In some videos, SPS will be stored before VPS in hvcC box,
parse SPS does not depend on VPS, so the video is expected to be processed
normally.
Added "parsed_vps" parameter to indicate whether VPS have been parsed.
Only VPS have been parsed can be verified during SPS parsing.

eight times by default, even when this exceeds the recursion
