I know that my graphics card supports it (it’s a GTX469M) and I have installed the nvidia drivers but can’t get vdpau working. In particular, I’d like to have it working in kdenlive, which means ffmpeg. The simplest test I can make AFAIK is mplayer -vo vdpau -vc ffh264vdpau and the result is that if I simply run mplayer with no options, playback is ok whilst the aforementioned, which should be better, is very, very slow (several seconds between frames).
In VLC I enabled the experimental hw acceleration option when it was available but it has disappeared from the menu since and I believe that that is because the packman version lacks it. So any suggestions what I should do? It seems to me that ffmpeg is compiled without it or is it included by default nowadays? Googling yielded results which semed to be out of date.
vainfo results in the following:
libva: libva version 0.31.0
Xlib: extension "XFree86-DRI" missing on display ":0.0".
libva: va_getDriverName() returns 0
libva: Trying to open /usr/lib64/dri/nvidia_drv_video.so
Segmentation fault
I have added videolan to my repositories and changed ffmpeg to those versions as well as installed vdpau-video-nvidia although nothing has required it and I don’t know what it should do since I haven’t noticed any difference.
