comp - Curses Omni Media Player
===============================

**comp** is a `mpv <https://mpv.io/>`_ front-end using curses. It has basic
media player functions and can to extract playlists from multiple sources such
as media sites supported by `youtube-dl <https://rg3.github.io/youtube-dl/>`_,
local and direct URL to video/audio and its own JSON playlist format.

Installation
------------

**comp** requires Python 3.5+ with ``curses`` module (only available on
Unix-like OSes such as GNU/Linux and the BSDs) and ``libmpv`` (available as
``libmpv1`` in Debian/Ubuntu, openSUSE; and as ``mpv`` in Arch Linux, Gentoo,
macOS Homebrew repository). It also depends on ``python-mpv`` and
``youtube-dl`` but the setup program will automatically install them if they
are missing.

As ``setuptools`` will `install in an egg and cause breakage
<https://github.com/McSinyx/comp/issues/5>`_, using ``pip`` (Python 3 version) 
is a must.  After `installing it <https://pip.pypa.io/en/latest/installing/>`_,
run ``pip3 install comp`` (you might want to add ``--user`` flag to use the
`User Scheme <https://pip.pypa.io/en/stable/user_guide/#user-installs>`_).

For developers, clone the `Github repo <https://github.com/McSinyx/comp>`_ then
simply run the ``comp`` executable to test the program. If you insist on
installing it, still use ``pip3``: ``pip3 install .``. Note that **comp** is
distibuted in a ``wheel`` created via ``./setup.py bdist_wheel``.

   # Initial playing mode, which can be one of these 8 modes: play-current,
   # play-all, play-selected, repeat-current, repeat-all, repeat-selected,
   # shuffle-all and shuffle-selected.
   play-mode = play-current

   [mpv]
   # Initial video channel. auto selects the default, no disables video.
   video = auto
   # Specify the video output backend to be used. See VIDEO OUTPUT DRIVERS in
   # mpv(1) man page for details and descriptions of available drivers.
   video-output =

   [youtube-dl]
   # Video format/quality to be passed to youtube-dl. See FORMAT SELECTION in
   # youtube-dl(1) man page for more details and descriptions.
   format = best


Bugs
----

Media durations are not extracted from online playlists as
``youtube-dl.YoutubeDL`` option ``extract_flat`` is set to ``'in_playlist'``.
This is rather a feature to save up bandwidth than a bug because a track's
duration is updated when it's played.
