Issues gstreamer using videomixer

AsomoHo
Hi

I am use command

gst-launch-0.10 v4l2src device=/dev/video0 ! video/x-raw-yuv,width=320,height=240 ! alpha ! queue ! videomixer name=mix ! ffmpegcolorspace ! autovideosink videotestsrc pattern=1 ! video/x-raw-yuv,width=320,height=240 ! videobox left=-320 border-alpha=0 ! queue ! mix.

it's work

try change videotestsrc pattern=1 to v4l2src device=/dev/video1 

I get a the following error.

Setting pipeline to PAUSED ...
libv4l2: error turning on stream: No space left on device
Pipeline is live and does not need PREROLL ...
ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src1: Error starting streaming on device '/dev/video1'.
Additional debug info:
