• working ffmpeg command fails when using in nginx with rtmp module

  7 juin 2017, par Rafael Linux User

  I have a tested code I did in a "bash" file. It works perfect on shell. I change only params to get it to work with nginx rtmp module, but ffmpeg says always and understandable error. This is the code :

  exec_push ffmpeg -re -y -i rtmp://localhost:1935/live/$name  \
  
                              -c:v libx264 -c:a aac  \
  
                              -g 24 -keyint_min 24   -preset veryfast -tune zerolatency -movflags +faststart -vsync passthrough  \
  
                              -filter_complex '[0:v]format=pix_fmts=yuv420p,split=3[in1][in2][in3];[in1]scale=320:-2[320x];[in2]scale=640:-2[HQ640x];[in3]scale=1280:-2[HD1280x];[0:a]aresample=44100[audio]'  \

                              -map '[HQ640x]'     -profile:v baseline -level 3.1 -crf 25 -maxrate 1000k -bufsize 1000k    -f mp4 rtmp://localhost:1935/rtmp_hls/$name_HQ640x  \
  
                              -map '[HD1280x]'    -profile:v main -level 3.1 -crf 19 -maxrate 4000k -bufsize 4000k        -f mp4 rtmp://localhost:1935/rtmp_hls/$name_HD1280x  \
  
                              -map '[audio]'      -b 128k                                                                 -f mp4 rtmp://localhost:1935/rtmp_hls/$name_audio 2>>/var/www/html/ffmpeg-live-output-$name.log;

  And this is the error launched by mmpeg

• Install ffmpeg in MAMP

  19 juin 2017, par David Liu

  I’m trying to use this : https://www.youphptube.com/ to create a video sharing website.

  I’m developing locally using MAMP on macOS Sierra and have installed both ffmpeg and exiftool on the system, but how do I make it work from within the server ? Under "Advanced Configuration" what do I put in "Path to FFMPEG" and "Path to exiftool" ? What is the folder this path is relative to ? I guess this is why the videos I try to upload never start encoding. In "Leave blank for native ffmpeg" what does "native ffmpeg" mean ?

  I already tried putting the absolute paths but it doesn’t work either. I’m getting this error log :

  [19-Jun-2017 13:59:13 America/Panama] "status" :"error", "msg" :["sh : ffprobe : command not found"] ,"return_val":127, "where" :"getDuration", "cmd" :"ffprobe -i /Applications/MAMP/tmp/php/phpq2j0pt -sexagesimal -show_entries format=duration -v quiet -of csv=’p=0’"
  [19-Jun-2017 13:59:13 America/Panama] Duration founded : EE:EE:EE
  [19-Jun-2017 18:59:14 UTC] rm -f /Applications/MAMP/htdocs/platea-3/videos/video2_59481f01ed6179.69459230.jpg && ffmpeg -ss 5 -i /Applications/MAMP/htdocs/platea-3/videos/original_video2_59481f01ed6179.69459230 -qscale:v 2 -vframes 1 -y /Applications/MAMP/htdocs/platea-3/videos/video2_59481f01ed6179.69459230.jpg
  Array
  (
  [0] => sh : ffmpeg : command not found
  )

  So basically I think the server doesn’t find neither ffmpeg nor ffprobe.

  I would appreciate it if someone could take the time to install it as well and take a look. Thanks !

• Java Xuggler Metadata List of Chapters MP4/M4V Video

  27 juin 2017, par MrSax

  I’m trying to use Xuggler like FFMPEG Metadata Wrapper (I just need the list of Chapters of MP4/M4V Video).

  So far I have not been able to find a solution.
  Can anyone help me ?

  I was only able to get the following information :

      final String filename = "...path...";
  
      IContainer container = IContainer.make();
  
      int result = container.open(filename, IContainer.Type.READ, null);
  
      if (result < 0)
  
          throw new RuntimeException("Failed to open media file");
  
      int numStreams = container.getNumStreams();
  
      long duration = container.getDuration();
  
      long fileSize = container.getFileSize();
  
      long bitRate = container.getBitRate();
  
      System.out.println("Number of streams: " + numStreams);
  
      System.out.println("Duration (ms): " + duration);
  
      System.out.println("File Size (bytes): " + fileSize);
  
      System.out.println("Bit Rate: " + bitRate);
  
      for (int i = 0; i < numStreams; i++) {
  
          IStream stream = container.getStream(i);
  
          IStreamCoder coder = stream.getStreamCoder();
  
          System.out.println("*** Start of Stream Info ***");
  
          System.out.printf("stream %d: ", i);
  
          System.out.printf("type: %s; ", coder.getCodecType());
  
          System.out.printf("codec: %s; ", coder.getCodecID());
  
          System.out.printf("duration: %s; ", stream.getDuration());
  
          System.out.printf("start time: %s; ", container.getStartTime());
  
          System.out.printf("timebase: %d/%d; ", stream.getTimeBase().getNumerator(),
  
                  stream.getTimeBase().getDenominator());
  
          System.out.printf("coder tb: %d/%d; ", coder.getTimeBase().getNumerator(),
  
                  coder.getTimeBase().getDenominator());
  
          System.out.println();
  
          if (coder.getCodecType() == ICodec.Type.CODEC_TYPE_AUDIO) {
  
              System.out.printf("sample rate: %d; ", coder.getSampleRate());
  
              System.out.printf("channels: %d; ", coder.getChannels());
  
              System.out.printf("format: %s", coder.getSampleFormat());
  
          } else if (coder.getCodecType() == ICodec.Type.CODEC_TYPE_VIDEO) {
  
              System.out.printf("width: %d; ", coder.getWidth());
  
              System.out.printf("height: %d; ", coder.getHeight());
  
              System.out.printf("format: %s; ", coder.getPixelType());
  
              System.out.printf("frame-rate: %5.2f; ", coder.getFrameRate().getDouble());
  
          }
  
          System.out.println();
  
          System.out.println("*** End of Stream Info ***");

  UPDATE 07.06.2017
  I just tried it with VLCJ, but still I can not get the list of chapters.

      File file = new File("ia_ISL_13_r720P.m4v");
  
  
  
      NativeLibrary.addSearchPath(RuntimeUtil.getLibVlcLibraryName(), "vlc64/");
  
      Native.loadLibrary(RuntimeUtil.getLibVlcLibraryName(), LibVlc.class);
  
  
  
      MediaPlayerFactory mpf = new MediaPlayerFactory();
  
      EmbeddedMediaPlayer emp = mpf.newEmbeddedMediaPlayer();
  
  
  
      MediaMeta mediaMeta = mpf.getMediaMeta(file.getAbsolutePath(), true);
  
      MediaMetaData asMediaMetaData = mediaMeta.asMediaMetaData();
  
      System.out.println(asMediaMetaData.getAlbum());
  
      System.out.println(asMediaMetaData.getArtist());
  
      System.out.println(asMediaMetaData.getTitle());
  
  
  
      emp.prepareMedia(file.getAbsolutePath());
  
      emp.play();
  
      emp.nextChapter(); // -> GO NEXT CHAPTER - SUCCESS
  
  
  
      List> allChapterDescriptions = emp.getAllChapterDescriptions();
  
  
  
      for (List<string> list : allChapterDescriptions) {
  
          for (String string : list) {
  
              System.out.println(string);
  
          }
  
      }
  
  </string>
