========================

Comment:
---------
Gstreamer can generate audio raw and convert for file avi, but it can't put
audio raw in mkv file and after convert for file avi.


Test with audiotestsrc :
-----------------------
gst-launch audiotestsrc ! "audio/x-raw-int, width=(int)32, depth=(int)32,
signed=(boolean)true, endianness=(int)1234, channels=(int)2, rate=(int)48000" !
audioconvert  ! avimux ! filesink location=test.avi -v

Generate audio file mkv with the same audio caps :
--------------------------------------------------
gst-launch audiotestsrc ! "audio/x-raw-int, width=(int)32, depth=(int)32,
signed=(boolean)true, endianness=(int)1234, channels=(int)2, rate=(int)48000" !
audioconvert  ! matroskamux ! filesink location=test.mkv -e

Convertion from audio file mkv to audio file avi:
--------------------------------------------------
gst-launch-0.10 filesrc location=test.mkv ! matroskademux name=demux ! queue !
audioconvert ! queue ! avimux bigfile=True name=mux ! progressreport
update-freq=1 silent=true ! filesink location=test.avi -v

Solution for the moment to convert audio file mkv to audio file avi:
---------------------------------------------------------------------
gst-launch-0.10 filesrc location=test.mkv ! matroskademux name=demux ! queue !
audioconvert ! "audio/x-raw-float, width=(int)64, rate=(int)48000,
channels=(int)2, endianness=(int)1234" ! audioconvert ! queue ! avimux
bigfile=True name=mux ! progressreport update-freq=1 silent=true ! filesink
location=test.avi -v
