Flatpak or RPM ?, which is worth learning first ?

Hello All

So ive set myself the challenge of working within an EL7 only environment in my home lab and home workstation, i want to learn as much as possible about packaging.

It may be slightly over zealous of me being so new but i would like to package the things i need myself some examples are:

• MPV player
• Plex Media Player
• Lightworks
• OBS Studio

Just to name a few, im not a fan of adding 3rd party repos outside of EPEL and rpmfusion usually causes me multi version issues i don't think modular repositories has hit RHEL workstation yet.

My Question is am i best doing:

A: Build rpms from source and host my own repository for the software listed above

B: Building/Installing with flatpak and dodge possible version issues with dependencies either being to old or not available

Kind Regards

Ryan
