Method Detail

isWZVideoFrameRendererActive

boolean isWZVideoFrameRendererActive()

Checks whether the frame renderer is active. onWZVideoFrameRendererDraw(WOWZGLES.EglEnv, WOWZSize, int) will only be called on an active renderer.

Returns:

True if this renderer is active; false otherwise.

onWZVideoFrameRendererInit

void onWZVideoFrameRendererInit(WOWZGLES.EglEnv eglEnv)

Called at the beginning of a rendering cycle.

Parameters:

eglEnv - The current OpenGL ES environment, which may be a different EglEnv than the one supplied with each call to onWZVideoFrameRendererDraw(WOWZGLES.EglEnv, WOWZSize, int). See for onWZVideoFrameRendererDraw(WOWZGLES.EglEnv, WOWZSize, int) for details.

onWZVideoFrameRendererDraw

void onWZVideoFrameRendererDraw(WOWZGLES.EglEnv eglEnv,
                                WOWZSize frameSize,
                                int frameRotation)

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

Parameters:

eglEnv - The current OpenGL ES environment.

frameSize - The size of the video frame, in pixels.

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

onWZVideoFrameRendererRelease

void onWZVideoFrameRendererRelease(WOWZGLES.EglEnv eglEnv)

Called at the end of a rendering cycle.

Parameters:

eglEnv - The current OpenGL ES environment.
