A communication device and associated systems and methods accurately measure amounts by which audio and video playback for a communication become unsynchronized and automatically synchronized the playback based on the measurements. The communication device receives a video stream and an audio stream of the communication with a synchronization signal. The communication device decodes video frames and a unique frame identifier for each video frame from the video stream, an decodes an audio signal from the audio stream. The communication device detects the unique frame identifier of a particular video frame that is played back at a same time at which the audio signal satisfies a threshold, and measures a synchronization offset between the audio and video playback based on a difference between the unique frame identifier of the particular video frame and the unique frame identifier of a different video frame that is identified in the synchronization signal.
A computer-implemented method for measuring audio and video synchronization in a communication, the computer-implemented method comprising:
A system for measuring audio and video synchronization in a communication, the system comprising:
A non-transitory computer-readable medium storing program instructions that, when executed by one or more hardware processors of a communication device, cause the communication device to perform operations comprising:
