In the system to card direction, the DMA block moves data from the host memory to the PL-side through PCIe and then writes the data to PS-DDR via the AXI-MM interface. Then VCU IP reads data from PS-DDR, performs Video encoding/decoding and writes it back to the same memory. Lastly, in card to system direction, DMA reads PS-DDR via the AXI-MM interface and writes to host system memory through PCIe.

Quality: Low bitrate AVC encoding:
Enable
profile=highand useqp-mode=autofor low-bitrate encoding use-cases.The high profile enables 8x8 transform which results in better video quality at low bitrates.
