Question

我正在尝试使用JME3X-JFX播放flv文件，我使用demo class并可以通过http url方法播放their file。我也可以下载他们的flv并使用flv方法播放它。但我似乎无法播放我自己的flv文件（使用网站后下载，例如。keepvid（尝试了一对）从youtube视频网址（开放许可证）转换）。

它的声音类似于this question，只有黑屏显示，但对我来说，视频声音播放。我尝试使用RichFLV编辑元数据，使其与有效的演示视频的元数据类似。

另外，我尝试播放的视频至少是磁盘文件大小的一半（下载时）。

此外，大多数avis都不会为我播放，因为我得到一个不支持YCbCr_422，我认为可能是mp4的苹果版本。我不需要mp4但我需要至少一种类型才能工作。

回到FLV。我只是交换了一行：

final Media media = new Media("file:////Users/juliusskye/Desktop/FYPI/simplevoicehud/assets/Video/test.flv");

（这是他们要测试的视频重命名）到

final Media media = new Media("file:////Users/juliusskye/Desktop/FYPI/simplevoicehud/assets/Video/myvideo.flv");

，不同之处在于，工作版本（他们的视频）会调整大小，但我不会。

Answer 1

JavaFX库仅支持使用VP6编解码器编码的flv，其中很少有程序支持转换。

http://forums.macrumors.com/threads/vp6-codec-im-out-of-luck-arent-i.81314/ https://docs.oracle.com/javafx/2/api/javafx/scene/media/package-summary.html

我能够下载Sorenson Squeeze的试用版，允许在Mac上转换为VP6。 encoding.com似乎也提供转换即服务。

无法使用JME3-JFX播放电影文件
