Opencv_video320.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like opencv_video320.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. Wondershare Filmora) could share the same opencv_video320.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.
Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when opencv_video320.dll is attempted to be loaded either when Wondershare Filmora is starting up, or in some cases already running. Some of the most common opencv_video320.dll errors include:
- Access Violation at address - opencv_video320.dll.
- Opencv_video320.dll could not be found.
- Cannot find C:\Program Files\Wondershare\Wondershare Filmora\opencv_video320.dll.
- Cannot register opencv_video320.dll.
- Cannot start Wondershare Filmora. A required component is missing: opencv_video320.dll. Please install Wondershare Filmora again.
- Failed to load opencv_video320.dll.
- The application has failed to start because opencv_video320.dll was not found.
- The file opencv_video320.dll is missing or corrupt.
- This application failed to start because opencv_video320.dll was not found. Re-installing the application may fix this problem.
Your opencv_video320.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Wondershare Filmora), or deleted by a malware infection. Furthermore, opencv_video320.dll file corruption could be caused from a power outage when loading Wondershare Filmora, system crash while loading opencv_video320.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
