MultiplyRow_16_AVX2 for converting 10 bit YUV

When converting from lsb 10 bit formats to msb, the values
need to be shifted to the top 10 bits.  Using a multiply
allows the different numbers of bits to be copied:
// 128 = 9 bits
// 64 = 10 bits
// 16 = 12 bits
// 1 = 16 bits

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.
