It looks like WMF does support 3D.

There are some other MF_MT_VIDEO_3D_* attributes defined too.

Are these Windows 8 only, or am I reading it wrong?

You're reading it right, these APIs are Windows 8 only. Additionally I think we must be using DXVA2 via D3D11 to use these APIs, but we're using DXVA2 with D3D9, so we'd need to rework some of the video/gfx internals to use DXVA2 via D3D11 if we were to use these APIs, which isn't trivial. And then we'd still not support 3D in Win7 and Vista.

So I think the only way we could support 3D stereoscopic video is by parsing the MP4 container to determine whether a video is stereo. Hopefully that data is in the MF_MT_MPEG4_SAMPLE_DESCRIPTION blob, so we don't need to parse the entire file...

Mass closing do to inactivity.
Feel free to re-open if still needed.
