### gst_gl_api_to_string ()

    gchar *
    gst_gl_api_to_string (GstGLAPI api);

#### Parameters

api | a GstGLAPI to stringify |

#### Returns

A space seperated string of the OpenGL api's enabled in `api`

### gst_gl_api_from_string ()

    GstGLAPI
    gst_gl_api_from_string (const gchar *api_s);

#### Parameters

api_s | a space seperated string of OpenGL apis |

#### Returns

The GstGLAPI represented by `api_s`

### gst_gl_platform_to_string ()

    gchar *
    gst_gl_platform_to_string (GstGLPlatform platform);

#### Parameters

platform | a GstGLPlatform to stringify |

#### Returns

A space seperated string of the OpenGL platforms enabled in `platform`

### gst_gl_platform_from_string ()

    GstGLPlatform
    gst_gl_platform_from_string (const gchar *platform_s);

#### Parameters

platform_s | a space seperated string of OpenGL platformss |

#### Returns

The GstGLPlatform represented by `platform_s`
