Struct medea_jason::media::MediaManagerHandle

pub struct MediaManagerHandle(_);

External handle to a MediaManager.

MediaManager performs all media acquisition requests (getUserMedia()/getDisplayMedia()) and stores all received tracks for further reusage.

MediaManager stores weak references to local::Tracks, so if there are no strong references to some track, then this track is stopped and deleted from MediaManager.

Implementations

impl MediaManagerHandle

pub async fn enumerate_devices( &self ) -> Result<Vec<MediaDeviceInfo>, Traced<EnumerateDevicesError>>

Returns a list of platform::MediaDeviceInfo objects representing available media input and devices, such as microphones, cameras, and so forth.

Errors

See EnumerateDevicesError for details.

pub async fn enumerate_displays( &self ) -> Result<Vec<MediaDisplayInfo>, Traced<EnumerateDisplaysError>>

Returns a list of platform::MediaDisplayInfo objects representing available displays.

Errors

See EnumerateDisplaysError for details.

pub async fn init_local_tracks( &self, caps: MediaStreamSettings ) -> Result<Vec<LocalMediaTrack>, Traced<InitLocalTracksError>>

Returns local::LocalMediaTracks objects, built from the provided MediaStreamSettings.

Errors

See InitLocalTracksError for details.

pub async fn set_output_audio_id( &self, device_id: String ) -> Result<(), Traced<InvalidOutputAudioDeviceIdError>>

Switches the current audio output device to the device with the provided device_id.

Errors

With InvalidOutputAudioDeviceIdError if the provided device_id is not available.

pub async fn set_microphone_volume( &self, level: i64 ) -> Result<(), Traced<MicVolumeError>>

Sets the microphone volume level in percents.

Errors

See MicVolumeError for details.

pub async fn microphone_volume_is_available( &self ) -> Result<bool, Traced<HandleDetachedError>>

Indicates whether it’s possible to access microphone volume settings.

Errors

If the underlying MediaManagerHandle is dropped.

pub async fn microphone_volume(&self) -> Result<i64, Traced<MicVolumeError>>

Returns the current microphone volume level in percents.

Errors

See MicVolumeError for details.

pub fn on_device_change( &self, cb: Function<()> ) -> Result<(), Traced<HandleDetachedError>>

Subscribes onto the devicechange event of this MediaManagerHandle.

Errors

If the underlying MediaManagerHandle is dropped.
