10249	Using libx265 no-repeat-headers option produces corrupt hevc file	AYUSA		"**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.
