            Bug ID: 795746
           Summary: gst-omx: should allocate the same number of buffers on
                    consecutive ports when using dynamic buffer mode
    Classification: Platform
           Product: GStreamer
           Version: unspecified
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: Normal
         Component: gst-omx
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: gdesmott at gnome.org
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

On the Zynq, when using dynamic mode (including dma import), let's say we have
"A ! B" with A's output port requiring N buffers and B's input port requiring M
buffers. To prevent starvation, as buffers from A will be kept by B, we should
ensure that both ports have N+M buffers allocated.
