• Transcoding rtsp over http

  24 novembre 2016, par NikiDon

  Before I explain my problem : Sorry for bad English and if you want you can help me on my spelling too.

  I have a low cost IP camera who give only a RTSP link :
  192.168.x.x/onvif2
  It doesn’t need authentication to see video... my router doesn’t have open ports^^

  I want to trancode rtsp ( because of html can’t play it) with FFMPEG to send it on a server node.js ( express ) and in index.html play stream in video tag :

  Server.js :

  <code class="echappe-js">&lt;script&gt;<br />
  
      var express = require('express');<br />
  
      var path = require('path');<br />
  
      var app = express();<br />
  
      var server = require('http').Server(app);<br />
  
      var io = require('socket.io')(server);<br />
  
  <br />
  
      app.use(express.static(path.join(__dirname, 'public')));<br />
  
  <br />
  
      app.get('/', function (req, res) {<br />
  
          res.sendFile(__dirname + '/index.html');<br />
  
      });<br />
  
  <br />
  
      server.listen(8080);<br />
  
      console.log(&quot;server run at 127.0.0.1:8080&quot;);<br />
  
  <br />
  
      io.on('connection',function(socket){<br />
  
          socket.emit('hello','hello user');<br />
  
      });<br />
  
  &lt;/script&gt;
  
  

  and index.html :

      <video style="background-color: black;" width="480" height="270" autoplay="autoplay">
  
      <source src="http://127.0.0.1:8080/vid2.mp4" type="video/mp4" codecs="avc1.42E01E, mp4a.40.2"> 
  
      </source></video>
  
  
  
      <code class="echappe-js">&lt;script&gt;<br />
  
          var socket = io.connect();<br />
  
          socket.on('hello',function(data){<br />
  
              console.log(data);<br />
  
          });<br />
  
  <br />
  
      &lt;/script&gt;
  ffmpeg -i rtsp ://192.168.x.x/onvif2 -crf 30 -preset ultrafast -acodec aac -strict experimental -ar 44100 -ac 2 -b:a 96k -vcodec libx264 -r 25 -b:v 500k -f flv http://127.0.0.1:xx/vid2.mp4
  
  
  

  The camera starts but I can’t find vid2.mp4

  How can I replace ffserver with a node server (http? udp ?...)

• Ffmpeg burnt in subtitles out of sync when converting to hls

  19 mai 2020, par user1503606

  I have a file that has subtitles burn into it and they are perfectly in sync.

  



  Here is the file. https://983yqbz442.s3.amazonaws.com/little-mermaid-captions.mp4

  



  I run this command to convert to hls and it creates the .ts files and the .vtt files.

  



  ffmpeg -i little-mermaid-captions.mp4 -profile:v baseline -level 3.0 -s 640x360 -start_number 0 -hls_time 10 -hls_list_size 0 -f hls index.m3u8


  



  I also then create a master.m3u8 file in the same folder with the following.

  



  #EXTM3U
#EXT-X-VERSION:3
#EXT-X-INDEPENDENT-SEGMENTS
#EXT-X-STREAM-INF:BANDWIDTH=800000,RESOLUTION=640x360,SUBTITLES="subtitles"
index.m3u8
#EXT-X-MEDIA:TYPE=SUBTITLES,GROUP-ID="subtitles",NAME="English",DEFAULT=YES,AUTOSELECT=YES,FORCED=NO,LANGUAGE="ENG",URI="index_vtt.m3u8"


  



  Now if I play the master.m3u8 file the subtitles are now out of sync and are about 1 sec to quick. I understand this is probably a setting I am missing through FFmpeg but really stuck on this and would appreciate any insight.

  



  Thanks

  



  More info.

  



  Here is a link to the direct .m3u8 this can be opened in Safari.

  



  https://983yqbz442.s3.amazonaws.com/hlstests/master.m3u8

  



  The generated vtt file is here.

  



  https://983yqbz442.s3.amazonaws.com/hlstests/subs-0.vtt

  



  If you look at the start of the .vtt file you will see this.

  



  WEBVTT

00:06.840 --> 00:10.320
once long ago in the deep blue below


  



  It should start at 00:06.840 but when playing the .m3u8 file in Safari you should see it starts at around 5 seconds not 6 about a second too early.
