglevel 48 output.avi  
(...) 
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x5617d7c1a880] Processing st: 0, edit list 0 - media time: 0, duration: 6719

Question: is there a way to tell ffmpeg to ignore this EDIT LIST and carry on regardless?

user1871: Yes, there's a private option for the MOV demuxer.
ffmpeg -ignore_editlist 1 -i VIDEO.mp4 ...
