Comment (by Cigaes):

 Replying to [ticket:5461 andrey.utkin]:
 > If you drop "-auto_convert 0", it works fine, too, but this incurs other
 issues in my use case and thus it's not appropriate workaround.

 Care to elaborate? H.264 in MP4 format can not be concatenated, that is
 one of the many ways the format is braindead. You ''have'' to let concat
 automatically convert.
