Sadly, this vaapi backend is kind of abandon-ware nowadays. Many thinks are
broken right now, such as the GL texture upload and so.

Another option is to use a very recent version of Mesa (or a development one)
where the bridge vdpau-mesa-vaapi is a work in progress.

But, yes, as Tim mentioned, for encoding there's already NVENC if your card
supports it.
