Class VideoFrameDrawer

java.lang.Object

tvi.webrtc.VideoFrameDrawer

public class VideoFrameDrawer
extends Object

Helper class to draw VideoFrames. Calls either drawer.drawOes, drawer.drawRgb, or drawer.drawYuv depending on the type of the buffer. The frame will be rendered with rotation taken into account. You can supply an additional render matrix for custom transformations.

drawTexture

public static void drawTexture(RendererCommon.GlDrawer drawer,
 VideoFrame.TextureBuffer buffer,
 android.graphics.Matrix renderMatrix,
 int frameWidth,
 int frameHeight,
 int viewportX,
 int viewportY,
 int viewportWidth,
 int viewportHeight)

Draws a VideoFrame.TextureBuffer. Calls either drawer.drawOes or drawer.drawRgb depending on the type of the buffer. You can supply an additional render matrix. This is used multiplied together with the transformation matrix of the frame. (M = renderMatrix * transformationMatrix)
