  Add FATE test for matroska error recovery.
  This is the first 2 MB of the official test7.mkv.
  
  That length seems to be enough to detect the bugs
  
  we had in our code so far.

• 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.

• Ffmpeg color opacity

  19 janvier 2016, par Sandra

  I tried to rotate a video and keep the unused place due to the rotation transparent, to be able to overlay it later and to do that, I suppose that if the color was transparent is will be right ; and in the official page (https://www.ffmpeg.org/ffmpeg-filters.html#rotate) they said that you can give a color that ffmpeg would use in place of unused place due to the rotation of the video. So I tried, relatively to https://www.ffmpeg.org/ffmpeg-utils.html#Color to put a color with these commands

  ffmpeg -i video.mp4 -vf "rotate=PI/6:fillcolor=red@0.0" -acodec copy output.mp4

  and

  ffmpeg -i video.mp4 -vf "rotate=PI/6:fillcolor=red@0x00" -acodec copy output.mp4

  And it doesn’t work. The color remain opaque, and that whatever the value of the opacity (0.0 to 1.0)

  Any of you can know what is happened ?
