Audio mixer API
If the mixer has problems during initialization it should raise mopidy.exceptions.MixerError with a descriptive error message. This will make Mopidy print the error message and exit so that the user can fix the issue.
Parameters: | config (dict) – the entire Mopidy configuration |
---|
Get mute state of the mixer.
MAY be implemented by subclass.
Return type: | True if muted, False if unmuted, None if unknown. |
---|
Get volume level of the mixer on a linear scale from 0 to 100.
Example values:
MAY be implemented by subclass.
Return type: | int in range [0..100] or None |
---|
Name of the mixer.
Used when configuring what mixer to use. Should match the ext_name of the extension providing the mixer.
Mute or unmute the mixer.
MAY be implemented by subclass.
Parameters: | mute (bool) – True to mute, False to unmute |
---|---|
Return type: | True if success, False if failure |
Set volume level of the mixer.
MAY be implemented by subclass.
Parameters: | volume (int) – Volume in the range [0..100] |
---|---|
Return type: | True if success, False if failure |
Send mute_changed event to all mixer listeners.
This method should be called by subclasses when the mute state is changed, either because of a call to set_mute() or because of any external entity changing the mute state.
Send volume_changed event to all mixer listeners.
This method should be called by subclasses when the volume is changed, either because of a call to set_volume() or because of any external entity changing the volume.
Marker interface for recipients of events sent by the mixer actor.
Any Pykka actor that mixes in this class will receive calls to the methods defined here when the corresponding events happen in the mixer actor. This interface is used both for looking up what actors to notify of the events, and for providing default implementations for those listeners that are not interested in all events.
