Camera & Microphone

The SDK does its best to make working with the camera and microphone easy. We expose the following objects on the call:

let call = streamVideo.call(callType: "default", callId: "123")
let camera = call.camera
let microphone = call.microphone
let speaker = call.speaker

Camera Manager

The following methods are available on the camera manager:

try await call.camera.enable() // enable the camera
try await call.camera.disable() // disable the camera
try await call.camera.flip() // switch between front and back camera

The camera manager also exposes these observables:

call.camera.direction // front/back
call.camera.status // enabled/ disabled.

Microphone Manager

The microphone manager supports changing the mic state:

try await call.microphone.enable() // enable the microphone
try await call.microphone.disable() // disable the microphone

You can get the microphone status like this:

call.microphone.status // enabled/ disabled.

You can also toggle the microphone state:

try await call.microphone.toggle()

Music mode

For music capture or higher-quality speech, select an audio bitrate profile after joining the call:

try await call.microphone.setAudioBitrateProfile(.musicHighQuality)

See the Music mode guide for dashboard requirements, voice profiles, and switching back to standard audio.

Noise Cancellation

Check our Noise Cancellation guide.

Speaker Manager

The speaker allows you to enable/disable the speaker phone.

try await call.speaker.enableSpeakerPhone()
try await call.speaker.disableSpeakerPhone()

Additionally, you can enable/disable the audio output on the device.

try await call.speaker.enableAudioOutput()
try await call.speaker.disableAudioOutput()

You can also toggle the speaker phone:

try await call.speaker.toggleSpeakerPhone()

Camera Focus and Zoom

The SDK provides methods to control camera focus and zoom during a call:

// Focus on a specific point (normalized coordinates 0-1)
try await call.focus(at: CGPoint(x: 0.5, y: 0.5))

// Zoom the camera (factor relative to current zoom level)
try await call.zoom(by: 2.0)

These features are useful for allowing users to focus on specific areas or zoom in during screen sharing or presentations.
