Frank Barchard f310cb6ce1 [libyuv] Pilot OpenMP support for row processing ... Add SetMaxThreads() and GetMaxThreads() APIs (with LIBYUV_NUM_THREADS environment variable override, defaulting to half of logical cores capped at 8 when built with -fopenmp). Enable OpenMP parallel row processing for large frames (>= 1280x720) in I420ToARGBMatrix and CopyPlane (including reshaping coalesced contiguous planes across threads), and configure thread counts for ComputeHammingDistance, ComputeSumSquareError, and CalcFrameSsim. 1280x720 Benchmarks (ms): Benchmark Reps 1T 2T 4T 8T Speedup -------------------------------------------------------- I420ToARGB_Opt 1000 272 162 88 60 4.53x CopyPlane_Opt 1000 57 42 19 14 4.07x BenchmarkPsnr_Opt 1000 92 76 56 34 2.71x BenchmarkSsim_Opt 100 518 241 147 89 5.82x R=rrwinterton@gmail.com Bug: none Test: libyuv_unittest --gtest_filter=*TestSetMaxThreads*:*I420ToARGB_Opt*:*CopyPlane_Opt*:*Ssim* Change-Id: I5ca9a2b8c68eaac870da6353c51306930d015c3a CONV=a7f09b98-93ab-4652-a8eb-8d9551361f61 TAG=agy		2026-10-19 15:17:30 -07:00
