Additional IP Rights Grant (Patents)
"This implementation" means the copyrightable works distributed by
Google as part of the LibYuv code package.
Google hereby grants to you a perpetual, worldwide, non-exclusive,
no-charge, irrevocable (except as stated in this section) patent
license to make, have made, use, offer to sell, sell, import,
transfer, and otherwise run, modify and propagate the contents of this
implementation of the LibYuv code package, where such license applies
only to those patent claims, both currently owned by Google and
acquired in the future, licensable by Google that are necessarily
infringed by this implementation of the LibYuv code package. This
grant does not include claims that would be infringed only as a
consequence of further modification of this implementation. If you or
your agent or exclusive licensee institute or order or agree to the
institution of patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that this
implementation of the LibYuv code package or any code incorporated
within this implementation of the LibYuv code package constitutes
direct or contributory patent infringement, or inducement of patent
infringement, then any patent rights granted to you under this License
for this implementation of the LibYuv code package shall terminate as
of the date such litigation is filed.

**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.
* Convert from YUV to formats for rendering/effects.
* Rotate by 90/180/270 degrees to adjust for mobile devices in portrait mode.
* Optimized for SSE2/SSSE3/AVX2 on x86/x64.
* Optimized for Neon on Arm.
* Optimized for DSP R2 on Mips.
### Development
See [Getting started] [1] for instructions on how to get started developing.
You can also browse the [docs directory] [2] for more documentation.
