-python-mpv is a ctypes-based python interface to the mpv media player. It gives you more or less full control of all features of the player, just as the lua interface does.

+===============================
+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.
+
+.. image:: https://github.com/McSinyx/comp/raw/master/doc/screenshot.png
+
+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``.
+
+Command line options
+--------------------
+
+::
+
+   usage: comp [-h] [-v] [-e {json,mpv,youtube-dl}] [-c CONFIG] [--vid VID]
+               [--vo DRIVER] [-f YTDL_FORMAT]
+               playlist
+
+   Curses Omni Media Player
+
+   positional arguments:
+     playlist              path or URL to the playlist
+
+   optional arguments:
+     -h, --help            show this help message and exit
+     -v, --version         show program's version number and exit
+     -e {json,mpv,youtube-dl}, --extractor {json,mpv,youtube-dl}
+                           playlist extractor, default is youtube-dl
+     -c CONFIG, --config CONFIG
+                           path to the configuration file
+     --vid VID             initial video channel. auto selects the default, no
+                           disables video
+     --vo DRIVER           specify the video output backend to be used. See
+                           VIDEO OUTPUT DRIVERS in mpv(1) for details and
+                           descriptions of available drivers
+     -f YTDL_FORMAT, --format YTDL_FORMAT
+                           video format/quality to be passed to youtube-dl
+
+Examples
+^^^^^^^^
+
+Open a JSON playlist::
+
+   comp -e json test/playlist.json
+
+Open a Youtube playlist with video height lower than 720::
+
+   comp -f '[height<720]' https://www.youtube.com/watch?list=PLnk14Iku8QM7R3ARnrj1TwYSZleF-i7jT
+
+Keyboard control
+----------------
+
+Return
+   Start playing.
+
+Space, ``p``
+   Toggle pause.
+
+``/``, ``?``
+   Search forward/backward for a pattern.
+
+``<``, ``>``
+   Go backward/forward in the playlist.
+
+``A``
+   Toggle mute.
+
+``D``
+   Delete the current entry.
+
+``N``
+   Repeat previous search in reverse direction.
+
+``V``
+   Toggle video.
+
+``W``
+   Save the current playlist under JSON format.
+
+``d``
+   Deselect/reselect the current entry.
+
+``i``
+   Insert playlist.
+
+``m``, ``M``
+   Cycle forward/backward through playing modes.
+
+``n``
+   Repeat previous search.
+
+``o``
+   Open playlist.
+
+Up, ``k``
+   Move a single line up.
+
+Down, ``j``
+   Move a single line down.
+
+Left, ``h``
+   Seek backward 5 seconds.
+
+Right, ``l``
+   Seek forward 5 seconds.
+
+Home
+   Move to the beginning of the playlist.
+
+End
+   Move to the end of the playlist.
+
+Page Up
+   Move a single page up.
+
+Page Down
+   Move a single page down.
+
+F5
+   Redraw the screen content.
+
+Configuration files
+-------------------
+
+If not specified by the ``--config``, (user-specific) configuration file is
+``~/.config/mpv/settings.ini``. Default configurations
+are listed below::
+
+   [comp]
+   # 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.

+.SH DESCRIPTION
+\fBcomp\fR is a 
+.BR mpv (1)
+front-end using curses. It has basic media player functions and can to extract

+.TP
+.B -v, --version
+show program's version number and exit
+.TP
+.B -e \fR{json,mpv,youtube-dl}, \fB--extractor \fR{json,mpv,youtube-dl}
+playlist extractor, default is \fIyoutube-dl
+.TP
+.B -c \fICONFIG, \fB--config \fICONFIG
+path to the configuration file
+.TP 
+.B --vid \fIVID
+initial video channel. \fIauto\fR selects the default, \fIno\fR disables video
+.TP
+.B --vo \fIDRIVER
+specify the video output backend to be used. See 
+.I VIDEO OUTPUT DRIVERS
+in
+.BR mpv (1)
+for details and descriptions of available drivers
+.TP 
+.B -f \fIYTDL_FORMAT\fR, \fB--format \fIYTDL_FORMAT
+video format/quality to be passed to youtube-dl

+.SH FILES
+.TP
+.I ~/.config/comp/settings.ini
+per user configuration file
+.SH EXAMPLES
+.nf R
+Open a JSON playlist:
+.ft B
+	comp -e json test/playlist.json
+
+.ft R
+Open a Youtube playlist with video height lower than 720:
+.ft B
+	comp -f '[height<720]' https://www.youtube.com/watch?list=PLnk14Iku8QM7R3ARnrj1TwYSZleF-i7jT
+.SH BUGS
+.PP
+Media durations are not extracted from online playlists as youtube-dl
+extract_flat option is used. This is rather a feature to save up bandwidth than
+a bug because a track's duration is updated when it's played.
