Hi.
I'm trying to programmatically capture stereoscopic video of older DirectX games. None of the known capture programs can do this: Fraps can capture DirectX 9+ S3D but the others (Bandicam, Taksi, PlayClaw) can't record any S3D. This game is DirectX 8 and it displays wonderfully in stereo 3D, but I haven't been able to record it.

I've experimented with the standard Windows BitBlt function but that only captures one side of the stereo.

What nVidia library calls exist which let me access both sides of the stereo buffer?

Is there any documentation, or even just a full list of nVidia DLL calls which I can browse and experiment with? Are there examples I could use as starting point?

I think there should be a solution since the nV stereo screen capture hotkey (Alt+F1) can save nice side-by-side images in DirectX 8 games. If that hotkey can read the full stereo buffer, there should be a way for external programs to do the same!


Any sort of help is much appreciated. If no such standard calls exist for pre-DirectX9, I could still use a DirectX9 example, or the names of the relevant DirectX9 calls; maybe I find something suitable based on those.

Thanks!
