无法使用 JME3-JFX 播放电影文件

Question

我正在尝试使用 JME3X-JFX and i use the demo class and can play their file via the http url method. I can also download their flv and play it with the flv method. But i cant seem to play my own flv file (downloaded after using a site eg. keepvid（尝试过几次）从 youtube 视频 url（开放许可）转换来播放 flv 文件。

编辑元数据使其与有效的演示视频相似，这听起来有点类似于 this question, where only black screen shows, but for me, the videos sound plays. I have tried using RichFLV。

此外，我尝试播放的视频至少是其磁盘文件（下载后）文件大小的一半。

此外，大多数 avis 也不会为我播放，因为我不支持 YCbCr_422，我认为这可能是 mp4 的苹果版本。我不需要 mp4，但我至少需要一种类型才能工作。

回到FLV。我只是换行：

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），

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

不同的是，工作版本（他们的视频）会调整大小，但我的不会。

JavaFX库只支持用VP6编解码器编码的flv，支持转换的程序很少。

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，它允许在 mac 上转换为 VP6。 encoding.com 似乎也提供转换服务。
