I observed segfaults on both crownbay & emenlow. The video plays fine, but at the end of video play back there is a segfault.
The issue was coming from EMGD library's expectation of data value from libva library. I will check tomorrow if we can fix 
libva 1.1.0 to work with EMGD libraries properly. But at least we have one solution to the issue now, to unblock the 
release.

That is different thing. The claimed Graphics stack is for Core BSPs. EMGD based BSPs has different graphics stack.
