Hi Nicholas
But that's also not true - it now works as before after switching the settings under
"General" -> "Video" -> "Output driver"
from "vaapi" to "libmpv" - that's all!
I only use smplayer because of the comfortable way to zap between different channels.
So with using "libmpv" I have definitely higher CPU-load (~12%) compared to mpv using
vaapi (~1-2%)., but that's no issue for me.
First of all many thanks for the hint to look for SMPlayer settings which led to get
it working by changing "Output driver".
Further investigating the configuration also led to a solution for the higher CPU load:
SMPlayer seems not to evaluate my $HOME/.config/mpv/mpv.conf where I have hardware accelleration enabled.
I now have set it additionally in SMPlayers configuration under
Setting-> Advanced -> Mplayer/mpv -> Options
--hwdec=vaapi
(Attention: different to mpv.conf the option needs to be prefixed with 2 dashes)
This way CPU load in SMPlayer drops down to only 1-2% - precisely as in MPV native.
Also logs of smplayer are similar to mpv native:
AO: [pipewire] 48000Hz stereo 2ch floatp
VO: [gpu] 1280x720 vaapi[nv12]
INFO_VIDEO_DSIZE=1280x720
MPV_VERSION=mpv 0.35.1
You can monitor GPU usage with the tool "intel-gpu-top" from the Debian-repo.
Watch the ENGINE "Video". Any output !0 indicates hardware decoding.
Also my first setting for "Video" -> "Output driver" may be changed back to "Default".
That gives the same result, also other selections work, i.e. "gpu" but not all enable
HW-decoding. Just "vaapi" throws errors.
Sorry for using this bug report to describe configuration hints for SMPlayer,
but such informnation is hardly available in the web.
Thanks,
Alf
