Enum gstreamer_video::AncillaryMetaField

#[non_exhaustive]
pub enum AncillaryMetaField {
    Progressive,
    InterlacedFirst,
    InterlacedSecond,
}

Location of a GstAncillaryMeta.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Progressive

Progressive or no field specified (default)

InterlacedFirst

Interlaced first field

InterlacedSecond

Interlaced second field
