FAAC output incompatible with iTunes

Jeffrey Barish
I rip a cd to aac using faac with

cdparanoiasrc ! audioconvert ! faac ! ffmux_mp4 ! filesink

(in a program, though, not using gst-launch

I can play the result using GStreamer or Nero, but iTunes doesn't recognize
the file.  Can anyone enlighten me?

Re: FAAC output incompatible with iTunes

faac's default AAC profile (see profile property) is MAIN, whereas IIRC
iTunes/Quicktime player has more of a taste for LC (low complexity).
Also, as strange (un-spec-wise) as it may seem/sound, it appears that iTunes
places inordinate importance to file extension, i.e. it may screw up with .m4a
extension but not so with .mov or .mp4 (QuickTime player does not seem to mind
either way).

So, try one or more of the following:
* LC profile
* other file extension
* recently -bad added qtmux/mp4mux

Mark.

Changing to LC profile and using .m4a extension works.  Thanks for the
suggestions.
