Learn about the details of the software architecture of the Zynq UltraScale+ MPSoC Video Codec Unit (VCU) Region of Interest (ROI) based encoding reference design. The Xilinx video and connectivity IP support stack is introduced. Then, the software stack for the VCU ROI application is described, with details on the Gstreamer stream-out pipeline, and the ROI GStreamer plug-in. Then, the Gstreamer stream-in pipeline is described. To conclude, resources are presented for getting started with the reference design.

Prior to watching this software architecture video, it is recommended to watch the first video in this series, called "Maximizing broadcast bandwidth: Region of Interest based encoding" to learn how Region Of Interest based encoding addresses the broadcast bandwidth problem.
