Chris can you revert https://codereview.chromium.org/2696963002? Seems suspicious for video failures:

Replace IMFTransform with ID3D11VideoProcessor

As far as I can tell, ID3D11VideoProcessor is the only one that understands
how to convert HDR10 content into scRGB textures. A future change will enable
use of this in order to properly decode HDR content.

Hubbe, this bot is not run on the CQ, but is an important test because it represents most of our Windows users.

Yeah, looks like d3d11_device_context_ isn't initialized if share_nv12_textures_ is true, so that code crashes.

John, Chris doesn't seem to be available, can you handle the revert?
