Frank Barchard 37f9721052 Add LibYUVConvertTest.TestH010ToAR30 unittest 
Tests accuracy of H010ToAR30 on grey scale ramp against float
and computes a histogram to detect number of unique shades for
each channel.

With 2 step intermediate using 8 bit RGB, the test shows 256
unique values.

[ RUN      ] LibYUVConvertTest.TestH420ToARGB
uniques: B 220, G, 220, R 220
[       OK ] LibYUVConvertTest.TestH420ToARGB (0 ms)
[ RUN      ] LibYUVConvertTest.TestH010ToARGB

README.md

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.
