            Bug ID: 779466
           Summary: v4l2: improve v4l2dec auto-negotiation
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: m.tretter at pengutronix.de
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

Auto-negotiation for decoding videos with the V4L2 decoder results in a
suboptimal pipeline configuration.

The following patches allow to set the decoder framerate based on the framerate
of the encoded video and to auto-select GST_V4L2_IO_DMABUF for capture buffers
if the driver supports it.
