• ffmpeg node js s3 stream screenshots qestion

  20 octobre 2015, par user3564443

  On my Node js server I need get video from s3, generate thumbnail for it, set thumbnail to s3, without saving video or thumbnail on my server. So I need to use streams for this. For thumbnail generation I use fluent-ffmpeg.

  Is it possible to get screenshots from streams using fluent-ffmpeg ?

  Is the correct way to intercept s3 getObject stream, that there was no need to download full video ?

  var config = require('../config');
  
  var AWS = require('aws-sdk');
  
  AWS.config.update({
  
    accessKeyId: config.AWS_accessKeyId,
  
    secretAccessKey: config.AWS_secretAccessKey,
  
    region: 'eu-west-1'
  
  });
  
  var s3 = new AWS.S3();
  
  var fs = require('fs');
  
  var ffmpeg = require('fluent-ffmpeg');
  
  
  
  exports.generateVideoThumbnail = function(fileId, url, done) {
  
    var params = {
  
      Bucket: config.AWS_bucket,
  
      Key: url
  
    };
  
    var input = s3.getObject(params);
  
    var stream = fs.createWriteStream('./screenshot.png');
  
    return ffmpeg(input).screenshots({
  
      timestamps: ['0.1', '0.2'],
  
      size: '200x200'
  
    }).output('./screenshot.png').output(stream).on('error', function(err) {
  
      return done(err);
  
    }).on('end', function() {
  
      input.close();
  
      var _key = "files/" + fileId + "/thumbnail.png";
  
      return s3.putObject({
  
        Bucket: config.AWS_bucket,
  
        Key: _key,
  
        Body: stream,
  
        ContentType: 'image/jpeg'
  
      }, function(err) {
  
        return done(err);
  
      });
  
    });
  
  };

• How to upload dynamically generated video thumbnails as a BLOB into MySQL database in PHP

  26 octobre 2018, par Parthapratim Neog

  Here is the code that has been used to create a thumbnail of a uploaded video. The thumbnail is automatically generated successfully, but now, I want to store that thumbnail as a BLOB in the Database.
  I know how to upload an image as a BLOB using form posts, but there is no form posts involved in this.

  Could someone guide me through this ?

   
  
  
  
  
  
   <form action="index.php" method="POST" enctype="multipart/form-data">
  
    <input type="file" />
  
    <input type="submit" value="Upload" />
  
   </form>
  
   &lt;?php
  
   if(isset($_POST['submit'])){
  
    /*
  
    -i input file name
  
    -an Disabled audio
  
    -ss Get image from x seconds in the video
  
    -s  size of the image
  
    */
  
    //Get one thumbnail from the video
  
    $ffmpeg = "C:\\ffmpeg\\bin\\ffmpeg";
  
    //echo $ffmpeg;
  
    $videoFile = $_FILES["file"]["tmp_name"];
  
    $imageFile = "1.jpg";
  
    $size = "120x90";
  
    $getFromSecond = 5;
  
  
  
    //echo "<pre>"; print_r($_FILES); die;
  
    //echo "video location: ",$videoFile,"<br />";
  
    echo $cmd = "$ffmpeg -i $videoFile -an -ss $getFromSecond -s $size $imageFile";
  
  
  
    echo "<br />";
  
    if(!shell_exec($cmd)){
  
     echo "Thumbnail Created!";
  
    }else{
  
     echo "Error creating Thumbnail";
  
    }
  
  
  
    /*// Get multiple thumbnails from one video
  
    $ffmpeg = "C:\\ffmpeg\\bin\\ffmpeg";
  
    $videoFile = $_FILES["file"]["tmp_name"];

     $interval = $num * 3;
  
     shell_exec("$ffmpeg -i $videoFile -an -ss $interval -s $size $num.jpg");
  
     echo "Thumbnail Created!- $num.jpg<br />";
