YouTube Sound Synch

Sunch.

When watching videos on YouTube (and elsehwhere, but chiefly on YouTube), it sometimes happens that the sound is out of synch with the video. This becomes very annoying.

I think it's probably difficult to automatically fix the synch (maybe some algorithm could track the speaker's mouth and figure it out, but it would probably get it wrong more often than right).

So, I just want two little buttons, to advance or retard the sound relative to the video, in (say) 1/10th of a second increments.

[Prompted by watching an hour-long Feynman lecture, in which the sound slowly drifted by about 3 seconds]

       Brilliant! I'd vote for finer gradation, maybe ~40ms. +

       Wow there's lectures on youtube? I thought it was just music videos and girls twerking.

       Wish I could verify that, but I can't bring myself to search for anything else.

       It should be possible to stream YouTube content with VLC, which can advance or delay the sound in 50ms increments. That would be a kludge, though.

       eminently practical and minus the rant that should accompany it.   

       There are stream-scrapers but they fall over every time YT changes something.   

       Meanwhile, oh look, they made the playback resolution button more fiddly and you still can't tell it not to change resolutions halfway through a playback by default.
