Are these useful as inputs to programs like VLC and mplayer?

I would have to double-check, but libvdpau is the upstream name for vdpau,
and I'm pretty sure it would go in as a (propagated-?)input for vlc, mplayer
and mpv.

I think they would be native-inputs for vlc, mplayer, and mpv, because
those programs are written (mostly) in C and C++, and so we can provide
the path to the store directory at compile-time.

I added libvdpau as a native-input to each and they build, but I don't
know how to test if the compilation is using libvdpau and using it
correctly.

But I do know that I could not play some video the other day with my
Guix-provided vlc due to some error about VDPAU ;)

Any thoughts?

No, they should be normal inputs - they should be compiled for the target
architecture where the binary is supposed to be run. The binaries themselves
will link dynamically to the libraries.

You could search for it in the build log, in particular during the configure
phase. And you could run "ldd" on the resulting binary and check whether
the libraries appear.

Sorry, I meant to write inputs.

Okay, I'll try that.

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....
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

collect2: error: ld returned 1 exit status 
Makefile:750: recipe for target 'mplayer' failed
make: *** [mplayer] Error 1
phase `build' failed after 32.3 seconds

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.

here's what I got on mpv with vdpau as an input:

I should mention I called this as
$mpv video.mp4 --vo=vdpau, not that it was a random no-video. When I ran it
without --vo=vdpau everything ran as normal, so no regression at least on my
system with vdpau as an input.
