EncodeFormats.WMA.GetEncodingVBRQuality method

EncodeFormats.WMA.GetEncodingVBRQuality method

Remarks

Retrieves a specific encoding quality (for Variable Bit Rate support) for a given native resampling format.

The number of available bitrates can be obtained using the EncodeFormats.WMA.GetEncodingVBRQualitiesCount method.

This method can be called only after receiving the InputFormatsAvailable event.

For further details about encoding in WMA format refer to the EncodeWMA class section.

For further information about available encoding formats see the EncodeFormatsMan class.

Syntax

[Visual Basic]

Public Function GetEncodingVBRQuality (

nInputDevice as Int16,

nFormatIndex as Int16,

nQualityIndex as Int16

) as Int32

[C#]

public Int32 GetEncodingVBRQuality (

Int16 nInputDevice,

Int16 nFormatIndex,

Int16 nQualityIndex

);

[C++]

public: Int32 GetEncodingVBRQuality (

Int16 nInputDevice,

Int16 nFormatIndex,

Int16 nQualityIndex

);

Parameter	Description

nInputDevice	Number representing the zero-based index of the input device
nFormatIndex	Number representing the zero-based index of the native resampling format. The number of native resampling formats supported by the given input device can be obtained using the EncodeFormats.ResampleNativeFormatsGetCount method and their friendly description can be obtained using the EncodeFormats.ResampleNativeFormatGetDesc method.
nQualityIndex	Number representing the zero-based index of the bitrate quality

Return value

Value	Meaning

Negative value	An error occurred. Check the LastError property value in order to see the last error.
> 0	The requested encoding Variable Bit Rate quality: the range of supported values is from 0 to 100.
