Zynq UltraScale＋ MPSoC VCU TRD 2019.1 - HDMI Video Capture
...
1 Overview
The primary goal of this Design is to demonstrate the capabilities of VCU hard block present in Zynq UltraScale+ EV devices. The TRD will serve as a platform to tune the performance parameters of VCU and arrive at optimal configurations for encoder and decoder blocks.
This design supports the following video interfaces:
Sources:
- HDMI-Rx capture pipeline implemented in the PL.
Sink:
- Stream-out from network or internet.
- File sink (SD card, USB storage, SATA hard disk).
VCU Codec:
- Video Encode/Decode capability using VCU hard block in PL
- AVC/HEVC encoding.
- Encoder/decoder parameter configuration.
Streaming Interfaces:
- 1G Ethernet PS GEM
Video Format:
- NV12
