• ffmpeg : Streaming mpeg1 Video over HTTP Server

  23 juillet 2014, par user36685

  I ma trying to stream an mpg video over an http server using ffmepg. I initiate the ffserver and run the following command at the client :

  ffmpeg -i http://localhost:10212/Stream.mpg -y Sample.mpg

  I also tried the following but it did not also work :

  ffmpeg -i http://localhost:10212/Stream.mpg -b 2.6M -aspect "1280:720" -r 29 -g 29 -keyint_min 58 -ab 320000 -ar 48000 -ac 2 -f mpeg  "Sample.mpg" -vstats_file stats.txt

  But the Sample.mpg file is far less qualtiy and much smaller than the 480p.mpg file. I want the exact same 480p.mpg file with the same file size, bit rate, ratio, fps etc.

  My config file is as follow :

  <stream>
  
  
  
      File "/home/david/Documents/Video/Streaming/480p.mpg"
  
      format mpeg
  
  
  
      ACL allow 127.0.0.1
  
      ACL allow 192.168.1.0 192.168.1.255
  
  
  
  </stream>

• FFmpeg does not successfully send http request to server

  20 octobre 2019, par e-ly

  I’m trying to output data from ffmpeg to my webserver, but it simply does not work when I use my domain. It works as expected when I use localhost but not when I use my domain.

  I’ve tried multiple things such as changing from a subdomain to a subdirectory using nginx, and like I said— it works when I use localhost but not when I use my domain. When I ran -v trace the logs told me that the connection was successful but the server did not receive anything, yet when I visited the same url in my browser I got a response.

  ffmpeg command :

  '-v', 'trace',                                               
  
  '-f', 'x11grab',
  
  '-s', '720x480',
  
  '-r', '30',
  
  '-i', ':100',
  
  '-an',
  
  '-c:v', 'mpeg1video',
  
  '-q:v', '12',
  
  '-bf', '0',
  
  '-f', 'mpegts',
  
  'http://stream.domain.com/'                                                                                                    

  Nginx rule :

  server {
  
     listen 80;
  
     server_name stream.domain.com;
  
     location / {
  
         proxy_pass http://localhost:9000/;
  
     }
  
  }    

  Nodejs code :

  app.post('/', (req, res) => {
  
      console.log('Post received', req.url, req.ip)
  
      res.sendStatus(200)
  
  })

  I expect the console of the node process to let me know that a post has been received (for debugging purposes)
  Instead, nothing is received.
  However using http://localhost:9000/ instead of http://stream.domain.com/ works as expected
