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 with the streaming use case where bandwidth plays a vital role.
This design supports the following video interfaces:

...
Uri:
File path or Network URL. Applicable for file playback and stream-in pipeline only. Supported file formats for playback are ts, mp4, and mkv.
Options: file:///media/usb/abc.ts (for file path), udp://192.168.26.89:5004/ (for Network streaming, Here 192.168.26.89 is IP address and 5004 is port nonumber)
Raw:
To tell the pipeline is processed or pass-through.
Options: True, False
...
Stream-in use case: Run the following
gst-launch-1.0command to display stream-in video using the Gstreamer pipeline where5004is port nonumber.
