This version reduces the size of the SDK by removing the Vonage Media Library code. In order to use methods that use the Vonage Media Library, you must load the Vonage Media Library separately from the Vonage Video macOS SDK. This includes using the otc_publisher_set_video_transformers() and otc_publisher_set_audio_transformers() functions to apply audio and video transformers to the stream. For more information, see Vonage Media Library integration.

The following are known issues:
Emojis unexpectedly appear in videos in macOS 14 (Sonoma). This is a result of the new Apple Reactions feature. At this time, there is no API or programmatic to turn this off. End-users must disable it during a video session by clicking the green video camera icon in the Mac's menu bar and then deselecting Reactions.
If a system proxy is configured, the SDK will not use it.
In some cases, Bluetooth is not being routed. We are looking into the issue.
