Frank Barchard 2ed2402fa0 I420ToI010 for 8 to 10 bit YUV conversion. 
Convert planar 8 bit formats to planar 16 bit formats.

Includes msan fix for Convert8To16Row_Opt unittest.

I420 is YUV bt.601 8 bits per channel with 420 subsampling.
I010 is YUV bt.601 10 bits per channel with 420 subsampling.
I is color space - bt.601.  The function does no color space
 conversion so H420ToI010 is aliased to this function as well.
0 = 420 subsampling.  The chroma channels are half width / height.
10 = 10 bits per channel, stored in low 10 bits of 16 bit samples.

For SSSE3 version:
out/Release/libyuv_unittest --gtest_filter=*LibYUVConvertTest.I420ToI010_Opt --libyuv_width=1280 --libyuv_height=720 --libyuv_repeat=999 --libyuv_flags=-1 --libyuv_cpu_info=-1
[ RUN      ] LibYUVConvertTest.I420ToI010_Opt
[       OK ] LibYUVConvertTest.I420ToI010_Opt (276 ms)

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.
