Creating a VideoFxProcessor object for the Amazon Chime SDK

When creating the VideoFxProcessor object, AWS servers download the runtime assets, or a browser cache loads the assets. If network or CSP configurations prevent access to the assets, the VideoFx.create operation throws an exception. The resulting VideoFxProcessor is configured as a no-op processor, which won’t affect the video stream.

let videoFxProcessor: VideoFxProcessor | undefined = undefined;
try {
  videoFxProcessor = await VideoFxProcessor.create(logger, videoFxConfig);
} catch (error) {
  logger.warn(error.toString());
}

VideoFxProcessor.create also attempts to load the image from backgroundReplacement.backgroundImageURL. If the image fails to load, the processor throws an exception. The processor also throws exceptions for other reasons, such as invalid configurations, unsupported browsers, or underpowered hardware.
