• Is there any way to stream video while encoding except using ffmpeg ?

  25 novembre 2016, par Ruslan Doronichev

  I am developing a cloud service, that allow users to upload video files from torrents and watch them online. In order to view the media, while transcoding - I convert the source file into hls format. I don’t really like this approach, as every user has a storage limit and he has to use his space for storing both hls and source files, even if he is not going to watch the video while encoding. What would be the best solution in this case ?

• SWF to PNG.. but merge all pngs inside into 1

  14 novembre 2014, par Jayden

  The title says it all,

  I’ve tried swftools and ffmepg but I don’t ’think’ they achieve what I need to do.

  Basically there is a SWF file that is made up of up to 60 images, them 60 images inside the SWF all are parts of an image that make up 1 final image or animation on an online game.

  I need to be able to download the swf as a png image with the same output it will look like on the virtual game - so not 60 images if seperate graphics, just one image with them all (merged ?) together.

  I am not even sure if this is possible to do in the commandline so if you understand any of this, please point me in the right direction.

  I am using Ubuntu 14.04

• How to set the destination folder of a Node.js fluent-ffmpeg screenshot to your AWS S3 bucket using getSignedUrl() ?

  10 juillet 2017, par Madhavi Mohoni

  I’m writing a program to generate .png thumbnails (with the same name, in the same folder) for a set of .mp4 videos in my Amazon S3 bucket. For this example, I’m going to create a /folder/file.png for a /folder/file.mp4 in the bucket. I’ve managed to set the source URL using the s3 object and getSignedUrl as follows :

  var srcurl = s3.getSignedUrl('getObject', {
  
          Bucket: 'bucket-name',
  
          Key: '/folder/file.mp4'
  
        });

  and

  new ffmpeg({ source: srcurl })
  
       .screenshots({
  
          count: 1, 
  
          filename: '%f'.substr(0, '%f'.indexOf('.')) + '.png', 
  
          /* To shorten the long string that's returned */ 
  
          folder: desturl,
  
          size: MAX_WIDTH + 'x' + MAX_HEIGHT
  
        });

  The destination URL has to be the same folder as the source. So I set it as follows :

  var desturl = s3.getSignedUrl('putObject', {
  
          Bucket: 'bucket-name',
  
          Key: '/folder/file' + '.png'
  
        });

  This combination doesn’t work - is there a way to do this correctly ?
