Encoders may emit a buffering period SEI without a corresponding SPS/PPS if the SPS/PPS is carried out-of-band, eg with avcc. During Annex B conversion, this may result in the SPS/PPS being inserted *after* the buffering period SEI but before the IDR NAL. Since the buffering period SEI references the SPS, the SPS/PPS needs to come first. Signed-off-by: Anton Khirnov <anton@khirnov.net>
