ProtectedconstructorWhy frames are encoded in-process, or null while the worker is used.
Whether an encode worker is running now.
Where frames are encoded now: on the worker, or in-process after the host gave up on it.
The worker script the default factory starts.
StaticInstanceThis thread's host. Creating it starts nothing: the first frame does.
Replaces the settings given (tests, diagnostics). Takes effect at the next spawn.
Encodes one frame on the encode worker (spawning it when none runs), or in-process after the fallback. Copies the frame's planes before it returns. Rejects when the frame cannot be encoded or the worker fails with it in flight.
The Global Object Store is a place to store global objects that need to be shared across the application. Depending on the execution environment, this could be the window object in a browser, or the global object in a node environment, or something else in other contexts. The key here is that in some cases static variables are not truly shared because it is possible that a given class might have copies of its code in multiple paths in a deployed application. This approach ensures that no matter how many code copies might exist, there is only one instance of the object in question by using the Global Object Store.
Frames waiting on the worker (every room on this thread), and worker failures so far.
Back to a fresh host (tests): stops the worker, rejects what is pending, clears the failure count, the fallback and the settings.
Protected StaticgetReturns the singleton instance of the class. If the instance does not exist, it is created and stored in the Global Object Store. If className is provided it will be used as part of the key in the Global Object Store, otherwise the actual class name will be used. NOTE: the class name used by default is the lowest level of the object hierarchy, so if you have a class that extends another class, the lowest level class name will be used.
OptionalclassName: string
The encode worker of this thread and the frames waiting on it. One per thread (
BaseSingletonkeys on the thread's global object), shared by every watching room client on that thread. See the file header for its lifecycle and failure policy.
