Big brain tip for watching the 5th Anniversary stream
Unless the deadbydaylight stream is an exception for some reason, midroll ads will play at some points on twitch which could ruin the viewing experience. So I'm not risking it.
So I recommend simply watching it on YouTube here: Dead by Daylight | 5th Anniversary Broadcast & Resident Evil Chapter Reveal - YouTube, with an adblocker installed. If you want the twitch chat experience as I do, simply use this link: Twitch for a popout of the deadbydaylight twitch chat.
