COM Objects > WMA object > Methods > EncodeFormats.WMA.GetEncodingVBRQualitiesCount method

Remarks

Retrieves the number of supported encoding qualities (for Variable Bit Rate support) for a given native resampling format.

Each of the supported qualities can be obtained at a later time using the EncodeFormats.WMA.GetEncodingVBRQuality method.

This method can be called only when the Status property is different from RECORD_STATUS_NOT_READY.

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

For further information about available encoding formats see the EncodeFormats object.

Syntax

[Visual Basic]

control.EncodeFormats.WMA.GetEncodingVBRQualitiesCount (

nInputDevice as integer,

nFormatIndex as integer

) as integer

[C++]

short control.EncodeFormats.WMA.GetEncodingVBRQualitiesCount (

short nInputDevice,

short nFormatIndex

);

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

Return value

Value	Meaning

Negative value	An error occurred. Check the LastError property value in order to see the last error.
> 0	The number of supported encoding Variable Bit Rate qualities.
