The original implementation only allocates one segmentation map and this works fine for serial decode. But for frame parallel decode, each thread need to have its own segmentation map and the last frame segmentation map should be provided from last frame decoding thread. After finishing decoding a frame, thread need to serve the old segmentation map that associate with the previous decoded frame. The thread also need to use another segmentation map for decoding the current frame. Change-Id: I442ddff36b5de9cb8a7eb59e225744c78f4492d8
