Fast format conversion open source library

Question

Can someone advise me open source format conversion library? Optimized for SSE, SSE2.

Formats for conversion: I420, YUY2, RGB(16-bit, 32-bit).

I found only VirtualDub Kasumi library.

Have a look at FFmpeg's libswscale library, which is licensed under the terms of the LGPL.

I'm not sure if libswscale will compile with MSVC (it probably won't), but you can always use MSYS/MingW to compile libswscale to a shared library and use that in your MSVC project.
