Method Summary

Modifier and Type	Method and Description
boolean	isWZVideoFrameRendererActive() Indicates if the frame renderer is active or not onWZVideoFrameRendererDraw(WZGLES.EglEnv, WZSize, int) will only be called on an active renderer
void	onWZVideoFrameRendererDraw(WZGLES.EglEnv eglEnv, WZSize frameSize, int frameRotation) Called to render a frame of video to the viewport for the current OpenGL ES context Note that eglEnv may differ at each call.

void	onWZVideoFrameRendererRelease(WZGLES.EglEnv eglEnv) Called at the end of a rendering cycle

Method Detail

isWZVideoFrameRendererActive

boolean isWZVideoFrameRendererActive()

Indicates if the frame renderer is active or not onWZVideoFrameRendererDraw(WZGLES.EglEnv, WZSize, int) will only be called on an active renderer

Returns:

true is this renderer is active, false otherwise.

onWZVideoFrameRendererInit

void onWZVideoFrameRendererInit(WZGLES.EglEnv eglEnv)

Called at the beginning of a rendering cycle

Parameters:

eglEnv - The current OpenGL ES environment. Note that this may be a different EglEnv than the one supplied with each call to onWZVideoFrameRendererDraw(WZGLES.EglEnv, WZSize, int). See for onWZVideoFrameRendererDraw(WZGLES.EglEnv, WZSize, int) for details.

onWZVideoFrameRendererDraw

void onWZVideoFrameRendererDraw(WZGLES.EglEnv eglEnv,
                                WZSize frameSize,
                                int frameRotation)

Called to render a frame of video to the viewport for the current OpenGL ES context Note that eglEnv may differ at each call. You can assume, however, that the EGL context in each instance in between calls to onWZVideoFrameRendererInit(WZGLES.EglEnv) and onWZVideoFrameRendererRelease(WZGLES.EglEnv eglEnv) are shared contexts and can access the same EGL resources.

Parameters:

eglEnv - The current OpenGL ES environment. Note that this may be a different EglEnv than the one supplied with

frameSize - size of the video frame (pixels)

frameRotation - frameRotation angle to apply when rendering (degrees, usually 0)

onWZVideoFrameRendererRelease

void onWZVideoFrameRendererRelease(WZGLES.EglEnv eglEnv)

Called at the end of a rendering cycle

Parameters:

eglEnv - The current OpenGL ES environment.
