BASS_Encode_FLAC_StartFile

Sets up a FLAC encoder on a channel, writing the output to a file. 

HENCODE BASS_Encode_FLAC_StartFile(
    DWORD handle,
    char *options,
    DWORD flags,
    char *filename
);

Parameters

handleThe channel handle... a HSTREAM, HMUSIC, or HRECORD.
optionsEncoder options... NULL = use defaults. The following reference FLAC encoder style options are supported: --ogg, --serial-number, --until, -S / --seekpoint, --no-seektable, -T / --tag, --picture, -P / --padding, --no-padding, -b / --blocksize, -V / --verify, --limit-min-bitrate, --fast, --best, -0 / --compression-level-0 and the other compression level options. See the FLAC documentation for details on the aforementioned options and defaults. Anything else that is included will be ignored.
flagsThe flags supported by BASS_Encode_StartUser may be used here. FLAC does not support floating-point sample data, so that must be converted to integer before it is fed to the encoder. If none of the floating-point conversion flags are specified, then one will be applied automatically based on the channel's origres value (available from BASS_ChannelGetInfo) or BASS_ENCODE_FP_16BIT if that is undefined.
filenameOutput filename... NULL = no output file.

Return value

The encoder handle is returned if the encoder is successfully started, else 0 is returned. Use BASS_ErrorGetCode to get the error code.

Error codes

BASS_ERROR_HANDLEhandle is not valid.
BASS_ERROR_FORMATThe channel's sample format is not supported by the encoder.
BASS_ERROR_CREATEThe file could not be created.
BASS_ERROR_UNKNOWNSome other mystery problem!

Remarks

BASS_Encode_StartUser is used internally to apply the encoder to the source channel, so the remarks in its documentation also apply to this function.

The evenly spaced seekpoint options (with a "x" or "s" suffix), including the 10s default spacing, are only applicable when the "--until" option is used to tell how long the encoding will be. "--until=-0" can be used for the full length of the source channel, according to BASS_ChannelGetLength.

Tags/comments should be in UTF-8 form. This function will take care of that when the BASS_UNICODE flag is used, but otherwise you will need to make sure that any tags included in options are UTF-8 (not ISO-8859-1/etc).
