Questions on Overlay Features in FlyLeaf Player

[fatihbahceci]

Hello. I have some questions about Overlay/MultiLayer features in FlyLeaf Player

1. How can I add a text overlay to a corner of the screen in FlyLeaf (eg: Rate, Time etc.)?
2. Can I overlay two videos on top of each other in FlyLeaf?
3. Similarly, can I add a logo or watermark over a video in FlyLeaf?"

Yes, please check the samples for that. Just keep in mind that if you use WinForms you might have issues with 'fake' transparency.

Hello again solved with the valuable information you provided. Thank you very much.

Here is a sample code
WPF

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="*" />
        <RowDefinition Height="100" />
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition />
        <ColumnDefinition />
        <ColumnDefinition Width="100" />
    </Grid.ColumnDefinitions>

    <TextBox  
        x:Name="tbFilePath"
        Grid.Row="1" 
        Grid.Column="0" 
        Grid.ColumnSpan="2" 
        HorizontalAlignment="Stretch"
        Padding="10,0,0,0"
        VerticalAlignment="Center"
        Text="cat.mp4"
        />
    <fl:FlyleafHost    
        Grid.Row="0"  
        Grid.Column="0"   
        Grid.ColumnSpan="3" 
        x:Name="host">
        <TextBlock    
            Grid.Row="0"   
            Grid.Column="0"   
            Grid.ColumnSpan="3"   
            Text="Text"   
            Width="300" Height="100"  
            FontSize="40"    
            Foreground="Yellow"    
            Background="Transparent"                
            x:Name="tbDraw"/>
    </fl:FlyleafHost>
    <Button Grid.Column="2" Grid.Row="1" Click="OpenFileCommand" Content="Play"/>
</Grid>
