Ignore my changes to vainfo. This change was not necessary. I have now successfully used avcenc as well.
I still need to run with sudo or root permission? Thanks, Bob L. -----Original Message----- From: Robert J. Landle Sent: Tuesday, August 14, 2012 10:45 AM To: libva@lists.freedesktop.org Subject: RE: [Libva] using libva video compression on system with no monitor The staging branch of intel-driver compiled successfully against the staging branch of libva. I can now run: >>sudo vainfo --display drm with the correct results. But I need to run as sudo, or with root privileges? I suppose that is because we are opening the /dev/dri/card0 and /dev/dri is in the root group. Do you have any suggestions on how use this without running as sudo or root?

If I copy this function call into vainfo.c, recompile, and run >> vainfo --display drm I see va_open_display_drm gets called. I still cannot compile the intel-driver-1.0.15 with this version of libva.

But am I supposed to configure libva with --enable-x11 off, so that this function is the only option? The va_open_display_x11 function still gets called when I configure with the defaults (x11 on). This gives me an error and va_open_display_drm() never gets called. Also if I configure libva with --enable-x11 off I have problems building the intel-driver-1.0.15. Do I need a newer intel driver library to support the raw-DRM capabilities of the libva?
