I'm trying to test celtenc/dec with jackaudiosrc/sink, so I have one pipeline
as follows:
GST_DEBUG=2 gst-launch -v jackaudiosrc ! audio/x-raw-float, channels=2 !
audioconvert ! celtenc ! celtdec ! audioconvert ! jackaudiosink

I have another pipeline to produce a test sound:
gst-launch -v audiotestsrc ! jackaudiosink

I connect the testsrc pipeline to the celt pipeline in jack. The celt pipeline
should have the testsrc at its output, but it is only producing silence. Here's
the output from the celt pipeline:

I haven't had better luck with alsa. The line that struck me as suspicious in
the output was:
gstceltenc.c:931:gst_celt_enc_chain:<celtenc0> Buffer is older than previous
timestamp + duration (0:00:00.000000000< 0:00:00.001333333), cannot handle.
Clipping buffer.

Note that i have celt 0.7 installed, and that i'm using gst-plugins-bad-0.10.17
Any thoughts?
