[gst-devel] FM radio using v4lsrc

we develop an application receiving FM radio based on GStreamer. But I can't
understand how to create a pipeline with v4lsrc or v4l2src only for radio
signal (without video). I tried
gst-launch -vvv v4l2src device=/dev/radio0 ! decodebin ! pulsesink
in command line at first, but it fails:
(gst-launch-0.10:2489): GLib-WARNING **: g_set_prgname() called multiple
Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Device
'/dev/radio0' is not a capture device.
Additional debug info:
v4l2_calls.c(504): gst_v4l2_open ():
Setting pipeline to NULL ...
Freeing pipeline ...
Could anybody suggest me the right pipeline for FM radio signal processing
or maybe the right parameters for v4lsrc or v4l2src sources?
Thank you very much in advance,
