cant seem to cast videos from primevideo and various other streaming sites

[mm-salem]

Hello,
sorry to bother but i've been trying for quite some time now to stream videos from primevideo and other streaming sites to no avail
(sites that are not already on the whitelist and without using the duplicate screen function)

is it possible to do so and if so a tutorial would be welcome

sorry if asking too much

Sorry for the late response.

There are some instructions for how to use the extension in the FAQs section on the homepage:
https://hensm.github.io/fx_cast/#How_do_I_cast_something?

The whitelist comes with a few defaults, but you need to add other sites for them to be able to use cast functionality.

Some sites may not support casting on desktop even if they support it on mobile. Chrome has much better support for casting fullscreen video content via screen mirroring for things like Prime Video (though it's still not native cast support) that fx_cast isn't able to provide.

If there's a specific site that you think should work, submit a compatibility report here and I'll try to find out what's going wrong:
