CeraLive is pre-release. What works today

One stream.
Every connection you have.

CeraLive is a live-streaming system designed for you to build yourself.

Most of its software is open source. It combines multiple connections to send one stream.

HDMI video capture and encoding up to 4K at 59.94 fps, with H.264 or H.265.

Capabilities depend on the hardware and input format.

Why we built CeraLive

For years, broadcasters have gone live from anywhere with bonded-cellular systems: professional equipment that combines several mobile connections into one reliable feed. It works very well, and it is designed and priced for networks and large productions.

Independent creators, event crews and community and regional broadcasters have had few open, high-quality options they could build, own and repair themselves.

CeraLive is that option. Software built on open source turns a small single-board computer with hardware video encoding into a bonded live encoder. It sends one stream over cellular, Wi-Fi and Ethernet at the same time, so your broadcast stays on air when a connection drops. You choose the parts, you own the device, and you decide where the stream goes.

Quality you can check

  • 4K at 59.94 fps over HDMI on both boards, in H.264 and H.265. Capture and encoding are 8-bit; this does not cover every camera or input format, exact 60 fps, or HDMI audio at 4K.

    Cameras and captureRecorded HDMI results

  • Cellular, Wi-Fi and Ethernet bonded at once, so losing one link doesn’t stop the stream.

    Bonding explained

  • Works with standard SRTLA receivers, BELABOX-compatible or your own, and with OBS over SRT.

    Choose where your stream goes

  • Both boards have streamed for more than 12 hours straight: HDMI capture, H.264 and H.265 encoded on the board, sent over bonded connections.

Who it’s for: IRL streamers, event and sports producers, and community, regional and news broadcasters.

How it flows

The camera feeds the CeraLive device. It splits one stream across every link you have, a receiver puts the packets back together, and OBS sends the result wherever you stream.

Three links. One stream.

srtla_send sends every packet over the link best placed to carry it, using each link's capacity, recent losses and round-trip time: scheduled, not striped or mirrored.

Cut a link yourself

Throttle or cut any link and watch its share move to the others. Cut two, and the last link keeps the stream on air only if it can carry it alone.

Simulation — runs in your browser, not on a device

This simulation needs JavaScript. Turn it on to throttle and cut the links.

When a link fails

IllustrationHow a link failure plays out: a link that fails or stalls stops carrying the stream, and the sender moves its share to the remaining links; a link that goes silent is dropped after 15 seconds. The stream stays on air as long as the remaining links can carry it.

Replaying the failure needs JavaScript.

What is CeraLive?

CeraLive is a live-streaming system designed for you to build yourself. Most of its software is open source. The device compresses your camera’s video and sends one stream across multiple connections at once. A receiver puts the packets back together into one stream for your viewers. Results from tested setups: 4K at 59.94 fps over HDMI on both boards, in H.264 and H.265. Result confirmed by the CeraLive team (no logs attached). Capture and encoding are 8-bit; this does not cover every camera or input format, exact 60 fps, or HDMI audio at 4K.

How long can CeraLive stream?

Both boards have streamed for more than 12 hours straight: HDMI capture, H.264 and H.265 encoded on the board, sent over bonded connections. Result confirmed by the CeraLive team (no logs attached).

Not yet. Images are coming soon; follow Discord for release news.

Do I need an account?

No. CeraUI, the control panel on your device, works without one: you set up and go live from your browser on the same network.

Read more:CloudCeraUI

Can I buy a CeraLive device?

No. It’s a do-it-yourself project: you build your device from a supported board and off-the-shelf parts, then flash the CeraLive image onto it.

Read more:What you needInstall

Is CeraLive open source?

Most of it is. The control panel, bonding sender, receivers, SRT library, modem and camera stacks are public; the streaming engine isn’t public yet.

Read more:Build it yourself

How many connections do I need?

To bond connections and keep streaming if one fails, you need at least two. You can stream over one connection, but there is no other link to take over. More links on different networks protect you better.

Read more:Bonding explained

Where can my stream go?

To a receiver: one you run yourself, a BELABOX-compatible receiver, or CeraLive Cloud when it launches. From there it goes on to OBS or your platform.

Read more:DestinationsCloud

Does it work with BELABOX receivers?

Yes. Sending to a BELABOX-compatible SRTLA receiver is Available.

Is CeraLive Cloud available?

Not yet. It’s coming soon.

What does it cost?
