           Summary: v4lsrc: Fails using glimagesink in userptr
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: Normal
         Component: gst-plugins-good

     GNOME version: ---


When building v4l2 plugin in -good without libv4l2, one can start using userptr
IO mode. For UVC camera, it should work with any kind of allocated buffer.
Though, while it works with xvimagesink, it results in random output with
glimagesink, but I don't know yet why.

gst-launch-1.0 v4l2src io-mode=userptr ! glimagesink

While the following works

gst-launch-1.0 v4l2src io-mode=userptr ! xvimagesink
