FFMpeg: Recording Video errors

Question

I try to record video (with audio!) in this way:

ffmpeg = "C:\bin\ffmpeg.exe"
cmd = '%s -r 15 -f vfwcap -i 0 c:/output2.mpg' % (ffmpeg)
os.system(cmd)

And I have error: "The filename, directory name, or volume label syntax is incorrect." I think that is sth with vfwcap, but I don't know how to fixed thi problem. Any ideas? Maby sth else is wrong?

Answer 1

isn't it just the small c in "c:/output.mpg" instead of "C:/output.mpg"?
