Abstract: A method of operating a multimedia player is provided. The method includes decoding an audio stream of the multimedia player and rendering the decoded audio stream in the multimedia player, updating the media time of the media player with an audio timestamp of the rendered audio stream as the audio stream is rendered, and, while decoding and rendering the audio stream, decoding a video stream and checking the media clock to determine if a video timestamp of the decoded video stream is within a threshold of the media clock time, and if not then adapting post-processing of the video stream to decrease video stream post-processing time.
