Description Chris Denice 2017-01-13 13:52:51 CET

Just tested mpv under current Cauldon. On the command line, mpv fails opening nvidia driver with this message:


mpv biaggi.avi
Auto-loading profile 'vo.vaapi'
'vo' auto profiles are deprecated.
Playing: biaggi.avi
 (+) Video --vid=1 (indeo3)
 (+) Audio --aid=1 (adpcm_ms)
libva info: VA-API version 0.39.4
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib64/dri/nvidia_drv_video.so
libva info: va_openDriver() returns -1
[vaapi] vaInitialize(): unknown libva error


Indeed, the nvidia driver is not located in /usr/lib64/dri.
It seems to be located there:
/usr/lib64/nvidia-current/xorg/nvidia_drv.so


Cheers,
Chris.

You are wrong : libva tries to open a VAAPI nvidia driver that does not exist at the moment.

You must use VDPAU to use proprietary nvidia hardware acceleration.

mpv --hwdec=vdpau --vo=vdpau biaggi.avi

Status: NEW => RESOLVED
Resolution: (none) => INVALID

Ok, thanks for the info. But I did not do anything else than trying it.

Why is it the default then if the driver does not exist yet?

The default is to use vaapi, as with all intel hardware since sandybridge you have a driver. Then it should try vdpau, and at least software decoding.

I see, these messages are just warnings then, and most likely the vdpau nvidia driver is actually used.

Sorry for the noise!

cheers.
