A video appeared inside a Hangouts chat stream and when I clicked it, it asked me which installed app I intend to use for playing that video.

I accidentally picked some casting app, but apparently (and surprisingly) the Use as default app was also checked, so whenever I click a video inside a Hangouts chat stream it tries to cast to a non-existing device and fails.

The system-wide video app is set to a normal video player app, but I can't find out how to set the default app for playing videos inside Hangouts.

Any idea how to reset it without uninstalling either app?

So far it is not Hangouts that need to be cleared in this case but the app which got registered as a default player.

Goto Settings -> Apps -> [Select the App that open when you play video inside Hangouts] -> Click Set as Default -> CLEAR DEFAULTS
