解决方案

1. 统一JavaFX依赖版本

栈追踪显示javafx.media使用了19版本，而其他JavaFX组件（如javafx.fxml）是18.0.2版本，版本不一致会导致兼容性问题。修改Maven的pom.xml，确保所有JavaFX依赖版本统一为18.0.2：

<dependencies>
    <dependency>
        <groupId>org.openjfx</groupId>
        <artifactId>javafx-controls</artifactId>
        <version>18.0.2</version>
    </dependency>
    <dependency>
        <groupId>org.openjfx</groupId>
        <artifactId>javafx-fxml</artifactId>
        <version>18.0.2</version>
    </dependency>
    <dependency>
        <groupId>org.openjfx</groupId>
        <artifactId>javafx-media</artifactId>
        <version>18.0.2</version>
    </dependency>
</dependencies>

2. 修正FXML文档版本

打开FXML文件，将根元素的命名空间版本从19改为18.0.2，示例：

<?xml version="1.0" encoding="UTF-8"?>
<AnchorPane xmlns="http://javafx.com/javafx/18.0.2" xmlns:fx="http://javafx.com/fxml/1">
    <!-- FXML内容 -->
</AnchorPane>

3. 检查视频编码兼容性

JavaFX MediaPlayer仅支持H.264视频编码和AAC音频编码的MP4文件。如果视频编码不符合，使用FFmpeg转换：

ffmpeg -i 原视频.mp4 -c:v libx264 -c:a aac 转换后视频.mp4

4. 清理并重新构建项目

在IntelliJ中执行Maven -> Clean，再执行Maven -> Install，清除缓存的旧依赖文件，确保新配置生效。
