Ugly workaround for libfdk_aac HE:
{{{
$ ffmpeg -v quiet -i BigBuckBunny_640x360.m4v -af atrim=start=0.114694
-c:a libfdk_aac -profile:a aac_he -b:a 64
k test.mp4
$ ffprobe -v quiet -show_entries format=start_time,duration test.mp4
[FORMAT]
start_time=0.000000
duration=596.500000
[/FORMAT]
$ ffprobe -v quiet -show_entries stream=start_time,duration test.mp4
[STREAM]
start_time=0.000000
duration=596.500000
[/STREAM]
[STREAM]
start_time=0.000000
duration=596.474195
[/STREAM]
$ ffmpeg -version
