Browse source 
Original commit message from CVS:
* gst/matroska/matroska-mux.c:
(gst_matroska_mux_audio_pad_setcaps):
Add support for muxing raw float audio now that the spec defines the
endianness and add support for muxing raw integer audio with 24 and
32 bits.
Allow muxing of more than 8 audio channels.
