      net.java.sip.communicator.impl.neomedia.codec.video.FinalizableAVFrame

public class FinalizableAVFrame
extends AVFrame

Represents an AVFrame used to provide captured media data in native format without representing the very frame data in the Java heap. Since the user may not know when the AVFrame instances are really safe for deallocation, FinalizableAVFrame relies on the Java finalization mechanism to reclaim the represented native memory.
