Video Player

The Holoscan Sensor Bridge Demo brings examples of two different video players, which run all the processes for capturing, processing, and displaying images.

linux_imx274_player.py

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

ISP process for linux_imx274_player.py

imx274_player.py

This player is used on NVIDIA IGX platforms. Where the unique difference is the receiver operator as described below.

Operators Descriptions

• Camera: The main capture device, in this case, is being used as an IMX274-dual.
• Receiver Operator: Mechanism to receive the camera MIPI packets. The Roce Receiver uses Remote Direct Memory Access, which is a network protocol that enables the exchange of data from one device to another to be used directly in 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 from the Camera Serial Interface to Bayer format using Bayer filters.
