I added libvdpau as an input to mpv, mplayer, and vlc. Here are the
results.

It seems to have worked for mpv, with ldd reporting a link to the VDPAU
library in the store.

It also seems to work for vlc, although it appears as a plugin in vlc's
store directory rather than a dynamic link.

The mplayer build while compiling the "mencoder" output like this:
libmpcodecs/vd_ffmpeg.o: In function `set_format_params':
vd_ffmpeg.c:(.text+0x601): undefined reference to
`av_alloc_vdpaucontext'
libmpcodecs/vd_ffmpeg.o: In function `update_configuration.isra.2':
vd_ffmpeg.c:(.text+0xcf9): undefined reference to
`av_alloc_vdpaucontext'
collect2: error: ld returned 1 exit status 
Makefile:750: recipe for target 'mencoder' failed
make: *** [mencoder] Error 1
make: *** Waiting for unfinished jobs....

collect2: error: ld returned 1 exit status 
Makefile:750: recipe for target 'mplayer' failed
make: *** [mplayer] Error 1

I can't truly test mpv or vlc because I don't have any hardware that
supports VDPAU. I guess the error message I read a few days wasn't
relevant.
