Profile 8.2 Support

Add support for generating DV Profile 8.2 files (HEVC + SDR tonemap) - Dolby Vision HEVC bitstream
And how exactly? I have never seen profile 8.2 files.

That's not useful at all.
Reopen if you can find real world profile 8.2 video files.
Specifically, the section called "Encoding an SDR HEVC bitstream from a Dolby Vision mezzanine"

It is not what you want, it literally means encoding a normal SDR video, not a Dolby Vision Profile 8.2 video.
Hello,
I found that the x265, since version 3.0 , a new feature was added:
option:: ‘–dolby-vision-profile <integer|float>’ generates bitstreams confirming to the specified Dolby Vision profile. Currently only single-layer profiles are supported: profile 5, profile 8.1 and profile 8.2 enabled, Default 0 (disabled)
Also found a potential information on stitching the SDR + Dolby Vision files (SDR+RPU) here:
https://github.com/hybrik/hybrik-samples/tree/9a27f6ecd64ac52e96bae6aca86d74b3a7683874/Format%20Examples/Dolby%20Vision
An finally, they claim that if you use the mkv container and convert profile 5 to 8, and then inject the RPU, you'll get dolby vision profile 8.1, in case the video is HDR, or dolby vision profile 8.2 in case the video is SDR.
You're welcome to try Hybrik and generate a profile 8.2 video.
Like I said, if you can provide a sample then it can probably be supported.
