MediaMTX itself is free: the code in its main repository is released under the MIT License. But running a continuous YouTube stream is not necessarily cost-free. You still need an always-on host and a reliable network connection, and you may have hosting or connectivity costs.
What “free” means for MediaMTX
MediaMTX is a media server and proxy that can publish, read, proxy, record, and play streams, convert between protocols, and forward streams. The project states that all code in its main repository is released under the MIT License. That means there is no MediaMTX software license purchase price; it does not mean that the machine and network needed to run it are free. Read the license details.
Compiled binaries also include third-party dependencies, whose licenses are listed on the project’s license page. The MIT statement applies to the main repository code, not automatically to every bundled component.
What you need to keep a YouTube stream running
- A host: a computer or rented server that can remain powered and connected. MediaMTX documents installation as a standalone binary or with Docker; Docker is recommended in its guide for production environments, but it is not required for every setup. See the installation guide.
- Network capacity: the host needs a working connection to YouTube. For forwarding without re-encoding, MediaMTX says bandwidth between the server and readers is commonly the bottleneck. The cited guidance does not specify a universal minimum bandwidth, so capacity depends on the stream and its audience. See MediaMTX’s scaling guidance.
- Audio and video: the source stream must include both tracks. MediaMTX’s YouTube guide says YouTube requires a video and an audio track, and that video-only streams are silently rejected. See the YouTube forwarding guide.
If you already have suitable equipment and connectivity, your additional hosting cost may be zero. If not, renting an always-on host is one option; the sources do not establish a particular provider or price.

#1 Best Overall
ZowieBox, 4K HDMI NDI Video Encoder/Decoder, HDMI NDI
- Compact but Powerful Design: ZowieBox is smaller than a phone, featuring a tally light and LCD screen for streaming status. Capture console gameplay in up to 4K with zero-lag HDMI passthrough, while the built-in video encoder converts video for IP streaming. The IP stream can also be decoded back to a 4K HDMI signal.
- Standalone Game Streaming: Just plug and play—ZowieBox enables PC-free live gaming without affecting gameplay. As an RTMP hardware encoder and HDMI streamer, it delivers stable streaming directly from your source, making it ideal for gaming, live events, and professional broadcasting.
- NDI|HX3 Converter Technology: ZowieBox converts HDMI signals to NDI|HX3/HX2/HX, functioning as an NDI video encoder, or NDI Video Decoder for flexible IP workflows. Certified NDI technology enables low-latency gameplay streaming through OBS/vMix. Note: Encoder and decoder modes cannot run simultaneously; full NDI signals are not supported.
- UVC to HDMI Conversion: Supporting up to 4K@30fps and 1080p@60fps decoding, ZowieBox enables flexible conversion for webcam and video workflows. As a video decoder and HDMI to IP converter, it expands connectivity options for professional video devices. Note: USB capture card functionality is not currently supported.
- All-around Configuration Options: Control ZowieBox through its web UI on a PC, phone, or tablet. Manage connected PTZ cameras, tally light, video/audio, OSD, work mode, streams, network, and system settings. Support for VISCA over IP encoder workflows enables flexible PTZ control, while the dashboard provides video preview and system status.
How MediaMTX forwards a stream to YouTube
- Prepare the source. Make sure the incoming stream contains both audio and video tracks.
- Install MediaMTX. Choose the documented standalone binary or Docker deployment based on how you plan to operate the host. Docker is the guide’s recommendation for production environments, not a universal prerequisite. Follow the official installation instructions.
- Get the current YouTube ingest details. In YouTube Studio, obtain the stream URL and key for your broadcast. The MediaMTX guide’s example ingest address may be out of date; it specifically says to check YouTube Studio for the current URL.
- Configure forwarding. In MediaMTX’s publishing configuration, set the destination using the YouTube URL and stream key. The guide recommends using
rtmps://rather thanrtmp://to encrypt the transport. Do not copy an old example URL without checking the current value in YouTube Studio. - Start the source and verify the result. Confirm that MediaMTX receives the stream and that YouTube receives both audio and video. Monitor the host and its network connection if you intend to leave the stream running.
See the MediaMTX guide to publishing to YouTube for its configuration example. The available documentation establishes the forwarding setup, but it does not establish YouTube account eligibility, current duration limits, or an uptime guarantee for an uninterrupted 24/7 broadcast.
Choosing between a local machine and a rented host
Neither approach is inherently right for every channel. Compare the practical requirements before choosing:

| Question | Use equipment you already have | Rent an always-on host |
|---|---|---|
| Can it run continuously? | Use it only if it can stay powered and connected for the intended schedule. | Check that the selected host can remain available for your intended schedule. |
| What does it cost? | Potentially no added hosting charge if the machine and connection are already suitable; power and connectivity still matter. | Hosting is an additional cost. A specific provider or price is not established here. |
| What should you check for stream delivery? | Check your connection’s capacity for the stream and audience. | Check the host’s network capacity for the stream and audience. |
| How do you deploy MediaMTX? | The documented standalone binary or Docker can be used; choose what you can operate reliably. | The same documented deployment choices apply; Docker is recommended by the guide for production environments. |
Or let it run in the cloud
If you want a YouTube channel to keep playing uploaded videos without maintaining a MediaMTX host yourself, StreamNeo is a separate cloud option: upload a recording or build a playlist, add your YouTube stream key, and go live. It keeps the stream running from the cloud, so no computer or home connection has to stay on. Any uploaded quality up to 4K 60fps streams at one flat price per slot, and StreamNeo automatically recovers if YouTube drops the stream. The first day is free with no card. Monthly pricing is $9.99 per month. StreamNeo is for uploaded videos streamed to YouTube, not camera broadcasts. Learn more at StreamNeo, or start the free first day.
