Were you able to find a solution for this? This seemed to be have worked well with bravobit library..

The problem seems to be that MP4 containers do not support the amr_nb codec.

To fix this we just re-encoded the audio of the file using the -acodec aac flag instead of -acodec copy. Mind you the flag can also be written as the aliased versions -c:a aac and -c:a copy
