(~) AttrOpTag tag AttrSet => Constructible VideoOverlayCompositionMeta tag

Methods

new :: MonadIO m => (ManagedPtr VideoOverlayCompositionMeta -> VideoOverlayCompositionMeta) -> [AttrOp VideoOverlayCompositionMeta tag] -> m VideoOverlayCompositionMeta

newZeroVideoOverlayCompositionMeta :: MonadIO m => m VideoOverlayCompositionMeta

Construct a VideoOverlayCompositionMeta struct initialized to zero.

Properties

meta

parent Meta

getVideoOverlayCompositionMetaMeta :: MonadIO m => VideoOverlayCompositionMeta -> m Meta

Get the value of the “meta” field. When overloading is enabled, this is equivalent to

get videoOverlayCompositionMeta #meta

overlay

the attached VideoOverlayComposition

clearVideoOverlayCompositionMetaOverlay :: MonadIO m => VideoOverlayCompositionMeta -> m ()

Set the value of the “overlay” field to Nothing. When overloading is enabled, this is equivalent to

clear #overlay

getVideoOverlayCompositionMetaOverlay :: MonadIO m => VideoOverlayCompositionMeta -> m (Maybe VideoOverlayComposition)

Get the value of the “overlay” field. When overloading is enabled, this is equivalent to

get videoOverlayCompositionMeta #overlay

setVideoOverlayCompositionMetaOverlay :: MonadIO m => VideoOverlayCompositionMeta -> Ptr VideoOverlayComposition -> m ()

Set the value of the “overlay” field. When overloading is enabled, this is equivalent to

set videoOverlayCompositionMeta [ #overlay := value ]
