gst-omx: should allocate the same number of buffers on consecutive ports when using dynamic buffer mode
Submitted by Guillaume Desmottes @gdesmott
Link to original bug (#795746)
Description
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.
