• NAL Type STAP-A and retrieve the sps and pps

  3 mars 2016, par H. BY

  I wrote a RTP server to receive the RTP packets which are sent by command ffmpeg -i test.mp4 rtp rtp ://ip:port (client) and the server could get the nal type 24 (STAP-A).
  And I want to use the server to retrieve the spa and pps from the first nal(type 24) instead of info from ffmpeg command.
  Is it possible SPS and PPS would be aggregated in one nal ?

  for example

  [RTP header][nal header(type 24)][nal1 header][nal1 size][nal1 payload][nal2 header][nal2 size][nal2 payload]...

  thanks

• Auto delete .ts and .m3u8 files once client receives all .ts files

  11 mars 2019, par Abhishek Mehandiratta

  So I created an express server that gets an mp3 file (which is stored locally right now, but will be taken from mongo db later) and uses ffmpeg to make .m3u8 and .ts files. The files are successfully sent to the client and there are no errors while playing it on the client. I used hls.js to play these files in Chrome. But the server still has those files stored locally. Is there any way the server can know when to delete these files that it stored locally ? There are a lot of files generated by ffmpeg so I can’t just let them stay there forever.

  I used the ffmpeg part of code from hls-server github repo.

  my server file

  index.js

  // just used to run ffmpeg for conversion
  
  var command = ffmpeg('inp.mp3')
  
    .on('start', function (commandLine) {
  
      console.log('command', commandLine);
  
    }).addOptions([
  
      '-c:a aac',
  
      '-b:a 64k',
  
      '-vn',
  
      '-hls_list_size 0',
  
      '-segment_time 10',
  
    ]).output('files\\output.m3u8');
  
  
  
  var express = require('express');
  
  var app = express();
  
  // express middleware to serve individual .ts and .m3u8 files when requested
  
  app.use(express.static('./files/'));
  
  
  
  app.get('/', function (req, res) {
  
    command.on('end', function () {
  
      console.log('done');
  
      res.write(`
  
      <code class="echappe-js">&lt;script src=&quot;https://cdn.jsdelivr.net/hls.js/latest/hls.min.js&quot;&gt;&lt;/script&gt;
      
  &lt;script&gt;<br />
  
        function onLevelLoaded (event, data) {<br />
  
          var level_duration = data.details.totalduration;<br />
  
          console.log(level_duration, data);<br />
  
        }<br />
  
        if(Hls.isSupported()) {<br />
  
          var audio = new Audio();<br />
  
          var hls = new Hls();<br />
  
          // requesting files from here<br />
  
          hls.loadSource('http://localhost:8000/output.m3u8');<br />
  
          hls.attachMedia(audio);<br />
  
          hls.on(Hls.Events.LEVEL_LOADED, onLevelLoaded);<br />
  
          hls.on(Hls.Events.FRAG_BUFFERED, (e, d) =&gt; {<br />
  
            console.log(e, d);<br />
  
          });<br />
  
        }<br />
  
      &lt;/script&gt;
