  30 mars 2016, par tqn

  i’m working in a video processing project and now i’m using ffmpeg library in Android. I’m facing with a strange problem with asus zenphone 4 t00l (or all x86 device, I’ve just test in this x86 phone). When start command in project, app always crash :

  First, I think the problem is ffmpeg library. So I created a test module with simple activity just load and run command and there’re no problem.

  Second, I’m afraid that app cannot load version ffmpeg, because in my log, it’s armv7-neon althought it’s x86 (In my test module, it display x86). And according my search result, may be a external library make app to use abi arm (Build.CPU_API="armv7"). So I try remove all library in gradle in module Test and detected a library. But check in aar file of library, it support all x86 and arm. But after remove it, app still crash with same log. And strangely, althogh Test module register as arm but it’still run success (External question : Why add library jp.wasabeef:picasso-transformations make system register as armv7 although it’s x86)

  Finally, i think problem is command. But after debug, I use same command for Test module but it still success. Now i’m still stuck with it. Could anyone help me to solve it. Thanks. Here my demo code :

      String input = "/storage/emulated/0/Videa/Video/VIDEO_20160122_160020.mp4";
  
      String output = "/storage/emulated/0/Videa/Audio/AUDIO_20160330_142501.wav";
  
      String[] command = {
  
              "-y",
  
              "-i",
  
              input,
  
              "-vn",
  
              "-f",
  
              "wav",
  
              output
  
      };
  
      FFmpeg ffmpeg = FFmpeg.getInstance(getApplicationContext());
  
      try {
  
          ffmpeg.execute(command, new ExecuteBinaryResponseHandler() {
  
  
  
              @Override
  
              public void onSuccess(String message) {
  
                  super.onSuccess(message);
  
                  System.out.println("Success " + message);
  
              }
  
  
  
              @Override
  
              public void onFailure(String message) {
  
                  super.onFailure(message);
  
                  System.out.println("Failure " + message);
  
              }
  
          });
  
      } catch (Exception e) {
  
          e.printStackTrace();
  
      }

  And here is Failed command :

      ArrayList<string> cmd = new ArrayList<string>();
  
      cmd.add("-y");
  
      cmd.add("-i");
  
      cmd.add(input);
  
      cmd.add("-vn");
  
      cmd.add("-f");
  
      cmd.add("wav");
  
      cmd.add(output);
  
      String[] result = new String[cmd.size()];
  
      return cmd.toArray(result);
  
  </string></string>

• Embedding pure python(Cpython) on android

  13 août 2020, par KiYugadgeter

  I want to create movie download app for android for learn.
To make develop easily, I would like to use youtube-dl for downloader backend.

  


  So I want to embed Cpython runtime and ffmpeg (for convert movie format) to Android app.
Is it able to do with android NDK ?

  


  Note that I know more better ways are exist.(like use java-friend python runtime or downloader implement as online server)

  


  But I want to try to embed python and ffmpeg in app for learn.

  


  Can it with Android NDK ?

  


• How to add dagger in my android studio project

  14 janvier 2016, par Vijay

  I am trying to compress the video using ffmpeg in android. I found one good example and I downloaded the project from https://github.com/WritingMinds/ffmpeg-android-java. It’s working fine. When I try to add that ffmpeg library in my project I am facing error. After make many changes I resolved many issues. But I can not clear the following issue :

  Error:(34, 13) Failed to resolve: com.squareup.dagger:dagger-compiler:1.2.2
  
  
  
  Error:(35, 13) Failed to resolve: com.squareup.dagger:dagger:1.2.2

  I decided to download the dagger.jar and dagger-compiler.jar. I download the jar and I added into my project. But I am facing another error.

  Error:Execution failed for task ':ContainerCentralen:compileDebugJava'.
  
  > java.lang.NoClassDefFoundError: javax/inject/Scope

  I can not solve this two issues. Please let me any idea to resolve this issue.
