You've posted a couples times, and I have no idea what you're trying to do.
Yes, OBS can run offline...just record to your computer's SSD. But you're talking about using your phone to film your computer monitor? Why would you do that?
If you have good bandwidth on your phone, can't you just use your phone as a hotspot for your computer?
1. Phone hotspot is limited to either 5Mb/s in 5Mb/s out on Visible, or limited by a 10 Gigabit quantity limit and then slowed down to 2G. (a eupimism for mobile dial up. In other words sub 100kb/s speeds.). Plus my hot spot has to be used for Xbox Live and or Nintendo Online. I found a technicality to get around a one device at a time limit, but it's only 5 M in 5 M out for the whole network. My "Direct Cellphone" on the other hand is 40 Mb/s
BTW if someone can offer a better alternate to sub-minimal internet with low enough ping time for Xbox and either less draconian hot spot slowdown speeds than Visible, (5 Mb/s in/out is better than my monopoly DSL, Frontier, who offers a maximum of 1.6 M in, 400 k out, and regular cell phones fred the meter, or give you the dual up pile up) at potentially unlimited quantity, I'd like to hear it. Otherwise Visible is my only option for Xbox Gaming.
2 I was trying to use the second monitor output to feed a usb capture card and directly capture with it. Unfortunately, Android 10 (? Not sure, maybe it's Mac OBS) booby traps UVC capture cards, and there is no brand name "smart phone capture" software written for either IOS or Android. To be able to fully use the 40 M in, 20 M out, I need direct cell phone data. BTW IOS has no camera inputs available.
3. I may have found a way out of this bind. Yesterday I tried pointing a camera at my Macintosh screen, plugging in a 3.5 mm input for audio, and doing something known in the old days as "Kinascoping". Except instead of it being sent to film, it'scsemt through Twitch..
I am getting lots of problems of having it think it is required to fit the broadcast in the minimum bandwidth. But is there a way to tell Mac OBS that "bandwidth is no concern of this Mac's. My cellular phone is handling the data traffic." ?
I have 3D cameras stop filming because it seems a bandwidth limit is strictly enforced, and it cuts down features to fit.
BTW when I try mirror a second screen, the Mac decideds to switch screens. And my second screen feature DOES work UNTIL Mac OBS is loaded. As soon as it boots, second screen is lost.
And no, it's not a SLOBS for Android problem. I might get it to work if I plug in a UVC stereo camera and use Android SLOBS. I have to check.
But either Mac OBS or Something in OS 10.13.6 throws off the interaction. Once Mac OBS detects either an Android it a capture card, Mac OBS shuts the connection down.
