Hi,
with current CVS (and before) it's impossible to mux audio/x-raw-int into
matroska files. MP3 at least works fine.

test file:
gst-launch audiotestsrc num-buffers=500 ! audioconvert !
"audio/x-raw-int,width=16,depth=16,channels=1,rate=44100,signed=(boolean)true,endianess=1234"
! wavenc ! filesink location=test.wav

tested pipeline:
gst-launch -v filesrc location=test.wav ! wavparse ! audioconvert ! matroskamux
! filesink location=test.mkv


IMHO most interesting line when running with GST_DEBUG=5:
0:00:01.262713000  9237 0x1009c748 DEBUG             GST_CAPS
gstpad.c:2365:gst_pad_set_caps:<matroskamux0:audio_0> caps audio/x-raw-int,
endianness=(int)1234, channels=(int)1, width=(int)16, depth=(int)16,
signed=(boolean)true, rate=(int)44100 could not be set


If someone wants the complete output just ask... but I guess it's not necessary
as this is easily reproduced. Changing of the format of the test file with the
capsfilter did not make it work for me, I tested some random variants.

I didn't find anything suspicious in the audio setcaps function of matroskamux
that could reject the above caps.



Bye
