QuickTime Plug-in Safari

Hello ppl,

I currently have a MBPr running macOS Sierra. I have a home CCTV which can be accessed locally via my web browser (Safari) and it requires QuickTime Plugin. At first, it was saying that the plugin was missing. I went to /Library/Internet Plug-Ins and moved the quicktime plugin from the disabled folder to the internet plug-ins folder. The CCTV interface is no longer displaying the "missing plug-in" icon, but instead its stuck with the quicktime icon along with a progress bar - snapshot attached. Everything was working perfectly fine on Yosemite and El Capitan, I dont know if its an issue related to Sierra. Any help will be highly appreciated! P.S: - i can still access my CCTV via my iPhone or the DVR (which means that the issue is not related to my CCTV/DVR)
