## Functions

### gst_vaapi_profile ()

    GstVaapiProfile
    gst_vaapi_profile (VAProfile profile);

Converts a VA profile into the corresponding GstVaapiProfile. If the profile cannot be represented by GstVaapiProfile, then zero is returned.

#### Parameters

profile | a VAProfile |

#### Returns

the GstVaapiProfile describing the `profile`

### gst_vaapi_profile_from_caps ()

    GstVaapiProfile
    gst_vaapi_profile_from_caps (const GstCaps *caps);

Converts `caps` into the corresponding GstVaapiProfile. If the profile cannot be represented by GstVaapiProfile, then zero is returned.

#### Parameters

caps | a GstCaps |

#### Returns

the GstVaapiProfile describing the `caps`

### gst_vaapi_profile_get_va_profile ()

    VAProfile
    gst_vaapi_profile_get_va_profile (GstVaapiProfile profile);

Converts a GstVaapiProfile into the corresponding VA profile. If no matching VA profile was found, -1 is returned and this error must be reported to be fixed.

#### Parameters

profile | a GstVaapiProfile |

#### Returns

the VA profile, or -1 if none was found

### gst_vaapi_profile_get_caps ()

    GstCaps *
    gst_vaapi_profile_get_caps (GstVaapiProfile profile);

Converts a GstVaapiProfile into the corresponding GstCaps. If no matching caps were found, `NULL` is returned.

#### Parameters

profile | a GstVaapiProfile |

#### Returns

the newly allocated GstCaps, or `NULL` if none was found

### gst_vaapi_profile_get_codec ()

    GstVaapiCodec
    gst_vaapi_profile_get_codec (GstVaapiProfile profile);

Extracts the GstVaapiCodec from `profile` .

#### Parameters

profile | a GstVaapiProfile |

#### Returns

the GstVaapiCodec from `profile`

### gst_vaapi_entrypoint ()

    GstVaapiEntrypoint
    gst_vaapi_entrypoint (VAEntrypoint entrypoint);

Converts a VA entry-point into the corresponding GstVaapiEntrypoint. If the entry-point cannot be represented by GstVaapiEntrypoint, then zero is returned.

#### Parameters

entrypoint | a VAEntrypoint |

#### Returns

the GstVaapiEntrypoint describing the `entrypoint`

### gst_vaapi_entrypoint_get_va_entrypoint ()

    VAEntrypoint
    gst_vaapi_entrypoint_get_va_entrypoint
                                   (GstVaapiEntrypoint entrypoint);

Converts a GstVaapiEntrypoint into the corresponding VA entry-point. If no matching VA entry-point was found, -1 is returned and this error must be reported to be fixed.

#### Parameters

entrypoint | a GstVaapiEntrypoint |

#### Returns

the VA entry-point, or -1 if none was found
