struct snd_enc_vorbis {

.PP
quality
.RS 4
Sets encoding quality to n, between \-1 (low) and 10 (high)\&. In the default mode of operation, the quality level is 3\&. Normal quality range is 0 \- 10\&.
.RE
.PP
managed
.RS 4
Boolean\&. Set bitrate management mode\&. This turns off the normal VBR encoding, but allows hard or soft bitrate constraints to be enforced by the encoder\&. This mode can be slower, and may also be lower quality\&. It is primarily useful for streaming\&.
.RE
.PP
max_bit_rate
.RS 4
Enabled only if managed is TRUE
.RE
.PP
min_bit_rate
.RS 4
Enabled only if managed is TRUE
.RE
.PP
downmix
.RS 4
Boolean\&. Downmix input from stereo to mono (has no effect on non\-stereo streams)\&. Useful for lower\-bitrate encoding\&.
.RE
.SH "DESCRIPTION"
.PP
These options were extracted from the OpenMAX IL spec and Gstreamer vorbisenc properties
.PP
For best quality users should specify VBR mode and set quality levels\&.
