New Virtual Classroom Major Version - Performance Build (01/01/2019)

We've rolled our a new virtual classroom build across all global locations. This 'performance build' was created to fix the issues affecting our users and improve overall class delivery experience with our new backend updates and improvements.

Bug Fixes & Improvements:

  • [NEW] Show logo in video recordings
  • [FIX] Fix Chrome browser's "audioplay" policy issue which was corrupting the audio stream resulting in no video recordings
  • [FIX] Recording is not produced when browser tab is closed in the middle of a recording session by the instructor
  • [NEW] Avail BrainCert's new dynamic SFU/MCU engine (codename 'Fast Tiger') that is highly tuned to provide an immersive audio and video experience. All 15 of our global locations is now powered by this new technology.
  • [IMPROVEMENT] Default video tool window size should fit the video without any dark areas on the left and right side of the recorded videos output file
  • [IMPROVEMENT] "Enhanced video recorder" feature that automatically recovers corrupted or partially recorded videos by checking the file integrity and compare the data points from the session and produce a video recording file
  • [FIX] Attendees were able to control video player even when when allow control toggle is turned off by the instructor
  • [FIX] Whiteboard toolbar is not shifted to the right side when using RTL interface language such as Arabic and Hebrew.
  • [FIX] Pencil Tool is changed on Select tool when document is uploaded
  • [FIX] WolframAlpha was not producing output on the whiteboard
  • [FIX] Settings windows are partly displayed out of the screen on Android devices
  • [IMPROVEMENT] Rework Net Speed Check
  • [IMPROVEMENT] New feature to resize media player window by dragging the right bottom of the window and resize it. This is useful when you want to have a bigger window to watch streaming videos using media player
  • [IMPROVEMENT] Increase the window size of the media player popup
  • [IMPROVEMENT] Improve 'capacity planner' tool that comes into play when you schedule a live session. This tool helps to create a 'blueprint' for the session by analyzing various metrics such as compute resources available in a global datacenter, optimal network path required to achieve very low-latency, switch to dynamic SFU or MCU configuration (core technology), low bandwidth optimizations and congestion control.

Planned Accomplishment in next version (2-3 weeks from now)

  • Add expand button for media player pop-up to enlarge it in whiteboard area (similar to code editor)
  • Add ability for presenter to hide Whiteboard tabs from students by locking and unlocking specific boards
  • Improve document display for screens with high DPI so all uploaded documents look better on mobile devices

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

'Auto select nearest datacenter region' fix and the new 'Capacity' feature in virtual classroom

The previously reported issue of all the traffic going to Dallas, TX location when using 'auto select nearest location' (isRegion=0 API call) feature is now fixed. When you schedule a live class and leave the default isRegion=0 option, it will now assign class to the nearest datacenter location and/or takes the least congestion free network path in to consideration.

Furthermore, we've improved this feature to include 'capacity' in to consideration. When you schedule a class with high number of attendees, the built-in 'capacity' tool will find the best performing servers from our cluster pool and reserve it for the class to offer the best possible performance.

Introducing Amsterdam Data Center

We're excited to announce the launch our new virtual classroom region: Amsterdam, Netherlands! This brings our datacenter coverage to 15 global locations worldwide making BrainCert the largest virtual classroom provider!

As always, we bring the same high-performance and reliable technology stack that we have developed over the years and that is in use in all our previous data centers. Our latest Amsterdam datacenter offers high performance and low latency performance to the rest of the world and provides fault tolerance to other European locations that BrainCert offers - Frankfurt, London, Milan and Paris.

Use isRegion=15 to use the new Amsterdam location.

VC issues related to 'isVideo=1' and 'auto select datacenter location' features

We are currently investigating issues related to session recording and intelligent routing to nearest datacenter feature.

1) Customers are advised NOT to use isVideo=1 parameter that concatenate multiple video files into a single video file. Due to a bug with current version, the final video is not produced in few situations. This has been fixed in the upcoming major version anticipated in 2-3 weeks.

2) "Auto select nearest datacenter location" feature is routing most of the classes to Dallas, TX location which maybe congested due to high volume of traffic. Customers are advised to manually select a datacenter location.

isExtend API call

isExtend API call was showing up incorrectly in schedule a new live class documentation. We removed it from this documentation page.

The correct way to invoke this call is from GetClassLaunch API call. The correct info is here.

We apologize for the inconvenience this may have caused.

Important changes to the content library

The content library in the E-Learning Platform has been shared by other platforms such as 'Virtual classroom API' subscribers and 'Meeting Room' users. To prevent this, we have rolled out a new feature to select your specific platform to upload and manage contents focusing on privacy protection, data segregation, and content security.

In the content library, click on the dropdown menu and select "Virtual Classroom API" to manage and upload your contents.

Bug Fixes and Improvements

  • [NEW] Newly launched large-scale, global TURN Servers (NAT Traversal) now greatly improve connectivity when users are behind enterprise corporate firewalls that blocks certain UDP and TCP packets and known ports. We've tested this with customers coming from banking sector and corporate NAT environments and experienced 99.99% success with the audio and video streams.
  • [FIX] isVideo=1 not producing final video. Now, it should concatenate all session recordings into a single file and produce final video file. Please note when instructor close the session before the end time, it will wait 300 seconds and then produce a final video assuming instructor has left the session.
  • [FIX] Fix issue related to some of the uploaded PPT files flashing in the whiteboard.
  • [FIX] End class confirmation popup was appearing behind the global settings popup window (gear icon in left bottom of the app).
