Yeah, it seems vdpau as API only accelerate those (+may be something recently added):

I think va-api can accelerate vp8/vp9/mjpeg (some variants)
https://cgit.freedesktop.org/mesa/mesa/tree/src/gallium/state_trackers/va
as you can see for open-source drivers based on gallium framework (radeonsi as most advanced example)
acceleration supported for mpeg1/2,h264,hevc(h265),vc1,vp9,mjpeg
I sadly can't test new acceleration because reverse-engineered Nouveau driver for my card (nv92 GeForce 8800)
simply leaves default clocks for video decoding engines (and changig clocks on this generation of GPUs and newest ones is not simple)
So, I can only see slideshow with va-api and mpeg2 file:

I run into small problem during compilation, because libva was installed in non-standard location
(/usr/X11R7/lib) , but then adding symlink to /usr/includes from /usr/X11R7/includes/va fixed configure
and another small hack fixed linking:
