小编Kra*_*Z88的帖子

我正在尝试通过MediaStreamSource将Shoutcast流式传输到我的MediaElement.这是一些基础知识的代码.使用ReadData方法,我可以下载原始音频数据(MP3样本),我的问题是如何将流设置为MediaStreamSource.这样它就不起作用(它编译并且MediaFailed事件没有错误,但我听不到任何声音).也许我应该在我的自定义ShoutcastMediaStreamSource中实现所有这些？固定流没有问题,只是非固定.有人可以给我一些建议吗？

在WP7上,没有可能设置"useUnsafeHeaderParsing",因此我无法使用shoutcast元数据获取http标头 - 仅使用原始数据.在ShoutcastMediaStreamSource中,我实现了一些ManagedMediaHelpers的代码.

谢谢
