我正在尝试制作一个简单的视频电话应用程序，所以我正在尝试制作一个程序来发送视频并使用Adobe的Cirrus接收视频。我虽然收到了流，但我遇到了麻烦。这是我正在使用的鳕鱼：

在getVideoReveiver()函数内部，我正在从writeText("flag")获取标志，然后在以下文本框中输出并输出：
NetStream.Play.Reset
NetStream.Play.Start
netStreamHandler的，但视频从未显示在接收视频元素中。
我正在运行这是同一台计算机的两个不同视频，并从一个流中获取nearID并将其粘贴到textInput theirID中。我不确定下一步该尝试什么？
答案 0 :(得分：0)
这是我为那些希望以此为例的人工作的脚本。您只需要一个Cirrus dev键。
