LIMITATIONS

Known limitations

- One byte window per request; a multi-range `Range` header is answered `416`. Browsers only ever ask a media element for one window. - `.mkv`, `.avi`, `.wmv`, `.flv` are claimed and listed, but Chromium cannot decode them; the plugin shows the player's error state rather than pretending they play. - No playlist, subtitle-track or speed controls of its own — the native controls own those. - If a deployment blocks the loopback origin (firewall, policy), the player falls back to the authenticated route automatically: the file still plays, but the desktop timeline is not seekable again. That is an Electron limitation ([electron#38749](https://github.com/electron/electron/issues/38749), [electron#51442](https://github.com/electron/electron/issues/51442)), not something the route can fix.
