Using libx265 no-repeat-headers option produces corrupt hevc file

Summary of the bug: passing no-repeat-headers to libx265 x265-params produces invalid hevc output.

How to reproduce:
My source is a h264 1080p mkv file. I use the command below as it is which produces an hevc that cannot be muxed or read by mediainfo nor mpc-be. Removing the no-repeat-headers parameter produces a good output file.
