How can I view/modify the header flags in an H264 file?

[bergqvistjl]

Is there a tool that lets me inspect and/or modify the header flags in an H264 file (specifically the flag specifying the colour range - full or limited), and if so, what are the flags that would specify that information, is it: video_full_range_flag, or are there others?

To see flag:
MediaInfo ("Color range: Full") or Codec Visa ("video_full_range_flag"==1 somewhere in the SPS->vui_parameters)

I don't see a 'color range' option in media info, the closest i've got is this:

Colorimetry : 4:2:0
Color space : YUV
Chroma subsampling : 4:2:0

If you don't see it it probably means that the full range flag is not set (i.e. it is implicitly limited range).

Very odd then. I was expecting it to be set....
