• 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

• Convert .mov (ios7) to format playable on android 4.2.1

  29 novembre 2013, par user3048419

  I have got an iphone with ios7 and an android with 4.2.1. I want to take a video on the iphone and then play it later on the android. I am converting (via Ubuntu 13.04) the .mov video from the iphone into an mp4 format via the following (taken from Encoding video for Android) :

  avconv -i <input />.MOV -vcodec libx264 -profile:v baseline -b 500k -r 30 -vf "setsar=1:1" -acodec libvo_aacenc -ac 2 -ar 44100 -ab 128k <output>.mp4
  
  </output>

  Unfortunately <output>.mp4</output> does not seem to play on the android phone (android 4.2.1). Does anyone have any suggestions on how I can convert the .mov file into a format playable on android ?
