 // The module is largely intended to process video streams, except functionality
 // provided by static functions which operate independent of previous frames. It
 // is recommended, but not required that a unique instance be used for each
 // concurrently processed stream. Similarly, it is recommended to call Reset()
 // before switching to a new stream, but this is not absolutely required.
 //
 // The module provides basic thread safety by permitting only a single function
 // to execute concurrently.
