Agora Live Interactive Video Streaming enables one-to-many and many-to-many audio or video live streaming with the Agora RTC SDK.
Agora Live Interactive Video Streaming is different from Agora Video Call. In a video call, all users are the same role and can talk to each other freely. In a live video streaming, users can be the host or audience, where only the host can talk. For details, see this FAQ.
Different from the traditional CDN live broadcast, which only allows one-way communication from the hosts to the audience, the Agora RTC SDK empowers the audience to interact with the hosts by becoming a host, like a viewer jumping onto the stage in the middle of a play to perform.
The Agora RTC SDK is applicable to scenarios that encourage active engagement, such as game-playing, online classes for students in small groups, and Q&A sessions during E-commerce live streaming. You can also use this SDK for one-to-one video calls that require high image quality.
