I use line per line CopyMemory from kernel32.dll because I don't understand how copy data from IntPtr to IntPtr by Marshal.Copy. It seems to me, It works a little bit faster then primary unsafe code.

Also YUV->RGB conversion was discussed. Can you help me in this? Can I get frames from my video files in YUV format or I must do any convertions between getting frame and copying steps?

My problem is in copying a lot of memory in textures. I need execute operation of updating for 36 images with rate 25 times per second. If I have images 300x200 size I takes about 60 ms for copying and display. But if my pictures reach 700x500 size it takes just 150 ms (I tested with 16bpp format). I think to resize my images before copying, but I don't know how to do it. can ipp libs do it? Is it realy?
