• Error while linking shared library FFMpegJNI to android project

  5 mars 2024, par Dari V

  I have built an ffmpeg module for all the architectures, but when I try to build project to run it on emulator (x86 architecture) i get an error, indicating that the files for x86 architecture are incompatible with elf_i386. The same is for other architectures, i get the error that the files are incompatible. What can i do in this case ?

• Adding ffmpeg library to Python Kivy App and Buildozer for Android

  15 août 2023, par Chris-Yoon

  I am working on a Python Kivy App, in which I have to manipulate audio files such as joining audio files or converting them into aac format. In order to achieve this I use the ffmpeg library. Everything works fine on my Linux machine, however, I couldn't make it run on the Android device. I build my apk/aab file by using Buildozer. I built a variety of cross-platform apps for Windows or Linux or for the web, but I am not really an experienced Android developer.

  


  Can someone give me a high-level explanation or even a detailed description on how I can add this third party library to the apk/aab file and define it as environment variable using buildozer, so that other modules such as ffmpeg-python or pydub can find it ? I am also open to alternatives if there are any.

  


  I tried ffmpegkit, adding prebuilt libraries, defining the path to the converter in PyDub.
