MpegFrameDecoder Class
Properties
StereoMode StereoMode[Get]
Stereo mode used in decoding.
Member Functions
MpegFrameDecoder ( )
void SetEQ
( float [] eq )
Set the equalizer.
Parameters
eq
The equalizer, represented by an array of 32 adjustments in dB.
int DecodeFrame
( IMpegFrame frame,
byte [] dest,
int destOffset )
Decode the Mpeg frame into provided buffer. Do exactly the same as DecodeFrame(IMpegFrame, float[], int) except that the data is written in type as byte array, while still representing single-precision float (in local endian).
Parameters
frame
The Mpeg frame to be decoded.
dest
Destination buffer. Decoded PCM (single-precision floating point array) will be written into it.
destOffset
Writing offset on the destination buffer.
Returns
int DecodeFrame
( IMpegFrame frame,
float [] dest,
int destOffset )
Decode the Mpeg frame into provided buffer. Result varies with different StereoMode:
- For NLayer.StereoMode.Both, sample data on both two channels will occur in turn (left first).
- For NLayer.StereoMode.LeftOnly and NLayer.StereoMode.RightOnly, only data on specified channel will occur.
- For NLayer.StereoMode.DownmixToMono, two channels will be down-mixed into single channel.
Parameters
frame
The Mpeg frame to be decoded.
dest
Destination buffer. Decoded PCM (single-precision floating point array) will be written into it.
destOffset
Writing offset on the destination buffer.
Returns
void Reset ( )
Reset the decoder.
