I have a n Apple tablet. I want to cast my device to my roku to watch Facebook live videos. Is there a way to do this for free? I tried looking for apps but they all want money to do the device casting which chocked be a free function. I can do it with my multi media already.
No, iOS doesn't support casting to a Roku. Android devices can, as can Windows 10 laptops. There have been apps that claim to support Roku casting from an iOS device, but I've never found anything that works.
Even for Android, not all can cast to a Roku. Many can only cast to a genuine Chromecast.
I used to have a Samsung S8, and it cast just fine with the correct app. Can't remember what that app was, though...
To expand a bit: Stock Android only works with Chromecast. Some manufacturers add extra drivers like MIracast to support more generic casting.
