AVPlay

A UI for synchronized playback of video files with audio.

An app with standard controls for synchronized playback of video files with audio. Framewise processing of video, and global processing of audio, are facilitated. Drag a marker to scrub through the video on a timeline; plot the audio signal.

Note that synchronization is enforced by playing time-stamped frames one at a time. If the processing is expensive, the audio or video may become choppy--but will stay in sync.

This environment may be useful (with modest modifications) for synchronous analysis or visualization of other types of signals.
