Does anyone know the best way to use FFMPEG to check if a video stream (HLS, etc.) is out of sync with audio?

Thanks in advance

Or you can stop being an autist and play it

There is audio.

And there is video.

Only a human can discern if the audio and video play at the right times.

I want to do it programmatically. There has to be a way.

You don't seem to understand how audio desync happens

Then brush up on machine learning.

This. Also shit fucking sucks when it happens, no programs can correct it. You literally have to sync it with your own ears and eyes.

Wtf? I fail to see how ML would be applicable here..
>>
>>55332470
tl;dr there is no way of telling when audio is desynced without watching the video and the only way to do it programatically would be to teach the computer to recognize it

Probably can't be done.

The only chance you'd have is with something like an MPEG-TS which keeps timestamps, but the program is likely to correct it automatically when you play it.
