iOS linphone-iphone 没有视频只有音频
iOS linphone-iphone No video only audio
我在做一个可视对讲app，app需要带分机通话，分机是楼宇对讲分机，使用h264格式视频。我构建了linphone sdks，版本是3.8.2-28-g5d5808b。扩展程序是用别人搭建的，里面的内容我不知道，但是Android的app demo有视频。我的 iOS 应用编号 video.T_T
打电话时只有音频没有视频
我的应用调试内容：

您发送的第一个“200 Ok”（对于您收到的第一个 INVITE）包含：
m=video 0 RTP/AVP 0
a=inactive
这意味着您在接听电话时不接受视频。所以在这第一步中，视频仍然被信号禁用。
稍后，您通过重新邀请开始视频，但不幸的是，远程设备（对讲机）没有回复此重新邀请。您收到的不是 200 ok，而是临时的 100 Trying。由于第二次 re-INVITE 未完成，视频再次未通过信令建立。
最简单的解决方法当然是直接用视频回答第一个 INVITE。毫无疑问，这对于 linphone 的 API 应该是可行的！这可以解释为什么您的 Android 应用程序正确建立视频以及为什么您的 iOS 应用程序没有...
当然，对讲机应该回答第二个re-INVITE，这样也可以解决视频建立问题。
旁注：您的用户代理字符串似乎不合规...

我在做一个可视对讲app，app需要带分机通话，分机是楼宇对讲分机，使用h264格式视频。我构建了linphone sdks，版本是3.8.2-28-g5d5808b。扩展程序是用别人搭建的，里面的内容我不知道，但是Android的app demo有视频。我的 iOS 应用编号 video.T_T
打电话时只有音频没有视频

您发送的第一个“200 Ok”（对于您收到的第一个 INVITE）包含：
m=video 0 RTP/AVP 0
a=inactive
这意味着您在接听电话时不接受视频。所以在这第一步中，视频仍然被信号禁用。
稍后，您通过重新邀请开始视频，但不幸的是，远程设备（对讲机）没有回复此重新邀请。您收到的不是 200 ok，而是临时的 100 Trying。由于第二次 re-INVITE 未完成，视频再次未通过信令建立。
最简单的解决方法当然是直接用视频回答第一个 INVITE。毫无疑问，这对于 linphone 的 API 应该是可行的！这可以解释为什么您的 Android 应用程序正确建立视频以及为什么您的 iOS 应用程序没有...
当然，对讲机应该回答第二个re-INVITE，这样也可以解决视频建立问题。
旁注：您的用户代理字符串似乎不合规...
