• Why is ffmpeg start time non-zero in .ts format?

  22 January 2014, by geekydel

  I'm using ffmpeg to transcode video to .ts format, and I am getting unexpected start times in the output file.

  To simplify things, I've started with a nice simple AVI file (no audio):

  ffmpeg -i in.avi 
  
  ...
  
  Input #0, avi, from 'in.avi':
  
    Metadata:
  
      encoder         : Lavf55.25.100
  
    Duration: 00:00:05.00, start: 0.000000, bitrate: 448 kb/s
  
      Stream #0:0: Video: mpeg4 (Simple Profile) (FMP4 / 0x34504D46), yuv420p, 480x270 [SAR 1:1 DAR 16:9], 24 tbr, 24 tbn, 24 tbc

  Duration=5s, startTime=0s, as expected.

  However, if I transcode to .ts file, with no customisation:

  ffmpeg -i in.avi -y out.ts
  
  ...
  
  Input #0, avi, from 'in.avi':
  
    Metadata:
  
      encoder         : Lavf55.25.100
  
    Duration: 00:00:05.00, start: 0.000000, bitrate: 448 kb/s
  
      Stream #0:0: Video: mpeg4 (Simple Profile) (FMP4 / 0x34504D46), yuv420p, 480x270 [SAR 1:1 DAR 16:9], 24 tbr, 24 tbn, 24 tbc
  
  Output #0, mpegts, to 'out.ts':
  
    Metadata:
  
      encoder         : Lavf55.25.100
  
      Stream #0:0: Video: mpeg2video, yuv420p, 480x270 [SAR 1:1 DAR 16:9], q=2-31, 200 kb/s, 90k tbn, 24 tbc
  
  Stream mapping:
  
    Stream #0:0 -> #0:0 (mpeg4 -> mpeg2video)
  
  Press [q] to stop, [?] for help
  
  frame=  120 fps=0.0 q=31.0 Lsize=     315kB time=00:00:04.95 bitrate= 519.9kbits/s dup=1 drop=0    
  
  video:277kB audio:0kB subtitle:0 global headers:0kB muxing overhead 13.491544%

  Then I get a very odd parameters (Duration=4:96s, startTime=1.441667):

  ffmpeg -i out.ts
  
  ...
  
  Input #0, mpegts, from 'out.ts':
  
    Duration: 00:00:04.96, start: 1.441667, bitrate: 519 kb/s
  
    Program 1 
  
      Metadata:
  
        service_name    : Service01
  
        service_provider: FFmpeg
  
      Stream #0:0[0x100]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p(tv), 480x270 [SAR 1:1 DAR 16:9], max. 104857 kb/s, 24 fps, 24 tbr, 90k tbn, 48 tbc

  Now, I can just about understand why the transcode might lose a couple of frames, which explains the duration, but I can't see why the start time should be any different to the AVI file's start time.

  I have tried transcoding to .mp4, .webm and .mov, and in each case we get the 'correct' start time of 0.0s. Can anybody help explain why .ts files behave differently?

  Thanks in advance!

• configure Xuggler on Ubuntu 14-04

  22 July 2015, by Aida

  I was trying to install Xuggle on Ubuntu with this tutorial

  But when I used ant stage it doesn`t work. I see these commands on the terminal

  > root@test1:~# ant stage Unable to locate tools.jar. Expected to find
  
  > it in /usr/lib/jvm/java-7-openjdk-amd64/lib/tools.jar Buildfile:
  
  > build.xml does not exist! Build failed

  Do you have any idea how I can fix it?

• Android FFMPEG java concat multiple files

  17 July 2015, by Kim T

  I’m using a fork of the cordova-plugin-video-editor library:

  https://github.com/jbavari/cordova-plugin-video-editor/pull/13

  Which uses the android-ffmpeg-java library here:

  https://github.com/guardianproject/android-ffmpeg-java

  The out of box cordova plugin example works well to encode a single video using the following code:

  File tempFile = File.createTempFile("ffmpeg", null, appContext.getCacheDir());
  
  FfmpegController ffmpegController = new FfmpegController(appContext, tempFile);
  
  
  
  TranscodeCallback tcCallback = new TranscodeCallback();
  
  
  
  Clip clipIn = new Clip(videoSrcPath);
  
  Clip clipOut = new Clip(outputFilePath);
  
  clipOut.videoCodec = "libx264";
  
  clipOut.videoFps = "24"; // tailor this to your needs
  
  clipOut.videoBitrate = 512; // 512 kbps - tailor this to your needs
  
  clipOut.audioChannels = 1;
  
  clipOut.width = outputWidth;
  
  clipOut.height = outputHeight;
  
  clipOut.duration = videoDuration;
  
  ffmpegController.processVideo(clipIn, clipOut, true, tcCallback);

  This calls the android-ffmpeg-java code here:

  https://github.com/guardianproject/android-ffmpeg-java/blob/master/src/org/ffmpeg/android/FfmpegController.java#L225

  They have a multiple file concat test example here:

  https://github.com/guardianproject/android-ffmpeg-java/blob/master/src/org/ffmpeg/android/test/ConcatTest.java#L16

  So I have modified the cordova plugin code to match the example:

  ArrayList<clip> listVideos = new ArrayList<clip>();
  
  
  
  Clip clip = new Clip();
  
  clip.path = new File(videoSrcPath).getCanonicalPath();
  
  ffmpegController.getInfo(clip);
  
  clip.duration = 5;
  
  listVideos.add(clip);
  
  
  
  Clip clip2 = new Clip();
  
  clip2.path = new File(videoSrcPath2).getCanonicalPath();
  
  ffmpegController.getInfo(clip2);
  
  clip2.duration = 5;
  
  listVideos.add(clip2);
  
  
  
  Clip clipOut = new Clip();
  
  clipOut.path = new File(outputFilePath).getCanonicalPath();
  
  ffmpegController.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);
  
      }
  
  });
  
  </clip></clip>

  However when run I get the error:
