    If installing via PyPi (Python Pip) on Linux then you need to know that VidCutter
    depends on the following packages, grouped by distro. Install using your
    Linux software packager for a noticeably better integrated experience.

        ---[Ubuntu/Debian/Mint/etc]--------------------------

            python3-dev libmpv1 libmpv-dev python3-pyqt5
            python3-pyqt5.qtopengl ffmpeg mediainfo

        ---[Arch Linux]--------------------------------------

            python mpv python-pyqt5 ffmpeg mediainfo

        ---[Fedora]------------------------------------------

            python3-devel mpv-libs mpv-libs-devel python3-qt5
            ffmpeg mediainfo

        ---[openSUSE]----------------------------------------

            python3-devel libmpv1 mpv-devel python3-qt5
            ffmpeg mediainfo 

    You need to build a Python extension module before you can run the
    app directly from source code. This is done for you automatically by
    the package installers but if you wish to simply run the app direct
    from source without having to install it (i.e. python3 setup.py install)
    you can do so by building the extension module with the following
    setuptools command, run from the top-most extracted source code folder:

        $ python3 setup.py build_ext -i

    And to then run the app directly from source, from the same top-most
    source code folder:

        $ python3 -m vidcutter

    To view all console output for debugging or general interest then
    append the debug parameter:

        $ python3 -m vidcutter --debug

    Make sure you build the extension module AFTER installing the
    dependencies covered above, in particular libmpv and the mpv + python3
    dev headers are all needed for it to compile successfully. Compiled
    extension modules under vidcutter/libs will look like:

        mpv.cpython-36m-x86_64-linux-gnu.so [linux]
        mpv.cp36-win_amd64.pyd              [win32]

    Windows users must do all this within a Visual Studio 2015/2017 Native x64/x86
    Developer Command Prompt accessible from your Visual Studio program group
    via the start menu. It's easier to just grab the prebuilt Windows installers
    directly from:
