Thanks for taking time to help me.
I can't find the meaning of the VC1_D. Wikipedia talks only about simple, main and advanced:L0-4 profiles. But I reckon that VC1_D doesn't include 1080i then.
Is that DirectX-thing something about Windows. My system is Ubuntu 14.04 and I tried 2014Q1 Intel Graphics Stack Release (actually Installer 1.0.5; I think it installed 2014Q1). Does that make any difference?
And the natural follow up question is: What is needed to get interlaced VC-1 working? Is it possible with intel graphics (newer processor) and Linux combination?
I received information from the engineering team and they are saying that it is possible to interlaced VC-1 1080i with Intel Graphics using newer products. We haven't heard of any issues regarding interlaced media materials on newer products in Windows, but when it comes to Ubuntu and other Linux flavors, there’s really no way to know for sure as those drivers are done as open source.
I hope this information helps.
