• Writing an MP4 header in Python [on hold]

  16 avril 2016, par Joe

  I have a script which downloads and concatenates a HLS/DASH stream encoded as MP4. However, as each stream file is a separate video chunk (as a .ts file), it isn’t a "proper" MP4 video when downloaded — even though VLC will play it, other programs won’t due to the lack of a header. Would there be a library or utility that will just write the header rather than spend time unnecessarily transcoding it ?

• Video streaming from file system

  20 novembre 2019, par shah ghani

  I am trying to make a video server, my scenario is users will upload there files and I have a screen that will play all the files of the day like advertisement that we usually watch in our televisions.

  So far I have achieved .hls and .flv streaming through node media server.

  I have found the best way to stream a file is through FFMPEG, but I am unable to stream multiple files on same output url for example localhost:8000/index.m3u8, Can any one suggest me the right way to stream the next file when FFMPEG ends streaming of a previous file.

  Thanks in advance. :)

  My node media service config

  {
  
    rtmp: {
  
      port: 1935,
  
      chunk_size: 60000,
  
      gop_cache: true,
  
      ping: 30,
  
      ping_timeout: 60
  
    },
  
    http: {
  
      port: 8000,
  
      mediaroot: './media',
  
      allow_origin: '*'
  
    },
  
    trans: {
  
      ffmpeg: 'E:/Red Matrix/node-stream-master/node-stream-master/usr/bin/ffmpeg.exe',
  
      tasks: [
  
        {
  
          app: 'live',
  
          hls: true,
  
          hlsFlags: '[hls_time=2:hls_list_size=3:hls_flags=delete_segments]',
  
          dash: true,
  
          dashFlags: '[f=dash:window_size=3:extra_window_size=5]'
  
        }
  
      ]
  
    }
  
  };

  FFMPEG stream function

  function ffmpegStream(stream){
  
  
  
    var proc = ffmpeg()
  
    .input('D:/Videos/1.MP4')
  
      .on('error', function (err) {
  
        console.log('An error occurred: ' + err.message);
  
      })
  
      .on('end', function (e) {
  
  
  
        console.log('Processing end !' + JSON.stringify(this));
  
  
  
         ffmpegStream('D:/Videos/2.MP4')
  
      })
  
      .on('done', function() {
  
        console.log('Processing finished !');
  
  
  
      })
  
      .save('./media/live/abc/index.m3u8');
  
  }

• mov : Support default-base-is-moof.

  1er juillet 2014, par Yusuke Nakamura

  mov : Support default-base-is-moof.
  default-base-is-moof shall be set to track fragments compatible with DASH
  
  Media Segments. So, this is a fundamental support for ISOBMFF ver. DASH.
  
  This is meaningful only when base-data-offset-present is absent and two or
  
  more track fragments are present in a movie fragment.
