• ffmpeg conversion x264 [error] : malloc of size 769152 failed

  18 décembre 2014, par prashanthp

  I am trying to convert video recorded from Android smart watch (.mp4 format) to a format (.mp4) which playable on all browsers. The video recorded from smart watch is not playing in the browsers. so, i’ve used ffmpeg to convert in into a playable mp4 format.

  But sometimes it is showing error as x264 [error]: malloc of size 503008 failed

  What is the reason for this. Sometimes it’s getting converted and sometimes it is showing error .

  Here is the console output.

• 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 ?
