Packit 06404a 
This is the primary function within libvorbisenc for setting up variable bitrate ("quality" based) modes.
Packit 06404a 
Before this function is called, the vorbis_info struct should be initialized by using vorbis_info_init() from the libvorbis API.  After encoding, vorbis_info_clear should be called.
