smoothstreaming-fix-H264-CodecPrivateData-parsing-ne.patch

gstmssmanifest.c use function _gst_mss_stream_add_h264_codec_data() to parse
the H264CodecPrivateData. But gst_h264_video_calculate_framerate() might get
an incorrect framerate, because SPS NALU type(0x67) was forgot to skip by
using gst_h264_parse_sps() to do the parsing.
