Yuan Tong a85cc26fde Add MergeARGBPlane and SplitARGBPlane
These functions convert between planar and interleaved ARGB,
optionally fill 255 to alpha / discard alpha.

This can help handle YUV(A) with Identity matrix, which is
basically planar ARGB.

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.
