           Summary: [v4l2src] Fails to negotiate capabilities with Macbook
                    Pro isight
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: mjg59-gnomebugzilla at srcf.ucam.org

Running 

gst-launch-0.10 v4l2src !
video/x-raw-yuv,format=\(fourcc\)UYVY,width=320,height=240 ! ffmpegcolorspace !
ximagesink

gives me a failure to negotiate capabilities error. Reverting 

http://webcvs.freedesktop.org/gstreamer/gst-plugins-good/sys/v4l2/gstv4l2src.c?r1=1.80&r2=1.81

makes it work again. Restoring the old code path to gst_v4l2src_get_caps is
sufficient, so I'm assuming that there's some breakage in how the caps are set
up. I'm using the driver from
http://files.i-nz.net/projects/linux-kernel/isight/uvcvideo-isight.tar.gz -
I'll try to dump the caps from the two versions now.
