* @remarks
|
|
* The rate control library is a global library across various codecs. It
|
|
* anticipates certain structures definitions. Those definitions are to be
|
|
* imported from global workspace. Instead of that, the structures needed for
|
|
* rc library are copied in to this file and exported to rc library. If the
|
|
* structures / enums / ... in the global workspace change, this file also needs
|
|
* to be modified accordingly.
