it must root ?

There can be many causes for errors starting Media SDK.  Quite often these can be traced to installation.

Which processor are you running on, which Linux distribution, and which release of Media SDK for Linux?

Here is a quick checklist for installation:

1) Verify that the processor is supported (chipset too for Xeon).  Supported configuration requirements in the release notes are very specific.
2) Verify supported kernel level (in release notes)
3) Check that Intel integrated graphics is available with '$ lspci -nn | grep "VGA" '
4) Remove all versions of libdrm before installing 
5) after install, check that the i915 module loaded with '$ lsmod | grep i915'
6) Verify that the user running the Media SDK application is in the 'video' group

If there are problems running as a regular user, running as root may often help.  There are still some issues with running multiple sessions where running as root is a workaround.
