Techniques for evaluating media player performance are described. A particular implementation supplies media to a media player where the media includes a video component which has a waveform that alternates between a first video state and a second video state, and an audio component which has a waveform that alternates between a first audio state and a second audio state. In the supplied media the audio and video components are temporally synchronized in transition between respective first and second states. The process further analyzes corresponding output from the media player to determine an extent to which the audio and video components are temporally unsynchronized.
