How playback works
Which copy plays, what a server converts and why, and the Info list.
Which copy plays
When a title has more than one copy (a 4K and a 1080p, a local file and a server's), Play chooses the one this device plays best: the picture it can decode and show, the sound it can play, the language you speak. A title's page lists every version with the recommended one marked and why. Always play this pins a version; Let Reflux choose gives the choice back.
The original, whenever it can be
Reflux plays your file as it is whenever the device can. When it cannot and the file is on a Jellyfin server, Reflux asks the server to change only what it must: the sound alone if only the sound is the problem, the picture only when the device cannot decode it. Local files and shares are played by the device alone; what it cannot play is said, not hidden.
Info
While something plays, the player's Info list says how it is playing: the original file or a conversion, the decoder in hardware or software, the sound, the subtitles, and whether that is what was planned.
Resuming
Progress belongs to the title, not the file: resume on any copy of the same cut, on any device that shares the source. A different cut (an extended edition) starts at the right place for it, and Reflux says so. From the start keeps your place until the new playback is under way.
Offline
Keep a film, an episode, or a season for watching without its source from its page. Downloads lists everything kept, on its way, or unfinished. Downloads continue while Reflux is open.
