|---|---|---|
| Live Co-hosting | In a room, multiple hosts can appear and conduct on-screen co-hosting live streaming. |
|
| Publish Multiple Streams Simultaneously | One user can publish multiple audio and video streams, such as sending the camera's video stream while sharing the screen. | Playing PPT while seeing the speaker's image in a video conference |
| Traffic Control | ZEGOCLOUD's industry-leading technology. The SDK dynamically adjusts the video publishing stream's bitrate, frame rate, resolution, and audio bitrate based on its own and the peer's current network environment status, automatically adapting to the current network environment and network fluctuations, thereby ensuring smooth video publishing. | All scenarios that require high-quality real-time audio and video services |
Room Capabilities
Basic Features
| Basic Features | Feature Description | Use Cases |
|---|---|---|
| Room Connection Status Description | Determine the user's connection status in the room and the conversion process of each connection status. | - |
| Real-time Messaging and Signaling | Real-time messaging mainly provides the function of sending and receiving plain text messages. You can send broadcast messages and barrage messages to other users in the same room, or send custom messages to specified users, and implement interactive functions such as likes, gifts, and quizzes as needed. |

Advanced Features
| Advanced Features | Feature Description | Use Cases |
|---|---|---|
| Multi-room Login | One user can enter multiple rooms at the same time for audio and video calls or watching live streaming. | Teachers teaching multiple classes online |
Audio Capabilities
Basic Features
| Basic Features | Feature Description | Use Cases |
|---|---|---|
| Audio Spectrum and Volume Change | Audio spectrum: the energy value of digital audio signals at various frequency points. Volume change: the volume level of a stream. |
|
| Headphone Monitor and Audio Channel Settings |
|
|
| Audio 3A Processing | During real-time audio and video calls or live streaming, 3A processing can be performed on audio to improve call or live streaming quality and user experience.
| All scenarios that require high-quality real-time audio and video services |
Video Capabilities
Basic Features
| Basic Features | Feature Description | Use Cases |
|---|---|---|
| Common Video Configuration | During video calls or live streaming, customize settings for capturing and playing video-related configurations, such as video capture resolution, video encoding output resolution, video frame rate, bitrate, view mode, and mirror mode, etc. |
|
| Video Capture Rotation | When users use mobile devices for live streaming or video calls, they can adopt different video capture directions, and can adapt and adjust according to the angle of the peer user's camera direction. | Video calls and live streaming scenarios with multiple device types, scenarios requiring the best video playback angle |
| Screen Sharing | Share screen content with other users in the room as video during video calls or interactive live streaming. |
|
| Basic Beauty Effects | When conducting video calls or live streaming, if you want to present a good skin condition to the other party, you can combine AI Effects to achieve basic beauty effects. |
|
Advanced Features
| Advanced Features | Feature Description | Use Cases |
|---|---|---|
| Set Video Encoding Method | Detailed settings can be made on video encoding and decoding, including enabling layered video encoding, using hardware encoding and decoding, and setting encoding methods, etc. | When there are special requirements for encoding and decoding |
| Custom Video Pre-processing | Developers perform custom pre-processing on video data by themselves. | Beauty effects, adding accessories, etc. |
| Object Segmentation | ZEGOCLOUD's industry-leading technology. At the publishing stream end, the subject (in most cases, a person) in the rectangular video is separated through AI algorithms and transmitted in the RTC network, and rendered at the playing stream end. | Multi-person remote co-hosting, talent show live streaming co-hosting PK, multi-person online study, and other multi-person co-hosting scenarios |
| H.265 | Through the more advanced H.265 encoding technology, higher clarity is provided at the same bitrate. | Higher audio and video call and live streaming experience required under poor network environments, sensitive to bandwidth |
Live Streaming Capabilities
Basic Features
| Basic Features | Feature Description | Use Cases |
|---|---|---|
| Stream Mixing | Mix multiple video streams from multiple people into one stream, so that you only need to pull one stream to see the images of all members in the room and hear the sounds of all members in the room. | Multi-person call host co-hosting |
| Use CDN for Live Streaming | Unified access to multiple CDN capabilities. This function supports publishing 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 latency |
| CDN Stream Publishing Authentication | To prevent attackers from stealing the developer's publishing URL address to use elsewhere, or forging the developer's server to generate the publishing URL address, thereby causing traffic loss, you can configure CDN stream publishing authentication through the ZEGOCLOUD Console. When authentication is enabled, relevant authentication parameters need to be spliced into the publishing URL address, otherwise the stream cannot be published. | - |
| Playing Stream by URL | When the publishing end uses third-party publishing tools (such as OBS software, IP Camera, etc.) to push the stream to CDN, or uses ZEGO SDK to relay the audio and video screen to third-party CDN through the CDN relaying function, you can use the method of directly passing in the URL address to play the stream. | Third-party live streaming screen acquisition |
Other Capabilities
Basic Features
