• ffmpeg watermark from java Runtime.exec cannot find output

  10 décembre 2013, par Rohi

  I'm having a problem in sending a ffmpeg command to add a watermark to my video from Java using Runtime.exec().
  The strange thing is that the same command is working perfectly from terminal....
  Any idea what the issue could be ?
  this is the command

  ffmpeg -i /home/mydir/inputvideo.mp4 -vf "movie=/home/mydir/watermarklogo.png [wm]; [in][wm] overlay=10:10 [out]" /home/mydir/outputvideo.mp4

  and this is the Java code (same as above, just wrapped in the exec code, and escaped characters

  Runtime rt = Runtime.getRuntime();
  
          Process proc = rt.exec("ffmpeg -i /home/mydir/inputvideo.mp4 -vf \"movie=/home/mydir/watermarklogo.png [wm]; [in][wm] overlay=10:10 [out]\" /home/mydir/outputvideo.mp4");
  
          InputStream stderr = proc.getErrorStream();
  
          InputStreamReader isr = new InputStreamReader(stderr);
  
          BufferedReader br = new BufferedReader(isr);
  
          String line = null;
  
          while ( (line = br.readLine()) != null)
  
              System.out.println(line);
  
          int exitVal = proc.waitFor();
  
          System.out.println("Process exitValue: " + exitVal);

  exit code is always 1 when running this.... this is the full output

• Java Playing Sound From YouTube

  8 mai 2022, par etkmlm

  I'm in a LWJGL game and want to play sound from YouTube. I have the stream link but can't play it anymore.

  


  public void playMusic(Music m) throws IOException {
    String uri = m.getUrl();
    URL url = new URL(uri);
    try{
        Process p = new ProcessBuilder().command("ffmpeg.exe", "-i", uri, "-acodec", "pcm_u8", "-ar", "22050", "-f", "wav", "pipe:1").redirectError(ProcessBuilder.Redirect.INHERIT).start();

        AudioInputStream str = AudioSystem.getAudioInputStream(p.getInputStream());
        Clip clip = AudioSystem.getClip();
        clip.open(str);
        clip.start();

    }
    catch (Exception e){
        e.printStackTrace();
    }

}


  


  It throws "Chunk size too big" error. I started ffmpeg alone but in this time, ffmpeg throws "invalid argumentsize=" error.

  


• Using Java and ffmpeg to most efficiently merge mp3 audio file and jpeg image file to a video file [closed]

  25 juin 2020, par Eugen

  I'm looking for an efficient way in Java to merge a large .mp3 file and a single .jpg image to a video format for youtube. If I use :

  


  ffmpeg -loop 1 -i image.jpg -i audio.mp3 -c:v libx264 -c:a aac -strict experimental -b:a 192k -shortest output.mp4


  


  the result is very slow, especially for large .mp3 files. Is it possible to do it more efficiently with ffmpeg ? I know there must be a way to do it much more efficiently, like all the online converters are doing it.
