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.
The H.264 codec is not supported. See the video codecs developer guide.
In some cases, Bluetooth is not being routed. We are looking into the issue.
