Please note this a very old version of GStreamer. Unsupported nowadays.

That's because it's the only vdpau decoder implemented in GStreamer. Still,
it is unmaintained, AFAIK.

Hardware accelerated decoders in libva are not wrappable in GStreamer.

Nowadays, VDPAU is considered deprecated and superseded by NVDEC, and GStreamer
has already an implementation of it, though I don't know if your card supports
it.
