Hi, I am trying to implement a Stereo Movieplayer using nvidia drivers(HW page flip). I downloaded the NVAPI.h and enabled the driver.(don't know if that really helped)and using directx , i created two surfaces.left and right. Stretched the video surface into the back buffer.locked em and use the stereo signature. This works for images. It's horribly slow though. However,I want to do it for 2 videos.I have the right and left ones. I need advice as to how I should load the videos on the surface(direct show? DirectDraw?) use the drivers to perform HW page flip? Any help would be greatly appreciated. Thank u! | ||

The way i do it is gImageSrc->LockRect(&lr,NULL,0); LPNVSTEREOIMAGEHEADER pSIH = (LPNVSTEREOIMAGEHEADER)(((unsigned char *) lr.pBits) + (lr.Pitch * (gImageHeight))); pSIH->dwSignature = NVSTEREO_IMAGE_SIGNATURE; pSIH->dwBPP = 32; pSIH->dwFlags = SIH_SWAP_EYES; pSIH->dwWidth = gImageWidth*2; pSIH->dwHeight = gImageHeight; gImageSrc->UnlockRect(); I need to do it for videos. Please help!! This works but it damn slow. |
