3003A module cannot be loaded because it has not been added to the player core.
This error occurs when a feature is used that needs a specific module to be loaded, but that module has not been added to the player. For example, when playing back a WebM stream, the ContainerWebM module is needed. Should that module not be present, this error will be thrown.
Please make sure all the required modules are loaded. Refer to ModuleName to determine, which modules are needed to supported the desired features.
