It gives you more or less full control of all +features of the player, just as the lua interface does. + +Installation +------------ + +.. code:: bash + + wget -O mpv.py https://raw.githubusercontent.com/jaseg/python-mpv/master/mpv.py + +Seriously though, part of the idea of this being all in one handy file is that you can just copy it into your project. +That also means you don't need to be afraid of customizing it, as it's really not a lot of code. + +Usage +----- + +.. code:: python + + import mpv + player = mpv.MPV(ytdl=True) + player.play('https://youtu.be/DOmdB7D-pUU') + + +Threading +~~~~~~~~~ + +The ``mpv`` module starts one thread for event handling, since MPV sends events that must be processed quickly. The +event queue has a fixed maxmimum size and some operations can cause a large number of events to be sent. + +If you want to handle threading yourself, you can pass ``start_event_thread=False`` to the ``MPV`` constructor and +manually call the ``MPV`` object's ``_loop`` function. If you have some strong need to not use threads and use some +external event loop (such as asyncio) instead you can do that, too with some work. The API of the backend C ``libmpv`` +has a function for producing a sort of event file descriptor for a handle. You can use that to produce a file descriptor +that can be passed to an event loop to tell it to wake up the python-mpv event handler on every incoming event. + +All API functions are thread-safe. If one is not, please file an issue on github. + +Advanced Usage +~~~~~~~~~~~~~~ + +.. code:: python + + #!/usr/bin/env python3 + import mpv + + def my_log(loglevel, component, message): + print('[{}] {}: {}'.format(loglevel, component, message)) + + player = mpv.MPV(log_handler=my_log, ytdl=True, input_default_bindings=True, input_vo_keyboard=True) + + # Property access, these can be changed at runtime + player.observe_property('time-pos', lambda pos: print('Now playing at {:.2f}s'.format(pos))) + player.fullscreen = True + player.loop = 'inf' + # Option access, in general these require the core to reinitialize + player['vo'] = 'opengl' + + def my_q_binding(state, key): + if state[0] == 'd': + print('THERE IS NO ESCAPE') + player.register_key_binding('q', my_q_binding) + + player.play('https://youtu.be/DLzxrzFCyOs') + player.wait_for_playback() + + del player + +.. code:: python + + #!/usr/bin/env python3 + import mpv + + player = mpv.MPV(ytdl=True, input_default_bindings=True, input_vo_keyboard=True) + + player.playlist_append('https://youtu.be/PHIGke6Yzh8') + player.playlist_append('https://youtu.be/Ji9qSuQapFY') + player.playlist_append('https://youtu.be/6f78_Tf4Tdk') + + player.playlist_pos = 0 + + while True: + # To modify the playlist, use player.playlist_{append,clear,move,remove}. player.playlist is read-only + print(player.playlist) + player.wait_for_playback() + +Coding conventions +------------------ + +The general aim is `PEP 8`_, with liberal application of the "consistency" section. 120 cells line width. Four spaces. +No tabs. Probably don't bother making pure-formatting PRs except if you think it *really* helps readability or it +*really* irks you if you don't. + +.. _`PEP 8`: https://www.python.org/dev/peps/pep-0008/ -- cgit
