            Bug ID: 797105
           Summary: v4l2object: Should read the pixel aspect ratio in
                    gst_v4l2_object_acquire_format()
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good

     GNOME version: ---

The pixel aspect ratio is read at probe time using CROPCAP. Though, for m2m
decoder, the PAR is only known after the headers has been processed by the
driver. For this reason, gst_v4l2_object_acquire_format(), which reads the
format returned by the driver, should also read the CROPCAP.
