## AI overview

A troubleshooting account of webcam streams pausing in OBS and browser-based applications. The article investigates virtual cameras on Windows, identifies LSVCam as a possible source of enumeration hangs, and describes a registry location where it appears.

## Source excerpt

I use my webcam constantly for streaming and I'm pretty familiar with all the internals and how the camera model on Windows works. I also use OBS extensively, so I regularly use the OBS virtual camera and flow everything through Open Broadcasting Studio. For my podcast, I use Zencastr which is a web-based app that talks to the webcam via the browser APIs. For YouTubes, I'll use Riverside or StreamYard, also webapps. I've done this reliably for the last several years without any trouble. Yesterday, I started seeing the most weird thing and it was absolutely perplexing and almost destroyed the day. I started seeing regular pauses in my webcam stream but only in two instances. The webcam would pause for 10-15 seconds every 90 or so seconds when access the Webcam in a browser I would see a long pause/hang in OBS when double clicking on my Video Source (Webcam) to view its properties Micah initially said USB but my usb bus and hubs have worked reliably for years. Thought something might have changed in my El Gato capture device, but that has also been rock solid for 1/2 a decade. Then I started exploring virtual cameras and looked in the windows camera dialog under settings for a list of all virtual cameras. Interestingly, virtual cameras don't get listed under Cameras in Settings in Windows: From what I can tell, there's no user interface to list out all of your cameras - virtual or otherwise - in windows. Here's a quick PowerShell script you can run to list out anything 'connected' that also includes the string "cam" in your local devices Get-CimInstance -Namespace root\cimv2 -ClassName Win32_PnPEntity | Where-Object { $_.Name -match 'Cam' } | Select-Object Name, Manufacturer, PNPDeviceID and my output Name Manufacturer PNPDeviceID ---- ------------ ----------- Cam Link 4K Microsoft USB\VID_0FD9&PID_0066&MI_00\7&3768531A&0&0000 Digital Audio Interface (2- Cam Link 4K) Microsoft SWD\MMDEVAPI\{0.0.1.00000000}.{AF1690B6-CA2A-4AD3-AAFD-8DDEBB83DD4A} Logitech StreamCam WinU
