mediastreamer2 android,一起启动Linphone MediaStreamer2音频和视频流

仅使用mediastreamer2库我可以使用远程ip和端口开始音频调用，并调用audiostream.c各自的方法 .

然后我也需要开始视频通话 . 所以初始化videostream.c并使用其各自的方法并为其提供表面以呈现远程和本地相机馈送 . 我能够通过远程端口和ip成功启动视频流 .

但问题是我一起开始两个流 . 声音停止和视频流也停止 . 只有本地相机输入工作 .

所以我有一个神奇的方法，为我做这一切 . 如果我评论它的视频部分 . 音频通话工作正常，如果评论音频部分，视频通话工作正常 . 但是当我开始时 . 没有声音没有流媒体 . 但是我们成功启动了AudioStream并且VideoStream成功启动了日志 .

拥有linphone经验的人可以帮助确定正确的方法顺序吗？或者我们做错了什么这是我们的方法 .
