+# iptv-downloader
+
+A lightweight HTTP server for browsing and downloading content from an Xtream Codes IPTV provider. Written in C, zero runtime dependencies beyond libcurl and pthreads.
+
+## Features
+
+- Browse series and movies by category
+- Full-text search across the entire catalogue
+- Sequential download queue with progress tracking, speed and ETA
+- Resume interrupted downloads; skip already-downloaded files
+- Discord webhook notifications on completion or failure
+- Jellyfin library refresh triggered after each successful download
+- Notification history with dismiss support
+- Runtime configuration — no recompile needed to change provider or paths
+
+## Requirements
+
+- GCC, make
+- libcurl (development headers)
+- Linux (uses `SO_BINDTODEVICE` for VPN binding)
+
+## Build
+
+```sh
+make
+make test    # optional — runs unit tests
+```
+
+## Install
+
+```sh
+sudo make install
+# installs binary to /usr/local/bin/iptv-dl
+# installs static files to /usr/local/share/iptv-dl/{css,js,html}/
+```
+
+## Configuration
+
+Create a config file at one of the following locations (first found wins):
+
+1. Path passed via `--config PATH`
+2. `$IPTV_DL_CONFIG` environment variable
+3. `~/.iptv-downloader/config.json`
+4. `/etc/iptv-downloader/config.json`
+5. Built-in defaults (runs without any config file)
+
+Example config:
+
+```json
+{
+  "port": 8787,
+  "bind_iface": "wg0-mullvad",
+  "iptv_api": "http://your.provider/player_api.php",
+  "iptv_user": "username",
+  "iptv_pass": "password",
+  "stream_base": "http://your.provider:80",
+  "dl_dir_tv": "/mnt/media/TV",
+  "dl_dir_mov": "/mnt/media/Movies",
+  "discord_webhook": "",
+  "jellyfin_url": "",
+  "jellyfin_token": "",
+  "template_dir": "/usr/local/share/iptv-dl",
+  "data_dir": "/var/lib/iptv-dl",
+  "max_recv_speed": 20971520
+}
+```
+
+Print the active config:
+
+```sh
+iptv-dl --dump-config
+```
+
+## Source layout
+
+```
+config/         Runtime configuration (load/save/defaults)
+util/           String buffer, JSON parser, URL/HTML/JS escaping
+http/           HTTP request parsing, response helpers, route handlers
+notifs/         Notification ring buffer with persistence
+queue/          Download queue, worker thread, history, Xtream Codes API client
+integrations/   Discord webhook, Jellyfin library refresh
+static/css/     Stylesheet
+static/js/      Shared JS (BASE, filter, dlMov), downloads page, series selector
+static/html/    Page header and footer templates
+tests/          Unit tests
+main.c          Server entry point (~80 lines)
+```
+
+## Usage
+
+```sh
+iptv-dl [--config PATH] [--dump-config]
+```
+
+The web UI is served at `http://localhost:8787/`. If running behind a reverse proxy at a sub-path (e.g. `/iptv/`), all asset and navigation links are relative and work correctly.
