[FFmpeg-devel] [PATCH v2] lavc/hevc_ps: fix process failed when SPS before VPS in hvcC

[1035567130 at qq.com]

From: Wang Yaqiang <wangyaqiang03 at kuaishou.com>

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.
