• 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

• Video editor application in android [on hold]

  26 janvier 2019, par Mustafa Çakar

  I want to make a video editor app, I also I want to add and remove text in the video. You can check renderforest video tab for example. I can use FFMPEG for basic editing operations like cropping, cutting, but I have no idea about set text or change text in the video. Do you have a source or library to suggest ? Sorry for my bad english.

• PHP-FFMpeg video output is truncated

  25 juin 2019, par showdev

  I’m using the PHP-FFMpeg library found here and code from the "Basic Usage" section.

  The outputted video seems to be truncated. I’m using a source video that’s 28 seconds long, but the output is only 9 seconds. What’s going wrong ?

  Here, I’m checking the duration of the source video :

  $ffprobe = FFMpeg\FFProbe::create();
  
  $duration = $ffprobe
  
    ->format('test/source.mp4')
  
    ->get('duration');

  28.700000

  Then generating an output video :

  $ffmpeg = FFMpeg\FFMpeg::create();
  
  $video = $ffmpeg->open('test/source.mp4');
  
  $video->save(new FFMpeg\Format\Video\X264(), 'test/export.mp4');

  Then checking the duration of the output video :

  $ffprobe = FFMpeg\FFProbe::create();
  
  $duration = $ffprobe
  
    ->format('test/export.mp4')
  
    ->get('duration');
