           Summary: dshowvideosrc: Needs filtercaps with Apple FaceTime HD
                    camera
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: Windows
            Status: UNCONFIRMED
          Severity: minor
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gstreamer-bugs at lists.freedesktop.org

With the Apple FaceTime HD camera (in a MacBook Pro Retina Mid-2012), this
simple pipeline results in an error:

gst-launch-1.0 dshowvideosrc device-name="FaceTime HD Camera (Built-in)" !
videoconvert ! autovideosink

gstdshowvideosrc.cpp:665:gst_dshowvideosrc_set_caps: Can't connect
capture filter with fakesink filter (error=0x80070491)

If I specify one of the supported resolutions using filter caps it works fine:
gst-launch-1.0 dshowvideosrc device-name="FaceTime HD Camera (Built-in)" !
video/x-raw,width=640 ! videoconvert ! autovideosink

I tried every supported resolution specifying it in this manner and it worked
fine. I looked around in the caps code for a bit, but didn't find anything
obvious.

With another webcam (Creative Live! VF0400) it works fine, no filter caps are
needed.
