Windows上的JavaFX MediaPlayer是否使用硬件加速来播放视频？

我问这个问题是因为在Mac和Linux上，我的应用程序播放视频非常流畅。此外，搜索也更加平滑。我们还使用mp4、h264视频编解码器

我有一台Windows笔记本电脑，硬件与我的Linux笔记本电脑完全相同，播放也可以，但它与我的Linux机器不同，而且肯定不如Mac电脑流畅

我设置了

prism.verbose=true

系统属性，因此每当应用程序启动时，我都会从prism获取信息

有没有一种方法可以确定硬件加速正在从输出中使用？Prism是否也是负责决定在视频播放期间是否使用硬件加速的组件

这是我的Linux计算机的输出：

您是否更新了视频卡的驱动程序？它应该支持D3D11，看起来你用的是9。在我得到Prism输出的Windows机器上，不，我想是的。但我确实有其他Windows机器执行相同的操作，我已经确保它们的驱动程序是最新的。这很奇怪。我发现windows具有卓越的图形性能。由于vlc在linux和windows上使用更少的cpu进行测试，我还没有检查media player。嗨@arjabbar，你知道如何检查硬件加速是否启用了吗？我也有类似的问题。谢谢。当我在开发这个应用程序时，我记得我确保启用了硬件加速。我记得开关它，以确保有一个不同的，事实上，有一个巨大的差异，在执行，特别是当通过视频寻找。
