Sets encoding quality used for OGG Vorbis format.
Normal quality range is 0 - 10. Quality -1 is also possible, but for most users may not be of acceptable quality. Fractional quality levels such as 2.5 are permitted.
This property is used only if the EncodeFormats.FormatToUse property is set to ENCODING_FORMAT_OGG and the EncodeFormats.OGG.EncodeMode property is set to OGG_ENCODE_QUALITY.
This property is the same as entering either the -q <quality> or --quality <quality> setting inside the Appendix B - OggEnc command line.
For further details about encoding in OGG Vorbis format refer to the OGG object section.
For further information about available encoding formats see the EncodeFormats object.
