Improved the existing external denoiser in WebRTC: the filter strength is adaptive based on the noise level of the whole frame and the moving object detection result. The adaptive filter effectively removes the artifacts in previous version, such as trailing and blockiness on moving objects. The external denoiser is off by default for now.
