• 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.

  Revert "avcodec/mediacodecdec : wait on first frame after input buffers are full"
  @xyz reported a regression on his Sony Xperia Z3 Tablet Compact where
  
  playback would intermittently fail to start, essentially deadlocking in
  
  the decoder. Bisecting narrowed down the issue to this commit, which was
  
  meant as an optimization but is not necessary.
  This reverts commit a75bb5496ac6e7e194f1c6fd3b87f02a52e74adb.

• Encoding a readable movie by QuickTime using FFMPEG

  29 juillet 2018, par itamarb

  I’m trying to encode an image sequence using the following command :

  ffmpeg.exe -i %d.png -f mp4 -vcodec h264 test.mp4

  However, QuickTime failed to open this file or sometimes play a black movie, while this movie plays great in VLC player. Any suggestions how to make it play well in QuickTime ?

  Here is the output :

  ffmpeg.exe -i %d.png -f mp4 -vcodec libx264 13.mp4
