• Installing FFmpeg 1.1.2 "Fire Flower" on a mountain Lion

  14 février 2013, par Anand

  I am trying to install FFmpeg 1.1.2 "Fire Flower" on mountain lion machine.
  I downloaded http://www.ffmpeg.org/releases/ffmpeg-1.1.2.tar.bz2 from http://www.ffmpeg.org/download.html and extracted it.
  Is there a step by step tutorial to get the source code compiled, installed and get it running in my machine

• Web audio stream

  21 février 2013, par user658091

  What's a good solution for web audio streaming ?

  I've read about Flash Media Server, but that's a little too expensive right now, it seems easier than other solutions but can't afford it.

  There is FFmpeg, FFserver, Icecast and SSH among the popular.

  What I want is an easy solution for the user, which I was thinking something with flash. Load up FFmpeg/FFserver or Icecast as server stream and read that stream with a flash player inside the webpage. (I don't want to force users to download VLC or winamp)

  I'm not sure if I'm going the right way.

• Grab frame without downloading whole file ?

  12 janvier 2012, par Writecoder

  Is this possible using php + ffmpeg ?

  ffmpeg-php has the ability to :

  Ability to grab frames from movie files and return them as images that
  can be manipulated using PHP's built-in image functions. This is great
  for automatically creating thumbnails for movie files.

  I just don't want to download the whole file before doing so.
  So lets say i want to grab a frame @ 10% of the movie :

  First lets get the size of remote file :

  $ch = curl_init(); 
  
  curl_setopt($ch, CURLOPT_HEADER, true); 
  
  curl_setopt($ch, CURLOPT_NOBODY, true);
  
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 
  
  curl_setopt($ch, CURLOPT_URL, $url); //specify the url
  
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 
  
  $head = curl_exec($ch);
  
  
  
  $size = curl_getinfo($ch,CURLINFO_CONTENT_LENGTH_DOWNLOAD);

  Then it's quite easy to download only 10% of the .flv or .mov file using curl.

  But the framegrab trick using ffmpeg-php probably won't work because the file probably is corrupted ?

  Any other ideas ?
