关于网页播放远程摄像头视频问题

通讯远程。WEBQQ有视频否？

有没有具体的activeX的解决方法啊，能不能贴一个看看谢谢啊

需要Activex支持吧
单纯的web我想没这么强大

我这边也正在做跟你类似的功能，我这边调用的是视频设备商的ActiveX，然后通过服务器端的IP，端口号，用户名和密码，才能调用那边的摄像头，看见视频画面，不过我要做成的是四画面形式。

我以前写的一个类你可以参考参考远程传输其实就是传图片  public class video

        {

        }        private void button1_Click(object sender, EventArgs e)

        {
            v = new video(pictureBox1.Handle, 250, 250, 429, 310);
            v.opVideo();

        }        private void button3_Click(object sender, EventArgs e)
        {
            v.CloVideo();
        }
    }
}

1、activeX方式，如果摄像头有相应api的话，采用这种方式，实现很简单。如果是普通摄像头，这中方式比较难实现。牵扯视频压缩、传输等还要考虑性能，很复杂。
2、fms（媒体服务器）方式，网上这方面的资料比较多。资料

谢谢大家帮忙，可是大家发的多数是 api CS的用法，这个我们的C++ 工程师已经写过dll给我们调用了，可是我这边需要在b/s系统的网页上调用，单纯的api是不行的，我在找一个网页使用的 activeX 控件
