PyObjC Framework - MediaPlayer

Warnings

• breaking PyObjC 12.0 dropped support for Python 3.9. Ensure your environment uses Python 3.10 or newer.
  Fix: Upgrade your Python interpreter to 3.10 or newer, or pin `pyobjc-framework-mediaplayer` to a version prior to 12.0 if you must use Python 3.9.
• breaking PyObjC 11.1 changed how initializer methods are handled, aligning with clang's Automatic Reference Counting (ARC) documentation. Methods in the 'init' family now correctly 'steal' a reference to self and return a new one. This can affect memory management and object lifecycles if your code relied on the previous behavior.
  Fix: Review any custom Objective-C classes implemented in Python or complex object instantiation patterns for correct reference counting, especially around 'init' methods.
• gotcha PyObjC 10.3 introduced a change preventing `__init__` from being called when a user-implemented `__new__` was present in a class or its superclasses. This was partially reverted in 10.3.1 to re-enable `__init__` use when a user implements `__new__`, but still prohibits it when relying on PyObjC's provided `__new__`.
  Fix: If experiencing issues with `__init__` and `__new__`, ensure your `__new__` implementation correctly handles object creation, and be aware that `__init__` might not be called in all scenarios where PyObjC provides the `__new__` method.
• gotcha The MediaPlayer framework on macOS requires specific user permissions (e.g., 'Media & Apple Music' access in System Settings > Privacy & Security). Your application might need to handle cases where these permissions are not granted, which can lead to silent failures or permission prompts.
  Fix: Inform users about required permissions and gracefully handle scenarios where access is denied. macOS will typically prompt the user for permission the first time your app attempts to access protected media.

Install

• pip install pyobjc-framework-mediaplayer Install MediaPlayer framework bindings

Imports

• MediaPlayer

  import MediaPlayer

  The framework is typically imported directly under its name.

Quickstart

This quickstart demonstrates how to interact with the macOS system music player using `pyobjc-framework-mediaplayer`. It attempts to find and play the first song in the user's Music library. Note that this requires macOS user permissions for 'Media & Apple Music' and actual music content in the Music.app.

import MediaPlayer
import time

# This example attempts to play a system music item.
# It requires user permission (Media & Apple Music access) and items in the Music library.
# On a system without Music.app or items, this might not do much visibly.

def play_music_item():
    player = MediaPlayer.MPMusicPlayerController.systemMusicPlayer()
    
    print(f"Initial playback state: {player.playbackState()}")

    query = MediaPlayer.MPMediaQuery.songsQuery()
    items = query.items()
    
    if items and len(items) > 0:
        first_item = items[0]
        print(f"Attempting to play: {first_item.title()} by {first_item.artist()}")
        player.setQueueWithItemCollection_(MediaPlayer.MPMediaItemCollection.collectionWithItems_([first_item]))
        player.play()
        print("Playback started. You might need to check your Music.app or system volume.")
        
        time.sleep(5) 
        player.pause()
        print("Playback paused after 5 seconds.")
    else:
        print("No music items found in the library or permissions not granted.")
        print("Please ensure Music.app has content and Python has access (System Settings > Privacy & Security > Media & Apple Music).")

if __name__ == "__main__":
    print("This script will attempt to use macOS's MediaPlayer framework.")
    print("It requires an active macOS system with the Music.app and potentially music items.")
    print("You might be prompted for Media & Apple Music access by macOS.")
