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.
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 and install the proper package for your system.
ffprobe (FFmpeg) can be downloaded here
mkvmerge (MKVToolNix) can be downloaded here
