+// This class provides a way to split a single media source into multiple sources.
+// The constructor takes in the real mediaSource and createClient() can then be
+// used to create multiple sources served from this real mediaSource.
+//
+// Usage:
+// - Create MediaSourceSplitter by passing in a real mediaSource from which
+// multiple duplicate channels are needed.
+// - Create a client using createClient() and use it as any other mediaSource.
+//
+// Note that multiple clients can be created using createClient() and
+// started/stopped in any order. MediaSourceSplitter stops the real source only
+// when all clients have been stopped.
+//
+// If a new client is created/started after some existing clients have already
+// started, the new client will start getting its read frames from the current
+// time.
