Note: Not a live demo, server configuration is just for example. For live working example try the Millicast Publisher and Subscriber example. Or AWS Kinesis Publisher and Subscriber example.
This example demonstrates GPU accelerating screensharing mixing with camera stream. The camera video will be resized in the foreground with the screenshare as a background texture.
The scaledWidth configuration is a percentage of scaling the video texture to the screen share texture background.
The renderType set to 3 enables screen mixer virtual rendering.
