Public Shared Function BASS_WMA_EncodeOpenNetworkMulti ( 
	freq As Integer,
	chans As Integer,
	flags As BASSWMAEncode,
	bitrates As Integer(),
	port As Integer,
	clients As Integer
) As Integer

Parameters

freq

Type: SystemInt32
The sample rate in Hz, or a BASS channel handle if the BASS_WMA_ENCODE_SOURCE flag is specified.

chans

Type: SystemInt32
The number of channels (1=mono, 2=stereo, etc.).

flags

Type: Un4seen.Bass.AddOn.WmaBASSWMAEncode
Any combination of these flags (see BASSWMAEncode):

BASS_SAMPLE_8BITS	8-bit sample data. If neither this or the BASS_SAMPLE_FLOAT flags are specified, then 16-bit data is expected.
BASS_SAMPLE_FLOAT	32-bit floating-point sample data.
BASS_WMA_ENCODE_STANDARD	Use standard WMA encoding. If neither this or the BASS_WMA_ENCODE_PRO flag is specified, then either codec could be used (whichever supports the requested sample format and bitrate).
BASS_WMA_ENCODE_PRO	Use WMA Professional encoding.
BASS_WMA_ENCODE_VOICE	Use WMA voice encoding.
BASS_WMA_ENCODE_VOICE_MIXED	UUse WMA voice encoding in mixed mode.
BASS_WMA_ENCODE_PCM	Write uncompressed PCM data in an ASF container. bitrate is ignored except that it should be non-0.
BASS_WMA_ENCODE_24BIT	Encode in 24-bit, else 16-bit. 24-bit encoding requires WMA Pro.
BASS_WMA_ENCODE_SCRIPT	Enable the specification of tags mid-stream (after encoding has begun).
BASS_WMA_ENCODE_SOURCE	Use the BASS channel with the handle in freq as the encoder's source. The chansparameter is ignored, as are the BASS_SAMPLE_8BITS and BASS_SAMPLE_FLOAT flags. If the BASSenc add-on is loaded, then the BASS_CONFIG_ENCODE_PRIORITY setting is used to determine where in the channel's DSP chain the encoding is performed, otherwise priority -1000 is used.

bitrates

Type: SystemInt32
Array of encoding bitrates (in bits per second, e.g. 128000) to use, terminated with a 0 element (so the number of elements in the array must be one more than the effective bitrates used).

port

Type: SystemInt32
The port number for clients to conenct to... 0 = let the system choose a port.

clients

Type: SystemInt32
The maximum number of clients (up to 50) that can be connected.

Return Value

When encoding/broadcasting in multiple bitrates, the user will automatically get the best available bitrate for their bandwidth.

The WMA codec expects 16-bit or 24-bit sample data depending on the BASS_WMA_ENCODE_24BIT flag, but BASSWMA will accept 8-bit, 16-bit or floating-point data, and convert it to the appropriate format. Use BASS_WMA_EncodeGetRates(Int32, Int32, BASSWMAEncode) to retrieve a list of the encoding bitrates available for a specific sample format. VBR encoding is not recommended for network encoding.

int[] bitrates = {128000, 64000, 0}; // the bitrates
int encoder = BassWma.BASS_WMA_EncodeOpenNetworkMulti( 44100, 2, 
                      BASSWMAEncode.BASS_WMA_ENCODE_DEFAULT, bitrates, 4711, 5);

Dim bitrates As Integer() = {128000, 64000, 0} ' the bitrates
Dim encoder As Integer = BassWma.BASS_WMA_EncodeOpenNetworkMulti(44100, 2, 
                                 BASSWMAEncode.BASS_WMA_ENCODE_DEFAULT, bitrates, 4711, 5)
