[MPlayer-users] -vo jpeg outdir problems with spaces in outdir

[HAM]

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?
