• Mix 2 audio files with android ffmpeg android

  10 novembre 2014, par user3673182

  I am developing an android application for mixing 2 audio files.And i use android ffmpeg for that.I use following lib. from GitHub
  https://github.com/guardianproject/android-ffmpeg-java

  I use following code to mix 2 audio files from activity .

  try {
  
               File fileAppRoot = new File(getApplicationInfo().dataDir);
  
               SoxController sxCon = new SoxController(fileAppRoot, new ShellUtils.ShellCallback() {
  
                      @Override
  
                      public void shellOut(String shellLine) {
  
  
  
                          System.out.println(shellLine);
  
                      }
  
  
  
                      @Override
  
                      public void processComplete(int exitValue) {
  
  
  
                      System.out.println("hello");
  
                      }
  
                  });
  
               List<string> files=new ArrayList<string>();
  
               files.add(Environment.getExternalStorageDirectory().getAbsolutePath()+"/Testing/me.mp3");
  
               files.add(Environment.getExternalStorageDirectory().getAbsolutePath()+"/Testing/il.mp3");
  
               sxCon.combineMix(files,Environment.getExternalStorageDirectory().getAbsolutePath()+"/Testing/ial.mp3");
  
  </string></string>

  but this return exit value 2 on processComplete and no new file generated for mix audio.
  This will return following problem in logs no handler for file extension `mp3’

  Thanks for any help on this..

• How to use FFMPEG Binaries within an Android App built with Android Studio for Windows

  17 février 2016, par Valtinho

  I’ve read hundreds of pages on how to use ffmpeg in Android Studio all over the internet and none of them managed to give actual working solutions. I need to be able to trim a video selected from the gallery down to only the first 5 seconds. Ffmpeg is extremely user-unfriendly and I can’t even get it to compile successfully.

  The closest I got to compiling ffmpeg was running the app from uday-rayala called video-trimmer on github : https://github.com/uday-rayala/video-trimmer

  I downloaded the code, imported it into Eclipse and it runs and cuts videos once (it always crashes if you try a second time...). Anyway, I tried to replicate uday’s video-trimmer setup in my Android Studio app by moving the ffmpeg source files into a jni folder, and the armeabi folder inside a jniLibs folder, but the entire thing falls apart and doesn’t compile.

  Has anyone implemented ffmpeg source code within their apps ??? If so, could you please provide some working examples ? The internet is in desperate need of complete working examples for the extremely common task of video editing.
