So I've been trying different things and still no luck, can't get the damn camera to connect and there is something strange happening...
First of all I too get that "Cannot connect to the address specified".
I've bought a TP-Link WN821N USB WiFi adapter that works and I'm connected to my Yi Action 4K (not sure if there are any gens like 1/2 old/new but its the newest one, not Yi Action, not Yi Action 4K+/Lite, just Yi Action 4K).
I'm running Windows 10 64 bit, CC version 0.6.10 downloaded from github, the camera firmware/version is 1.10.9 Build 2748r.
I'm able to display live view (with around 1,5 second of delay, low quality, lots of compression blocking/artifacting at low resolution and occasional signal dropout) in VLC by connecting to rtsp://192.168.42.1/live but the app no matter what I do won't connect to it properly, after displaying that message I get this: httpsA:A//imgur.com/a/d6MtN4X (delete two A between https : and //, for some reason forum blocks imgur links)
so it clearly is connected because it can read battery % and SD card usage but nothing else works, can't reeboot, format, do factory reset via the app, can't control, configure or use any functionality of the app.
Also I'm not sure if there is any point in making this work, I want at least full 1080p 60 fps or at least 1080/720 30 fps high bitrate/quality output, is it even possible or the live view will always look like crap (like the one from VLC)?
If so what good, cheap 1080p 60/30 fps webcam do you reccomend, should I check something from comapnies like Yi or I'm just best to go with Logitech one or something?
Also are there any other ways to get high quality live view from these via WiFi or is there finally a USB support? I tried doing it with the official App - streaming to Youtube, set it as private, then screen capture website in OBS and then stream to a proper website (in this example Facebook). It works but my network is too weak to support two live streams at the same time so the quality once the second stream starts goes down and is worse than live view in VLC. Also tried making my own RTMP server but couldn't get it to work (only have the NGINX display when typing in my IPv4 into a browser but the camera (the same technique, via official APP but this time in custom url instead of my Youtube streaming key/link I typed rtmp link with my IP but the camera couldn't connect this way).
