GI.GstVideo.Objects.VideoSink

Description

Provides useful functions and a base class for video sinks.

GstVideoSink will configure the default base sink to drop frames that arrive later than 20ms as this is considered the default threshold for observing out-of-sync frames.

Synopsis

Exported types

newtype VideoSink Source #

Memory-managed wrapper type.

class (GObject o, IsDescendantOf VideoSink o) => IsVideoSink o Source #

Type class for types which can be safely cast to VideoSink, for instance with toVideoSink.

Instances

(GObject o, IsDescendantOf VideoSink o) => IsVideoSink o Source # 
Instance details

Defined in GI.GstVideo.Objects.VideoSink

toVideoSink :: (MonadIO m, IsVideoSink o) => o -> m VideoSink Source #

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

Arguments

:: (HasCallStack, MonadIO m) 
=> VideoRectangle

src: the VideoRectangle describing the source area

-> VideoRectangle

dst: the VideoRectangle describing the destination area

-> Bool

scaling: a Bool indicating if scaling should be applied or not

-> m VideoRectangle 

Deprecated: (Since version 1.20)Use videoCenterRect instead.

Properties

showPrerollFrame

Whether to show video frames during preroll. If set to False, video frames will only be rendered in PLAYING state.

constructVideoSinkShowPrerollFrame :: (IsVideoSink o, MonadIO m) => Bool -> m (GValueConstruct o) Source #

Construct a GValueConstruct with valid value for the “show-preroll-frame” property. This is rarely needed directly, but it is used by new.

getVideoSinkShowPrerollFrame :: (MonadIO m, IsVideoSink o) => o -> m Bool Source #

Get the value of the “show-preroll-frame” property. When overloading is enabled, this is equivalent to

get videoSink #showPrerollFrame

setVideoSinkShowPrerollFrame :: (MonadIO m, IsVideoSink o) => o -> Bool -> m () Source #

Set the value of the “show-preroll-frame” property. When overloading is enabled, this is equivalent to

set videoSink [ #showPrerollFrame := value ]
