Method Detail

isWZVideoFrameListenerActive

boolean isWZVideoFrameListenerActive()

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

Returns:

True if this listener is active; false otherwise.

onWZVideoFrameListenerInit

void onWZVideoFrameListenerInit(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 onWZVideoFrameListenerFrameAvailable(WOWZGLES.EglEnv, WOWZSize, int, long). See onWZVideoFrameListenerFrameAvailable(WOWZGLES.EglEnv, WOWZSize, int, long) for details.

onWZVideoFrameListenerFrameAvailable

void onWZVideoFrameListenerFrameAvailable(WOWZGLES.EglEnv eglEnv,
                                          WOWZSize frameSize,
                                          int frameRotation,
                                          long timecodeNanos)

Called after a frame has been rendered to the current OpenGL ES surface. The eglEnv may differ at each call but you can assume that the EGL context in each instance in between calls to onWZVideoFrameListenerInit(WOWZGLES.EglEnv) and onWZVideoFrameListenerRelease(WOWZGLES.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).

timecodeNanos - The frame timecode, in nanoseconds.

onWZVideoFrameListenerRelease

void onWZVideoFrameListenerRelease(WOWZGLES.EglEnv eglEnv)

Called at the end of a rendering cycle.

Parameters:

eglEnv - The current OpenGL ES environment.
