Can any one here tell me why this pipeline does not work? 

gst-launch-0.10 v4l2src ! queue ! ffmpegcolorspace ! ffenc_flv ! queue !
ffmux_flv name=mux alsasrc device=hw:1 ! queue ! audioconvert ! lame ! queue
!  mux. mux. ! filesink location=vid.flv

Here is the output i get from above:
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstAudioSrcClock
ERROR: from element /GstPipeline:pipeline0/GstAlsaSrc:alsasrc0: Internal
data flow error.
Additional debug info:
gstbasesrc.c(2334): gst_base_src_loop ():
/GstPipeline:pipeline0/GstAlsaSrc:alsasrc0:
streaming task paused, reason not-negotiated (-4)
Execution ended after 37319285 ns.
Setting pipeline to PAUSED ...
Setting pipeline to READY ...
Setting pipeline to NULL ...
Freeing pipeline ...


Funny thing is that if i change the device from hw:1 to hw:0 it works. Also
this pipeline below DOES work.

gst-launch-0.10 v4l2src ! queue ! xvimagesink . alsasrc device=hw:1 !
alsasink

Any one have any ideas?
