  im trying to combine set of images and audio into one video file
  but whenever I try to record a frame of audio on to the ffmpegframerecorder,it gives the error ffmpegframerecorderexception no audio output stream.can anyone please help me with this problem ?

  public void newrecording() 
  
  {
  
      try {
  
  
  
          Log.d("Record",
  
                  "Environment.getExternalStorageDirectory().getPath()  : "
  
                          + path);

          FFmpegFrameRecorder recorder = new FFmpegFrameRecorder(path1
  
                  + "/"+System.currentTimeMillis()+".mp4",200,150);

          recorder.setFrameRate(100); // This is the frame rate for video. If
  
          // you really want to have good video
  
          // quality you need to provide large set
  
          // of images.
  
          recorder.setPixelFormat(0); // PIX_FMT_YUV420P

• Importing a part of a project in Eclipse

  10 mars 2015, par Arif Gencosmanoglu

  On Eclipse, I imported FFmpeg as a project to reduce a selected video sizes for my android application. But my .apk size went up from 2MB to 24MB.

  This project includes a lot of extra properties for video editing. However I use only one single command line to reduce my video resolution. The code I added :

  LoadJNI vk = new LoadJNI();
  
                      try {
  
                          String workFolder = getApplicationContext()
  
                                  .getFilesDir().getAbsolutePath();
  
  
  
                          String[] complexCommand = {
  
                                  "ffmpeg",
  
                                  "-y",
  
                                  "-i",
  
                                  "/storage/emulated/0/DCIM/Camera/20150224_125355.mp4",
  
                                  "-strict", "experimental", "-s", "160x120",
  
                                  "-r", "25", "-vcodec", "mpeg4", "-b", "150k",
  
                                  "-ab", "48000", "-ac", "2", "-ar", "22050",
  
                                  "/storage/emulated/0/TempFolder/out.mp4" };
  
                          vk.run(complexCommand, workFolder,
  
                                  getApplicationContext());
  
  
  
                          Log.i("test", "ffmpeg4android finished successfully");
  
                      } catch (Throwable e) {
  
                          Log.e("test", "vk run exception.", e);
  
                      }

  To sum up, is there a way to import a portion of a project (as a module maybe) ? or do I have to find another method to reduce my video size ?
