libmpeg2_ff.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like libmpeg2_ff.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. Screen Recorder) could share the same libmpeg2_ff.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 libmpeg2_ff.dll is attempted to be loaded either when Screen Recorder is starting up, or in some cases already running. Some of the most common libmpeg2_ff.dll errors include:
- Access Violation at address - libmpeg2_ff.dll.
- libmpeg2_ff.dll could not be found.
- Cannot find C:\Program Files (x86)\Screen Recorder\Screen Recorder\filters\ffdshow\libmpeg2_ff.dll.
- Cannot register libmpeg2_ff.dll.
- Cannot start Screen Recorder. A required component is missing: libmpeg2_ff.dll. Please install Screen Recorder again.
- Failed to load libmpeg2_ff.dll.
- The application has failed to start because libmpeg2_ff.dll was not found.
- The file libmpeg2_ff.dll is missing or corrupt.
- This application failed to start because libmpeg2_ff.dll was not found. Re-installing the application may fix this problem.
Your libmpeg2_ff.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Screen Recorder), or deleted by a malware infection. Furthermore, libmpeg2_ff.dll file corruption could be caused from a power outage when loading Screen Recorder, system crash while loading libmpeg2_ff.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.
