Setup

Tell the service about your portal and how you want it to run. Saving writes stalker-plexer.conf into the data directory; from then on that file wins over the environment variables, and the service restarts for a moment to pick it up.

Note: stalker-plexer.conf is present in the data directory — saving will update it

Portal account

Portal base URL Your provider's portal base URL (the one your MAG box is set up with). Required. Whitelisted MAC The MAC address your account is tied to. Required. Emulated device model The MAG box this service impersonates. Defaults to MAG250. Verified models: MAG250, MAG254, MAG322, MAG323, MAG324, MAG342, MAG400, MAG410, MAG520, MAG620, MAG7100. Other models probably work.

Service

Stream mode proxy = play through this server's /live proxy (recommended, self-heals stale lines); direct = raw provider URLs in the M3U. Channel lineup

How the lineup is served:

full — default. Every channel the provider pulls is served.
customized — serve only the channels you tick on the Channels page. The HDHomeRun device count, the M3U and the EPG all follow your selection. Until you first save a selection there, every channel is still served.

Public host Host name or IP the players (Plex, Jellyfin) use to reach this service — its LAN IP or Docker service name. Keep it bare (optionally host:port for a public port different from the service's); the service adds http:// and its own port. A pasted http:// URL is trimmed, never doubled. Chunk size Channels per TVChannels-NN.m3u playlist (the full TVChannels.m3u is always exported as well). ffmpeg (re-encode binary) ffmpeg re-encodes every /live channel to a clean H.264 + MP2 MPEG-TS for Plex's HDHomeRun tuner (MP2 because Plex's decoder-less transcoder cannot read AAC-in-ADTS). Leave empty to look for ffmpeg on the PATH. Channels without ffmpeg keep serving their raw upstream (m3u8 for HLS), which VLC and M3U players can play. Re-encode backend

Which encoder re-encodes every /live channel to H.264 + MP2 for Plex's HDHomeRun tuner. Pick by your hardware:

auto — default. Try a GPU first, then fall back to CPU. Leave it here unless you have a reason to pin.
qsv — Intel GPU / iGPU (Quick Sync).
vaapi — AMD GPU, or Intel via VAAPI.
nvenc — NVIDIA GPU (NVENC). The linux/amd64 image ships ffmpeg built with h264_nvenc — map the GPU in with --gpus all (NVENC is x86-only, so it is not on the arm64 image).
v4l2m2m — Linux V4L2 stateless encoders on SoCs / embedded GPUs: this is the one that works on a Raspberry Pi (its VideoCore/VEC H.264 encoder — 64-bit OS), and on Rockchip / Amlogic / Allwinner / Qualcomm / MediaTek SoCs. Not for discrete NVIDIA cards (that is nvenc).
cpu — encode on the CPU with libx264. Always works, no GPU needed (about one core per 720p channel).
off — no re-encode; serve the raw upstream (Plex then shows "Could not tune" on most channels).

A GPU / hardware backend only works if the container can actually reach the device — map it in (Intel/AMD: --device /dev/dri; NVIDIA: --gpus all; a V4L2 SoC such as a Raspberry Pi: the codec's /dev/videoN — e.g. /dev/video11 on a Pi 4). A pinned backend the container can't reach silently falls back to CPU (with a log warning).

HDHomeRun & discovery

HDHomeRun DVR APIServe the native HDHomeRun device API (/ch/NN/…) so Plex can find and play the lineup without Threadfin/xTeVe. HDHR tuners per device How many tuners each HDHomeRun device reports — Plex allows this many simultaneous streams per device. HDHR model number The model string reported per device (cosmetic, e.g. HDTC2-1ST). SSDP discoveryAdvertise the HDHomeRun device on the LAN via SSDP/UPnP so Plex auto-discovers it (turn off inside Docker if Plex cannot hear multicast).

Schedule & maintenance

EPG refresh (hours) How often the service refreshes the guide data. Keep it under your provider's typical ~5 h EPG window. Channel re-pull (hours) How often the full channel list is re-pulled (backstop; the watchdog renews the stream line on demand). Watchdog (minutes) How often the watchdog probes the stream line and self-heals a stale one. 0 disables it. Pull on scheduleWhen off, the service serves the exported files as they are and does no pulls at all.

EPG & retention

EPG history (days) How many days of real provider EPG are kept in the database. Placeholder grid (hours) Length of the generated “Unknown Programming” grid for channels the provider has no EPG for. 0 disables the grid. EPG window hint (hours) The nominal EPG window passed to the provider; the service itself does not depend on it.

PORT, BIND, DATA_DIR, PUID and PGID stay environment variables — the port must be known before the server can bind, and the file itself lives inside DATA_DIR.
