Intel vaapi error: can't connect to X server

mfoglio · ‎10-28-2021

I am using an EC2 with Ubuntu 18.04, CPU Intel(R) Xeon(R) Platinum 8259CL CPU @ 2.50GHz, and a Nvidia Tesla T4. It seems `vainfo` reports a problematic setup:

error: can't connect to X server!
libva info: VA-API version 1.1.0
libva info: va_getDriverName() returns -1
libva error: va_getDriverName() failed with unknown libva error,driver_name=(null)
vaInitialize failed with error code -1 (unknown libva error),exit

My goal is to use vaapi accelerated HW decoding with gstreamer in Python.

`lspci | grep VGA` returns:

error: can't connect to X server!
libva info: VA-API version 1.1.0
libva info: va_getDriverName() returns -1
libva error: va_getDriverName() failed with unknown libva error,driver_name=(null)
vaInitialize failed with error code -1 (unknown libva error),exit

Note:
- I installed on the EC2 the Nvidia drivers (not sure if they could interfere with Intel's graphic card)
- I also installed OpenVINO
- I was following this guide http://lifestyletransfer.com/how-to-install-gstreamer-vaapi-plugins-on-ubuntu/ for the setup and I got stuck at the point when I run `vaapi`

How can I fix this?

Hi,

Sorry for delay, “vainfo” normally reports the availability of the libVA on Linux platform which is the layer that connect media SDK library and kernel driver, if it is not available, Media SDK cannot use hardware acceleration in Linux.

Xeon Processors:

For Media SDK, we must make sure “Quick Sync” is included in the integrated GPU. So Xeon(R) Platinum 8259CL will not work. We only include GPU in Xeon E3.

If Nvidia's GPU takes the primary position, the integrated GPU might not be accessible. Please go through below links:
