• Importing sub module of FFmpeg in Android

  3 mars 2024, par M. Usman Khan

  I was able to import the "full" module of FFmpeg library in Android like this :

  


  api 'com.arthenica:ffmpeg-kit-full:6.0-2'


  


  But this was adding about 90mb to my app. So I tried to import only "min-gpl" like

  


  api 'com.arthenica:ffmpeg-kit-min-gpl:6.0-2'


  


  But instead of decreasing, this actually increased my app size further (about 100mb).

  


  Am I not doing it right ?
