Im rendering camera stream with directx 9, but it displays stream a little bit foggy, something like a gray overlay on it. I figure out it when my result is compared to VLC.

Im getting YUV arrays via ffmpeg and using Direct3DSurface9 lock rectangle for memory copy. After copy, i get backbuffer and strech it. Finally present it.

I tried D3DMATERIAL9 but no effects for me. If im not wrong, material effects is used for vertex. Then tried SetDeviceGammaRamp didnt work again.

This is how i create my surface

d3d9Dev->CreateOffscreenPlainSurface(_srcWidth,_srcHeight,(D3DFORMAT)MAKEFOURCC('Y','V','1','2'), D3DPOLL_DEFAULT, &d3d9Surface, NULL);

---

EDIT

I get stream from camera as YUV format and I did not convert it to RGB. YUV format scales 16-235. Therefore my program shows colors foggy. I changed my format BGRA via ffmpeg. This solves my problem.
