Video playback is slow on DB820c


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.


You need to rely on the hardware decoder (via a gst pipeline or using ffmpeg):

4k will not be good without hardware decoder.
1080p30-h264 should be doable in software.
720p30-h265 should also be doable in software.

Hi all,

Thanks for your responses. I will test with hardware decoder.
