Problem with VLC

I created a video file with vokoscreenng installed from the osnap store, video codec used: h264, mp4 format. When I open the video with VLC, I see all black, if I open it with Totem I see everything normally. Checking in the logs:

VLC has a lot of mistakes

I have used various video players, but the most difficult is to work with VLC. It is a top-rated video player with support for multiple formats, but the problem is that it works very poorly with large files. For example, I tried to play some big video in mp4 format, but it didn’t start. So, in the end, I decided to try compressing mp4 files using Movavi Video Converter, and it turned out to be much more convenient. Read more about this software here.
