Error Events
If the event queried is of type NvSciStreamEventType_Error, an error not
            directly triggered by user action occurred in the block. Applications can retrieve the
            error code by  NvSciStreamBlockErrorGet(). If multiple errors occur
            before this retrieval, only the first error code is available. All subsequent errors are
            ignored until the error code is retrieved, with the assumption that they are related to
            the first error.
