now want add in chroma-key effect, described in below like:

so how id2d1devicecontext idirect3ddevice9 , add chorma-key effect , render video frame?

id2d1devicecontext requires directx11 device , can not used obsolete idirect3ddevice9. typically create objects in following order: dxgi factory, d2d1 factory, d3d11 device, dxgi device, d2d1 device , d2d1 device context. may want check d2d getting starting guide , samples.

there no real point in dealing directx9 anymore, unless forced provide backward compatibility windows xp. chroma-key sample posted requires windows 10.
