2 raw audio channels then 6

Hi,

audioparse element does not work if the incomming buffers have different number
of channels (and channel layout)

"
WARNING **: Failed to retrieve channel layout from caps. This usually means
there is a GStreamer element that does not implement multichannel audio
correctly. Please file a bug.
"

I join a raw audio file that contains 2 channels then 6.

You can play it using:

A:
gst-launch-0.10 filesrc location=audio.raw ! audioparse rate=48000 channels=2 !
alsasink

B:
gst-launch-0.10 filesrc location=audio.raw ! audioparse rate=48000 channels=6 !
audioconvert ! alsasink

In case A, you can only hear the buffers that are channels 2.
In case B, you can only hear the buffers that are channels 6.


Other question:

Is there a gstreamer muxer that saves buffers and their caps ? (and a caps
demuxer ?) And this way if would be possible to avoid setting fixed properties
as required in the audioparse element ?)
