Can i mux the resulting h265 file into a mkv container?
Do i need to set DV Profile 8.1 to mux the additional layer?.

I am not sure what you are trying to do, but I am doubtful it would work
. Can you clearly define what your sources and desired outputs are? If you don’t already have an RPU file previously generated, you can’t do Profile 8.1. and there aren’t low-cost tools to generate one. ColorFront Transkoder is the most accesssble option I’m aware of.
Also, Profile 8.1 support isn’t common yet; the majority of existing Dolby Vision TVs in consumer hands today don’t support it. Profile 5 is what is universally supported.
The actual compression part is a relatively small and relatively straightforward part of making Dolby Vision content. Getting a properly shaped non-backwards compatible Y’CtCp source file and it’s metadata is the new and complex part.
Dolby Vision is a ways away from being something a consumer can make. It is totally feasible technically, but the tools just aren’t broadly available at this point.
