Previous pageReturn to chapter overviewNext page


[Visual Basic]

Public Property CustomString As string



public string CustomString {get; set;}



public: __property string get_CustomString();

public: __property void set_CustomString(string);




String containing custom OPUS options to send to the OpusEnc encoder.



Important note Starting from version 8 of the component, this property is ignored until the usage of default internal encoders is enabled: see the EnableInternalEncoders method for details about disabling internal encoders.



For advanced users, this string allows applying all of the possible OPUS encoding options available with OpusEnc. See Appendix E - OpusEnc command line for the complete set of available options.


This property is used only if the EncodeFormats.FormatToUse property is set to ENCODING_FORMAT_OPUS and the EncodeFormats.OPUS.EncodeMode property is set to OPUS_ENCODE_CUSTOM.


IMPORTANT NOTE: As you may know, the OpusEnc command line is as follows:

Usage: opusenc [options] input_file output_file.opus


Contents of the CustomString property are related to the [options] field only so you must omit entering the word opusenc and omit to specify the input_file. You should also omit the --raw option and any other options related to the raw input format which are already applied internally .


For further details about encoding in OPUS format refer to the EncodeOPUS class section.

For further information about available encoding formats see the EncodeFormatsMan class.
