Watching some streams I always cast the tab, then fullscreen the video and it optimises (making the original screen black and showing the full quality vid on my TV). This has always worked perfectly.
However the streamer must have changed the player they use and now all chrome will do is try to cast directly from the video rather than the tab (even though cast tab is selected in the chromecast options).
However, this results in a "clappr" message on the screen and nothing else. So I can watch the video on my desktop fine, but have no way of casting it because Google has decided it will cast directly from the video, rather than casting the tab.
This is infuriating, how can I override this/force it to cast the full tab? I have tried using my phone but the same result (and I don't want to cast from my phone anyway, it sucks for controlling the timebar on long videos).
Various iterations of this question have appeared over the years, some with changes to flags being suggested, but I can find no solution that works.
Why, in this instance, are Google trying to override what the user has instructed it to do (i.e. cast the tab!).
