BASS.NET API for the Un4seen BASS Audio LibraryBassWmaBASS_WMA_EncodeOpenPublishMulti Method BASS.NET API for the Un4seen BASS Audio Library
Initializes WMA encoding to a publishing point on a Windows Media server, using multiple bitrates.

This overload implements the Unicode version for url, user and pass. BASS_UNICODE will automatically be added if not set.

Namespace: Un4seen.Bass.AddOn.Wma
Assembly: Bass.Net (in Bass.Net.dll) Version:

public static int BASS_WMA_EncodeOpenPublishMulti(
	int freq,
	int chans,
	BASSWMAEncode flags,
	int[] bitrates,
	string url,
	string user,
	string pass


Type: SystemInt32
The sample rate in Hz, or a BASS channel handle if the BASS_WMA_ENCODE_SOURCE flag is specified.
Type: SystemInt32
The number of channels (1=mono, 2=stereo, etc.).
Type: Un4seen.Bass.AddOn.WmaBASSWMAEncode
Any combination of these flags (see BASSWMAEncode):
BASS_SAMPLE_8BITS8-bit sample data. If neither this or the BASS_SAMPLE_FLOAT flags are specified, then 16-bit data is expected.
BASS_SAMPLE_FLOAT32-bit floating-point sample data.
BASS_WMA_ENCODE_STANDARDUse 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_PROUse WMA Professional encoding.
BASS_WMA_ENCODE_PCMWrite uncompressed PCM data in an ASF container. bitrate is ignored except that it should be non-0.
BASS_WMA_ENCODE_24BITEncode in 24-bit, else 16-bit. 24-bit encoding requires WMA Pro.
BASS_WMA_ENCODE_SCRIPTEnable the specification of tags mid-stream (after encoding has begun).
BASS_WMA_ENCODE_SOURCEUse 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.
Type: SystemInt32
Array of encoding bitrates to use, terminated with a 0 (in bits per second, e.g. 128000).
Type: SystemString
URL of the publishing point on the Windows Media server.
Type: SystemString
Username to use in connecting to the server... if either this or pass is , then no username/password is sent to the server.
Type: SystemString
Password to use in connecting to the server.

Return Value

Type: Int32
If succesful, the new encoder's handle is returned, else 0 is returned. Use BASS_ErrorGetCode to get the error code.

This function is identical to BASS_WMA_EncodeOpenPublish, but with the additional ability to specify multiple bitrates.

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.

Use BASS_WMA_EncodeSetTag(Int32, IntPtr, IntPtr, BASSWMATag) for each tag you wish to set.

Use BASS_WMA_EncodeWrite(Int32, IntPtr, Int32) to encode sample data, and BASS_WMA_EncodeClose(Int32) to finish encoding and close the network port.

ERROR CODEDescription
BASS_ERROR_WMAThe Windows Media modules (v9 or above) are not installed.
BASS_ERROR_NOTAVAILNo codec could be found to support the requested sample format and bitrate.
BASS_ERROR_FILEOPENCould not connect to the server.
BASS_ERROR_WMA_DENIEDAccess was denied. Check the user and pass.
BASS_ERROR_UNKNOWNSome other mystery problem!
