Script  for muxing  AAC

Using the attached script to encode and mux a PCM file to get an AAC file into
a container, it looks like generated files cannot be played back with common
players.

Plug-ins used: faac, qtmux, gppmux, mp4mux, matroskamux and avimux.

Players tested: VLC 0.8.6e, Windows QuickTime 7.2, Totem 2.22.1, Rhythmbox
0.11.5, mplayer 1.0rc2-4.2.4.

GStreamer versions used are latest released: 0.10.25 for library and -core
plug-ins; 0.10.16 for -good; 0.10.14 for -bad.

Tried Low Complexity AAC audio (both raw and ADTS stream formats), but only the
raw AAC using avi, mov, 3gp and mp4 containers can be played back, and only
with mplayer.

ADTS files show messages like "FAAD: Failed to decode frame: Invalid number of
channels".

Duration of the audio stream seems to be off as reported by MP4Box (from GPAC
0.4.4):
  Track # 1 Info - TrackID 1 - TimeScale 44100 - Duration 37 Days, 22:19:01.870
  Media Info: Language "Undetermined" - Type "soun:mp4a" - 1713 samples
  MPEG-4 Config: Audio Stream - ObjectTypeIndication 0x40
  MPEG-4 Audio AAC LC - 2 Channel(s) - SampleRate 44100
  Self-synchronized

(Files generated using matroskamux do no have anything in them [file size is
around 2K].)
