1. A method comprising:
determining, by a computing device, a video frame output time associated with a video frame and an audio frame output time associated with an audio frame;
determining, based on the video frame output time and the audio frame output time, a first calculated output delta; and
determining, based on a difference between a first pre-set output delta, for the video frame and the audio frame, and the first calculated output delta satisfying a threshold, an error associated with at least one of the video frame output time or the audio frame output time.
