  • Build latest version of FFMPEG with libx264 Android

    12 novembre 2016, par Biraj Zalavadia

    I was able to Build FFMPEG with libx264 Android successfully and was working well before 2 months.

    I uses halfninja for building.

    Today I take latest source of ffmpeg and libX264 from here.

    git clone git://git.videolan.org/x264.git
    

    
git clone git://git.videolan.org/ffmpeg.git

    And try to rebuild whole project. But now it throws following errors.
