    Convert16To8Row_SSSE3 port from AVX2 · 324fa327
    Frank Barchard authored 
    H010ToAR30 uses Convert16To8Row_SSSE3 to convert 10 bit YUV to 8 bit.
Then standard YUV conversion can be used.  This improves performance
on low end CPUs.
Future CL will by pass this conversion allowing for 10 bit YUV source,
but the function will be useful as a utility for YUV conversions.

Bug: libyuv:559, libyuv:751

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.
