BigBox VLC Display Issue w/XAML Example

[throwingmuse]

The following BigBox View code snippet plays platform video files correctly when the video player is set to Windows Media Player. When the video player is set to VLC, the audio of the video may be heard, but nothing is displayed.

<Viewbox Grid.Row="0" Grid.Column="1" Grid.ColumnSpan="4" Grid.RowSpan="9" Stretch="UniformToFill" VerticalAlignment="Center" HorizontalAlignment="Center" Panel.ZIndex="2">
	<transitions:TransitionPresenter  TransitionSelector="{Binding ImageVideoTransitionSelector}" Content="{Binding ImageVideoView}" IsContentVideo="true" />
</Viewbox>

When the code snippet above is replaced with the following code, the video plays correctly when the video player is set to VLC.

<transitions:TransitionPresenter Grid.Column="1" Grid.Row="0" TransitionSelector="{Binding ImageVideoTransitionSelector}" Content="{Binding ImageVideoView}" IsContentVideo="true" Panel.ZIndex="2" />

Is there any known issue with the Viewbox object and its ability to span columns/rows while simultaneously stretching video content when using VLC? What else could be causing this display issue?

I need to be able to dynamically resize the video in the platform view across the designated grid.

I was able to get the video to resize and play in VLC by replacing Viewbox with StackPanel and removing the Stretch, VerticalAlignment, and HorizontalAlignment parameters:

<StackPanel Grid.Row="0" Grid.Column="1" Grid.ColumnSpan="4" Grid.RowSpan="9" Panel.ZIndex="2">
	<transitions:TransitionPresenter  TransitionSelector="{Binding ImageVideoTransitionSelector}" Content="{Binding ImageVideoView}" IsContentVideo="true" />
</StackPanel>

No amount of fiddling with Viewbox parameters would work with VLC.
