The Dali::Toolkit::VideoView is a control for video playback and display. It provides minimum functions for playback (play, pause, stop, forward, and backward). Some options, such as volume, can be controlled through the control properties. For the VideoView to work, a video plugin is needed. The Tizen 3.0 platform includes the required Dali video plugin.

Note The VideoView control does not use any privileges APIs on its own. However, if you use video files in a specific device storage, the application can require privileges to access the storage. For more information, see the Player API Reference (in mobile and wearable applications).

In this tutorial, the following subjects are covered:

VideoView events

The following table lists the basic signal provided by the Dali::Toolkit::VideoView class.

Table: Dali::Toolkit::VideoView input signals

Input signal Description
FinishedSignal() Emitted when a video playback is finished.

The VideoView class provides the FinishedSignal(), which is emitted when the video playback is finished. The related callback can support some basic actions.

void Create( Application& application )
  mView.FinishedSignal().Connect( this, &VideoViewController::OnFinished );

void OnFinished( VideoView& view )
  mFinished = true;

Creating a VideoView

The following basic example shows how to create a Dali::Toolkit::VideoView object:

class VideoViewController: public ConnectionTracker
    VideoViewController( Application& application )
      : mApplication( application )
      mApplication.InitSignal().Connect( this, &VideoViewController::Create );

    void Create( Application& application )
      // Set the handle
      mView = Toolkit::VideoView::New( "videofile.mp4" );
      Stage::GetCurrent().Add( mView );
      mView.SetParentOrigin( ParentOrigin::CENTER );
      mView.SetAnchorPoint( AnchorPoint::CENTER );
      mView.SetResizePolicy( ResizePolicy::USE_NATURAL_SIZE, Dimension::ALL_DIMENSIONS );
      mView.SetSize( WIDTH, HEIGHT );

    Application& mApplication;
    VideoView mView;
Note You can set the video file to be played in the VideoView::New() function, or by modifying VIDEO property with SetProperty( VideoView::Property::VIDEO, "videofile2.mp4" ).

VideoView Properties

You can modify the VideoView appearance and behavior through its properties.

The following table lists the available VideoView properties.

Table: VideoView properties

Property Type Description
VIDEO STRING or MAP Video file URL string. This property can also provide additional features, such as a custom shader, by Property::Map.
LOOPING BOOLEAN Whether the playback loops
MUTED BOOLEAN Whether the playback is muted
VOLUME MAP Playback volume. The Property::Map must get left and right volume scalar as a float type.
UNDERLAY BOOLEAN Video rendering by underlay

To change a property from its default value, use the SetProperty() function:

Property::Map oldMap;
Property::Value value = mView.GetProperty( VideoView::Property::VOLUME );
Value.Get( oldMap );

Property::Map newMap;
newMap.Insert( "volumeLeft", 1.0f );
newMap.Insert( "volumeRight", 0.5f );
mView.SetProperty( VideoView::Property::VOLUME, newMap );
