|
|
* \brief
|
|
* This module describes the three encoder layers provided by libFLAC++.
|
|
*
|
|
* The libFLAC++ encoder classes are object wrappers around their
|
|
* counterparts in libFLAC. All three encoding layers available in
|
|
* libFLAC are also provided here. The interface is very similar;
|
|
* make sure to read the \link flac_encoder libFLAC encoder module \endlink.
|
|
*
|
|
* The only real difference here is that instead of passing in C function
|
|
* pointers for callbacks, you inherit from the encoder class and provide
|
|
* implementations for the callbacks in the derived class; because of this
|
|
* there is no need for a 'client_data' property.
