• Use FFMPEG to put images separately inside a "box" and keeping their original positions of the X and Y boundaries and maybe modify their offsets

  14 septembre 2020, par karl-police

  I have a collection of images, for this example, I created 3 images that have different sizes, but the image itsself is the same, except it is moved more down or left or right.

  


  1 : 2 : 3 :

  


  These are the images. The total sizes of all images together is 35x39, so that means that they need to go inside an 35x39 image so it can later be used to craft them into a GIF as example. Since "crop" does not really work as it crops it smaller and can't make them bigger and I can't imagine it being the best solution for that anyway, perhaps.

  


  So this is the invisible 35x39 sized box.

  So what I'm trying to do is to figure out how I can put each of these images separately in the 35x39 sized box, but maintaining the original X position or the Y position or both, from the boundaries of the images. I'm trying to figure out how I can do this for other transparent images for similar things, mostly used to craft animations. Here into a GIF out of image collections, but the images need to be fixed first.

  


  I tried to look in the FFMPEG documentation, but there's many many filters and etc. that I had a few issues finding the right thing. I'm also not sure if it is also then possible to change the offset of the X and Y, because I think if there's something to make it keep the original position of X and Y, then I also think that there's probably something to change the offset of it aswell.

  


   

  


  End result of the images could basically be :

  


  1 : 2 : 3 :

  


  This end result example of the images, basically have their X aligned on the top and Y aligned on the left. I'm not sure if you can call it "original X position", because if I compare it to Photoshop's special paste and keep at original position, it puts the first image a bit more down as example, for some reason. So I just moved the X all the way to the top and the Y all the way to the left.

  


• Anomalie #3024 : spip_loader.php et IE8 (oui.... les pros du C/S traditionnels l’exigent !)

  26 janvier 2014, par Franck Dalot

  Bonjour
  Je l’ajoute à ce ticket, car il est possible que cela soit le même problème.

  Spip_loader ne fonctionne pas avec IE11, je viens de faire le test en php 5.4.21 chez OVH
  Je clique sur "commencer l’installation" et le pourcentage n’apparait même pas.
  A savoir que à la racine du site, j’ai la céation d’un dossier "SPIP-branche-3.0.zip" d’une taille de 9 253 006 octets et d’un dossier commençant par zip_

  Par contre, si je lance spip_loader avec firefox 26, je n’ai aucun problème.

  Il y a aussi des notices si j’ai configurer mes options, mais bon, ça c’est autre chose.

  Cordialement, Franck

• Piping to ffmpeg on windows

  8 septembre 2021, par Totte Karlsson

  I'm planning to pipe live image data (bitmaps) to ffmpeg in order to create an AVI file.

  



  Looking at the ffmpeg docs regarding pipes, https://ffmpeg.org/ffmpeg-protocols.html#pipe, it only mentions UNIX pipes.

  



  I'm planning using the technique described here : is it possible to send ffmpeg images by using pipe ?

  



  Is there a major difference on Windows that causes piping data to ffmpeg not working on Windows ?
