Bug#664700: libva1: please search dri module in /usr/lib/{<triplet>/, }dri

[Andreas Beckmann]

Package: libva1
Version: 1.0.15-4
Severity: normal

Hi,

please use a search path for the DRI modules that contains both
  /usr/lib/<triplet>/dri
  /usr/lib/dri
While we can (hopefully) fix the Debian packages to ship the files in
the multiarch locations, the multiarch move "breaks" any third-party
(probably proprietary) software/installer/... that is not multiarch
aware. Therefore "plugins" should be searched in both locations.

So far the following problems have been reported:

xvba-va:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=664487

fglrx + vainfo:

$ vainfo
libva: VA-API version 0.32.0
Xlib:  extension "XFree86-DRI" missing on display ":0".
libva: va_getDriverName() returns 0
libva: Trying to open /usr/lib/x86_64-linux-gnu/dri/fglrx_drv_video.so
libva: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit

I'm not sure if I can move dri/fglrx_drv_video.so around - it is loaded
from the fglrx driver (a non-free blob) using the hardcoded path
/usr/lib/dri ... (and the last time I tried to use symlinks (although in
a different context) the fglrx blob used lstat() and complained about
world writable files ...)
