SDL Video Display

Display video on a monitor connected to the NVIDIA target

Since R2020b

Add-On Required: This feature requires the MATLAB Coder Support Package for NVIDIA Jetson and NVIDIA DRIVE Platforms add-on.

  • INVIDIA SDL Video Display block

Libraries:
NVIDIA Jetson and NVIDIA DRIVE / Audio and Video

Description

Display video data using the Simple Directmedia Layer (SDL) multimedia library. A Simulink® model can contain only one SDL Video Display block.

This block takes planar video data in YCbCr 4:2:2 or RGB formats.

Install the Simple DirectMedia Layer (SDL) library on the target. For more information, see Install and Setup Prerequisites for NVIDIA Boards

Parameters

expand all

Specify the format of the input video stream: YCbCr 4:2:2 or RGB.

YCbCr 4:2:2 uses three channels to represent color image data for each pixel:

  • Y is the luma component (essentially a grayscale signal).

  • Cb is the blue-difference chroma component.

  • Cr is the red-difference chroma component.

Cb and Cr are sampled at half the rate of Y. Therefore, if the dimensions of Y are M*N, the dimensions of Cb and Cr are each (M/2) by N.

RGB uses three 8-bit values to represent the red, green, and blue components of each pixel.
