Comment (by isasi):

 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
