Okay, so, I kinda-sorta had my streaming setup working pretty okay, with the big problem that I wasn’t able to get audio to come through digitally, and instead had to mix everything through the analog outs, going to the noisy input on the external USB audio interface. Not ideal. Also, the AVermedia drivers are unreliable and the app is crashy, and I didn’t have a good way of running the app at 1080p anyway (my laptop’s internal screen is only 768p and the HDMI dummy display I had was being unreliable about setting 1080p and there was no way to maximize the window without being able to click on it anyway, and on and on and on).
So, I went to Amazon and found a couple of devices (affiliate links) which simply convert HDMI to a standard webcam input – exactly what I wanted, because this could let OBS capture the audio and video as if it were a webcam. Which works really really well.
Unfortunately, neither device worked quite right; the one with the built-in splitter acts as a TV (for obvious reasons) and the HDMI passthrough thus uses a television colorspace, which doesn’t look right on the connected RGB-only DVI monitor. But audio works well.
The one without the splitter (using the external splitter) had all sorts of weird inconsistent colorspace behavior depending on which order things were plugged in, and I could never get audio to work at all.
Oh, and another thing I tried that almost worked was to plug my piano monitor into the second monitor output on the laptop, and run REcentral full-screen on that monitor. The resulting lag was a little annoying, but much worse was REcentral completely crapping out and going garbagey while I was trying to use it. Plus, I’m not a fan of any setup where I need the Windows machine to be on and fully-working just to use the external monitor. So that worked even worse than I’d expected.
So, for now I’m using the one with the built-in splitter and just dealing with weird colors on the monitor, and in the meantime I’ve ordered a cheap 24" HDTV that I can put up in place of the monitor. because of course I’m going to throw more money at this problem, because it’s irritating that I can’t get things to work quite right.
Oh, and meanwhile, I was also running into issues with macOS always detecting the capture device as preferring 720p, but fortunately it turns out that SwitchResX handles this. I was prepared to pay the $15 for it when I realized, wait, I already bought it back in 2005! And my license is still good for the current version! Yay! (Unfortunately this means my deadname is on the registration screen. I suppose I could ask them if I could get the name changed on the serial but I doubt it. If it really bothers me it’d probably be easier to just pay another $15. The software’s improved so much since then that it’d be worth it anyway.)
Anyway, the upshot of all this is that I can theoretically get my game streaming setup working again (I gave up on it because I could never get the AVerMedia to work reliably and it would usually crap out about 10 minutes into my stream), since the non-splitter one plus the external splitter is perfect for this.
And then I can sell the AVerMedia on eBay or something, I guess? Wow, their going price is extremely random, everywhere from $50 to $100. And I suppose I’d then have an extra monitor I should sell too.
Anyway, then I decided to try actually doing a music stream while a bit weedy and it wasn’t a fun time. But I was already frustrated from this tangle of tech. Why I keep on throwing myself into this never-ending morass I’ll never understand.
