Member Function Documentation

static Point org.webrtc.RendererCommon.getDisplaySize	(	ScalingType	scalingType,
		float	videoAspectRatio,
		int	maxDisplayWidth,
		int	maxDisplayHeight
	)

inlinestatic

Calculate display size based on scaling type, video aspect ratio, and maximum display size.

static float [] org.webrtc.RendererCommon.getLayoutMatrix	(	boolean	mirror,
		float	videoAspectRatio,
		float	displayAspectRatio
	)

inlinestatic

Returns layout transformation matrix that applies an optional mirror effect and compensates for video vs display aspect ratio.

static final float [] org.webrtc.RendererCommon.horizontalFlipMatrix ( )

inlinestatic

static final float [] org.webrtc.RendererCommon.identityMatrix ( )

inlinestatic

static float [] org.webrtc.RendererCommon.multiplyMatrices	(	float []	a,
		float []	b
	)

inlinestatic

Returns new matrix with the result of a * b.

static float [] org.webrtc.RendererCommon.rotateTextureMatrix	(	float []	textureMatrix,
		float	rotationDegree
	)

inlinestatic

Returns texture matrix that will have the effect of rotating the frame |rotationDegree| clockwise when rendered.

static final float [] org.webrtc.RendererCommon.verticalFlipMatrix ( )
