Constructor Detail

FullFrameRect

public FullFrameRect(Texture2dProgram program)

Prepares the object.

Parameters:

program - The program to use. FullFrameRect takes ownership, and will release the program when no longer needed.

Method Detail

setUseMultiVideoview

public void setUseMultiVideoview(boolean bUse)

upDateVertexCoord

public void upDateVertexCoord(int imageWidth,
                              int imageHeight,
                              int viewWidth,
                              int viewHight,
                              VideoConstant.ScaleMode scaleType)

release

public void release(boolean doEglCleanup)

Releases resources.

This must be called with the appropriate EGL context current (i.e. the one that was current when the constructor was called). If we're about to destroy the EGL context, there's no value in having the caller make it current just to do this cleanup, so you can pass a flag that will tell this function to skip any EGL-context-specific cleanup.

getProgram

public Texture2dProgram getProgram()

Returns the program currently in use.

changeProgram

public void changeProgram(Texture2dProgram program)

Changes the program. The previous program will be released.

The appropriate EGL context must be current.

createTextureObject

public int createTextureObject()

Creates a texture object suitable for use with drawFrame().

drawFrame

public void drawFrame(int textureId,
                      float[] texMatrix,
                      int waterMarkTextureId)

Draws a viewport-filling rect, texturing it with the specified texture object.

drawFrame

public void drawFrame(int ytextureId,
                      int utextureId,
                      int vtextureId,
                      float[] texMatrix)

drawFrame

public void drawFrame(int textureId,
                      float[] texMatrix,
                      int waterMarkTextureId,
                      int ytextureId,
                      int utextureId,
                      int vtextureId)
