Please look into it..

Verified by the reference code below:

On iOS, a second call to getUserMedia() kills the display of a video stream obtained by an earlier call to getUserMedia(). The original stream displays fine until the subsequent getUserMedia() call, then goes black.

Note that this doesn't happen on Desktop Safari, only on iOS Safari in my tests.
