Video is not shown in case it is switched on/off on the fly

[sebazh]

Hi, thank you for this awesome package

I faced with the following issue: when i make call between two devices, i start call as audio call. Then any side can switch to video stream. If i try to make sendVideo(true) from callee side - it's not shown on caller side until caller also switches sendVideo to true. Is it intended behaviour?

Anything is ok if caller switches video sending to true first

Could you point me what might be wrong? Thanks
