I don’t know why I still bother, but here goes anyways… please read the initial question/issue.
Using /popout has worked in all my desktop apps for the past 3 years. Using the embed is not an option because of its unexpected behavior.
I’m not preventing / blocking any clickthroughs, thus not breaking any rules. Again I’d ask to (re)read and try to understand the issue… If you don’t understand the real issue, stop trying to help as you’re not helping and get me someone that can help.
Things have changed (the way the video player is added to the page) and now break existing applications that have worked fine for years.
No offense, but please stop suggesting workarounds and the likes. This seems to be the default behavior here at Twitch instead of looking into the real issue.
Because it was brought up, I’ll elaborate on the clickthrough issue a bit. There’s no need for it to be the whole player. With the embed, the whole player becomes a redirect instead of the expected fullscreen (double click). The fullscreen behavior is what people expect, because it’s the standard behavior in every single media player on the planet, including for instance YouTube. And with the YouTube embed/API you can even customize it so it shows no YT branding at all.
