为什么 Javafx 本机图像不能与类 javafx.scene.media.MediaPlayer 一起使用？

问题描述

我使用 gluon 插件和 graalvm ce 21.0.0 在 win 10 上构建了一个原生镜像。如果我在没有 javafx.scene.media.MediaPlayer 的情况下构建应用程序，则客户端工作正常。如果我使用类 javafx.scene.media.MediaPlayer 我意识到文件夹 \target\client\x86_64-windows\gvm\tmp\deps 不包含 javafx-media 的 jar。但为什么？以及如何解决？当我运行客户端时，出现以下错误：

解决方法

正如 José Pereda 所写：Windows 尚不支持本机图像的媒体和 Web。我不知道。谢谢！
