James Zern 0200037a5a row_any,ANYDETILE: fix -Wmemset-elt-size warning 
under gcc 12.2.0 using -Wall:

source/row_any.cc: In function ‘void libyuv::DetileRow_16_Any_SSE2(const
                       uint16_t*, ptrdiff_t, uint16_t*, int)’:
source/row_any.cc:2287:11: warning: ‘memset’ used with length equal to
number of elements without multiplication by element size
[-Wmemset-elt-size]
 2287 |     memset(temp, 0, 16 * BPP); /* for msan */
      |     ~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~
source/row_any.cc:2308:1: note: in expansion of macro ‘ANYDETILE’
 2308 | ANYDETILE(DetileRow_16_Any_SSE2, DetileRow_16_SSE2, uint16_t, 2, 15)

This increases the memset to the full buffer size, which may not be
strictly necessary.

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.
  • Optimized for RVV on RISC-V.
