 Yes, output file can be played, but it is incorrect:
 - bitrate of output file is 4 kb/s, bitrate of original file is 45 kb/s;
 - duration of output file is 2:58.960, bitrate of original file is
 - timing in output file is not corresponds to timing of original file.

 Even when I try to specify codec and bitrate:

 ffmpeg -i MP4WithAACAudio.mp4 -c:a aac -b:a 64k output.aac

 FFMPEG always creates file with 4 kb/s bitrate:

 Stream #0:0: Audio: aac (LC), 44100 Hz, stereo, fltp, 4 kb/s
