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.
pip install mpv...though you can also realistically just copy mpv.py into your project as it's all nicely contained in one file.
libmpv.so either locally (in your current working directory) or somewhere in your system library search path. This
module is somewhat lenient as far as libmpv versions are concerned but since libmpv is changing quite frequently
you'll only get all the newest features when using an up-to-date version of this module. The unit tests for this module
do some basic automatic version compatibility checks. If you discover anything missing here, please open an issue or
submit a pull request on github.
On Windows you can place libmpv anywhere in your %PATH% (e.g. next to python.exe) or next to this module's
mpv.py. Before falling back to looking in the mpv module's directory, python-mpv uses the DLL search order built
into ctypes, which is different to the one Windows uses internally. Consult this stackoverflow post for details.
We only support python stable releases from the last couple of years. We only test the current stable python release. If you find a compatibility issue with an older python version that still has upstream support (that is less than about four years old), feel free to open an issue and we'll have a look.
Linux, Windows and OSX all seem to work mostly fine. For some notes on the installation on Windows see this comment. Shared library handling is quite bad on windows, so expect some pain there. On OSX there seems to be some bug int the event logic. See issue 36 and issue 61 for details. Creating a pyQT window and having mpv draw into it seems to be a workaround (about 10loc), but in case you want this fixed please weigh in on the issue tracker since right now there is not many OSX users.

player.wait_for_playback()python-mpv mostly exposes mpv's built-in API to python, adding only some porcelain on top. Most "input commands" are mapped to methods of the MPV class. Check out these methods and their docstrings in the source for things you can do. Additional controls and status information are exposed through MPV properties. These can be accessed like player.metadata, player.fullscreen and player.loop_playlist.
The mpv module starts one thread for event handling, since MPV sends events that must be processed quickly. The
event queue has a fixed maximum 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.

player.wait_for_playback()The easiest way to load custom subtitles from a file is to pass the --sub-file option to the loadfile call:
#!/usr/bin/env python3
import mpv
player = mpv.MPV()
player.loadfile('test.webm', sub_file='test.srt')
player.wait_for_playback()Note that you can also pass many other options to loadfile. See the mpv docs for details.
If you want to add subtitle files or streams at runtime, you can use the sub-add command. sub-add can only be
called once the player is done loading the file and starts playing. An easy way to wait for this is to wait for the
core-idle property.
#!/usr/bin/env python3
import mpv
player = mpv.MPV()
player.play('test.webm')
player.wait_until_playing()
player.sub_add('test.srt')

Gtk.main()Just like it is possible to render into a GTK widget through X11 windows, it also is possible to render into a GTK widget using OpenGL through this python API.
Robozman has mangaed to make mpv render into a PyQt5/QML widget using OpenGL through this python API.
dfaker has written a demo (link) that uses mpv to render video into an imgui UI running on an OpenGL context inside GLFW. Check out their demo to see how to integrate with imgui/OpenGL and how to access properties and manage the lifecycle of an MPV instance.
Use pytest to run tests.
