BASS_WMA_EncodeOpenPublishMulti

Initializes WMA encoding to a publishing point on a Windows Media server, using multiple bitrates.

HWMENCODE BASS_WMA_EncodeOpenPublishMulti(
    DWORD freq,
    DWORD chans,
    DWORD flags,
    DWORD *bitrates,
    char *url,
    char *user,
    char *pass
);

Parameters

freq

The sample rate, or a BASS channel handle if the BASS_WMA_ENCODE_SOURCE flag is specified.

chans

The number of channels. More than stereo requires WMA Pro or PCM.

flags

A combination of these flags.

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_SOURCE	Use 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_STANDARD	Use standard WMA encoding. If neither this or the BASS_WMA_ENCODE_PRO flag (nor the BASS_WMA_ENCODE_PCM flag) is specified, then either WMA codec could be used, depending on which supports the requested sample format and bitrate.
BASS_WMA_ENCODE_PRO	Use WMA Pro encoding.
BASS_WMA_ENCODE_PCM	Write uncompressed PCM data in an ASF container. The bitrates content 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 or PCM.
BASS_WMA_ENCODE_SCRIPT	Enable the specification of tags mid-stream (after encoding has begun).
BASS_UNICODE	url, user and pass are Unicode (UTF-16).

bitrates

Array of encoding bitrates to use, terminated with a 0.

url

URL of the publishing point on the Windows Media server.

user

Username to use in connecting to the server... if either this or pass is NULL, then no username/password is sent to the server.

pass

Password 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_WMA	The Windows Media modules (v9 or above) are not installed.
BASS_ERROR_NOTAVAIL	No codec could be found to support the requested sample format and bitrate.
BASS_ERROR_FILEOPEN	Could not connect to the server.
BASS_ERROR_WMA_DENIED	Access was denied. Check the user and pass.
BASS_ERROR_WMA_PUBINIT	The 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_UNKNOWN	Some other mystery problem!

Remarks

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.
