Sanity check for Media Server Studio fails

I followed installation process at  your HOWTO "How to enable Intel® Media Server Studio on Ubuntu14.04 LTS" in this forum. Everything builds an installs OK, but sanity check failed: Xlib:  extension "XFree86-DRI" missing on display "localhost:10.0".

I suppose this is a problem due to ssh -X to the Ubuntu server. Do you know a workaround for checking if erverything is working as expecting?

Have you run the "export DISPLAY..." variable to set the right value for your server display? since you're using ssh.

Thanks!

Hi Chunbo,

Did another test: Started inside my ssh connection an xterm, inside that session I set environment and run "vainfo". Here's the output:

~$ vainfo 
libva info: VA-API version 0.35.0
vainfo: dri2_util.c:199: isDRI2Connected: Assertion `dri_state->base.fd >= 0' failed.
Aborted (core dumped)
~$

Whats wrong?

Could you show me the command you run for "export DISPLAY.."?

Another suggestion is that you log onto your Ubuntu server locally to run the VAINFO in X11. Let me know whether is works or not.

Hi Chunbo,

Here's what I did:
- ssh to Ubuntu Server (its a virtual machine at ESXi)
- inside that ssh started a xterm (the xterm is shown at my local machine: $ echo $DISPLAY: localhost:10.0 )
- inside that xterm I get following error message:

~$ vainfo 
libva info: VA-API version 0.35.0
vainfo: dri2_util.c:199: isDRI2Connected: Assertion `dri_state->base.fd >= 0' failed.
Aborted (core dumped)

OK. The current MSS package has not been supported on Virtual Machine...

Is there a chance for a (unsupported) workaround?

Not till now in my knowledge. The good thing is that the virtualization of MSS advantage should be probably ready and released next year.

Stay tuned!

Is there an update for supporting MSS in virtual environments.

Not for production, but for developing/testing it would be helpful. And - to my knowledge, Intel Skylake Xeons of newest generations are supporting hardware based transcoding at Vsphere/ESXi 6 too.

Thanks!
