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

1.2 Run Flow
The TRD package is released with the source code, Vivado project, Petalinux BSP, and SD card image that enables the user to run the demonstration. It also includes the binaries necessary to configure and boot the ZCU106 board. Prior to running the steps mentioned in this wiki page, download the TRD package and extract its contents to a directory referred to as ‘TRD_HOME' which is the home directory.
Refer below link to download all TRD contents.
TRD package contents specific to HDMI Video Capture design is placed in the following directory structure. The user needs to copy all the files from the $TRD_HOME/images/vcu_hdmirx/ to FAT32 formatted SD card directory.
