FAQs
What is a live streaming SDK?
A live streaming SDK is a software development kit that provides the tools and resources needed to add live video streaming features into an application. It usually includes pre-built libraries, APIs, documentation, and sample code to simplify development. By using a live streaming SDK, developers can integrate video capture, encoding, transmission, and playback into their apps quickly, while ensuring performance and scalability without having to build everything from scratch.
What is a live streaming API?
A live streaming API is an interface that allows applications to communicate with a streaming platform using defined rules and commands. It lets developers start and stop streams, manage viewers, adjust settings, and access analytics programmatically. By using APIs, you can integrate streaming capabilities into your app without handling low-level video processes, making it easier to connect your application with existing streaming services.
When should I use a live streaming SDK?
You should use a live streaming SDK when you want to integrate streaming features directly into your application without building complex infrastructure on your own. SDKs are most useful when you need faster development, reliable performance, and built-in tools like adaptive bitrate streaming, chat integration, or interactive features. They simplify coding tasks and provide ready-made functionality, allowing you to deliver high-quality streaming experiences to your users more quickly.
What platforms do Red5 SDKs support?
iOS, Android, Windows, macOS, Linux, Unity, Unreal, HTML5. This wide coverage ensures that whether you are targeting mobile, desktop, web, or game engines, you can deliver consistent, real-time streaming experiences without additional compatibility concerns.
What latency should I expect?
With Red5 SDKs, you can achieve sub-250 millisecond latency using WebRTC and the Red5 XDN for real-time delivery. In cases where ultra-low latency is not required or network conditions demand it, the system can fall back to HLS for broader device compatibility. This flexibility allows you to balance speed, reliability, and reach depending on the needs of your application.
Can I monetize my streams?
Yes, Red5 SDKs make it simple to build monetization workflows into your streaming applications. You can enable live-to-VOD recording for on-demand playback and integrate our patented technology of server-side ad insertion (SSAI) for seamless, scalable ad delivery. These features allow you to create new revenue streams while maintaining a smooth viewer experience, whether you are targeting subscriptions, advertising, or hybrid models.
How long does it take to integrate live streaming features into my existing app using SDKs?
The time required to integrate live streaming features with SDKs depends on your app’s complexity and the features you want to add. Many developers can implement basic streaming within a few hours using sample code and documentation included in the SDK. For advanced features such as real-time interactions, analytics, or large-scale deployments, integration may take several days, but SDKs significantly reduce development time compared to building from scratch.
How much does it cost to use Red5 SDKs?
Pricing starts at $419 per launched project. You can try the SDKs with a 30-day Red5 Pro trial or via Red5 Cloud’s Pay-As-You-Grow free tier (50 GB and 6,000 instance hours monthly). Contact us to discuss your project.
