• FFMpeg - move overlay from point a to b to c to d

  26 août 2017, par techr

  I used somebody else’s code posted by LordNeckbeard here : FFmpeg move overlay from one pixel coordinate to another

  I modified it a bit to this :

      ffmpeg -i 4632.mpg -i 4632.bmp -filter_complex "[0]scale=320:240[over];
  
      [1][over]overlay=enable='between=(t,0,50)':x=20+t*30:y=20+t*20" -s 
  
      1280:720 -c:a copy -y output.mpg

  I’d like to be able to limit the movement so the overlay does not go off screen.
  How can I move a scaled clip overlay in four directions, X & Y starting from originating location and back ?

• How to concatenate videos using FFMPEG in android using guardian project

  12 juin 2014, par Divya Motiwala

  I am trying to combine two mp4 videos using guardian project as library project in my app. But it does not generate the output at specified location. I went through various solution for it but no success.
  PFB the code :

  File fileTmp = this.getCacheDir(); 
  
  File fileAppRoot = new File(this.getApplicationInfo().dataDir);
  
  
  
  FfmpegController fc;
  
  
  
  fc = new FfmpegController(fileTmp, fileAppRoot);
  
  
  
  
  
  
  
      final Clip out = new Clip(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS)+"/Video/compiled.mp4");
  
  
  
      ArrayList<clip> listVideos = new ArrayList<clip>();
  
  
  
      File fileVideoRoot = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS)+"/Video");
  
      String[] fileList = fileVideoRoot.list();
  
  
  
      for (String fileVideo : fileList)
  
      {
  
          if (fileVideo.endsWith("mp4"))
  
          {
  
              Clip clip = new Clip();
  
              clip.path = new File(fileVideoRoot,fileVideo).getCanonicalPath();
  
  
  
              fc.getInfo(clip);
  
  
  
              clip.duration = clip.duration-1;
  
              listVideos.add(clip);
  
  
  
  
  
          }
  
      }
  
  
  
  
  
      fc.concatAndTrimFilesMP4Stream(listVideos, out, false, false, new ShellUtils.ShellCallback() {
  
  
  
          @Override
  
          public void shellOut(String shellLine) {
  
  
  
              System.out.println("fc>" + shellLine);
  
          }
  
  
  
          @Override
  
          public void processComplete(int exitValue) {
  
  
  
              if (exitValue &lt; 0)
  
                  System.err.println("concat non-zero exit: " + exitValue);
  
  
  
          }
  
      });
  
  </clip></clip>

  I am getting exception :

  There was a problem rendering the video :
  /mnt/sdcard/Download/Video/compiled.mp4

  Please guide me on how to concatenate videos in android.
