Webcam randomly pausing in OBS, Discord, and websites - LSVCam and TikTok Studio

The author encountered a perplexing issue with their webcam, experiencing regular pauses during streaming and in OBS. The problem seemed to stem from a virtual camera called "LSVCam" that appeared in the Windows device list but was not recognized by some applications. This issue was traced back to TikTok Live Studio, which installs a virtual camera that may not be fully installed or hangs during enumeration. The author provided a PowerShell script to list all connected devices and a JavaScript code snippet to enumerate webcams, revealing the presence of "LSVCam." They discovered that "LSVCam" is linked to a DLL file in the TikTok Live Studio directory. This virtual camera can cause hangs and errors in various applications that rely on webcam access. The author identified the registry key associated with "LSVCam" and advised deleting it to resolve the issue. However, this is a temporary fix as the registry key will reappear upon running TikTok Live Studio. The author believes this issue is a regression in TikTok Live Studio's virtual camera implementation. The author shared this information to inform others experiencing similar webcam problems and hoped that the TikTok Studio development team would notice this post and address the issue. Deleting the registry key is a temporary workaround until a proper solution is provided by the developers.
