| Live Co-hosting | Multiple hosts can appear in one room for on-screen co-hosting live streaming. |
|
| Supplemental Enhancement Information (SEI) | Text information is packaged with audio and video content and transmitted through the streaming media channel to achieve precise synchronization between text data and audio and video content. |
|
| Traffic Control | ZEGO industry-leading technology. The SDK dynamically adjusts the video stream's bitrate, frame rate, and resolution, as well as the audio bitrate, based on its own and the remote endpoint's current network environment status, automatically adapting to the current network environment and fluctuations, thereby ensuring smooth video publishing. | All scenarios that require high-quality real-time audio and video services |
| Audio/Video Stream Encryption | Encrypt the stream when publishing, and must have a decryption key consistent with the encryption key when playing. | Scenarios that need to encrypt stream information to protect communication security |

| H.265 | Through the more advanced H.265 encoding technology, provides higher clarity at the same bitrate. | Higher audio/video call and live streaming experience under poor network environments, more sensitive to bandwidth |
Live Streaming Capabilities
Basic Features
| Basic Features - 20% | Feature Description - 50% | Business Scenarios - 30% |
|---|---|---|
| Use CDN for Live Streaming | Unified access to multiple CDN capabilities. This feature supports publishing streams to CDN, connecting RTC products and CDN live streaming products, making it convenient for users to watch live content directly from web pages or third-party players. | Basic live streaming with high concurrency, scenarios without strong requirements for live streaming delay |
| Play Stream by URL | When the publishing end uses third-party publishing tools (such as OBS software, network cameras IP Cameras, etc.) to push streams to CDN, or uses ZEGO SDK's CDN relaying feature to push audio and video content to third-party CDNs, you can use the method of directly passing in the URL address to play streams. | Third-party live screen capture |
