c++ - 调用应用程序 libjingle，用户自动从名册中删除。为什么？

Question

好的，尝试在 2 台装有 ubuntu 11.10 的笔记本电脑上运行 libjingle-0.6.14 中编译的“call”程序，

当我从第一台笔记本电脑登录，并从另一台笔记本电脑再次登录(使用不同的帐户)时.. 上线的用户会立即从花名册中删除，我没有人可以打电话...

这是输出..

从花名册中删除:smithtejesh@gmail.com/callAB04C4D8

smithtejesh@gmail.com 已从名册中删除..自动...这里可能出了什么问题？

Answer 1

调用“调用”示例的参数可能不完整。 libjingle 源附带的未经修改的示例不会从计算机硬件捕获视频/音频。它将播放包含音频/视频的 rtp 转储文件。源文件附带示例 rtp 转储文件，可用于向浏览器客户端播放音频/视频，或者可以“传输”到另一个“调用”示例客户端并在本地保存到第二个客户端上的 rtcp 转储文件。

使用调用示例程序的正确方法是(如果在 linux 上):

./call --videoinput ./test.rtpdump --voiceinput ./voice.rtpdump --videooutput ./vidoutput.rtpdump --voiceoutput ./voioutput.rtpdump

libjingle 谷歌代码网站上有几个问题讨论了这个问题，我目前正在努力寻找它们。如果我这样做，我将编辑这篇文章或添加带有链接的评论。
