...muxed a short sample of Saving Private Ryan to single track dual layer FEL, then I demuxed and converted it to MEL ...It plays perfectly on my M9702 and looks the same as the original complete UHD BluRay backup.
Thank you for your time. Thanks to your tests it seems to me that "method 2" is safe and functional.
Before releasing version v0.0.4_BETA I need one last test: an STDL FEL-> MEL file inside the MKV container (to be tested on a device like the FireStick 4K, capable of playing MEL profile 7 but not FEL profile 7 ). Of course you have to use my version of ExoP.
Always using the various conversion steps FEL -> MEL, instead of creating an m2ts MEL DTDL in TsMuxeR, generate an ISO (always adding first BL.hevc and then EL_RPU.hevc in TsMuxeR) and feed it to MakeMKV.

If I use TsMuxeR to mux 'BL_EL_RPU.hevc' which is in dv 8 profile with Dts audio tracks, TsMuxer switches me back to dv 7 profile, and it is read in HDR PQ and not in Dolby Vision.
............
I would like to have a .ts with a dv 8 profile
thanks
This behavior is normal. If you give TsMuxeR a raw hevc stream consisting of BL+EL+RPU, TsMuxer will only be able to assign profile 7.
Do you want profile 8? You have to import a stream with only BL+RPU into TsMuxeR. To do this, right click on "MUX.bat" and "MUX_AND_CONVERT_TO_MEL.bat" and then select "Edit". Add the string
-mode 2 in both and save the changes. At the moment, however, I do not recommend proceeding with this solution. Read on to understand why.
PS:
the name of the file created will always be BL_EL_RPU.hevc but it is simply a placeholder for people who are "too lazy"
to use the command line

if you're looking for a new project, I would love an RPU parser(supported by x265.exe) just like the HDR10+ parser does so I can encode uhd-BD to true profile 5 full range.

True profile 5, that's what I am waiting for...
I honestly don't understand why you guys care so much about profile 5.
It uses a proprietary color space (the advantages of which will perhaps be appreciable when we have 12bit panels) and not having an Enhancement Layer is definitely lower quality than a UHD-BD. So why?
Converting a color space involves an encoding operation, and if you wait for me to write an encoder from scratch then the wait will be very long (years).
I'm sure there are people in the world who are already working on it. I don't have the skills for that!
Instead I am doing some experiments on profile 8 (in particular 8.1). The idea is to improve my -mode 2 (UHD-BD -> 8.1). This profile should work for any "streaming device" (from televisions to consoles). What do you think?

Good evening yusesope, how do you get the RPU out of the EL? it is to be able to encode afterwards in x265
thank you

x265 does not need a parser for RPU. It simply accepts a file containing the RPUs (I presume sorted according to each access unit present in the Base Layer). Look
HERE.
What's the problem? If you proceed with an encoding of the Base Layer then you must also change the parameters of the RPU. At the moment, however, we do not know the algorithm that allows to generate new RPUs!
