RGB -> YCbCr

Support

Conversions Methods

• Scalar: #define RGBtoYCbCr_SIMD 0 in RGBtoYCbCr.c:10
• SSE3: #define RGBtoYCbCr_SIMD 1 in RGBtoYCbCr.c:10

Formats

• I444 (three-plane, 24bpp)
• I420 and YV12 (three-plane, 12bpp)
• I422 (three-plane, 16bpp)
• NV12 and NV21 (two-plane, 12bpp)
• NV16 and NV61 (two-plane, 16bpp)
• NV24 and NV42 (two-plane, 24bpp)
• UYVY = Y422 = UYNV (packed, 16bpp)
• YUYV = V422 = YUNV = YUY2 (packed, 16bpp)
• YVYU (packed, 16bpp)

Color Encodings

• BT.601
• BT.709
• BT.2020

Build

Windows

git clone https://github.com/MulattoKid/RGBtoYCbCr.git
cd RGBtoYCbCr/build
cmake -G "<Visual Studio Version>" ..
cmake --build . --target RGBtoYCbCr --config <DEBUG/RELWITHDEBINFO/RELEASE>

Linux

git clone https://github.com/MulattoKid/RGBtoYCbCr.git
cd RGBtoYCbCr/build
cmake -DCMAKE_BUILD_TYPE=<Debug/Release> ..
make RGBtoYCbCr -jN

Run

./RGBtoYCbCr -i <input file> -f <YCbCr format> -e <color encoding> -o <output file>

## Incorporate Into Your Own Project
1) Add the respective header and source file to your build system.
2) Note that the files in ```src/external``` directory are also needed.
3) Finally, the <RGBtoYCbCr/YCbCrtoRGB>.c contains to defines that need to be changed from 1 to 0. They are located at the top of the respective file: ```#define <RGBtoYCbCr_EXECUTABLE/YCbCrtoRGB_EXECUTABLE>```.
