  • Ffmpeg set duration using node-fluent-ffmpeg

    23 mai 2013, par Vprnl

    I'm really new to the world of ffmpeg so please excuses me if this is a stupid queston.

    I'm using the module Node-fluent-ffmpeg to stream a movie and convert it from avi to webm.
    So far so good (it plays the video), but I'm having trouble parsing the duration to the player. My ultimate goal is to be able to skip ahead in the movie. But first the player needs to know how long the video is.

    my code is as followed :

    var stat = fs.statSync(movie);
    

    
var start = 0;
    
var end = 0;
    
var range = req.header(&#39;Range&#39;);
    
if (range != null) {
    
start = parseInt(range.slice(range.indexOf(&#39;bytes=&#39;)+6,
    
  range.indexOf(&#39;-&#39;)));
    
end = parseInt(range.slice(range.indexOf(&#39;-&#39;)+1,
    
  range.length));
    
}
    
if (isNaN(end) || end == 0) end = stat.size-1;
    
if (start > end) return;
    

    
res.writeHead(206, { // NOTE: a partial http response
    
    &#39;Connection&#39;:&#39;close&#39;,
    
    &#39;Content-Type&#39;:&#39;video/webm&#39;,
    
    &#39;Content-Length&#39;:end - start,
    
    &#39;Content-Range&#39;:&#39;bytes &#39;+start+&#39;-&#39;+end+&#39;/&#39;+stat.size,
    
    &#39;Transfer-Encoding&#39;:&#39;chunked&#39;
    
});
    

    
var  proc = new ffmpeg({ source: movie, nolog: true, priority: 1, timeout:15000})
    
    .toFormat(&#39;webm&#39;)
    
    .withVideoBitrate(&#39;1024k&#39;)
    
    .addOptions([&#39;-probesize 900000&#39;, &#39;-analyzeduration 0&#39;, &#39;-bufsize 14000&#39;])
    
    .writeToStream(res, function(retcode, error){
    
    if (!error){
    
        console.log(&#39;file has been converted succesfully&#39;,retcode);
    
    }else{
    
        console.log(&#39;file conversion error&#39;,error);
    
    }
    
});

    I tried to set the header with a start and a end based on this article : http://delog.wordpress.com/2011/04/25/stream-webm-file-to-chrome-using-node-js/

    I also looked in the FFmpeg documentation and found -f duration and -ss.
    But I don't quite know how to convert the byte range to seconds.

    I feel like I'm pretty close to a solution but my inexperience with the subject matter prohibits me from getting it to work. If I'm unclear in any way please let me know. (I have a tendency of explaining things fuzzy.)

    Thanks in advance !
