This video has an edit list with duration "0", which means we should play for "0" seconds, so ffmpeg won't output any video packets. This is in line with Quicktime player behavior. If you play the file with Quicktime the video won't play, just the audio.

I am guessing the conversion fails because in the encoding process, while interleaving audio and video, audio packets are queued until a video packet appears, but since the demuxer doesn't output any video packets, too many packets are buffered.

Even if conversion succeeds, the output won't have any video which is not what you want I guess. This is similar to many other bugs . Please see https://trac.ffmpeg.org/ticket/6138#comment:7 . You can use -advanced_editlist=0 (which avoids parsing edit lists) to play this file .

hello isasi, but in the video track header atom with duration "16375[00:00:27]", why not use this duration or compatible with it?

if I'm use "-ignore_editlist 1" option for input file, it convert success.

ffmpeg -ignore_editlist 1 -i 0c490b1e-3342-4b00-a33e-1ce5ae26af21.mp4 -y test.mp4
