I was struggling to burn the subtitles into the media file that I created from a DVD. Handbrake reads a DVD and write the content to an mpeg4 file. And this article explains how libdvdcss works. This article explains how to install this on Windows and OSX. To be able to decrypt DRM protected DVD’s (see above) also a free/libre DVD playback library libdvdcss is needed. These mpeg4 files can than be stored on the HDD of a device of your liking and played with any media player. Handbrake can, among other thing, read DVD’s and convert the content to e.g mpeg4 files. Most DVD’s are protected with DRM and some publishers like Disney take severe measurements to prevent the user from making a copy for their own use. For a few dollars/euros you can buy the best movies on DVD. DVD’s are cheap and second hand DVD’s are even cheaper. Use original DVD’sĭon’t use pirated DVD’s. ![]() In this post I’ll explain what you need to remove the DRM from DVD’s and copy the movie or TV series to OpenELEC or LibreELEC or any other system with Kodi e.g in your living room. Without the DRM the user can watch the content the way he/she prefers. Luckily this DRM can be removed with relatively simple means. DVD’s are an option but most of current DVD’s have strong DRM in place. Unfortunately the’re very little legal alternatives that respect the user rights. If you don’t believe me you can read it in the privacy statement of Netflix. This data is not only used to improve the service it can also be provided to third parties like law enforcement and other businesses for promotional ‘services’. Not only does Netflix use digital rights management (DRM) they also mine huge amounts of data from the users. What most people don’t know is that Netflix is trampling user rights. Why in this day and age of Netflix one would be interested in how to rip a DVD? More and more people are using Netflix or an other video streaming service to watch movies and TV series. To use the new palette with our mpeg video type: ffmpeg -i input.mp4 -i palette.png -r 12 -s 320x180 -filter_complex " paletteuse" prettyOutput.gif This is our newly created 256 color palette for our specific video which is generated by the palettegen filter. ![]() When we look in the folder of our mpeg file well noice that a file ‘palette.png’ has been added. To create this palette type: ffmpeg -i input.mp4 -filter_complex " palettegen" palette.png Luckily FFmpeg allows us to create a custom palette for our specific video. This is in general not optimal for the specific video that you want to convert. FFmpeg by default uses a generic palette of 256 colors that covers the widest range of content. Because GIFs only uses 256 colors the number of colors from the mpeg4 needs to be reduced. This is due to the default GIF encoding in FFmpeg. When we look closely at the resulting GIF we clearly notice some shortcomings in the animation. For the size of the GIF make sure that the aspect ratio remains the same or the resulting GIF will be distorted. This command reduces the framerate to 12 per second and resizes to 320×180 pixels. To achieve this we need the following command: ffmpeg -i input.mp4 -r 12 -s 320x180 output.gif In order to reduce the size of the file we can reduce the size of the images or we can reduce the number of frames per second. ![]() So you’ll end up with a file that’s much bigger than the original mpeg4 and probably something that exceeds the upload limit of Diaspora*, Friendica or Mastodon. Unfortunately gif images are large due to their lossless data compression. Where the name of the input file is input.mp4 and output.gif is the name of the output file. The basic command to create an animated GIF from a mpeg4 is: ffmpeg -i input.mp4 output.gif Below I will explain not only how to create a animated GIF from an mpeg4 movie but I also provide instructions to improve the quality. In fact suppose this post is more for users that like to tinker a lot with their animated GIFs. A word of warning FFmpeg is a command line tool that’s very versatile but it’s not for everybody. FFmpeg is available for Windows, Linux and OSX. FFmpeg is a good FLOSS tool to create these animated GIFs. ![]() Animated GIFs are after all these years still pretty popular. ![]()
