Python API to MPV using JSON IPC

Python MPV JSONIPC

This implements an interface similar to python-mpv, but it uses the JSON IPC protocol instead of the C API. This means you can control external instances of MPV including players like SMPlayer, and it can use MPV players that are prebuilt instead of needing libmpv1. It may also be more resistant to crashes such as Segmentation Faults, but since it isn't directly communicating with MPV via the C API the performance will be worse.

Please note that this only implements the subset of python-mpv that is used by plex-mpv-shim and jellyfin-mpv-shim. Other functionality has not been implemented.

Installation

sudo pip3 install python-mpv-jsonipc

Basic usage

Create an instance of MPV. You can use an already running MPV or have the library start a managed copy of MPV. Command arguments can be specified when initializing MPV if you are starting a managed copy of MPV.

Please also see the API Documentation.

from python_mpv_jsonipc import MPV

# Uses MPV that is in the PATH.
mpv = MPV()

# Use MPV that is running and connected to /tmp/mpv-socket.
mpv = MPV(start_mpv=False, ipc_socket="/tmp/mpv-socket")

# Uses MPV that is found at /path/to/mpv.
mpv = MPV(mpv_location="/path/to/mpv")

# After you have an MPV, you can read and set (if applicable) properties.
mpv.volume # 100.0 by default
mpv.volume = 20 

# You can also send commands.
mpv.command_name(arg1, arg2)

# Bind to key press events with a decorator
@mpv.on_key_press("space")
def space_handler():
    pass

# You can also observe and wait for properties.
@mpv.property_observer("eof-reached")
def handle_eof(name, value):
    pass

# Or simply wait for the value to change once.
mpv.wait_for_property("duration")
