• 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 ?...)

• x264 Downsides of a high CRF (22) intermediary codec between conversions instead of lossless

  18 décembre 2019, par bobtheencoder

  I have a huge collection of video files that are in the range of CRF 16-20 taking up TB’s of space. The only need I have for these originals is that I have to encode them from time to time but the CRF of these final encodes is very low (CRF 26-28).

  I understand that a lossy to lossy converstion ALWAYS results in some quality loss but my question is what if the intermediate file is almost visually lossless compared to the final output.

  So to sum up, what quality difference should I expect from the following routes ?

  CRF 18 (original) -----> CRF 28 (final)
  
  CRF 18 (original) -----> CRF 22 (long-term storage) -----> Lossy  CRF 28 (final)
