 ### Changed
 
+- **`get_client_ip()` in `dispatcharr/utils.py` cleaned up.** Removed dead `.split(',')[0]` call and misleading variable name left over from a copy-paste of the `X-Forwarded-For` pattern. `X-Real-IP` is always a single IP (set by nginx from `$remote_addr`), so no splitting is needed. Behavior is unchanged.
 - **`ts_proxy` module refactored and renamed to `live_proxy`.** The live-streaming proxy was reorganized into a structured package (`apps/proxy/live_proxy/`) with explicit submodules for each stage of the pipeline: `input/` (HTTP streamer, stream manager, TS ring buffer), `output/ts/` (MPEG-TS client generator), `output/fmp4/` (fMP4 remux manager, Redis buffer, client generator), and `output/profile/` (output profile transcode manager). A dedicated `redis_keys.py` module centralizes all Redis key name construction for the proxy. Existing behavior for MPEG-TS clients is unchanged.
 - **XC API `allowed_output_formats` now includes `mp4`.** The `user_info` block returned by `player_api.php` and `get.php` previously advertised only `["ts"]`. It now advertises `["ts", "mp4"]` for all users, enabling XC-compatible clients that support fMP4 to request `.mp4` stream URLs which are proxied as fMP4.
 - **Browser preview URLs always force `mpegts` output.** The four in-app preview buttons (Channels table, channel stream list, Streams table, Stats client row) now append `?output_format=mpegts` (and the web player profile, if set) to the preview URL so the built-in `mpegts.js` player always receives a compatible stream, regardless of the user's configured default output format.
