NAME
       struct_snd_enc_vorbis -

SYNOPSIS
       struct snd_enc_vorbis {
         __s32 quality;
         __u32 managed;
         __u32 max_bit_rate;
         __u32 min_bit_rate;
         __u32 downmix;
       };

MEMBERS
       quality
           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.

       managed
           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.

       max_bit_rate
           Enabled only if managed is TRUE

       min_bit_rate
           Enabled only if managed is TRUE

       downmix
           Boolean. Downmix input from stereo to mono (has no effect on non-stereo streams).
           Useful for lower-bitrate encoding.

DESCRIPTION
       These options were extracted from the OpenMAX IL spec and Gstreamer vorbisenc properties

       For best quality users should specify VBR mode and set quality levels.
