Hello,
As I don't know much English, I'll try to explain the problem with my VLC.
I have a 4K video (MKV extension) which has a total running time of 1h 32min.
The problem is that when I play this video it stops at 11:46, the image stops but the sound continues. This happens with any 4K video.
I´ve already convert the video to other resolution but is the same.
What could it be?
