Live encoding is one of the less forgiving parts of broadcast infrastructure. Unlike file transcoding, there's no second chance. When a live channel goes down, everyone knows about it immediately - operators, engineers, and viewers. The signal chain has to work, reliably, every time.
For many broadcasters and content owners running fixed, permanent channel lineups, the answer to that reliability question is on-premise encoding. Keeping the encoder close to the source, inside the facility where the signal arrives, removes a network dependency that simply doesn't need to be there. It keeps the critical path short and the signal chain under direct control.
Cambria Stream Solo is built for exactly that requirement.
What it is
Stream Solo is on-premise software-based live encoding, running on Linux on a wide range of standard hardware platforms. Running on Linux removes a layer of operational complexity for engineering teams who've spent time managing Windows-based encoding infrastructure - cleaner deployment, fewer moving parts, and it sits naturally inside existing Linux broadcast environments.
It's built on the same core encoding engine that powers the broader Cambria family - FTC, Packager, Live, and Stream. That matters because it means consistent encoding quality and consistent behavior across every part of the Cambria infrastructure a facility might run. The operational model doesn't change depending on which Cambria product you're working with.
Stream Solo accepts all the inputs you'd expect in a professional broadcast environment: SDI, SRT, UDP, RTMP, Zixi, NDI, HLS-TS, and Media File. Output formats include CMAF, CMAF CTE, HLS, SRT, RTP, MP4/TS, RTMP/RTMPS, and Zixi, with full SCTE-35 support for dynamic ad insertion.
Stream Solo supports both direct live encoding and contribution workflows. It can create the required output profiles for downstream delivery, or provide a high-quality encoded feed into distribution, packaging, or cloud-based processing systems. Both use cases are handled within the same product, without requiring a separate encoder platform
Who it's for
Stream Solo suits broadcasters and content owners running fixed channel lineups from established facilities. If you have contribution feeds arriving on-site - SDI, SRT, or IP - and you want to keep the encoding inside the building where the signal chain is under your
control, Stream Solo fits that requirement directly.
It's available in three configurations: Stream Solo (one channel), Stream Duo (two channels), and Stream Quad (four channels). The capacity matches the requirement rather than over-engineering for flexibility you don't need.
For production companies and event operators running live streaming at a consistent scale, it offers the quality and reliability of the Cambria encoding engine without the commitment to a larger live platform than the job justifies. Deploying on standard server hardware keeps the total cost of ownership straightforward.
Fixed channels and facility economics
Cloud live encoding has clear advantages for event-based production, pop-up channels, and workloads where demand is genuinely unpredictable. For those use cases, the ability to scale on demand without committing to permanent infrastructure makes economic sense.
For fixed, permanent channels running continuously, the calculus is different. A channel that runs 24/7 isn't an unpredictable workload - it's a steady, known cost. On-premise encoding keeps that cost predictable, avoids ongoing compute spend for capacity that never changes, and keeps the signal chain entirely within the facility.
Stream Solo is a straightforward fit for that model. Sized correctly, deployed on solid hardware, it handles permanent channel capacity cleanly without monthly recurring cloud costs for workloads that don't benefit from cloud flexibility.
The path forward
Stream Solo is designed to grow with the operation. For facilities that later need clustering across multiple encoding nodes, or want to add cloud and hybrid live encoding capacity alongside on-premise channels, Cambria Stream Solo can be upgraded to Cambria Stream Pro. Stream Pro adds full cluster management and cloud deployment across multiple environments, while running the same core encoding engine - so the quality, the operational model, and the team's existing knowledge all carry forward.
For facilities thinking about long-term infrastructure, that upgrade path means Stream Solo isn't a dead end. It's the right starting point for on-premise live encoding, with a clear route to a broader live encoding platform when the requirement grows.
