Version 21.5.0 GA

What's new in this release?

• Support for a virtual audio source
• VidyoClient now supports a virtual audio source. Using this feature, an application can inject audio frames into a conference using VidyoConnector APIs.
• Support for content sharing with audio
• VidyoClient can now capture audio coming from the system default output device and send it to all the participants in the conference. Therefore, when users share applications that play audio, such as YouTube or the Windows Media Player, the other conference participants will be able to both see video and hear audio from that shared application.
• This feature is supported only on high-end Windows systems. Support for macOS will be added in a future release.
• Dynamic linking of SDK for image segmentation
• The image segmentation functionality (for example, background blur and virtual background) is an optional feature. That being so, this enhancement allows the application to exclude the segmentation SDK when running with VidyoClient if the image segmentation functionality is not used in the application.

VidyoClient API Binary Library version 21.5.0 - known issues
Key	Summary
IO-3500 and IO-3466	When the content sharing with audio feature is used during a conference, VidyoClient will share the audio being played to the speaker selected as the default speaker in the operating system. Therefore, you must ensure that no other application other than the application you are sharing is playing audio to the speaker.
IO-3456	Audio is shared only from the operating system's default output device. Therefore, if you want to share audio in your conference, you must select the default device as your audio playback device on the application from which you want to share audio. If a device other than the OS default device is selected, audio won't be shared.
