• How to build FFmpeg (ver 3.1.1) on Android Studio (ver 2.1.2)

  20 juillet 2016, par Jake Park

  I try to build and use FFmpeg Library on Android Studio.

  My Environments

  Windows 7 64bit, Cygwin64, Android Studtio 2.1.2, FFmpeg 3.1.1, Android NDK r12b

  Ref. Page

  http://www.roman10.net/2013/08/18/how-to-build-ffmpeg-with-ndk-r9/ I follow this page.

  I succeed FFmpeg library build using ./build_android.sh on Cygwin

  so I try to use FFmpeg Library’s on Android Studio.
