GI.GstVideo.Objects.VideoFilter

Provides useful functions and a base class for video filters.

The videofilter will by default enable QoS on the parent GstBaseTransform to implement frame dropping.

class (GObject o, IsDescendantOf VideoFilter o) => IsVideoFilter o

Type class for types which can be safely cast to VideoFilter, for instance with toVideoFilter.

Instances

(GObject o, IsDescendantOf VideoFilter o) => IsVideoFilter o

toVideoFilter :: (MonadIO m, IsVideoFilter o) => o -> m VideoFilter

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