Looking at the regular expression URL matching I believe is in play here:
You may get it to work by modifying the URL from:
https://static-s.bilibili.com/live-static/swf/LivePlayerEx_1.swf?room_id=10694&cid=10694&state=LIVE2
to:
https://static-s.bilibili.com/live-static/swf/LivePlayerEx_1.swf?room_id=10694&cid=10694&state=LIVE2&.swf
But really this is not something I’ve tried.
