Virtualbox and VA-API

[simonprewo]

Hello together,

I am trying to get VA-API to run in a virtual box... I do not need the perfomance - the libarary is just needed by some of my tools.

Output of vainfo

Code: Select all

app@app-VirtualBox:~$ vainfo
libva info: VA-API version 0.35.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/vboxvideo_drv_video.so
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit

I have the following configuration:
Host: Windows 9 (64 Bit), Graphic Card NVIDIA Quadrio K2100M
Guest: Ubuntu 16.4 (64 Bit), 3D-Acceleration enabled (in preferences)

My question are:

• Do I need to install any graphic driver on the VM?
• Does the VM uses the graphic card or emulates it on the CPU?
• How do I get this to work?

Thanks a lot for any help
Simon

I really hope that VA-API stands for "Video Acceleration API", otherwise I'm in the wrong...

Do I need to install any graphic driver on the VM?

You can't. I believe that the newest drivers are the ones that come with a newer VirtualBox version.

Does the VM uses the graphic card or emulates it on the CPU?

It emulates it on the CPU.

How do I get this to work?

No clue. Is there maybe a VB-API stub library?

Is there any update? Like can we use VA-API in virtualbox with any special drivers or setup?
