看来你还不能做到这一点，请参阅这篇最近的文章。
然而，似乎有几个使用 JMF 至少能够捕获图像的示例。您也可以尝试 JNA。
It doesn't seem you can do it yet, see e.g. this recent post.
However, there seems to be several examples of using JMF to be able to at least capture an image. You might also try JNA.
距离提出问题已经差不多 7 年了，但仍然没有“原生”JavaFX 支持显示来自网络摄像头的流（据我所知）。
不过，我设法使用 OpenCV 库实现它并显示到
ImageView中。它可能效率低下，但 OpenCV 也为您提供了处理“流”的可能性。尽管人们可能只想显示流，而不是修改它。Almost 7 years later from when the question was asked and there still isn't 'native' JavaFX support for displaying a stream from a webcam (as far as I am aware).
However I managed to achieve it using the OpenCV library and displaying into an
ImageView. It's probably inefficient but OpenCV gives you the possibilities of processing the 'stream' too. Although all one might want to do is just display the stream, not modify it.
