BASS_FLAC_StreamCreateURL

Creates a sample stream from an FLAC file on the internet, optionally receiving the downloaded data in a callback function.

HSTREAM BASS_FLAC_StreamCreateURL(
    char *url,
    DWORD offset,
    DWORD flags,
    DOWNLOADPROC *proc,
    void *user
);

Parameters

urlURL of the file to stream. Should begin with "http://" or "https://" or "ftp://".
offsetFile position to start streaming from. This is ignored by some servers, specifically when the file length is unknown.
flagsA combination of these flags.
BASS_SAMPLE_FLOATUse 32-bit floating-point sample data. See Floating-point channels for info.
BASS_SAMPLE_3DEnable 3D functionality. The stream must be mono. The SPEAKER flags cannot be used together with this flag.
BASS_SAMPLE_LOOPLoop the file. This flag can be toggled at any time using BASS_ChannelFlags. This flag is ignored when streaming in blocks (BASS_STREAM_BLOCK).
BASS_STREAM_RESTRATERestrict the download rate of the file, according to the BASS_CONFIG_NET_RESTRATE config setting. If this flag is not used then the file will be downloaded as quickly as possible.
BASS_STREAM_BLOCKOnly keep a block of the downloaded file in memory, determined by the BASS_CONFIG_NET_BUFFER config setting, rather than the whole file. This uses a lot less memory than otherwise, but it is not possible to seek or loop the stream. This flag will be applied automatically when the file length is unknown or over 2GB.
BASS_STREAM_STATUSPass status info (HTTP/ICY tags) from the server to the DOWNLOADPROC callback during connection. This can be useful to determine the reason for a failure.
BASS_STREAM_AUTOFREEAutomatically free the stream when playback ends.
BASS_STREAM_DECODEDecode the sample data, without playing it. Use BASS_ChannelGetData to retrieve decoded sample data. The BASS_SAMPLE_3D, BASS_STREAM_AUTOFREE and SPEAKER flags cannot be used together with this flag.
BASS_SPEAKER_xxxSpeaker assignment flags. These flags have no effect when the stream is more than stereo.
BASS_UNICODEurl is in UTF-16 form. Otherwise it is ANSI on Windows and UTF-8 on other platforms.
procCallback function to receive the file as it is downloaded... NULL = no callback.
userUser instance data to pass to the callback function.

Return value

If successful, the new stream's handle is returned, else 0 is returned. Use BASS_ErrorGetCode to get the error code.
