• fluent-ffmpeg from an array of input files

  15 décembre 2016, par leonard vertighel

  I want to use fluent-ffmpeg to create a video of last n images of a directory, or database entries.

  Which is the correct syntax ?

  These are my tries :

  Mimic shell command

  ffmpeg()
  
    .addInput('ls *png | tail -n 17')
  
    .inputOptions("-pattern_type glob")
  
    .output("output.mp4").run()

  but it does not accept shell commands ;

  space - separated paths

  ffmpeg()
  
    .addInput('a*.png b*.png ')
  
    .inputOptions("-pattern_type glob")
  
    .output("output.mp4").run()

  but it does not accept list of files separated by spaces ;

  Array of image paths

  ffmpeg()
  
    .addInput(array) // ['aa.png', 'a1.png',,,'bbb.png']
  
    .inputOptions("-pattern_type glob")
  
    .output("output.mp4").run()

  but it does not accept arrays.

  EDIT :

  Also, from Merge Multiple Videos using node fluent ffmpeg, I am able to add multiple inputs using an array of files as

  var ffmpeg= require('fluent-ffmpeg');
  
  var f=ffmpeg() 
  
  pngarr.forEach(p => f.input(p)) /// pngarr is my array of png paths

  But running

  f.output("./output.mp4").run()

  I obtain just a video of 0 seconds containing the first png of the list.

• 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
