Video Player

The Holoscan Sensor Bridge Demo brings examples of two different video players, which run all the process for capture, process and display image.

linux_imx274_player.py

This player is used on NVIDIA Jetson Orin AGX platform. The process used to display image is described below

Operators Descriptions

• Camera: The main capture device, in this case is being use a imx274-dual.
• Receiver Operator: Mechanism to receive the camera MIPI packets. The Roce Receiver uses Remote Direct Memory Access that is a network protocol that enables the exchange data from one device into another to be use directly on user space, which creates a faster and more efficient data transmission. The Linux Receiver is based on the traditional socket-based receiver of Linux.
• CSI to Bayer: Process to convert the MIPI packets form the Camera Serial Interface to Bayer format using Bayer filters.
