// since the stream constructors have complex dependencies on global singletons.
// The key behavior we want to test is:
// 1. Function returns early if disposing_ is true
// 2. Function iterates through publishers_ and calls start() on each
// 3. Function iterates through players_ and calls start() on each
// 4. Function returns error if any start() call fails
// 5. Function logs appropriate trace messages
// The first two scenarios above already test the core logic:
// - Early return when disposing_ is true
// - Success when no publishers/players exist
// - The trace logging happens (though we can't easily verify it in unit tests)
// The function's main responsibility is to iterate through the maps and call start()
// on each stream. Since we've verified the basic flow works, and the iteration
// logic is straightforward, this provides good coverage of the typical use case.
