• Kodi : playback several video files from the internet as single movie with single timeline

  30 mai 2018, par HarryFox

  I’m writing an add-on for Kodi in Python, for a site with movie collection, which can be able to playback online video from the site. But problem is that many of them splitted apart on pieces of different length. And its not mpeg dash nor m3u playlists, its just individual pieces of single movie or an episode.

  My target is able to play those splitted videos as single movie with single timeline and playback will no require download all pieces of a movie. It’s important because many of Movies\episodes provides with subtitle file, that why single timeline is important. Also general idea for plugin which I’m writing is comfort to use, so online playback is very important too.

  I did some research but it almost no result. On official Kodi forum advise to create Input Stream add-on like Input Stream Adaptive, but it was written on c++ and it’s unattainable for me (for now at least). There is no tools for python to create such kind of add-ons.

  Another idea is to create middle server which on fly will somehow (with ffmpeg) combine those pieces, but it seems that the process will too resource-intensive especially for TV-boxes.
  In this case also raise many question about which way is better, and i have no enough experience and knowledge to solve the problems by myself even with google.

  So i need an advice how can i solve the problem, just to know right direction.
  Thank you for your time.
  Sorry for my English.

  Trivial for now, will become more useful in future commits, as many
  
  fields from FFFormatContext should not be visible to individual

• ffmpeg complex filter pip loop not working

  4 août 2021, par Dzseti

  I am using an ffmpeg complex filter to :

  


  

  1. turn a number of images into a slideshow

  


  2. scale the slideshow to 1/6th of its original size

  


  3. loop the slideshow infinitely

  


  4. set the looping slideshow as a picture-in-picture over another looping video

  


  


  then add audio from another file which determines the maximum length of the final video.

  


  Everything is working except step 3.

  


  Here is my code (broken down into individual lines) :

  


  ffmpeg -y
