• Im failing to build .so file for android from FFMPEG

  15 juillet 2020, par yejafot

  I tried many times with different versions of ffmpeg but failed eventually. I dont know how they wrote .sh file to configure different tools. Here are some .sh files i tried and it all failed. Either it shows only android/share folder instead of

  


  


  • android/include

    


  


  • android/lib

    


  


  • android/share

    


  


  


  OR

  


  i end up in error like no file or folder exist,etc

  I'm using

  


  


  • ffmpeg-snapshot.tar.bz2

    


  


  • android-ndk-r21d-linux-x86_64

    


  


  


  the only thing i know in 'ndk 21` is we need to use default toolchain (android documentation says).

  


  How to create .sh file to build .so file to use in android ?

  


• Revision 31972 : Et maintenant on peut aussi importer les fichiers d’export. On peut aussi ...

  8 octobre 2009, par rastapopoulos@… — Log

  Et maintenant on peut aussi importer les fichiers d’export.
  On peut aussi supprimer entièrement un menu, ce qui n’était bizarement pas possible avant.
  Pour la peine, on hausse la version, parce que c’est une nouvelle fonctionnalité d’ajoutée.
