Version 21.4.0 GA

What's new in this release?

  • Redundancy support for Opus
  • This release adds RED support for the Opus codec. RED, which stands for REDundant coding, is an RTP payload format defined in RFC 2198 for encoding redundant audio or video data.
  • Sending redundant data enables the recovery of packets lost under lossy network conditions. If a packet is lost, the missing information may be reconstructed at the receiver from the redundant data that arrives in the following packet(s).
  • iOS device selection and audio routing enhancements
  • If you're an iOS user, you'll find that this release enables you to more easily and successfully select and switch between your microphone and speaker devices. In addition, you'll notice that we've improved the audio routing, reducing the chance that you'll run into audio issues on your iOS devices.
