Initializes WMA encoding to a publishing point on a Windows Media server.

    DWORD freq,
    DWORD chans,
    DWORD flags,
    DWORD bitrate,
    char *url,
    char *user,
    char *pass


freqThe sample rate, or a BASS channel handle if the BASS_WMA_ENCODE_SOURCE flag is specified.
chansThe number of channels. More than stereo requires WMA Pro or PCM.
flagsA combination of these flags.
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_SOURCEUse the BASS channel with the handle in freq as the encoder's source. The chans parameter 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.
BASS_WMA_ENCODE_STANDARDUse standard WMA encoding. If neither this or the BASS_WMA_ENCODE_PRO flag (nor the BASS_WMA_ENCODE_VOICE or BASS_WMA_ENCODE_PCM flags) is specified then either WMA codec could be used, depending on which supports the requested sample format and bitrate.
BASS_WMA_ENCODE_VOICEUse WMA voice encoding.
BASS_WMA_ENCODE_VOICE_MIXEDUse WMA voice encoding in mixed mode.
BASS_WMA_ENCODE_PCMWrite uncompressed PCM data in an ASF container. bitrate is ignored.
BASS_WMA_ENCODE_24BITEncode in 24-bit, else 16-bit. 24-bit encoding requires WMA Pro or PCM.
BASS_WMA_ENCODE_SCRIPTEnable the specification of tags mid-stream (after encoding has begun).
BASS_UNICODEurl, user and pass are Unicode (UTF-16).
bitrateThe encoding bitrate.
urlURL of the publishing point on the Windows Media server.
userUsername to use in connecting to the server... if either this or pass is NULL, then no username/password is sent to the server.
passPassword to use in connecting to the server.

Return value

If successful, the new encoder's handle is returned, else FALSE is returned. Use BASS_ErrorGetCode to get the error code.

Error codes

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_WMA_PUBINITThe server connection was not initialized properly. This can happen when connecting to the same server multiple times in quick succession. Try again after waiting a couple of seconds.
BASS_ERROR_UNKNOWNSome other mystery problem!


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 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 to set tags, BASS_WMA_EncodeWrite to encode sample data, and BASS_WMA_EncodeClose to finish encoding and close the connection to the server. If the BASS_WMA_ENCODE_SOURCE flag is used and the source BASS channel is freed then the encoder will be closed automatically.

The BASS_WMA_ENCODE_QUEUE flag is not necessary with this function as the data is always queued and fed to the encoder asynchronously.
