Video playback is slow on DB820c

[Ajith_Kumaresh]

Hi,

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.

Regards,
Ajith.

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

How to solve the problem of high CPU usage of 1080p video playback on db410c Debian system

Try the following instead: ffplay -vcodec h264_v4l2m2m -i big_buck_bunny.mp4 For gstreamer you can use the following pipeline for mp4 (with audio): GST_GL_PLATFORM=egl gst-launch-1.0 \ filesrc location=./big_buck_bunny.mp4 ! qtdemux name=m \ m.audio_0 ! queue ! decodebin ! audioconvert ! audioresample ! autoaudiosink \ m.video_0 ! queue ! h264parse ! v4l2h264dec capture-io-mode=dmabuf ! glimagesink or for mkv (with audio): GST_GL_PLATFORM=egl gst-launch-1.0 \ filesrc location=./Panason…

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.
