GI.GstVideo.Objects.VideoFilter
Contents
Description
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.
Synopsis
- newtype VideoFilter = VideoFilter (ManagedPtr VideoFilter)
- class (GObject o, IsDescendantOf VideoFilter o) => IsVideoFilter o
- toVideoFilter :: (MonadIO m, IsVideoFilter o) => o -> m VideoFilter
- noVideoFilter :: Maybe VideoFilter

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

toVideoFilter :: (MonadIO m, IsVideoFilter o) => o -> m VideoFilter Source #
Cast to VideoFilter, for types for which this is known to be safe. For general casts, use castTo.
noVideoFilter :: Maybe VideoFilter Source #
A convenience alias for Nothing :: Maybe VideoFilter.
