I'm using v2.1.0. When I choose to output mp4 file, this error pops up. I don't know how to fix it.

Post your ffmpeg arguments here

It seems the configuration above is the arguments. And I have done nothing to change arguments.

If you want to try v2.2.0 [https://github.com/theTarkus/WebMCam/releases/tag/220]
In Options, press the Reset Args button and restart WebMCam and try to record something, and paste the process output again here
You're not running Windows N (-edition) by any chance, are you?
