• Resque does not find ffmpeg

  17 décembre 2012, par d33pika

  I am using resque to queue some encoding jobs. I have workers that pick up these jobs and do some transcoding.
  The issue is system "mencoder .." works fine but system "ffmpeg .." throws not found and the same to with system "qt-faststart .."
  I installed mencoder using sudo apt-get install.
  ffmpeg and qt-faststart were built from source.
  So mencoder was in /usr/bin and the other two in /usr/local/bin.
  So, the next thing I tried was using full path in the system command, that also returned not found.
  Then I copied ffmpeg and qt-faststart into /usr/bin.. Still got "Not Found"
  My worker code runs standalone but when god runs it, ffmpeg and qt-fasstart fail to execute. Yes, I have god configured to watch resque. Now, I don't know what else to try ! Any ideas ?

• Capture Thumbnail Whilte Downloading Youtube Video

  31 décembre 2012, par Minime

  I want to capture a thumbnail of Youtube video on certain timeline. (e.g. 3.2sec)
  I used ytdl and fluent-ffmpeg with node.js to implement it.
  It was possible to capture a thumbnail when the downloading has finished.

  var fs = require('fs');
  
  var ytdl = require('ytdl');
  
  var ffmpeg = require('fluent-ffmpeg');
  
  var videostream = fs.createWriteStream('video.flv');
  
  var myytdl = ytdl('http://www.youtube.com/watch?v=A02s8omM_hI');
  
  myytdl.pipe(videostream);
  
  videostream.on('close',function() {
  
    console.log('Downloading complete...');
  
    var proc = new ffmpeg({ source: 'video.flv', nolog: true })
  
    .withSize('150x100')
  
    .takeScreenshots(1, '/home/test', function(err) {
  
      console.log(err || 'Screenshots were saved');
  
    });
  
  });

  However, I couldn't implement to capture a thumbnail while downloading. Basic idea of what I want to do is as below.

  1. Download Youtube video starting at X sec. (Worked)
  2. Pipe it to Readable/Writable(Duplex) Memory Stream (Need Advise)
  3. During downloading, check if stream has enough data to capture the first frame, which is at X sec. (Need Advise)
  4. Capture the first frame, then stop downloading

  For 2, I've realized that node.js will have Duplex Stream on coming v0.9.x, but it seems not working properly. Anyone who has good idea to implement bullet 2,3 ?
