Video exceeds window's size - JavaFX and FXML - javafx

Question

i've a trouble with JavaFX and FXML.
I've a simple FXML file structured in this way:
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.control.SplitPane?>
<?import javafx.scene.control.ToolBar?>
<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.layout.BorderPane?>
<?import javafx.scene.media.MediaView?>
<BorderPane maxHeight="1.7976931348623157E308" maxWidth="1.7976931348623157E308" minHeight="480.0" minWidth="720.0" xmlns="http://javafx.com/javafx/8.0.111" xmlns:fx="http://javafx.com/fxml/1" fx:controller="mediaplayer.MediaPlayerControllerSplit">
<center>
<SplitPane dividerPositions="0.5" maxHeight="1.7976931348623157E308" maxWidth="1.7976931348623157E308" minHeight="-Infinity" minWidth="-Infinity" BorderPane.alignment="CENTER">
<items>
<AnchorPane fx:id="mediaPaneL" style="-fx-background-color: green;">
<children>
<MediaView fx:id="mediaViewL" />
</children>
</AnchorPane>
<AnchorPane fx:id="mediaPaneR" style="-fx-background-color: red;">
<children>
<MediaView fx:id="mediaViewR" />
</children>
</AnchorPane>
</items>
</SplitPane>
</center>
<bottom>
<ToolBar minHeight="-Infinity" minWidth="-Infinity" style="-fx-background-color: black;" BorderPane.alignment="BOTTOM_CENTER">
<items>
<Button mnemonicParsing="false" onAction="#openVideo" text="Openfile" />
<Button mnemonicParsing="false" onAction="#playVideo" text=">" />
<Button mnemonicParsing="false" onAction="#pauseVideo" text="||" />
<Button mnemonicParsing="false" onAction="#stopVideo" text="stop" />
<Button mnemonicParsing="false" text="<<<" />
<Button mnemonicParsing="false" text="<<" />
<Button mnemonicParsing="false" text=">>" />
<Button mnemonicParsing="false" text=">>>" />
<Button mnemonicParsing="false" onAction="#exitVideo" text="EXIT" />
</items>
</ToolBar>
</bottom>
</BorderPane>
The controller will load 2 videos and show them in the relative 2 AnchorPanes inside the SplitView, as shown in the following image:

The video exceeds from width bounds of the Parent AnchorPane, how can i set them properly?
Thanks all.

Answer 1

I've solved this with the following line of codes in the Controller class:
mediaViewL.fitWidthProperty().bind(mediaPaneL.widthProperty());
The left (same for the right one) mediaView width has been fitted to his first Parent width (AnchorPaneL / AnchorPaneR).
