DefaultSurfaceTextureCaptureSource

class DefaultSurfaceTextureCaptureSource(logger: Logger, width: Int, height: Int, val contentHint: VideoContentHint = VideoContentHint.None, eglCoreFactory: EglCoreFactory) : SurfaceTextureCaptureSource

DefaultSurfaceTextureCaptureSource will provide a Surface which it will listen to and convert to VideoFrameTextureBuffer objects

Constructors

constructor(logger: Logger, width: Int, height: Int, contentHint: VideoContentHint = VideoContentHint.None, eglCoreFactory: EglCoreFactory)

Properties

contentHint

open override val contentHint: VideoContentHint

Content hint for downstream processing

minFps

open override var minFps: Int

Setting this to a positive value will lead the source to resend previously captured frames as necessary to approximately maintain the set value.

surface

open lateinit override var surface: Surface

Surface from which any buffers submitted to will be emitted as a VideoFrame. User must call start to start listening, and stop will likewise stop listening.

Functions

addCaptureSourceObserver

open override fun addCaptureSourceObserver(observer: CaptureSourceObserver)

Add a capture source observer to receive callbacks from the source on lifecycle events which can be used to trigger UI. This observer is entirely optional.

addVideoSink

open override fun addVideoSink(sink: VideoSink)

Add a video sink which will immediately begin to receive new frames.

release

open override fun release()

Deallocate any state or resources held by this object. Not possible to reuse after call. Surface will have been released.

removeCaptureSourceObserver

open override fun removeCaptureSourceObserver(observer: CaptureSourceObserver)

Remove a capture source observer

removeVideoSink

open override fun removeVideoSink(sink: VideoSink)

Remove a video sink which will no longer receive new frames on return

setMaxResolution

open override fun setMaxResolution(maxResolution: VideoResolution)

Set max resolution for video capture source DefaultCameraCaptureSource and DefaultScreenCaptureSource call this function to set max resolution for camera and screen capture

start

open override fun start()

Start capturing on this source and emitting video frames

stop

open override fun stop()

Stop capturing on this source and cease emitting video frames
