vaInitialize failed with error code -1 (unknown libva error)

[Alon__Alon]

Dear Shubha,

When I run vainfo I get this error:

libva info: VA-API version 1.4.1
libva info: va_getDriverName() returns -1
libva info: User requested driver 'iHD'
libva info: Trying to open /opt/intel/mediasdk/lib64/iHD_drv_video.so
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit

I use 19.04 linux version, How can I resolve this?

Does file /opt/intel/mediasdk/lib64/iHD_drv_video.so exists? Does command "ldd /opt/intel/mediasdk/lib64/iHD_drv_video.so" works? Does your user have access to devices in "/dev/dri/" directory?

Thanks Maksim!

I did some changes and now when I run vainfo I get this error:

libva info: VA-API version 1.4.1

The command "ldd /opt/intel/mediasdk/lib64/iHD_drv_video.so" works and the output is:

I don't find the /dev/dri/ directory.

Looks like you don't have a driver for your iGPU or it is broken. What does "lscpu" command prints? Try to ask in specialized forum: https://software.intel.com/en-us/forums/intel-media-sdk
