Description

Methods

Public constructor create(const libName: string = c_lameEncDLL);
 
Public function encode(data: pointer; len: int): int;
 
Public function flush(locked: bool = true): int;
 
Public function open(bitrate: int = 128; cbr: bool = true; resample: int = -1; preset: int = LQP_NOPRESET): int;

Initializates and open the encoder for CBR or ABR.

Parameters
bitrate
Desired bitrate.
cbr
True for CBR, False for ABR, default is True
resample
Resample input stream to specified rate (default is -1, means no resample).
preset
One of LQP_XXX presets. Default is LQP_NOPRESET.
Returns

BE_ERR_SUCCESSFUL in case encoder was successully initialized

Public function openVBR(minBitrate: int = 96; maxBitrate: int = 256; quality: int = 8; resample: int = -1; preset: int = LQP_NOPRESET): int;

Initializates and open the encoder for VBR.

Parameters
minBitrate
Desired minimal bitrate.
maxBitrate
Desired maximum bitrate.
quality
Desired quality from 0 to 10.
resample
Resample input stream to specified sampling rate (default is -1, means no resample).
preset
One of LQP_XXX presets. Default is LQP_NOPRESET.
Returns

BE_ERR_SUCCESSFUL in case encoder was successully initialized

Public procedure BeforeDestruction(); override;
 
Public procedure close();
 
Public procedure getVer(var ver: BE_VERSION);
 
Protected procedure onEncodedData(sampleDelta: uint; data: pointer; len: uint); virtual;
