First attempt at the FULL native Nuvio on Tizen 4.0/5.0/5.5 (2018-2020). Loading native code from the app folder is blocked on these TVs (UEP), so this build loads the library a different way — via memfd (syscall), with an in-memory ELF loader as fallback. @optiman's probe showed the mechanism should be allowed; this is the real app using it.
Very experimental. Two outcomes:
- It works: the real Nuvio opens (catalog, playback), same as the 6+ build.
- It doesn't: a black error screen with the failure messages — please photograph it and post to #137. That tells us exactly which load path the TV refused.
Install via Apps2Samsung (signs for your TV's DUID). For Tizen 6+ use native-tpk-preview.2 instead — this file is only for 2018-2020 TVs.
