Add initial support for Subset SPS, Prefix NAL and Slice Extension NAL for non-base-view streams encoding, and the usual SPS, PPS and Slice NALs for base-view encoding. The H.264 Stereo High profile encoding mode will be turned on when the "num-views" parameter is set to 2. The source (raw) YUV frames will be considered as Left/Right view, alternatively. Each of the two views has its own frames reordering pool and reference frames list management system. Inter-view references are not supported yet, so the views are encoded independently from each other. Signed-off-by: Li Xiaowei <xiaowei.a.li@intel.com> [limited to Stereo High profile per the definition of MAX_NUM_VIEWS] Signed-off-by: Gwenole Beauchesne <gwenole.beauchesne@intel.com>
