  • arm-linux-androideabi/bin/ld : error : cannot find -lpolarssl while compiling rtmp library for Android (host os -Debian)

    24 octobre 2014, par trololo

    I’m trying to build rtmp library for ffmpeg for my Android app.
    In order to compile ffmpeg I have to compile rtmp-library.
    For librtmp.a I need to compile polarssl. I got polarssl library (libpolarssl, -lpolarssl)
    script for polarssl :

  • Revision 7045aec00a : SAD32xh and SAD64xh for AVX2 All sad function that process above 32 consecutive

    2 octobre 2014, par levytamar82

    Changed Paths :
     Modify /test/sad_test.cc


     Modify /vp9/common/vp9_rtcd_defs.pl

    SAD32xh and SAD64xh for AVX2

    All sad function that process above 32 consecutive elements are optimized
    for AVX2 :
    vp9_sad64x64
    vp9_sad64x32
    vp9_sad32x64
    vp9_sad32x32
    vp9_sad32x16

    vp9_sad32x64_avg
    vp9_sad32x32_avg
    vp9_sad32x16_avg
    The functions that appeared as a hotspot is vp9_sad32x32 and vp9_sad64x64
    vp9_sad32x32 was optimized by 68% and vp9_sad64x64 was optimized by 90%
    both of them gave and overall 2.3% user level gain
