VLC

Doesnt VLC support VA-API too?

Is VLC in Archlinux compiled without VA-API Support?

VDPAU vs VAAPI relationship

We have two very similar pages, VDPAU and VA-API, with no clear description of the relationship between VDPAU and VAAPI.

Basically, open source ATI drivers (ati-dri), open source NVIDIA drivers (nouveau-dri) and proprietary NVIDIA drivers (nvidia-utils) support natively VDPAU, whereas the Intel drivers (intel-dri) and proprietary ATI drivers (catalyst-utilsAUR) support natively VAAPI. Then, to fill in the missing support, there is libvdpau-va-gl to use VAAPI as a backend for VDPAU, and libva-vdpau-driver to use VDPAU as a backend for VAAPI.

Assuming this is correct, VDPAU and VA-API should be merged into one article and describe these differences properly. Having two articles on such a similar subject is pretty confusing.

Further, are the last two rows of the table specific only to VA-API or is it possible even with VDPAU?

Yeah I too guess that merging the articles would make things clearer, however how would you name the new article? Some ideas, "Hardware accelerated video processing", "Hardware video acceleration"...
I'm sorry I can't answer your last question.

I was thinking about "Hardware video acceleration"; note that XvMC would also fall into this category, however it is now useful only for very old graphic cards.
I've found no information about encoding with VDPAU, which actually makes sense as it stands for "Video Decode and Presentation API for Unix"...
