      Add LibYUVConvertTest.TestH010ToAR30 unittest · 37f97210
      Frank Barchard authored 
      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.

      H010ToAR30 optimized to 2 step conversion · 9d2cd6a3
      Frank Barchard authored 
      Previously H010ToAR30 was done in a 3 step conversion:
H010ToH420, H420ToARGB, ARGBToAR30.
This CL merges the first 2 steps into H010ToARGB, to
improve performance.
Caveat - only 10 bit YUV is supported at this time.
Previously the low level code supported different numbers
of bits - 9, 10, 12 or 16.

Was 3 step conversion:
LibYUVConvertTest.H010ToAR30_Any (1263 ms)
LibYUVConvertTest.H010ToAR30_Unaligned (951 ms)
LibYUVConvertTest.H010ToAR30_Invert (913 ms)
LibYUVConvertTest.H010ToAR30_Opt (901 ms)

Now 2 step conversion:
LibYUVConvertTest.H010ToAR30_Any (853 ms)
LibYUVConvertTest.H010ToAR30_Unaligned (811 ms)
LibYUVConvertTest.H010ToAR30_Invert (781 ms)
LibYUVConvertTest.H010ToAR30_Opt (755 ms)

      Allow enabling libyuv symbols visibility for shared library targets · 56eb5a47
      VladimirTechMan authored 
      When developing WebRTC applications with custom video sources, libyuv's
API is often the required part of the project. For that, application
developers can link with a separate standalone instance of libyuv.
However, it is even better to avoid that binary code duplication and
link against libyuv as a part compiled into the WebRTC library.

When building WebRTC as a static library target, the symbols from libyuv
are normally accessible to the linker without any extra actions. When
building WebRTC as a shared library, that does not work as the exported
symbols are those marked as visible, while libyuv is built with the
hidden visibility setting by default.

This patch adds an extra flag to enable switching the symbol visibility
to default when building shared library targets depending on libyuv in
WebRTC and Chromium projects. By default the flag is not enabled,
preserving the prior behaviour.

Bug: NONE
