J2ME实现RTSP（只有在支持的手机才能用）

最近在研究J2ME实现RTSP协议，在索爱开发网站中看到一个类，但只能用于支持RTSP协议的手机，大部分手机需利用J2ME MMAPI实现，而对于自己实现的RTSP，虽然做了一些测试，调通了一点，但还没能真正运行，不知播放的效果如何，会不会像HTTP连接那么烂！

你去看lg 手机的标准吧。支持 vedio stream ，我不晓得这个是不是 rstp。

有没有 好的 rstp 的 服务器端推荐？

现在好几款机子支持，要做到通用，还是得写CODE，我所知道的像N73, N80, N91, K750i, V800, Z520i, K600, Z800i等都支持RTSP，但目前我手头没有支持的手机，我下载了Helix Server做测试用的，那个比较好目前不是很清楚！
