• How to read percentage from ffmpeg command in java ?

  23 juillet 2019, par Prasab R

  I am trying to convert video file to specific format by executing ffmpeg command. In that process I want to read percentage by using timepattern format. Somehow I am not able to do it.

  I have tried using the below code. Specially I am getting null in the while loop condition.

  import java.io.*;
  
  import java.util.Scanner;
  
  import java.util.regex.Pattern;
  
  
  
  class Test {
  
    public static void main(String[] args) throws IOException {
  
      ProcessBuilder pb = new ProcessBuilder("ffmpeg","-i","in.webm","out.mp4");
  
      final Process p = pb.start();
  
  
  
      new Thread() {
  
        public void run() {
  
  
  
          Scanner sc = new Scanner(p.getErrorStream());
  
  
  
          // Find duration
  
          Pattern durPattern = Pattern.compile("(?<=Duration: )[^,]*");
  
          String dur = sc.findWithinHorizon(durPattern, 0);
  
          if (dur == null)
  
            throw new RuntimeException("Could not parse duration.");
  
          String[] hms = dur.split(":");
  
          double totalSecs = Integer.parseInt(hms[0]) * 3600
  
                           + Integer.parseInt(hms[1]) *   60
  
                           + Double.parseDouble(hms[2]);
  
          System.out.println("Total duration: " + totalSecs + " seconds.");
  
  
  
          // Find time as long as possible.
  
          Pattern timePattern = Pattern.compile("(?<=time=)[\\d.]*");
  
          String match;
  
          while (null != (match = sc.findWithinHorizon(timePattern, 0))) {
  
            double progress = Double.parseDouble(match) / totalSecs;
  
            System.out.printf("Progress: %.2f%%%n", progress * 100);
  
          }
  
        }
  
      }.start();
  
  
  
    }
  
  }

  I am expecting a value in the while condition, but it coming as null.enter code here

• how to fix "FFmpeg cannot edit existing files in-place."-Problem in Java

  7 juillet 2019, par Suione

  I am trying to write an audio file to an existing videofile. Unfortunately I get the Logmessage, that I cannot edit existing files in-place.

  I have found some threads about the so called muxing between video and audio, but none of them could help me out really. Maybe some one of you can.
  Further this isn`t my could either. I am only the one who needs to use it, so I have to fix it.

  Thanks for your help

  String[] args = { FFMPEG_FILE.getAbsolutePath(), "-y", "-i", videoPath, "-ss", String.valueOf(-offset.toFrames() / 50.0f), "-i", audioPath, "-c", "copy", "-map", "0:v", "-map","1:a", "-bsf:v", "h264_mp4toannexb","-r", String.valueOf(project.getFramerate()), "-shortest",outputPath };
  
  
  
  ProcessBuilder pb = new ProcessBuilder(args).inheritIO();
  
  Process p = pb.start();
  
  int exit = p.waitFor();
  
  if (exit != 0) {
  
       throw new IOException("ffmpeg terminated with a failure");
  
  }

  EDIT : As someone commented outputPath was same same as videopath. So switched it to another, so this problem would not appear again. But I still have no sound in my outputvideos. I give you the LOG-information, so maybe you can read something out of it.
