**libyuv** is an open source project that includes YUV scaling and conversion functionality.
* Scale YUV to prepare content for compression, with point, bilinear or box filter.
* Convert to YUV from webcam formats for compression.
* Convert to RGB formats for rendering/effects.
* Rotate by 90/180/270 degrees to adjust for mobile devices in portrait mode.
* Optimized for SSSE3/AVX2 on x86/x64.
* Optimized for Neon on Arm.
* Optimized for MSA on Mips.
### Development
See [Getting started][1] for instructions on how to get started developing.
