  but noting work for me

  



  as you can i have no knowledge about FFMPEG so if you give answere please write in brief.

  



  thank you.

  


• Android Studio with javaCv and FFMPEG

  19 janvier 2016, par Calvin Moss

  So I am using the new Android Studio and I am trying to get JavaCV installed in the most basic setup. I made a brand new project with nothing in it, imported (I think unsuccessfully) the JavaCV library and then I am running one of the samples given in the JavaCV repo and I am getting the following error.

  I have read several of the other top posts on the issue but I cannot figure out what is wrong. I downloaded the JavaCV through gradle, then I added the lib and lib/areabi folders. I imported ffmpeg.jar, javacpp.jar, javacv.jar and opencv.jar all to the lib folder. and I extracted all the .SO files from opencv-android-arm.jar and ffmpeg-android-arm.jar and put them in the lib/armeabi just like the instructions on the git repo. I cannot figure out what is going on. Anyone have any ideas ? Also my current setup is. Project->AppModule and then inside of that is where I have my lib and inside of lib i have the armeabi. Does anyone have any info on whats going on ?

• java.lang.NoClassDefFoundError Android Studio Unity

  28 avril 2016, par Nestoraj

  I’m having some troubles when I try to generate a library that contains another one in Android Studio. First of all I am using Android Studio 2.0 and Unity 5.3.4f1. What I want to do is integrate FFMpeg in Unity so I decided to create my own library that use FFMpeg library as an intermediary. The FFMpeg library is here.

  To start I created a new empty project in Android Studio and inside of it, created a new module, which will be my library, using New->Module->Android Library and named it "ffmpegcodec". After that I opened build.gradle file inside the new module folder and paste :

  compile 'com.writingminds:FFmpegAndroid:0.3.2'

  inside dependencies brackets, and click Sync (It did not show any error).

  After that create a new Java Class inside src/main/java/package-name/ and named it FFMpegCodec. Inside this paste this code :

  public class FFMpegCodec {
  
  private static FFmpeg ffmpeg;
  
  private static Context context;
  
  private static FFMpegCodec INSTANCE = null;
  
  
  
  public FFMpegCodec(){
  
      INSTANCE = this;
  
  }
  
  
  
  public static FFMpegCodec instance(){
  
      if(INSTANCE == null){
  
          INSTANCE = new FFMpegCodec();
  
      }
  
      return INSTANCE;
  
  }
  
  
  
  public void setContext(Context ctx){
  
      this.context = ctx;
  
  }
  
  
  
  public void loadFFMpegBinary() {
  
      try {
  
          if (ffmpeg == null) {
  
  
  
              ffmpeg = FFmpeg.getInstance(context);
  
          }
  
          ffmpeg.loadBinary(new LoadBinaryResponseHandler() {
  
              @Override
  
              public void onFailure() {
  
                  Log.e("FFMPEG", "ffmpeg : NOT correct Loaded");
  
              }
  
  
  
              @Override
  
              public void onSuccess() {
  
                  Log.e("FFMPEG", "ffmpeg : correct Loaded");
  
              }
  
          });
  
      } catch (FFmpegNotSupportedException e) {
  
  
  
      } catch (Exception e) {
  
  
  
      }
  
  }
  
  
  
  public void execFFmpegCommand(final String[] command) {
  
      try {
  
          ffmpeg.execute(command, new ExecuteBinaryResponseHandler() {
  
              @Override
  
              public void onFailure(String s) {
  
                  Log.e("FFMPEG", "FAILED with output : " + s);
  
              }
  
  
  
              @Override
  
              public void onSuccess(String s) {
  
                  Log.e("FFMPEG", "SUCCESS with output : " + s);
  
              }
  
  
  
              @Override
  
              public void onProgress(String s) {
  
                  Log.e("FFMPEG", "Started command : ffmpeg " + command);
  
                  Log.e("FFMPEG", "progress : " + s);
  
              }
  
  
  
              @Override
  
              public void onStart() {
  
                  Log.e("FFMPEG", "Started command : ffmpeg " + command);
  
  
  
              }
  
  
  
              @Override
  
              public void onFinish() {
  
                  Log.e("FFMPEG", "Finished command : ffmpeg " + command);
  
  
  
              }
  
          });
  
      } catch (FFmpegCommandAlreadyRunningException e) {
  
          // do nothing for now
  
      }
  
  }

  It basically generates an instance of FFmpeg and makes calls of ffmpeg commands.

  Once I have my lib done I decided to test it in my project so I include my lib in my app graddle using :

  compile project(':ffmpegcodec')

  After that I just paste this code to my MainActivity :

  public class MainActivity extends AppCompatActivity {
  
  
  
  FFMpegCodec ffmpeg;
  
  
  
  @Override
  
  protected void onCreate(Bundle savedInstanceState) {
  
      super.onCreate(savedInstanceState);
  
      setContentView(R.layout.activity_main);
  
  
  
      Button execCommandButton = (Button) findViewById(R.id.execCommandButton);
  
  
  
      ffmpeg = FFMpegCodec.instance();
  
  
  
  
  
      execCommandButton.setOnClickListener(new View.OnClickListener() {
  
          @Override
  
          public void onClick(View v) {
  
              Toast.makeText(getApplicationContext(), "This is a Toast!!", Toast.LENGTH_SHORT).show();
  
              ffmpeg.setContext(MainActivity.this);
  
              ffmpeg.loadFFMpegBinary();
  
              String []cmd = new String[1];
  
              cmd[0] = "-version";
  
              ffmpeg.execFFmpegCommand(cmd);
  
          }
  
      });
  
  
  
  }

  After that, I run my project and when I press the button it returns that everythings its ok, showing ffmpeg version.
  Once I have check that my lib works I decide to move it to Unity so copy the ffmpegcodec-realese.arr file inside ffmpegcodec/build/outputs/aar folder and paste it into my Unity project. Then I wrote an C# script to use my lib that contains this :

      using System;
  
      using System.Runtime.InteropServices;
  
      using UnityEngine;
  
      using System.Collections;
  
      using System.Diagnostics;
  
  
  
      public class ScreenRecorder {
  
  
  
      private AndroidJavaObject unityActivity = null;
  
      private AndroidJavaObject captureObject = null;
  
  
  
          // Use this for initialization
  
          public ScreenRecorder () {
  
              try{
  
  
  
                  using (AndroidJavaClass unityPlayerActivityClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer")) {
  
                      unityActivity = unityPlayerActivityClass.GetStatic<androidjavaobject>("currentActivity");
  
                  }
  
  
  
                  AndroidJavaClass captureClass = new AndroidJavaClass ("com.promineostudios.ffmpegcodec.FFMpegCodec");
  
                  if (captureClass != null) {
  
                      captureObject = captureClass.CallStatic<androidjavaobject>("instance");
  
                      captureObject.Call("setContext", unityActivity);
  
                      captureObject.Call("loadFFMpegBinary");
  
                  }
  
              }catch(Exception ex){
  
                  UnityEngine.Debug.Log(ex);
  
              }
  
          }
  
  
  
      }
  
  </androidjavaobject></androidjavaobject>

  The problems comes here. When I create a class instance using :

  AndroidJavaClass captureClass = new AndroidJavaClass ("com.promineostudios.ffmpegcodec.FFMpegCodec");

  It creates an instance correctly, and also when I create an object using :

  captureObject = captureClass.CallStatic<androidjavaobject>("instance");
  
  </androidjavaobject>

  But when I try to get access to FFMpeg library methods like in "setContext" it fails and returns this :

  UnityEngine.AndroidJavaException: java.lang.NoClassDefFoundError: Failed resolution of: Lcom/github/hiteshsondhi88/libffmpeg/FFmpeg;

    at com.unity3d.player.UnityPlayer$b.run(Unknown Source)

  I think that the problem is in when I export my lib into Unity but I do not know what is going wrong. If anybody could help me I will be really appreciated.

  Thanks and excuse me for my English.
