  If you want to use proprietary codecs/plugins, just ask the provider
of those codecs (I'm pretty sure Fluendo has closed-source vdpau
plugins).

  If you want an open-source solution, there are already plugins in
gst-plugins-bad that wrap VDPAU. Right now only mpeg2 is present, but
Anton (who has been doing that work) just got git commit access, so one
should expect a lot of progress in that regards within the next month or
so.

  Our main concern about VDPAU and VAAPI ... is that those two API rely
on "you shall use our API to do everything", which is a very
narrow-minded view of modern multimedia usage. We need to be able to (1)
only use parts of those API (like only the decoding part) and (2) be
able to efficiently (without bringing back to main memory) use the
decoded content.

   Yours,

     Edward
