• Mix 2 audio files with android ffmpeg android

  15 novembre 2019, 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..

• Why does an "ffmpeg fail" occur when trying to export frames from my "data_src.mp4" file, while using DeepFaceLab ?

  28 août 2020, par Toby Ryberg

  I've been following this step-by-step videoin installing and using DeepFaceLab on my Macbook Pro, which uses OS Catalina. I've been stuck at the step which begins at the 4:42 mark, where he enters this code :

  


  python main.py videoed extract-video —input-file WORKSPACE/data_src.mp4 —output-dir WORKSPACE/data_src

  


  After entering the command, I'm prompted to enter an FPS value ; no problem. Next, it asks for a file output type, which is where I get tied up— as far as I know. It appears as though I can enter either png or jpeg, but receive the same error message, which looks like this :

  


  / !\ ffmpeg fail, job commandline :['ffmpeg', '-i', '/Users/tobyryberg/Documents/deepfakes/DeepFaceLab/WORKSPACE/data_src.mp4', '-pix_fmt', 'rgb24', '/Users/tobyryberg/Documents/deepfakes/DeepFaceLab/WORKSPACE/data_src/%5d.png']

  


  I have no idea what went wrong, as I BELIEVE that I have been doing everything right thus far. If this is at all necessary information, I've opted to use an 18+ minute long video for my source clip, which is an .mp4 file, without audio. If there's someone out there who has the patience to work with me and figure out what went wrong, I'll be forever grateful !
