Edit max-cll metadata in hevc stream
Hi,
Anyone know if there's a way to edit the max-cll value from a hevc stream? I know FFmpeg as a hevc_metadata bitstream filter, but it doesn't seem to have the specific argument to modify this value. Thanks in advance |

Actually max-cll is only the option passed to x265, but when encoded they are two separate values:
- Max Content Light Level - Max Frame-Average Light Level There's a way to edit these values inside a mkv with mkvpropedit, but I'd rather edit then directly in the hevc stream |

That said, I'm not aware of any real-world player that uses MaxFALL, and only a few that use MaxCLL. Knowing the brightness of the brightest single pixel in a two hour movie really isn't that useful in figuring out how to tone map any given scene. |
