General parameter notes (for all methods of this class):
|
||
|
|
@param profile is a filename of an INI file where the encoder settings are stored
|
||
|
|
@param parameters defines the input audio data. For methods where this parameter
|
||
|
|
is optional (default parameter value == 0), it is meant to be passed to optionally
|
||
|
|
limit configuration choices. For example, an AAC encoder could hide surround-sound
|

|
|
encoding options when parameters->channels == 2
