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
- newtype VideoSink = VideoSink (ManagedPtr VideoSink)
- class (GObject o, IsDescendantOf VideoSink o) => IsVideoSink o
- toVideoSink :: (MonadIO m, IsVideoSink o) => o -> m VideoSink
- videoSinkCenterRect :: (HasCallStack, MonadIO m) => VideoRectangle -> VideoRectangle -> Bool -> m VideoRectangle
- constructVideoSinkShowPrerollFrame :: (IsVideoSink o, MonadIO m) => Bool -> m (GValueConstruct o)
- getVideoSinkShowPrerollFrame :: (MonadIO m, IsVideoSink o) => o -> m Bool
- setVideoSinkShowPrerollFrame :: (MonadIO m, IsVideoSink o) => o -> Bool -> m ()

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 ]
