Sets up an Opus encoder on a channel, writing the output to a file.
HENCODE BASS_Encode_OPUS_StartFile(
DWORD handle,
char *options,
DWORD flags,
char *filename
);
| handle | The channel handle... a HSTREAM, HMUSIC, or HRECORD. |
| options | Encoder options... NULL = use defaults. The following OPUSENC style options are supported: --bitrate, --vbr, --cvbr, --hard-cbr, --comp / --complexity, --framesize, --expect-loss, --max-delay, --comment, --artist, --title, --album, --tracknumber, --date, --genre, --picture, --padding, --serial, --set-ctl-int. See the OPUSENC documentation for details on the aforementioned options and defaults. Also available is a "--no-reorder" option to disable reordering channels to the Opus specification's order, and a "--mapping-255" option that does the same but also sets channel mapping family 255 to prevent reordering by decoders (in theory). Anything else that is included will be ignored. |
| flags | The flags supported by BASS_Encode_StartUser may be used here, but the floating-point conversion flags are ignored. |
| filename | Output filename... NULL = no output file. |
| BASS_ERROR_HANDLE | handle is not valid. |
| BASS_ERROR_FORMAT | The channel's sample format is not supported by the encoder. |
| BASS_ERROR_ILLPARAM | options contains an invalid setting. |
| BASS_ERROR_FILEOPEN | A "--picture" option file could not be opened. |
| BASS_ERROR_FILEFORM | A "--picture" option file has an invalid format. It needs to be JPEG, PNG, or GIF. |
| BASS_ERROR_CREATE | The file could not be created. |
| BASS_ERROR_MEM | There is insufficient memory. |
| BASS_ERROR_UNKNOWN | Some other mystery problem! |
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).
