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?
