I don't believe Chrome uses OpenGL directly- any OpenGL usage it does have (e.g. for WebGL) is actually going through ANGLE which translates it all to D3D on Windows.

  How to use WGL_NV_DX_interop2 to use OpenGL in a DXGI window

On Windows, another approach is to use OpenGL with DXGI. There is a barely documented extension called WGL_NV_DX_interop / WGL_NV_DX_interop2 to allow direct Direct3D and OpenGL integration. It says 'NV', but it's supported on multiple graphics vendors. Someone online has put up a GitHub repo OpenGL-on-DXGI that shows the basics. It's hell to use - you literally use two graphics APIs at once and sign every shared object in triplicate - but there is a happy path where it works. You could then render your output in OpenGL to a texture and display that texture in D3D, using the DXGI control to min frame latency.
