• Can't link libfdk-aac for ffmpeg on Android

  19 novembre 2015, par Steve M

  I’m trying a custom build of ffmpeg with libfdk-aac for Android. I can get ffmpeg to build without libfdk-aac and it runs, and I can build libfdk-aac.so, but when I build ffmpeg with libfdk-aac I am getting CANNOT LINK EXECUTABLE DEPENDENCIES: library "libfdk-aac.so" not found when I try to run ffmpeg. libfdk-aac.so is in the same directory as the ffmpeg executable on the Android device, and I have tried the -rpath-link linker option. Here is my complete configure for ffmpeg :
