- src/buffer_state.go replaces the two sync.Maps plus a global RWMutex with one bufferMu guarding a map of *Playlist. Each stream has one shared bufferStream (URL, folder, status, client count, error, cancel hook); downloaders keep a private ThisStream and publish through helpers. Playlist.Clients / ThisClient / ClientConnection are gone: there was one client counter per stream in two places that could disagree. - bufferAcquireStream does the tuner check and the registration under the same lock, so two clients tuning at once cannot both pass the limit. bufferReleaseClient removes the stream when the last client leaves, cancels its process and deletes its segment folder. - bufferingStream rewritten: waits on r.Context() instead of the deprecated CloseNotifier, sets Content-Type before WriteHeader (the old code set headers after and one was literally named "Content-Length:"), flushes each segment to the client, no defer inside the segment loop. - connectToStreamingServer: shared streamHTTPClient with dial, TLS and response-header timeouts (no overall timeout, bodies are endless); the deferred Body/segment closes inside the redirect and read loops are now explicit closes, so a multi-hour stream no longer accumulates them. - thirdPartyBuffer rewritten around exec.CommandContext: the process is killed when the last client leaves or when no usable data arrives within 20 s (time.AfterFunc watchdog, no leaked goroutine); cmd.Start error is checked; no panic; one file handle per segment. ffmpeg and VLC command lines come from buildFFmpegArgs / buildVLCArgs, which are unit tested. - Data.Cache.StreamingURLS is guarded by streamingURLsMu and persisted from a snapshot. - Tests (src/buffer_test.go, run with -race): restream shares one provider connection, six concurrent tunes against a tuner limit of two, 50-way acquire/release contention, cleanup and cancel on last release.
xTeVe
M3U Proxy for Plex DVR and Emby Live TV.
Documentation for setup and configuration is here.
About this fork
The upstream xTeVe project has been inactive since 2021. This fork is maintained privately for a single trusted LAN. It is Docker-only and built for amd64 only. There are no release archives and no self-update.
What it adds over upstream:
- Web UI redesign with a mobile and accessibility pass (responsive navigation, keyboard flow, focus visibility, ARIA announcements, contrast).
- Plex API guide refresh: after a lineup or XEPG update xTeVe can ask Plex to reload the DVR guide. New settings:
use_plexAPI,plex.url,plex.token. - Strict or relaxed handling of channels whose EPG source went missing in XEPG, with automatic re-mapping.
- A wizard-completed flag so the setup wizard is not shown again on restart.
- First-party Docker image with a static ffmpeg, runtime
PUID/PGID, and a healthcheck. - Drone CI: vet, tests, web bundle check, Dockerfile lint, compose validation, image publishing.
- Web UI embedded in the binary with
go:embed. - Unauthenticated
GET /healthzendpoint for container health checks. - The self-updater and the GitHub branch switching are removed.
The plan for further work is in tasks/improvement-plan.md.

Running the container
Image
The image is built by Drone and pushed to a private registry:
registry.coadcorp.com/nathan/xteve
Tags:
latestand<commit sha>from themasterbranch.<branch name>and<commit sha>from every other branch.
docker pull registry.coadcorp.com/nathan/xteve:latest
The image is linux/amd64 only.
Start with Docker Compose
Bridge mode (default). The web UI is on port 34400.
docker compose up -d
Host networking. Use this if you want Plex or Emby to discover the tuner by SSDP/DLNA. Multicast does not cross the Docker bridge, so publishing UDP 1900 in bridge mode is not enough on its own. Linux only.
docker compose -f docker-compose.host.yml up -d
In bridge mode you can still add the tuner manually in Plex or Emby with http://<host-ip>:34400.
Both compose files pull registry.coadcorp.com/nathan/xteve:latest. To build locally instead, uncomment the build: block in the compose file, or run docker build -t xteve:local ..
Environment variables
| Variable | Default | Meaning |
|---|---|---|
XTEVE_CONFIG |
/xteve/config |
Config directory inside the container. |
XTEVE_PORT |
34400 |
HTTP port xTeVe listens on. |
PUID |
1000 |
User id xTeVe runs as. Set it to the owner of the host config directory. |
PGID |
1000 |
Group id xTeVe runs as. |
TZ |
unset (UTC) | Time zone, for example Australia/Sydney. |
The container starts as root, sets the xteve user to PUID/PGID, fixes the ownership of the config directory if needed, and then drops to that user before starting xTeVe. If the container is started with --user, the ids are left alone and xTeVe runs as the given user. The old XTEVE_UID/XTEVE_GID variables are still accepted as aliases.
Volume
The config lives in /xteve/config (declared as a volume in the image). The compose files bind it to ./docker-data/config. It holds settings.json, the mapping and EPG data, backups and the cache, so it is small enough to back up as a whole.
If an older container kept its config in /config or /home/xteve/.xteve, the entrypoint copies it to the new location on first start.
Healthcheck
The image has a HEALTHCHECK that requests http://127.0.0.1:${XTEVE_PORT}/healthz every 30 seconds. The endpoint needs no authentication and returns the version and whether a scan is in progress. docker ps shows the state as healthy or unhealthy.
ffmpeg
A static ffmpeg and ffprobe are in the image at /usr/local/bin/ffmpeg and /usr/local/bin/ffprobe, taken from the pinned mwader/static-ffmpeg image. In a container xTeVe defaults ffmpeg.path to that location. VLC is not included.
Security notes
- This fork is meant for a trusted LAN. Do not put it on the internet.
- Web authentication is off by default. Turn it on under Settings > Authentication before you expose it any further than the LAN, for example through a reverse proxy.
/healthzis always unauthenticated. It reveals the version and scan state only.- The container starts as root to apply
PUID/PGIDand then drops privileges. Start it with--userif you prefer it never to run as root.
Development
See README-DEV.md for the layout, how to build the binary and the web UI, and how CI publishes the image.
