An stream enables you to deliver your content to your audience.

At the time of creation, Ceeblue creates the optimal architecture to support your stream based on your requirements:

Input and output locations
Codecs supported by the output device
Video and audio formats

Therefore, you should create a new stream immediately before using it.

Ceeblue will automatically scale up resources and load balance during the live stream to ensure a quality user experience.
