There is no one-size-fits-all when it comes to configuration, so some reading is probably going to be required.
This page will tell you everything you need about config options for the Gdrive:

And this page will tell you everything you need about the mount command (as you will probably need a mounted drive for a media streaming app like Emby (I don't use that software myself, but I assume):
https://rclone.org/commands/rclone_mount/
In general though you can probably start off with using an all-default configutation. That should be perfectly fine for streaming. Worry about optional flags later on when everything is working.
All you really need to start is something like:
rclone mount MyGdrive: X:
Of course, this assumes that you have already configured your Gdrive as a remote. If you have not, then do that before anything else (you will find a detailed setp-by-step guide in the first link provided).
Later on, when you have a basic working setup, you may want to check out this thread for more advanced configuration (for Plex, but most of it will probably be applicable to Emby too).
