I am testing 4k video playback in Debian, kernel - 4.14.96, the video playback is very slow.
I am using the following command to play videos.
$ gst-pay-1.0 filename.mkv --videosink glimagesink
I checked 1080p 60fps and 30fps videos that also slow.
Cay someone please give me some pointers to solve this issue.
