I filed a bug report for this a couple of months ago. Myself and another
engineer struggled with this error for a few weeks. This plugin works fine
on GStreamer 0.10. I think that it has something to do with v4l2src on
GStreamer 1.x. I know I saw that there was an open issue that Wim and
others have been struggling to solve. They may be related...
