The following pipelines were tested using the smartcam firmware, which is based on the kv260_ispMipiRx_vcu_DP Vitis platform provided by Xilinx. This platform doesn't use the Video Mixer for the video out, so we use the display directly.

Network to display
We optimized these pipelines to show the low-latency capabilities of this device.
For the sending pipeline please see the Video Encoding examples.
