Release notes

This page provides the release notes for Media Gateway.

• Low-bitrate high-quality streaming

  Video transcoding now supports low-bitrate high-quality streaming through PVC (Perceptual Video Coding) and Super Resolution features. Enable these features when creating, resetting, or updating stream configuration templates using the pvc and superResolution objects under transcoding.video.advancedOptions.
  For configuration details, see PVC and Super Quality configuration.

• Adaptive Bitrate (ABR)

  Stream configuration templates now support ABR functionality. With video transcoding enabled, configure multi-bitrate encoding through the simulcastStreamLayers object when creating, resetting, or updating templates.
  For configuration details, see Enable Adaptive Bitrate.

• SRT streaming protocol support

  Gateway nodes now support the SRT (Secure Reliable Transport) streaming protocol with the following codec formats:

  • Video: H.264, H.265
