Where each one falls short

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

IINA

  • There is no Apple TV or iOS app, so it cannot be used for a living room streaming setup the way Infuse can.
  • It has no polished network share or cloud storage library browser, so streaming from a NAS or cloud drive is more manual than with Infuse.
  • As a volunteer open source project, new feature development and bug fixes depend on contributor availability rather than a funded team.
  • It is Mac only, so there is no equivalent app for Windows users in a mixed household.
  • Advanced mpv configuration is still exposed for power users, which can be confusing for someone who just wants simple playback with no options.

Unreal Engine

  • 5% royalty triggered on any project exceeding $1 million in gross revenue across all revenue sources
  • Smaller mobile game ecosystem compared to Unity, with fewer optimized mobile libraries and live-ops services
