Release & Upgrade Notes

Below, you’ll find the release notes for the latest version of the Genvid MILE SDK. This section also includes release notes from previous versions of the SDK and instructions for upgrading earlier versions.

Genvid MILE SDK 1.47.1

Welcome to Genvid MILE SDK 1.47.1. This release is ready and stable for integration and can be used for local development and limited cloud deployment. We are still missing some features for a complete production deployment which can be provided through other software. Please contact us from our support page if you’re planning a production deployment.

We are committed to a regular pace for our releases until we get all the features done for a comfortable production deployment. We work to ensure a smooth upgrade between releases and provide as much backward compatibility support as possible. If you encounter any problems, check the list of Known Issues below or contact us from our support page.

Major Fixes and Changes

No major changes provided in this release.

Minor Changes and Other Fixes

  • [sdk] Fixed an issue which caused a log spam of TimeSlotOutdated errors.

  • [sdk] Fixed an issue where the number of pending streams would grow after a few cycles of streams creation/destuction.

  • [gvencode] Fixed and issue where restarting the game without restarting the services introduces a desynchronization between the audio and video streams.

  • [gvencode] Fixed an issue where gvencode failed to properly manage IPv6 addresses.

  • [websdk] Fixed an issue where protobufjs uses the eval function that can cause CSP issues or messages.

Known Issues

Missing RemoteGUI services in Studio RemoteGUI

If the Ingest service is deployed, it will not be accessible via the RemoteGUI menu in Studio. The same will occurs if there are more than one instance of a game deployed.

This restriction will be fixed in a future release.

Twitch Extension Sample works only with three.js version r149

Currently, the Twitch Extension Sample is only compatible with the library three.js version r149. Make sure to only use this version and not a more recent one.

This restriction will be fixed in a future release.

Only one application with the Genvid MILE SDK integrated may run at a time if not launched using Nomad.

If an application using the Genvid MILE SDK is launched without Nomad, a default session name is assigned to it. This is useful when testing your application in the Unity engine, Unreal engine, or booting your application manually.

Currently, the Genvid MILE SDK is unable to support multiple applications launched this way unless you change the environment variable GENVID_SESSION_NAME to a unique name. You can also launch your applications via Nomad to avoid this issue.

We will fix this in a future release.

Streaming to an iOS device with the Standalone player is currently not functional.

Streaming to an iOS device (iPhones and iPads) with the Standalone player is currently not functional. This issue will be fixed in a future release.

Studio UI becomes unresponsive.

In a case where bins and/or NATS services became unhealthy, the Studio UI will became unresponsive

As a workaround, restart the Studio job once the bins and NATS jobs are back to healthy states.

On Azure, the audio and video streams may become de-synchronized.

When capturing a video stream at 60 FPS on Azure, the audio stream slowly becomes de-synchronized compared to the video stream.

The Unreal plugin may cause duplicated events if Unreal is used in Client-Server mode.

When using the Unreal Plugin with Unreal in Client-Server mode, events may be duplicated. This can cause Blueprints to trigger multiple times and notifications to stop being sent to the clients.

Workaround

As a workaround, set the GENVID_UNREAL_PLUGIN_DISABLED environment variable to 1 in the Nomad template of the server job.

This disables the Genvid MILE SDK server-side.

Limitations

Missing proper support for partial Event Summaries in engine plugins

Although the flag is exposed, the current engine plugins miss proper support to distinguish between partial and final Event Summaries.

This restriction will be removed in a future release.

Studio RemoteGUI required trusted access

Studio RemoteGUI still required trusted access to the server to be available on the cloud. If you don’t have such access, the connection will be refused.

This restriction will be removed in a future release.

Loading configurations in the incorrect order can overwrite values.

Whether you’re using SSL on a cloud or a local cluster, if you load youtube.sample.hcl before loading the web sample, the web sample will overwrite the value associated with the embed_ssl from the web.hcl file.

Large NTP time offsets will prevent the stream from playing.

If you encounter large NTP time offsets, your stream may stop playing. As a workaround, make sure that the game machine is configured to update its clock automatically. For local configurations, replace the AWS IP address with pool.ntp.org.

See the AWS configuration section for more information.

Studio can’t take inputs of the same control from multiple windows.

If Studio is opened in more than one browser window and inputs are received from different sources to one control, the final value will then bounce between the different inputs instead of updating it to the latest one. For example, in Audio Mixer Widget, if a user changes the slider of Master Gain to 20 db and another user then changes it to 0 db, the slider handle will bounce between 20 db and 0 db instead of being set to 0 db.

Sending input from multiple Studio windows to one control is not recommended until we resolve the issue.

The SDK clamps framerates under 1.0.

To prevent issues, we raised the lower limit for the framerate to 1.0 for any stream. The SDK will clamp the value to 1.0 FPS if it’s less than 1.0.
