Virtual Background with Screensharing

Bodypix GPU accelerated virtual background with virtual screenshare

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 dynamic virtual background removal using Bodypix and Tensorflow AI with screenshare switching. When switching to screenshare the screenshare video will be rendered as a GPU background texture, the video will be rendered in the foreground resized.

Backgrounds can be applied using CSS, and bgImage config on the publisher and subscriber. The video element needs to be shown or rendering stops.
