INCLUDE DESCRIPTION
|
||
|
|
|
||
|
|
Main header file for the Packet Video AMR Wide Band decoder library. The
|
||
|
|
constants, structures, and functions defined within this file, along with
|
||
|
|
a basic data types header file, is all that is needed to use and communicate
|
||
|
|
with the library. The internal data structures within the library are
|
||
|
|
purposely hidden.
|
||
|
|
|
||
|
|
---* Need description of the input buffering. *-------
|
||
|
|
|
||
|
|
---* Need an example of calling the library here *----
