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.
