Description

I tried running the video player example below but the audio is very out of sync with the video. I tried 2 videos of different formats and both are not in sync.

https://github.com/bytedeco/javacv/blob/master/samples/JavaFxPlayVideoAndAudio.java

Any ideas why this would happen?

I'm on Mac OS 13.6.3.

Contributor guide

Research direction
Check the MediaPlayer synchronization in JavaFX; trace the audio and video timestamps from FFmpeg decoding to JavaFX playback. Ensure the video frames and audio samples are being presented with correct timestamps.
