Dark video moving device from face up to vertical position about cordova-plugin-iosrtc

[ibc]

Sorry, no idea, it does not happen in my apps so it must be a bad usage. Please use the mailing list for questions and doubts about the plugin usage. And check this: https://github.com/eface2face/cordova-plugin-iosrtc/blob/master/docs/iosrtc.md#iosrtcrefreshvideos

I do more tests.
I try to stop refresh after 5s (from render start run) in PluginMediaStreamRenderer than nothing can modify native video from js/html. I think there is some problem in native side (maybe my problem but I can't find it).
I see that when the device is about 45 degrees there is something like a change orientation event (same fade-in animation of rotation device from portrait to landscape). For some frame on remote client the video appear upside down and dark and sometime the video is very slow.
I think there is something in RTCEAGLVideoView or in capture video.

I'm sorry, but I've never experimented that issue. If you get more data and a way to reproduce it feel free to comment here.

To reproduce it I try iOSAppRTC and there is the same problem...I'm doing more investigation

I fix the bug rebuilding webrtc library. It was was on avfoundtionvideocapturer.mm in updateOrientation function.
I simply put at row 286:

if(connection.videoOrientation!=orientation) { connection.videoOrientation = orientation; }

instead of:

connection.videoOrientation = orientation;

In this way the video is not re-initialized on every change of orientation but only if new orientation is different from current. I submit an issue to webrtc project but I don't know their time to approve it.
If you want you can add this fix to your patch to build webrtc for iOS for now.
