We come across an issue and finally we find the root cause. We have a server application which using Intel Sdk Linux version. During the running, if no one logins to that Linux host machine from Gui side, the initialization function vaInitialize will fail and we fail to create decode/encode feature. so we need manually login to that machine then rerun the application. Does Intel SDK need x-server runing to offer the full feature?
Media SDK for Linux Servers is designed to support headless operation.
Which release are you using? Earlier releases had a DRM and X11 mode. DRM mode would work in an X11 environment or remotely. If you installed with X11 mode then an active X session would be required. Newer releases don't require you to make this choice at install.
Please install the latest release. Don't forget to remove all libdrm* files from /usr before installing, since Media SDK now includes its own version and multiple versions of libdrm on the system can cause strange behavior.
