I've never packaged before, but took a stab at packaging MakeMKV.
It seems to install/run as expected on my local system, but the packaging may very well not be done correctly. (For example, I patched the makemkv-bin Makefile to stop the EULA-prompt from interrupting the build.)
Any feedback would be much appreciated.
