Alibaba Cloud RTC provides the bypass and push feature. You can synchronize the images of the channels during real-time audio and video calls to the cloud for mixing, and ingest the mixed live streams to third-party Alibaba Cloud Content Delivery Network or Alibaba Cloud ApsaraVideo Live. By reading this article, you can quickly understand the basic concepts and functional descriptions of bypass push.
Overall architecture
After you integrate Alibaba Cloud RTC on all terminals (PC, mobile terminal, and Web) and implement audio and video calls, you can use the bypass ingest service to perform operations such as mixing, transcoding, and encoding in the cloud. Then, the bypass ingest video stream is generated and pushed to the ApsaraVideo Live for live viewing with large-scale downstream acceleration.
