 Summary of the bug: ffmpeg crash after creating m4a file but with mp3
 extension using "-f mp4". the reason to have mp3 filename for m4a codec is
 to avoid an issue with android player seek function.

 How to reproduce:
 % ffmpeg-libfdk -i 001.rm -map_metadata -1 -c:a libfdk_aac -vbr 1
 -movflags frag_keyframe+faststart -af aresample=async=1000 -f mp4 001.mp3
