SurfaceTextureHelper

open class SurfaceTextureHelper

Helper class for using a SurfaceTexture to create WebRTC VideoFrames. In order to create WebRTC VideoFrames, render onto the SurfaceTexture. The frames will be delivered to the listener. Only one texture frame can be in flight at once, so the frame must be released in order to receive a new frame. Call stopListening() to stop receiveing new frames. Call dispose to release all resources once the texture frame is released.

Types

FrameRefMonitor

interface FrameRefMonitor

Interface for monitoring texture buffers created from this SurfaceTexture.

Properties

val handler: Handler

open val isTextureInUse: Boolean

val surfaceTexture: SurfaceTexture

Functions

open fun create(threadName: String, sharedContext: EglBase.Context): SurfaceTextureHelper

Same as above with alignTimestamps set to false and yuvConverter set to new YuvConverter.

open fun create(threadName: String, sharedContext: EglBase.Context, alignTimestamps: Boolean): SurfaceTextureHelper

Same as above with yuvConverter set to new YuvConverter.

open fun create(threadName: String, sharedContext: EglBase.Context, alignTimestamps: Boolean, yuvConverter: YuvConverter): SurfaceTextureHelper

Create a SurfaceTextureHelper without frame ref monitor.

open fun create(threadName: String, sharedContext: EglBase.Context, alignTimestamps: Boolean, yuvConverter: YuvConverter, frameRefMonitor: SurfaceTextureHelper.FrameRefMonitor): SurfaceTextureHelper

Construct a new SurfaceTextureHelper sharing OpenGL resources with `sharedContext`.

open fun dispose()

Call disconnect() to stop receiving frames.

open fun forceFrame()

Forces a frame to be produced.

setFrameRotation

open fun setFrameRotation(rotation: Int)

Set the rotation of the delivered frames.

open fun setTextureSize(textureWidth: Int, textureHeight: Int)

Use this function to set the texture size.

open fun startListening(listener: VideoSink)

Start to stream textures to the given `listener`.

open fun stopListening()

Stop listening.

open fun ~~textureToYuv~~(textureBuffer: VideoFrame.TextureBuffer): VideoFrame.I420Buffer

Posts to the correct thread to convert `textureBuffer` to I420.
