• Issue in concatenating two video files using FFMPEG

  12 mai 2014, par intrepidkarthi

  I am trying to concatenate two mp4 files taken from gallery. I am getting issue with process execution failure. I have added the code and the error log. Using the ffmpeg library taken from guardian project.

  I am running this in Samsung Galaxy S3 device.

  The error is thrown in this particular line.

  ProcessBuilder pb = new ProcessBuilder(cmds);
  
  pb.directory(fileExec);
  
  Process process = pb.start();  

  When I replace the last line above with this,

  Process process = Runtime.getRuntime().exec("chmod 777 "+cmds.toArray(new String[cmds.size()]));

  It works with out the exception as shown below. But the output doesn’t seem to come.

  File concatenation Code :

      File fileVideoOutput = new File(getApplicationContext()
  
              .getExternalFilesDir("test") + "hello.mp4");
  
      fileVideoOutput.delete();
  
  
  
      File fileTmp = getApplicationContext().getCacheDir();
  
      File fileAppRoot = new File(getApplicationContext()
  
              .getApplicationInfo().dataDir);
  
  
  
      try {
  
          FfmpegController fc = new FfmpegController(fileTmp, fileAppRoot);
  
  
  
          ArrayList<clip> listVideos = new ArrayList<clip>();
  
          Clip clip = new Clip();
  
          clip.path = video1;
  
          fc.getInfo(clip);
  
          clip.duration = clip.duration;
  
          System.out.println("Clip1 duration " + clip.duration);
  
          listVideos.add(clip);
  
  
  
          Clip clip2 = new Clip();
  
          clip2.path = video2;
  
          fc.getInfo(clip2);
  
          clip2.duration = clip2.duration;
  
          System.out.println("Clip2 duration " + clip2.duration);
  
          listVideos.add(clip2);
  
  
  
          Clip clipOut = new Clip();
  
          clipOut.path = fileVideoOutput.getCanonicalPath();
  
  
  
          fc.concatAndTrimFilesMP4Stream(listVideos, clipOut, 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);
  
                      }
  
                  });
  
      } catch (Exception e1) {
  
          e1.printStackTrace();
  
      }
  
  </clip></clip>

  Here is my ffmpeg commands as given in the ffmpeg tutorial page.

  ffmpeg -i input1.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate1.ts
  
  ffmpeg -i input2.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate2.ts
  
  ffmpeg -i "concat:intermediate1.ts|intermediate2.ts" -c copy -bsf:a aac_adtstoasc output.mp4

  FFMPEG library doesn’t seem to be working as expected. When I add commands and create output file using "touch" shell command file is being created. Still I am unable to see the output from ffmpeg as expected.

• Problems video playing in some android devices (version 4+) but not in others

  5 juin 2014, par anquegi

  following the settings for video in android developers, http://developer.android.com/guide/appendix/media-formats.html I encoded a video using ffmpeg like this :

  ffmpeg -i gravityTrailer.mp4 -y -f mp4 -vcodec libx264 -profile:v baseline -acodec aac    -strict -2  -profile:a aac_low -b:v 500k -ar 44100 -b:a 128k -ac 2 -r 30 -s 480x360  output_hq.mp4

  which corresponds on sd highquality in table 2 from android developers (link above).

  Then i put this video in a server and use the class android.media.MediaPlayer to reproduce it from that URL like this

  https://cloudapp.somedomain.com/bmftvideos/output_hq.mp4

  The problem is that the video is played on android version 4+

  you can see the video on :
  LG G2,
  Sony xperia S

  you cannot see the video on :
  Samsung galaxy S4,
  BQ (spanish) aquaris 4.5

  And I don not know why

  this is the ffmpeg output :
