Adding background filters to your application

The process of adding background filters follows these broad steps:

• Check for supported browsers.

• Create a VideoFxConfig object with the configuration you want to use.

• Use the configuration object to create a VideoFxProcessor object.

• Include the VideoFxProcessor object in a VideoTransformDevice .

• Use the VideoTransformDevice to start the video input.

Note

To complete those steps, you must first:

• Create a Logger.

• Choose a video device of class MediaDeviceInfo.

• Successfully join a MeetingSession.

Steps in the following sections explain how to complete the process.
