Release notes

This document tracks important changes and improvements to the Cloud Transcoding.

Released on October 1, 2025.

This is the first release of Agora Cloud Transcoding, a cloud-based service that transcodes, mixes, and composites real-time audio and video streams on the server side before publishing them back to RTC channels.

• Low energy consumption for client devices
  Offload stream processing to the server before publishing to the RTC channel. This reduces CPU/GPU load on audience devices, especially those with limited performance.

• Low bitrate streaming for poor network conditions
  Improve video fluency and reliability under weak downlink conditions by mixing audio, combining images, and transcoding into low-bitrate streams. Ideal for audiences subscribing to multiple hosts or single HD streams.

• Cross-platform compatibility
  Support for standard H.264 and VP8 encoding ensures consistent playback across platforms. Host source streams from Native platforms can be converted to VP8 for optimized Web viewing.

• Automated stream processing workflow
  Automatically subscribe to specified user streams in RTC channels based on UID configuration. The service handles transcoding, audio mixing, and video compositing, then republishes processed streams back to the channel.

• Reduced bandwidth and simplified integration
  Viewers no longer need to subscribe to multiple host streams individually. This reduces downstream bandwidth usage and lowers development complexity with fewer API calls and streamlined workflows.
