The 10.4.39 x86 version seem to work nicely in the W10 x64 laptop!
After many tries I couldn't figure out what is wrong with the computer. It runs OBS, Zoom, etc, without a problem. I was just trying to get Splitcam x64 running by itself.
In the desktop computer, I7 processor, W10pro: I get image browsing (Firefox) http://192.168.8.2:8080/video I get image in SplitCam at the same address IP_Webcam says 1 connection in either case.
In the laptop with similar processor, W10home: I get image browsing (Firefox) http://192.168.8.2:8080/video, IP_Webcam says 1 connection No image in SplitCam at the same address and IP_Webcam says 0 connections
In the laptop I disabled the firewall but still no image.
If I enter just http://192.168.8.2:8080 in the desktop computer, I get camera control menu in the browser and dancing blue circles in SplitCam. I think it is normal. The same if I enter wrong address or IP Webcam server is not started.
I never get the dancing blue circles in the laptop.
I have the local laptop camera in laptop Splitcam.
