Interesting, probably a bug in the r600 gallium driver then. Mpv with
--hwdec=vdpau-copy (instead of --hwdec=vdpau) seems to work for me as well.
Maybe VLC also uses that method.

So far I've built Mesa git versions

84012262ea70435507d3b88ddbc0f621781ec275 (Tue Mar 21 23:15:05 2017 +0100)
566f2ed5716297ce60ca10c57aeddc406835c430 (Fri Apr 14 23:39:15 2017 +0200)
9db9b2e8cd0a0d250c6251a2fef17198616519e7 (Wed May 3 18:37:28 2017 +0200)

and they all work with Kodi and VDPAU.

The blue screen in mpv could be a bug in mpv 0.25 or Mesa still. My guess is
mpv because never had that problem with mpv 0.14 from Ubuntu repository.

I have this same problem but in r600g since 2017-05-17, my report in mpv:
https://github.com/mpv-player/mpv/issues/4433

In my case, the issue only manifest using: 'mpv --vo=opengl --hwdec=vdpau'

I think this other issue is also related:
https://github.com/mpv-player/mpv/issues/4430

--- Comment #7 from joeri.exelm...@gmail.com ---
I used this guide (https://pkg-xorg.alioth.debian.org/howto/build-mesa.html) to
 build the mesa project with git version
84012262ea70435507d3b88ddbc0f621781ec275 (Mar 21 2017), and I can use VDPAU
again in Kodi.

The configure command that I used:
./configure --enable-vdpau --enable-va --with-gallium-drivers=r600
--with-dri-drivers=radeon --enable-llvm --enable-dri3
--with-llvm-prefix=/usr/lib/llvm-4.0 --enable-gles1 --enable-gles2
--enable-glx-tls

The environment variables when running Kodi:
export LIBGL_DRIVERS_PATH=lib
export LD_LIBRARY_PATH=lib
export VDPAU_DRIVER_PATH=lib
(lib being in the mesa git project dir)

So Kodi works, VLC already worked, but mpv is still broken. The movie starts
playing (cause I can hear the audio), which is an improvement, but the player
window is entirely blue + a lot of opengl errors in stdout. Maybe because old
mesa + new mpv is a bad idea, or maybe I did something wrong building mesa.

I'll continue to search for the specific commit that broke VDPAU in Kodi.

OK, that's me out of ideas. I can't reproduce this on my R9 285 card.

FWIW with current ffmpeg, vaapi is not a good workaround as it will eventually
use all memory. Older ffmpeg won't.

Same problem with latest mpv from git. Video never starts.

mpv 0.14.0 (C) 2000-2015

Does it work with current mpv?

Wasn't aware that Mesa offered both a VDPAU and a VAAPI driver.
mpv + VAAPI works fine, mpv + VDPAU is broken.

Mesa or the kernel is more likely.
