Required Methods

fn create_player( &self, id: &ClientContextId, stream_type: StreamType, sender: IpcSender<PlayerEvent>, video_renderer: Option<Arc<Mutex<dyn VideoFrameRenderer>>>, audio_renderer: Option<Arc<Mutex<dyn AudioRenderer>>>, gl_context: Box<dyn PlayerGLContext>, ) -> Arc<Mutex<dyn Player>>

fn create_audiostream(&self) -> MediaStreamId

fn create_videostream(&self) -> MediaStreamId

fn create_stream_output(&self) -> Box<dyn MediaOutput>

fn create_stream_and_socket( &self, ty: MediaStreamType, ) -> (Box<dyn MediaSocket>, MediaStreamId)

fn create_audioinput_stream( &self, set: MediaTrackConstraintSet, ) -> Option<MediaStreamId>

fn create_videoinput_stream( &self, set: MediaTrackConstraintSet, ) -> Option<MediaStreamId>

fn create_audio_context( &self, id: &ClientContextId, options: AudioContextOptions, ) -> Result<Arc<Mutex<AudioContext>>, AudioSinkError>

fn create_webrtc(&self, signaller: Box<dyn WebRtcSignaller>) -> WebRtcController

fn can_play_type(&self, media_type: &str) -> SupportsMediaType

fn get_device_monitor(&self) -> Box<dyn MediaDeviceMonitor>

Provided Methods

fn set_capture_mocking(&self, _mock: bool)

fn mute(&self, _id: &ClientContextId, _val: bool)

Allow muting/unmuting the media instances associated with the given client context identifier. Backend implementations are responsible for keeping a match between client contexts and the media instances created for these contexts. The client context identifier is currently an abstraction of Servo’s PipelineId.

fn suspend(&self, _id: &ClientContextId)

Allow suspending the activity of all media instances associated with the given client context identifier. Note that suspending does not involve releasing any resources, so media playback can be restarted. Backend implementations are responsible for keeping a match between client contexts and the media instances created for these contexts. The client context identifier is currently an abstraction of Servo’s PipelineId.

fn resume(&self, _id: &ClientContextId)

Allow resuming the activity of all the media instances associated with the given client context identifier. Backend implementations are responsible for keeping a match between client contexts and the media instances created for these contexts. The client context identifier is currently an abstraction of Servo’s PipelineId.
