Multi-stream broadcasting,
on your machine
Flumixa Media Server ingests RTMP from any encoder, mixes video and audio across cameras, records to disk, runs scheduled broadcasts, and streams to YouTube, Twitch and Kick at the same time. A desktop app for macOS, Windows and Linux — no cloud, no subscription.
A full broadcast pipeline in one app
Six capabilities that usually take three separate tools — running locally on your laptop or studio machine.
Multiple inputs
Take RTMP from OBS, hardware encoders or a phone. Loop local media files. Add as many sources as your machine can handle.
Video & audio mixer
Pair the picture from one source with the sound from another. A delay slider lines audio back up with the image. No external mixer needed.
One-click recording
Save any source or the finished mix to MP4, in a folder you choose. Full broadcast quality, no re-encoding.
Scheduler
Set up a one-off or weekly recording and broadcast. Configure it once and it starts on its own.
Many destinations at once
One stream goes to YouTube, Twitch, Kick, Restream and any other RTMP address simultaneously, from a single machine.
Preview over your network
Flip one switch and the app serves a low-latency HLS feed across your LAN. Scan the QR code to monitor the show from a phone or tablet.
On air in four steps
From a fresh install to broadcasting on YouTube in under five minutes.
Add a source
Open Sources and click Add source: give it a name and pick the type — RTMP ingest or a local file.
Point your encoder at it
Copy the publish URL into the OBS stream settings. The source shows up in about three seconds.
Add a destination
Destinations → Add destination: pick YouTube, Twitch or Kick and paste the stream key.
Press Go live
One button in the top bar, and the stream goes out to every destination at once.
An interface for operators, not for screenshots
Dense, technical, quick. Every value in plain sight, no chains of nested dialogs.
Sources and live preview
Every input on one screen: RTMP ingests, USB cameras, screen captures, media files. Click a source and its preview comes up right away.
- FPS, bitrate and dropped-frame counters for each source
- Swap audio and video on the fly, without restarting the stream
- Drag to reorder, right-click for advanced settings
Broadcasting to several destinations
Add YouTube, Twitch, Kick, Restream or any custom RTMP address. Each one has its own connection status, bitrate and time on air — and the stream goes to all of them at once.
- Separate connection status per destination
- Automatic reconnects with increasing back-off
- Stream key checked before you go live
Recordings and schedule
Record any source or the mix to disk with one button. Jobs can be one-off or weekly, and you choose the output folder.
- Plain MP4 — no re-encoding
- Broadcast quality kept intact
- If the app crashes, the unfinished file still plays
Free during beta. And honest about what already works.
The core pipeline — ingest, mix, record, schedule, broadcast — works end to end. It also has rough edges, the occasional crash and breaking changes between versions. If something goes wrong, attach the log and open an issue: we reply within a few days.
Runs on what you already have
The installer is small and memory use is modest: around 512 MB when idle and about 1 GB while on air.
