question about vdpau and vaapi[solved]

[Adel Ahmed]

I was reading up on vdpau and vaapi in the wiki, I'm not sure everything is clear
#vdpauinfo
display: :0.0 screen: 0
Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory
Error creating VDPAU device: 1
does that mean VDPAU is not supported?
# mplayer2 -vc help | grep --color vdpa
ffmpeg12vdpau ffmpeg working FFmpeg MPEG-1/2 (VDPAU) [mpegvideo_vdpau]
ffwmv3vdpau ffmpeg problems FFmpeg WMV3/WMV9 (VDPAU) [wmv3_vdpau]

localhost media # lspci | grep vga -i

should I disable the vdpau and vaapi flags globally or am I getting this wrong?

thanks

Your Intel chip (or better: the drivers) don't support VDPAU, if you want to have hardware video decoding you will need to use VAAPI instead.

[Adel Ahmed]

hmm ok what about those ffmpeg plugins, are they using vdpau or s/w decoding?

[ivanoff]

Usually ffmpeg is able to take advantage of both vaapi and vdpau.
Since your hardware doesn't support it, you can disable vdpau entirely.
vainfo can tell you if libva (va api) is activated.
When we are at it, if you can make mplayer-vaapi work, I am interested.

what does this tell about my laptop:
vainfo

libva info: va_getDriverName() returns 0

Seems ok, doesn't it ?

I'm not sure I get this yet, does this mean my hardware supports vdpau?

[ivanoff]

No, it means your hardware supports vaapi (libva)
Intel never provided vdpau support, so no hope on that side.
there is a way however to add a crossbridge (add vaapi support to vdpau, very limited) with the following package
http://gpo.zugaina.org/x11-libs/libvdpau-va-gl
but performances were poor, to my mind.
Why do you need vdpau for, anyway ?

I don't need vdpau, I was checking if I should disable it globally

thanks
