Description

When javacv FFmpegFrameGrabber is used for continuous streaming, and the streaming source is switched in real time among multiple short videos (less than 10 seconds), audio and video will be out of sync after a period of time (possibly 40 seconds). How do I set timestamps to synchronize them?

Contributor guide

Research direction
Inspect the timestamp handling in FFmpegFrameGrabber when switching sources. Look at how timestamps are reset or adjusted for new streams.
