Description
ffmpeg AAC codec (decoder) doesn't seem to support AAC-LD and libfaad or libfaad2 (which is documented to support AAC-LD) is no longer an audio codec option. So there is no way to decode AAC-LD format audio track anymore. However, vlc on windows seems to play the file
ffmpeg build from git snapshot of a few days ago( ffmpeg-HEAD-e16665b) on Fedora 2.6.30.9-96.fc11.x86_6411.
command line:
ffmpeg -y -i po_arrive...mov -acodec pcm_s24le extracted.wav
Error message is:
[aac @ 0x1e9bfa0] Audio object type 23 is not supported.

The sample you uploaded doesn't work, use qt-faststart to produce a sample that you can cut with dd.

Hi
This AAC-LD profile can be achieved using libfdk_aac encoder with FFmpeg:-
$ ffmpeg -i foo -c:a libfdk_aac -profile:a aac_ld -b:a 64k -ar 44100 -ac 2 foo.m4a
Sample is attached.
