Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

mpv

  • There is no graphical interface at all by default, so a typical non-technical user will find it unusable without significant setup.
  • It has no library browser, artwork fetching or organised media collection view, unlike IINA or Infuse.
  • There is no Apple TV, iOS or Android version, so it cannot be used for a living room or mobile streaming setup.
  • Configuration is entirely file and flag based, so getting a specific behaviour set up correctly has a real learning curve compared with a settings panel.
  • Because it is a general-purpose engine rather than a consumer product, there is no dedicated support channel beyond community forums and documentation.

Rock RMS

  • Non-traditional pricing model based on donations rather than standard software licenses
  • Pricing based on self-reported average weekend attendance with honor system
  • Grant applications required for churches unable to afford donations
  • Cloud hosting fees may apply separately to donation amount
