• Does ffmpeg support streaming links

  6 décembre 2013, par Jack Ben

  Suppose i've ffmpeg installed on my server so as far as i know that the following command

  <?PHP
  exec("ffmpeg -i video.avi -ar 22050 -ab 32 -f flv -s 320x240 video.flv");
  ?>
  

  so i wonder what if i can replace video.avi to streaming link like

  $link = "http://www.my_channels.com:33811";
  

  $link is streaming TV channel and i want to make it restreaming it as .flv so is it possible ! ~ Thanks
