EncodeFormats.WMA.GetEncodingCBRCount method

Previous pageReturn to chapter overviewNext page

Remarks

 

Retrieves the number of encoding bitrates (Constant Bitrate or CBR) supported by Windows Media components for a given frequency, number of channels and encoding format.

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

 

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.
