I make the pipe below:
filesrc location=\"%s\" ! qtdemux name=demux demux.video_0 ! h264parse !
queue ! omxh264dec ! appsink caps=\"%s\" name=testsink"
then I pull a sample from appsink and map its buffer.
I want to send the Appsink sample directly(zero-copy) to our DMA which I
need a physical address to initialize it.
How can I get the physical address of VCU decoder(omxh264dec) output?
Is there any better method to do this?
(I'm working on a Xilinx Zynq ZCU104 board on petalinux)
