Comment:

 I can varify that you patch, Haihao, fixed the bug! I will attach the
 original file and fixed one. I am not sure whether it is a good idea to
 put data right behind "x265 (build 110) - 2.3:[Linux][GCC 5.4.0]" decoder
 info... But what do I know.

 hevc_metadata does not appear to be able to handle the file perfectly, it
 looks like it truncates some 00 00 00 01 from
