                                          const char *style);

Returns a list of settings for the profile `profile` that can usefully be exposed to a user. This usually means just bitrate/quality settings. This works by finding the name of the encoder element for the profile and retrieving a list specific to that encoder.

#### Parameters

profile | a GstEncodingProfile |
style | encoding style (NULL or "cbr" or "vbr") |

#### Returns

list of settings.

    char **
    rb_gst_encoding_profile_get_presets (GstEncodingProfile *profile);

#### Parameters

profile | profile to return presets for |

#### Returns

preset names.

Applies the preset `preset` to the audio encoding profile within `profile` .

#### Parameters

profile | a GstEncodingProfile |
preset | preset to apply |

### rb_gst_encoding_profile_get_encoder ()

    GstElement *
    rb_gst_encoding_profile_get_encoder (GstEncodingProfile *profile);

#### Parameters

profile | a GstEncodingProfile |

#### Returns

an encoder element instance.
