You can run MediaMTX as a systemd service on Ubuntu and forward a stream to YouTube over RTMPS. The setup needs an always-on Ubuntu host, a video-and-audio source publishing to MediaMTX, and the current ingest URL and stream key from YouTube Studio. Starting at boot helps the relay recover after a host restart; it does not guarantee uninterrupted delivery from your source, internet connection, host, or YouTube.
How the setup works
MediaMTX is the relay on your Ubuntu host: a source publishes a stream to it, and MediaMTX forwards that stream to YouTube. MediaMTX describes itself as a media router and supports publishing and forwarding streams. MediaMTX introduction
This is not a way to turn a video file into a live stream by itself. You need a source that publishes a live audio-and-video stream to a MediaMTX path. MediaMTX’s FFmpeg guide documents publishing an input file in real time, including looping an input, when that is the source you intend to use. Publish with FFmpeg
What you need first
- An Ubuntu host with systemd, configured to stay powered on and connected while you want the channel live.
- The MediaMTX executable and a configuration file, installed for the version you intend to run.
- A working source that can publish video and audio to MediaMTX.
- Network access between the source and host, and outbound access from the host to YouTube’s ingest service.
- Access to the channel’s current live-stream settings in YouTube Studio. Confirm that live streaming is enabled for the account and check any applicable current YouTube requirements there and in YouTube Help.
The available MediaMTX documentation does not establish India-specific account or encoder requirements, or whether a particular channel is eligible. Do not rely on an old endpoint example: use the destination URL YouTube Studio currently displays for your stream.

Install MediaMTX and configure systemd
MediaMTX’s Linux boot guide uses a global-path pattern: place the executable under /usr/local/bin/ and the YAML configuration under /usr/local/etc/, then define a systemd unit. Check the guide and the official release information for the current download and configuration before installing; the exact download commands can change between releases. MediaMTX: Start on boot (Linux)
Use a systemd unit
Adapt the following unit to match the paths and user permissions on your host. It follows the command pattern in the MediaMTX boot guide:
[Unit]
Description=MediaMTX
After=network.target
[Service]
ExecStart=/usr/local/bin/mediamtx /usr/local/etc/mediamtx.yml
Restart=on-failure
[Install]
WantedBy=multi-user.targetThe guide’s sample unit uses the same ExecStart path pattern and WantedBy=multi-user.target. It recommends enabling systemd-networkd-wait-online.service so startup can wait for network initialization. Whether that service is relevant depends on how networking is configured on your Ubuntu installation. Check the guide and your host’s network manager rather than enabling an unrelated wait service by habit.

Reload, enable, and start
- Save the unit as
/etc/systemd/system/mediamtx.service, adjusting paths if your installation differs. - Run
sudo systemctl daemon-reloadso systemd reads the new or changed unit. - Run
sudo systemctl enable mediamtxto configure systemd to start it at boot. - Run
sudo systemctl start mediamtxto start it now. - Check
sudo systemctl status mediamtxandsudo journalctl -u mediamtxfor the service state and startup errors.
The boot guide documents enabling and starting the service; checking status and journal output is an operational verification step. MediaMTX: Start on boot (Linux)
Configure the source path and YouTube forwarding
Configure a MediaMTX path for the source to publish to, then configure forwarding from that path to YouTube. The forwarding destination uses RTMPS and your channel’s stream key. Follow MediaMTX’s current forwarding instructions, but copy the ingest URL shown in your YouTube Studio stream settings instead of assuming a documentation example is still current. MediaMTX: Forward streams (YouTube)
- In YouTube Studio, open the live-stream setup for the channel and copy the current server or ingest URL and stream key.
- In the MediaMTX configuration, set up the publishing path and the forwarding destination according to the current MediaMTX guide. Use the exact current YouTube URL and key for the intended stream.
- Keep the stream key private. Treat it like a password: do not put it in public configuration repositories, screenshots, or exposed logs. If it is disclosed, replace or reset it using the controls available in YouTube Studio.
- Start the source and confirm that MediaMTX receives it and forwards it. Check MediaMTX logs and the live preview or status in YouTube Studio before relying on the setup.
MediaMTX explicitly warns that YouTube requires both an audio track and a video track; a video-only stream can be silently rejected. MediaMTX: Forward streams (YouTube)

MediaMTX’s introduction says it can serve always-available streams when a publisher is offline, but that does not mean a missing source will provide new program content or that YouTube will remain connected. MediaMTX introduction
What “24/7” depends on
Enabling a systemd service helps MediaMTX start when Ubuntu boots. MediaMTX also documents service and stream capabilities such as authentication, recording, metrics, and performance monitoring.

- Host and power: A shutdown, crash, maintenance reboot, or power loss stops the relay until the host is available again.
- Network: A local or upstream connection failure can interrupt publishing or forwarding. Evaluate host bandwidth, outbound-transfer terms, and the route to the YouTube ingest URL you select.
- Source: If the publisher stops, the relay cannot forward fresh content from it. Decide how the source will restart and how you will notice that it has stopped.
- Destination: YouTube can disconnect or reject a stream. Monitor the YouTube status and MediaMTX logs, and plan how you will respond to an interruption.
If you host the relay on a VPS or dedicated server, compare its bandwidth and transfer limits, restart controls, monitoring options, route to the selected ingest endpoint, and the maintenance you can perform on Ubuntu. A hosting provider can supply a place to run the service; it does not by itself ensure an uninterrupted YouTube stream.

The systemd service will not start
Check sudo systemctl status mediamtx and sudo journalctl -u mediamtx. Confirm that the executable and configuration file exist at the paths used in ExecStart, that the service can read them, and that the configuration is valid for the installed MediaMTX version.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsMediaMTX starts, but YouTube does not accept the stream
Verify the current RTMPS ingest URL and stream key in YouTube Studio, then check the forwarding configuration and MediaMTX logs. Confirm that the incoming stream contains both audio and video; MediaMTX warns that YouTube requires both and may silently reject video-only input. MediaMTX: Forward streams (YouTube)

The stream works until a reboot
Check that you ran sudo systemctl enable mediamtx, then inspect the service state and journal after reboot. If MediaMTX starts before the network is ready, review the boot guide’s network-wait recommendation and adapt it to the network manager actually used by the Ubuntu host. MediaMTX: Start on boot (Linux)
The service is active but the channel has no new content
Check whether the source is still publishing to the configured MediaMTX path and whether the relay is receiving the expected audio and video. A running service alone does not prove that the source or YouTube connection is healthy; compare MediaMTX logs with YouTube Studio’s stream status.
Or let it run in the cloud
If your goal is an always-on YouTube channel built from uploaded videos rather than a live camera feed, StreamNeo is an alternative to maintaining an Ubuntu host and relay.
