// Principal class of the Broadcast Upload Extension (ReplayKit) that lets the iOS user share their screen.
|
||
|
|
//
|
||
|
|
// HOW IT WORKS: when the user starts a system broadcast, iOS launches THIS extension. LiveKit's LKSampleHandler
|
||
|
|
// does everything — on broadcastStarted it opens an IPC socket in the shared App Group (group.com.bizgaze.connect)
|
||
|
|
// and streams the ReplayKit sample buffers to the MAIN app, whose LiveKit connection publishes them as a
|
||
|
|
// screen-share track. The extension itself never creates a Room / initialises WebRTC, so it stays well under the
|
||
|
|
// 50 MB extension memory limit. So this subclass can be empty.
|
||
|
|
//
|
||
|
|
// The extension finds the app group + reports state to the app via LiveKit's Darwin-notification/socket
|
||
|
|
// convention, keyed off this extension's bundle id (com.bizgaze.connect.broadcast) and the default app group
|
||
|
|
// group.<appBundleId>. Both are also set explicitly on the app side (RTCScreenSharingExtension /
|
||
|
|
// RTCAppGroupIdentifier in Info.plist) so there's no ambiguity.
