George Steed 45c7107f95 [AArch64] Fix compilation when SME is not supported 
The STREAMING_COMPATIBLE macro is designed to enable use of the
__arm_streaming_compatible attribute with the intent that this macro
expanded to empty if SME is not supported by the compiler or platform
being compiled for, however in reality this macro remained undefined
causing compilation to fail. Fix this by defining the macro to empty as
originally intended.

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/SVE2/SME on Arm.
  • Optimized for MSA on Mips.
  • Optimized for RVV on RISC-V.
