gstreamer-properties-Message: Skipping unavailable plugin 'sunaudiosrc' libv4l2: error turning on stream: No such device gstreamer-properties-Message: Error running pipeline 'Video for Linux 2 (v4l2)': Error starting streaming on device '/dev/video1'. [gstv4l2object.c(2143): gst_v4l2_object_start_streaming (): /GstPipeline:pipeline0/GstV4l2Src:v4l2src1: system error: No such device] I did try plugging and unplugging...at one stage (before a kernel upgrade - forget which one) it did work. This camera worked perfectly on this machine under 10.10 and earlier. from cheese started in the terminal.
