## Implemented Interfaces

GstVorbisEnc implements GstPreset and GstTagSetter.

## Description

This element encodes raw float audio into a Vorbis stream.

Vorbis is a royalty-free

audio codec maintained by the Xiph.org Foundation.

#### Example pipelines

    1
    gst-launch-1.0 -v audiotestsrc wave=sine num-buffers=100 ! audioconvert ! vorbisenc ! oggmux ! filesink location=sine.ogg

Encode a test sine signal to Ogg/Vorbis. Note that the resulting file will be really small because a sine signal compresses very well.

    1
    gst-launch-1.0 -v autoaudiosrc ! audioconvert ! vorbisenc ! oggmux ! filesink location=alsasrc.ogg

Record from a sound card and encode to Ogg/Vorbis.

## Functions

## Types and Values

### struct GstVorbisEnc

    struct GstVorbisEnc;

Opaque data structure.

## Property Details

### The `“bitrate”` property

      “bitrate”                  gint

Attempt to encode at a bitrate averaging this (in bps). This uses the bitrate management engine, and is not recommended for most users. Quality is a better alternative. (-1 == disabled).

Flags: Read / Write

Allowed values: [G_MAXULONG,250001]

Default value: -1

### The `“last-message”` property

      “last-message”             gchar *

The last status message.

Flags: Read

Default value: NULL

### The `“managed”` property

      “managed”                  gboolean

Enable bitrate management engine.

Flags: Read / Write

Default value: FALSE

### The `“max-bitrate”` property

      “max-bitrate”              gint

Specify a maximum bitrate (in bps). Useful for streaming applications. (-1 == disabled).

Flags: Read / Write

Allowed values: [G_MAXULONG,250001]

Default value: -1

### The `“min-bitrate”` property

      “min-bitrate”              gint

Specify a minimum bitrate (in bps). Useful for encoding for a fixed-size channel. (-1 == disabled).

Flags: Read / Write

Allowed values: [G_MAXULONG,250001]

Default value: -1

### The `“quality”` property

      “quality”                  gfloat

Specify quality instead of specifying a particular bitrate.

Flags: Read / Write

Allowed values: [-0.1,1]

Default value: 0.3
