Fix iOS safari infinite loader and time parameter

I noticed that in version 4.+ in mobile safari, simultaneous playback of the screen share and a webcam did not work. In version 5.0.0, this bug was fixed (or I updated ios), but in some cases in safari, when opening the page, the loader remained even after loading all the resources. There was also the bug with the t parameter #80

Docs

I think it's related to safari webkit. Safari does not allow you to play more than one <video> with sound on the page. Here are links to explore: webkit bugs, webkit blog, possible solution

Added

• autoPlay attribute to screen share and webcam <video>
• pause() after screen share initialization to prevent immediately screen share playback

I'm not sure why we don't set the screenshare video muted. Maybe this could work as a solution as well. I still don't understand why we'd need to pause this media. It should be controled by the synchronizer... @antobinary do you think anyone could check on this?

Hey guys, I didn't quite get it, the safari you are talking about is the desktop one or the iphone's?

Because, I tested here and found the following issue: https://github.com/bigbluebutton/bbb-playback/issues/247 I searched here in the repo and didn't find any known issue regarding that!
