Getting Started


You need at least an installed Java 8 or above to run the code. You can download it from


Just download the last release and extract it in a folder of your choice, then double click the EXE file.

One of the first things the application does is to download ffmpeg. You can speed up this progress by downloading it yourself and entering the location of the downloaded file in the init wizard.

Third Party Libraries


Application icons are from icons8. The flags in the README are from H. J. Nilsson.


To get the meta data from MP4 files, mp4parser is used. Since this library doesn't support reading chapter files (yet), I tried implementing it with the help of the official spec ("chpl" box, page 30).

Example files are from here.
