class (GObject o, IsDescendantOf VideoSource o) => IsVideoSource o

Type class for types which can be safely cast to VideoSource, for instance with toVideoSource.

Instances

(GObject o, IsDescendantOf VideoSource o) => IsVideoSource o

Defined in GI.GES.Objects.VideoSource

toVideoSource :: (MonadIO m, IsVideoSource o) => o -> m VideoSource

Cast to VideoSource, for types for which this is known to be safe. For general casts, use castTo.

Arguments

:: (HasCallStack, MonadIO m, IsVideoSource a)

=> a

self: A VideoSource

-> m (Bool, Int32, Int32)

Returns: True if the object has a natural size, False otherwise.

Retrieves the natural size of the video stream. The natural size, is the size at which it will be displayed if no scaling is being applied.

NOTE: The sources take into account the potential video rotation applied by the videoflip element that is inside the source, effects applied on the clip which potentially also rotate the element are not taken into account.
