Virtual Classroom - Minor Patch (11/30/2018)

A minor patch for virtual classroom has been updated to fix the following issues and improve overall performance:

  • Fix insert image issue with Firefox browser
  • Chat message window shifting upwards bug with Firefox browser
  • Low volume output in a live virtual classroom session
  • Improve the adaptive bitrate algorithm to deliver the best possible audio & video performance in low bandwidth situations
  • Improve network congestion control feature to improve overall transmission performance and stability
  • Some of the old recurring classes were using old cached DNS hostnames of the VC server clusters in multiple locations. Recent updates has forced everyone to use new backend servers automatically which is transparent to end users. However, few users running very old recurring schedule were affected and this issue has been resolved by pointing to new DNS entries without any further changes
  • Improve recording bandwidth consumption and produce complete recorded video in low bandwidth situations
