Bug#956281: Tries to load `iris_drv_video.so` but `iHD_drv_video.so` is installed
Package: vainfo
Version: 2.6.0+ds1-1
Severity: normal
Dear Debian folks,
With an Intel Broadwell laptop
$ lspci -nn -s 0:2
00:02.0 VGA compatible controller [0300]: Intel Corporation HD
Graphics 5500 [8086:1616] (rev 09)
I am trying to get H264 decoded on the GPU. Therefore, I installed
*intel-media-va-driver-non-free* [1], which uninstalled
*intel-media-va-driver*. Now, `va_openDriver()` fails to load the
appropriate library.
```
$ vainfo
libva info: VA-API version 1.7.0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/iris_drv_video.so
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit
$ sudo ln -s /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so
/usr/lib/x86_64-linux-gnu/dri/iris_drv_video.so
$ vainfo
libva info: VA-API version 1.7.0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/iris_drv_video.so

vainfo: VA-API version: 1.7 (libva 2.6.0)

```
How should the non-free library be included appropriately? It really
makes a difference as mpv usages drops from around 40 % to 12 %.
Kind regards,
Paul
