Question

我正在研究javaFX媒体播放器，但是当我运行.AVI文件时，我得到了一个奇怪的错误。我的猜测是.avi不受支持，如果是这种情况我怎么能支持.avi？

我该如何解决这个问题：

Answer 1

JavaFX 2.2不播放avi电影。

您应该将avi电影转换为JavaFX能够理解的格式。可能最好的候选格式是MP4容器中的H.264编码视频。您可以使用ffmpeg等实用程序来执行此类转换。

JavaFX支持的媒体容器，编解码器和协议列表详见JavaFX 2.2 media javadoc。

此外，请确保目标计算机符合您要播放的媒体类型的system requirements。

尝试播放媒体时，还需要向媒体源提供正确的协议。从堆栈跟踪看起来您正在尝试从文件系统播放媒体，因此您需要在Media constructor javadoc中指定的媒体源字符串中包含file:协议。例如：

Media media = new Media("file:/c:/media/warandpeace.mp4");

为什么我不能在我的JavaFX MediaPlayer中播放.avi电影
