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 or FFmpeg (ffprobe)

KnowIt supports MKV regardless if MediaInfo or FFmpeg are installed.

MediaInfo or FFmpeg 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.

FFmpeg (ffprobe) can be downloaded here
