C library for fast image conversion between yuv420p and rgb24.
This is a simple library for optimized image conversion between YUV420p and rgb24.
It was done mainly as an exercise to learn to use sse instrinsics, so there may still be room for optimization.
It was done mainly as an exercise to learn to use sse intrinsics, so there may still be room for optimization.
For each conversion, a standard c optimized function and two sse function (with aligned and unaligned memory) are implemented.
The sse version requires only SSE2, which is available on any reasonnably recent CPU.

The library also supports the three different YUV (YCrCb to be correct) color spaces that exist (see comments in code), and others can be added simply.
There is a simple test program, that convert a raw YUV file to rgb ppm format, and measure computation time.
Optionnaly, it also compares the result and computation time with the ffmpeg implementation (that uses MMX), and with the IPP functions.
