Problem with 4K video playback

Postby hanky » 16 Dec 2016 16:54

I'm using VLC media player 2.2.2 Weatherwax on Centos 7 x64 and having problem with a 4K video playback. VLC playe lags heavily and almost freezes when playing the video file, although ffplay does not have any problems with it. Also I have the same problem on Windows with VLC player 2.1.3 and 2.2.4.

My video file:

Re: Problem with 4K video playback

It seems that '--avcodec-threads 20' option solves the problem. The solution is found here: https://wiki.videolan.org/WindowsFAQ-2. ... r_laggy.29

Is it intended behaviour that I have to set that option manually?
