VALT 6.7.6-1

October 14th, 2026

Application

• WebRTC
  • Added a TURN relay so WebRTC live streams only need UDP port 3478 instead of a large range of UDP ports
  • Fixed issue where WebRTC live streams did not play for some cameras depending on the camera's audio codec, bit rate, or sample rate settings
  • Fixed issue where cameras with audio disabled did not show video over WebRTC
• Observe views
  • Fixed issue where a camera could not be removed from a view
• SSO
  • Updated SSO login to use the HTTP-Redirect binding when the identity provider supports it
  • Fixed issue where SSO login did not complete with identity providers that only support the HTTP-POST binding
• Fixed issue in Admin > VALT Cue where a Cue Session's configuration did not show all of the evaluation template's field types
• Improved handling of transcription service credentials

Technical

• Added a TURN relay server (valt_coturn) Docker container
  • WebRTC live streams now connect through the TURN relay on UDP port 3478
  • Firewalls between viewers and VALT must allow inbound UDP port 3478 to the Application Server and each Media Server
  • The UDP port range 6750-15000 is no longer used for WebRTC
  • When upgrading a Media Server, the installer prompts for the TURN shared secret configured on the Application Server
• Updated packages and frameworks
  • Wowza Docker Image: Wowza Streaming Engine 4.12.0
