The easiest way to know if your videos are playing with GPU acceleration are to watch the process of xplayer, mpv or whatever you are playing. The CPU usage should be no more than 10% for that process/program if it is using acceleration.
Let's manually play with vdpau to make sure it works before we make it permanent:
First make sure you have libvdpau installed:
sudo apt install vdpau-driver-all
If you run mpv and get an error like this it means you are missing libvdpau:
Playing: MVI_0822.MP4
(+) Video --vid=1 (*) (h264)
(+) Audio --aid=1 --alang=eng (*) (aac)
Failed to open VDPAU backend libvdpau_radeonsi.so: cannot open shared object file: No such file or directory
[vo/vdpau] Error when calling vdp_device_create_x11: 1
Error opening/initializing the selected video_out (-vo) device.
Video: no video
AO: [pulse] 48000Hz stereo 2ch float
A: 00:00:08 / 00:01:17 (11%)
To enable AMD VDPAU acceleration in mpv (the successor to mplayer) just add this file to make it permanent:
After making changes to the conf below if you open a video with mpv and only hear sound it means there is an issue with your config. To see any error you can just manually run "mpv video.mp4"
vi ~/.config/mpv/mpv.conf
hwdec=vdpau
vo=vdpau # OR vo=vdpau
#you can also add this to the config file which may produce better quality/looking playback above but be warned it does not seem to work for some older cards like Kabini 8400:
profile=gpu-hq
vdpauinfo is a great way to see what is supported by your GPU acceleration:
sudo apt install vdpauinfo
vdpauinfo
