[Libva] va_getDriverName() returns -1

Wed Oct 12 08:18:17 UTC 2016

Hi Anteja,

I’m not sure which platform that you using for emgd driver? EMGD driver only support on certains platform.
First, did you manage to emgd.ko loaded and get display up?

I think you can find the user guide for setup inside in the link below just now provided by Haihao.
http://edc.intel.com/Software/Downloads/EMGD/

To get libva to work, first you need get graphics driver loaded.
I’m not sure which emgd driver release support the libva through drm but only on certain platform only but it also require the emgd.ko to be loaded first as well.

Else you can go try on using install i915 graphics driver + Iibva + libva-intel-driver. Here is the build guide setup: https://01.org/linuxgraphics/documentation/build-guide-0 and installer package https://01.org/linuxgraphics/downloads

Thanks.

Hi Anteja,

The i965_drv_video.so may needs to be linked as emgd_drv_video.so  by the following step:
Step 1: cd /usr/lib/dri
Step 2: ln –sfv i965_drv_video.so emgd_drv_video.so

You can give a try on the step above.

Thank you.

I don't think libva-intel-driver can work with emgd. You should install
emgd backend vaapi driver:

I never tried emgd before, I'm sorry that I cannot provide more help
to you on this.

Thanks
