Escaping the path in Windows command line doesn't work in my eyes. I want to extract frames from video files under Windows command line. This is the command: mplayer.exe -vf framestep=26 -framedrop -frames 12 -speed 100 "Y:\Testfolder \Testfolder 2\17.wmv" -vo "jpeg:outdir=\"Y:\Testfolder\Testfolder 2\17.wmv_thumbs\"":quality=100" The problem is the space in folder "Testfolder 2". The following error message occures: Could not parse arguments at the position indicated below: outdir="Y:\Testfolder\Testfolder ^ Anybody an idea?
