Relatively easy isn't a term I would use around here, but yeah...you can do it simple enough. All selected in App. It's not a HD stream though. Old video:
You need 1000 subscribers to be able to livestream directly to youtube.
You can go through proxies (Restream) though, but it's not that simple to setup. Adds more latency.
With a mavic 1 it’s a simple thing. Once yr set to fly click the 3 dots top of the right hand corner of the DJI app. From that menu scroll down to live streaming platform. Select that then select which platform you want to use Click it then a screen comes up start live streaming Good luck
