Video description and media credits

Mimir on NVIDIA SHIELD: browse an M3U/XMLTV programme guide, watch a stream and schedule a recording with adjustable padding. In a separate controlled test, the demo source was interrupted for 35 seconds. Mimir retried, resumed capturing and assembled the received footage into one saved recording. Playback shows a clock jump across the missing interval, including retry time. Footage that never arrived cannot be recreated. The test was stopped early after recovery; the playback excerpt across the join is uncut.

The Apple TV video shows the guide, live viewing and recording options in the Apple TV app, followed by playback of the same saved recovery test. Its playback excerpt across the interruption is also uncut, at normal speed.

The server is free. Native apps have a free trial and require a subscription after the trial.

Watch together

One tuner stream.
As many screens as you like.

Most recording software opens a fresh connection for every viewer, so the second person to tune in gets an error. Mimir doesn't work that way.

  • Shared live streams The server pulls a channel once and fans it out to everyone watching it. Five TVs on the same match cost exactly one tuner stream.
  • Watch what's recording A recording in progress is just another subscriber to that same stream, so you can sit down and watch the programme being captured without disturbing it.
  • Recordings always win When capacity is tight, a scheduled recording takes priority over casual viewing, and anyone bumped is told exactly why, not left staring at a spinner.
  • The right format per device Televisions get a direct transport stream for the lowest possible latency; phones and tablets get adaptive HLS. Same channel, same server, no configuration.
How Mimir shares one tuner stream across many screens A network TV tuner feeds a single stream into the Mimir server, which fans that one stream out to a television, a second television, a laptop and a phone at the same time.

The server

Everything a home TV system should do

A complete recording and streaming server in a single install: guide, scheduler, channel manager and player, with nothing to wire together.

Live channel streaming

Tune to any channel from a browser or a TV app and it starts in seconds. Televisions get a direct transport stream; mobile devices get adaptive HLS automatically.

Scheduled recording

Record anything in the guide with one click, with adjustable padding either side so an overrunning match never costs you the ending.

Full programme guide

A searchable guide grid with now-and-next, programme detail and recording badges, built from the XMLTV data your tuner or provider publishes.

Real channel management

Browse every channel your source offers, pick the ones you actually want, drag them into the order you want, and rename, renumber, regroup or re-logo any of them, all without touching the source.

Several sources at once

Combine more than one channel playlist and guide feed, and set which one wins when listings overlap. Base data refreshes on its own schedule; your customisations sit on top and survive every refresh.

Per-device security

Every TV pairs with its own hardware-backed key, approved once on screen. No password is ever typed on a remote, and any single device can be revoked without disturbing the others.

In the house and out of it

Your TV doesn't stop at the front door

At home, apps find the server by themselves: no addresses to type, no settings to keep in sync when your router hands out a new lease. Away from home, the same guide, the same channels and the same recordings are a browser tab away.

  • Zero-configuration discovery The server announces itself on your network and the apps simply find it. If its address changes, they follow it.
  • Remote access that isn't a hack Put Mimir behind a reverse proxy such as Caddy or Nginx and you get a proper certificate and a proper hostname, with no port-forwarding folklore and no third-party relay in the middle.
  • Start watching before it's finished Recordings are playable and seekable while they are still being captured. Start the film twenty minutes in and skip straight to where you want to be.
  • Nothing leaves your house No cloud account, no telemetry, no upload. Recordings are ordinary files in a folder you chose, on a disk you own.
Access at home and away from home Inside the home, devices reach the Mimir server directly over the local network. Outside the home, devices reach the same server through an encrypted connection over the internet. HOME NETWORK Mimir + RECORDINGS Apple TV Android TV Anywhere TLS
Bring your own tuner

Mimir doesn't replace your tuner.
It makes it worth having.

A network TV tuner turns an aerial, cable or satellite feed into channels your network can see. That's the hard part solved. But on its own a tuner gives you a list of streams, not a television experience. Mimir is the half that's missing: the guide, the scheduler, the recordings and the apps.

Network tuner

SiliconDust HDHomeRun

The best-known networked TV tuner family. An HDHomeRun puts your off-air or cable channels onto the LAN and publishes them as a standard channel playlist. Point Mimir at that playlist and every channel the tuner can see becomes searchable, recordable and playable on every screen you own, and multi-tuner models let several different channels run at once.

TV gateway

VBox TV Gateway

VBox gateways cover terrestrial, satellite and cable in one box and publish both a channel playlist and a full XMLTV programme guide. That pairing is exactly what Mimir wants: the playlist supplies the channels, the guide fills the grid, and scheduling a recording becomes a single click on a programme.

No tuner? An M3U playlist is all you need

Hardware is one way in, not the only way. Any source publishing an M3U channel playlist and an XMLTV programme guide works just as well, whether that's a tuner, a gateway, or files already sitting on the machine. Run several at once with a priority order deciding which listings win, override any channel's name, number, group, logo or guide mapping, and keep every one of those changes through every refresh.

How M3U and XMLTV support works
Getting going

Running in about ten minutes

Install the server

Run the signed Windows installer, the macOS build, or bring up the Docker container. It starts a setup wizard in your browser, so there's no config file to write and no token to copy out of a terminal.

Add your channel source

Paste the playlist and guide addresses your tuner or provider gives you. Mimir indexes the channels, then you pick the ones you want and put them in the order you want them.

Watch and record

Open the guide, click a programme to record it, or click a channel to watch it, in the browser or in the native TV apps.

Docker · one command 
# pull, build and start Mimir in the background
docker compose up --build -d

# then open http://localhost:8094/

Questions

Before you download

Is the Mimir server really free?
Yes. The server and its built-in web interface are free to download and use, with no account, no subscription and no usage limits. The native TV and mobile apps are free to download and need a subscription to use, with a free trial to start, and that's what funds the work.
What hardware do I need to run it?
Any always-on computer on your network: a Windows PC, a Mac, a Linux box, or a NAS that runs Docker. You'll also need a channel source: a network TV tuner such as a SiliconDust HDHomeRun or a VBox TV Gateway, or anything else that publishes an M3U channel playlist and an XMLTV programme guide.
Does it work with an M3U playlist and XMLTV guide?
Yes. It's the most common way people set Mimir up. Add your M3U playlist and XMLTV guide as a source and you get a searchable programme grid, one-click recording, and a channel lineup in your own order with your own numbering. Several playlists and guides can run at once. Full detail here.
Can several people watch different channels at the same time?
Yes. How many different channels can run at once depends on how many tuners your hardware has, which is a limit of the tuner, not of Mimir. What Mimir adds is that everyone watching the same channel shares a single stream, so any number of screens can watch one programme together at no extra cost, and you can configure how many concurrent streams each source is allowed.
Can I watch when I'm away from home?
Yes. Mimir runs behind a reverse proxy such as Caddy or Nginx with a real TLS certificate, so live channels, the guide and your recordings are all available over the internet through the same interface you use at home.
Where do my recordings live?
In a folder you pick, on your own machine, as ordinary video files. There is no cloud component: nothing is uploaded, nothing is analysed, and no external account is involved at any point.
Do I need the apps to use the server?
No. The server ships with a complete web interface covering guide, channel management, recording, scheduling and playback, and it works in any modern browser on a desktop, tablet or phone. The apps are for people who want a native experience on the television itself.
Which devices will the apps support?
Apple TV, Android TV and NVIDIA SHIELD, and Android phones and tablets are out now; the iPhone and iPad app is with Apple for review. Details and store links here.

Take your television back.

Download the server, point it at your tuner, and have a proper guide and a proper recorder running before the evening's viewing starts.
