No browsers other than Chrome work because no extension and tab 
capturing/DIAL/mDNS supports in other browsers.

I imagine anyone who is interested can easily detect the browser and if it is 
not chrome take one action and if it is chrome, then take advantage of 
__onGCastApiAvailable, so there is really no need to extend that.

but which api call should I use then to find out if the browser is capable of 
google cast/is the chrome browser? I think the condition "!window.chrome" is 
not very reliable and browser detection is considered bad practice.

If you do a Google search, you'll find your answer; that is a very common task 
for pages to figure out the agent type of the browser.
