## Installation

KnowIt can be installed as a regular python module by running:

$ [sudo] pip install knowit

For a better isolation with your system you should use a dedicated
virtualenv or install for your user only using the `--user` flag.

## External dependencies

KnowIt can use MediaInfo, ffprobe (FFmpeg) or mkvmerge (MKVToolNix)

KnowIt supports MKV regardless if MediaInfo, FFmpeg or MKVToolNix are
installed.

MediaInfo, FFmpeg or MKVToolNix increases the number of supported
formats and the number of extracted information.

MediaInfo is the default provider. Visit their
[website](http://mediaarea.net/MediaInfo) and install the proper package
for your system.

ffprobe (FFmpeg) can be downloaded
[here](https://ffmpeg.org/download.html)

mkvmerge (MKVToolNix) can be downloaded
[here](https://mkvtoolnix.download/downloads.html)
