Proof

react-native-nitro-player

native-seam: the published 1.4.3 JS runs unchanged. PlayerQueue, TrackPlayer, DownloadManager, and Equalizer follow the iOS cores. AudioRoutePicker registers on iOS only and AudioDevices plus AndroidAutoMediaLibrary register on Android only. playback is one html audio element.

API coverage
No visual proof cases have been published for this package yet. The registry summary below describes what the compat layer implements.
Working
playlist CRUD, load, and Application Support persistence, play/pause/seek/skip with paused state, failed-item retry, request headers, repeat, volume, speed, up-next and play-next, lazy URL callbacks, equalizer bands, presets, and a 10-band peaking chain, downloads under Documents/NitroPlayerDownloads with progress and resume, simulated device storage totals
Missing
the route picker sheet, Android Auto stays disconnected, one element with no gapless preload, and a cross-origin source without CORS cannot feed the peaking chain so those gains stay silent
