Catalog search terms OBS Studio
Recorded role: OBS Studio uses this process to package video and audio streams into container formats like MP4 and MKV using FFmpeg.
What you need to know
Feex's process catalog associates this filename with OBS Studio.
Check the running file before relying on the catalog identification.
- Does this name prove the file is safe?
- No. Verify the running file, its digital signature, publisher and behavior. The name alone is not enough.
A filename alone cannot establish that a running file is safe. Check the full executable path and digital signature, confirm the signer against the publisher, and investigate unexpected behavior with Windows Security or vendor guidance. A familiar folder or a valid signature alone is not a guarantee.

Recorded role and behavior
OBS Studio uses this process to package video and audio streams into container formats like MP4 and MKV using FFmpeg. It runs silently in the background while recording or streaming. Moderate CPU and disk activity are normal while writing files.
Inspect the running instance
In Windows PowerShell, this read-only query lists matching process IDs, creation times and executable paths on this PC.
Get-CimInstance -ClassName Win32_Process | Where-Object { $_.Name -eq 'obs-ffmpeg-mux.exe' } | Select-Object ProcessId, ParentProcessId, CreationDate, Name, ExecutablePath | Format-List
No result or an inaccessible path is inconclusive. Protected processes may restrict access, and process IDs can be reused. Keep personal paths local.
Use the file-identity guide to compare signatures and product metadata. A filename alone cannot establish safety.
Identify the actual running file
A filename alone cannot establish safety. Compare the actual path, product metadata and digital signature with the software you installed.
Investigate a problem safely
Compare repeated observations for the same PID while the symptom occurs. A single CPU peak or memory reading is not a diagnosis.
Save work and use the associated application controls to reproduce the symptom. Confirm the product identity before following its official update or repair guidance.
Evidence and corrections
The role and publisher are catalog associations. The references explain file checks, not the product association or your file's safety.
For corrections, send the article URL and public product documentation through Feex contact. Keep personal paths and credentials private.
