String containing custom OPUS options to send to the OpusEnc encoder.
Important note Starting from version 11 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 in the following situations:
During a recording session if the EncodeFormats.ForRecording property is set to ENCODING_FORMAT_OPUS and the EncodeFormats.OPUS.EncodeMode property is set to a value different from OPUS_ENCODE_CUSTOM.
During a CD ripping session if the EncodeFormats.ForCdRipping property is set to ENCODING_FORMAT_OPUS and the EncodeFormats.OPUS.EncodeMode property is set to a value different from OPUS_ENCODE_CUSTOM.
During an exporting session if the EncodeFormats.ForExporting property is set to ENCODING_FORMAT_OPUS and the EncodeFormats.OPUS.EncodeMode property is set to a value different from 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.
