Wow… So the issue really is - that the docs are outdated and confusing. Probably because they were converted from Chinese or something.
The two main things you need to do.
1 - get the cam on the same wifi as your phone. The trick here is - once you set up the wifi on the camera thru the doc… you have to hit the black bar on the bottom of the app on the phone - that doesn’t look like a button - to find the camera. It says something like LAN - but actually looks more like an error message.
2 – once the plugin is installed – and you choose to start the plugin – it opens up the web page that you need to enter the info in… BUT here’s the trick — you need to start by clicking the camera - - NOT clicking start stream. because for some reason the web page keeps any old stream key information in the page - - and the only way to over-ride it - - is to click the camera start key - - NOT thru the app on the phone.
IF you do these two things - you will save hours of misery.
