                                          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.

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 ()
