Introduction

This topic describes what is Video Splash Screen and how you can use it.

Video Splash Screen displays a short video while the application is loading and a static splash screen after the video is finished if the application is not loaded yet or no file for video splash screen was provided.

Separate video splash screen can be used for landscape and portrait oriented screens.

Video Splash Screen

1. A video is displayed and the application begins to load in the background.
2. The video terminates if a condition, specified by a ready-when event, is fulfilled.
3. The static splash screen is hidden on an application load.
4. The application is shown on the screen.

The video terminates after one of the below events and only those events. You have to choose one of them for your application:

• video-finished - the application will be shown if and only if the video has completed playing
• first paint - the application will be shown right after first paint becomes available
• complete- the application will be shown when it has finished loading
• custom - the application will be shown when window.screen.show() method is called

If during these events the video will be terminated but the application isn't fully loaded a static splash screen will appear for the remaining time.

The feature works with the following types of applications:

• web application
• native applications
• hybrid applications
• .NET applications

Video Splash Screen For Web Applications

This topic describes how to add video splash screen to a web application.

Prerequisites

1. In config.xml add tag:

<tizen:video_splash_screen ready_when="video-finished">
...
</tizen:video_splash_screen>

2.Inside this tag you can define splash screens depending on their orientations:

<tizen:vss_default ../>
<tizen:vss_landscape .../>
<tizen:vss_portrait .../>

Example Video Splash Screens Tags

Below is the example video splash screen declaration in config.xml of a web application.

    <tizen:video_splash_screen ready_when="complete">
        <tizen:vss_default video="res/test_video.mp4" background_image="background.png"
            background_color="#cbe0f2" image="Samsung.png" image_border="0px stretch"/>

Video Splash Screen For Native, Hybrid And .NET Applications

This topic describes how to add video splash screen to a native, hybrid and .NET application.

Prerequisites

1. In tizen-manifest.xml add tag:

<splash-screens>
...
</splash-screens>

2. Add communication between the application and video splash screen port.
   . A. Import aul_app_com_create from aul library to your application (the path is /usr/lib/libaul-extension.so.0). Example code in C#:

private const string AulLib = "/usr/lib/libaul-extension.so.0";
public delegate int app_com_cb(byte* endpoint, int result, ref bundle_t enevelope, IntPtr userdata);

[StructLayout(LayoutKind.Sequential)]
public struct aul_app_com_connection_s
{
	public byte* endpoint;
	public app_com_cb callback;
	public IntPtr user_data;
}

[StructLayout(LayoutKind.Sequential)]
public struct bundle_t
{
	public IntPtr kv_head;
}

[DllImport(AulLib, EntryPoint = "aul_app_com_create")]
public static extern int aul_app_com_create(byte* endpoint, IntPtr permission, IntPtr callback, IntPtr user_data, ref IntPtr connection);
...

.B. Create a message received callback. Example code in C#:

private DllImports.app_com_cb callback;
private IntPtr connection;

public unsafe int MessageReceived_Callback(byte* endpoint, int result, ref DllImports.bundle_t enevelope,
	IntPtr userdata)
{
	ShowMenu(true);
	return 0;
}
...

3. Create a message port for video splash screen communication before starting to load the application. The name of the port is created by pattern: "crosswalk.splashscreen.player." + appid, where appid is tv application's id. Example code in C#:

callback = MessageReceived_Callback;
DllImports.Create();
fixed (byte* p = ResourceLoader.GetBytes("crosswalk.splashscreen.player.JuvoPlayerOpenGLNative.Tizen.TV"))
{
	DllImports.aul_app_com_connection_s con = new DllImports.aul_app_com_connection_s();
	connection = Marshal.AllocHGlobal(Marshal.SizeOf(con));
	DllImports.aul_app_com_create(p, IntPtr.Zero, Marshal.GetFunctionPointerForDelegate(callback),
		IntPtr.Zero, ref connection);
}
...
