Fast format conversion open source library [closed]

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

I found only VirtualDub Kasumi library.

Answer 1

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.

libyuv is an open source project that includes YUV scaling and conversion functionality.
