摘要： A centralized audio video testing system utilizes a remote client device. The remote client device includes a decoder, a renderer, a media engine, a video capture module and a frame module. The decoder receives a transmitted video stream from a video streaming server and to generate a decoded video stream. The renderer receives the decoded video stream and generates a rendered video stream that is able to be displayed on a display of the remote client device. The media engine receives the rendered video stream and plays the rendered video stream on a media player resident on the remote client device. The video capture module captures frames of the played rendered video stream. The frame manager receives the captured frames of the played rendered video streams and creates a degraded streaming video file.
