Original commit message from CVS: * gst/h264parse/gsth264parse.c: (gst_nal_bs_init), (gst_h264_parse_sink_setcaps), (gst_h264_parse_chain_forward), (gst_h264_parse_queue_buffer), (gst_h264_parse_chain_reverse), (gst_h264_parse_chain): * gst/h264parse/gsth264parse.h: Parse codec_data and use the nalu_size_length field to get the NALU length in packetized h264. When queueing a packetized buffer in reverse mode, don't unref the buffer twice. Avoid accessing the buffer TIMESTAMP field after we pushed it on the adaptor.
