Some checks failed
CMake / build (push) Has been cancelled
This patch includes handwritten avx2 intrinsics to optimize the libavc sw decoder by reducing CPU-cycles overhead on module : libcodec2_soft_avcdec. Playing 1024 resolution video playback on the Galley App with HW decoder disabled: cpu-cycles overhead(%) reduced by ~15%. Loading of video thumbnails on Gallery/Photos App is faster (we have pushed approx more than 30 videos as a part of the usecase): cpu-cycles overhead(%) have reduced by ~10%.This patch is related to s/w video decoding.
