GI.GstVideo.Interfaces.VideoDirection
Description
The interface allows unified access to control flipping and rotation operations of video-sources or operators.
Since: 1.10

- constructVideoDirectionVideoDirection :: IsVideoDirection o => VideoOrientationMethod -> IO (GValueConstruct o)
- getVideoDirectionVideoDirection :: (MonadIO m, IsVideoDirection o) => o -> m VideoOrientationMethod
- setVideoDirectionVideoDirection :: (MonadIO m, IsVideoDirection o) => o -> VideoOrientationMethod -> m ()

noVideoDirection :: Maybe VideoDirection Source #
A convenience alias for Nothing :: Maybe VideoDirection.
class (GObject o, IsDescendantOf VideoDirection o) => IsVideoDirection o Source #
Type class for types which can be safely cast to VideoDirection, for instance with toVideoDirection.
Instances

toVideoDirection :: (MonadIO m, IsVideoDirection o) => o -> m VideoDirection Source #
Cast to VideoDirection, for types for which this is known to be safe. For general casts, use castTo.
Methods

Properties
videoDirection
No description available in the introspection data.
constructVideoDirectionVideoDirection :: IsVideoDirection o => VideoOrientationMethod -> IO (GValueConstruct o) Source #
Construct a GValueConstruct with valid value for the “video-direction” property. This is rarely needed directly, but it is used by new.
getVideoDirectionVideoDirection :: (MonadIO m, IsVideoDirection o) => o -> m VideoOrientationMethod Source #
Get the value of the “video-direction” property.
When overloading is enabled, this is equivalent to
get videoDirection #videoDirection
setVideoDirectionVideoDirection :: (MonadIO m, IsVideoDirection o) => o -> VideoOrientationMethod -> m () Source #
Set the value of the “video-direction” property.
When overloading is enabled, this is equivalent to
setvideoDirection [ #videoDirection:=value ]
