Enum gstreamer_video::VideoFieldOrder

#[non_exhaustive]
pub enum VideoFieldOrder {
    Unknown,
    TopFieldFirst,
    BottomFieldFirst,
}

Field order of interlaced content. This is only valid for interlace-mode=interleaved and not interlace-mode=mixed. In the case of mixed or GST_VIDEO_FIELD_ORDER_UNKOWN, the field order is signalled via buffer flags.

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.

Unknown

unknown field order for interlaced content. The actual field order is signalled via buffer flags.

TopFieldFirst

top field is first

BottomFieldFirst

bottom field is first
