In windows the problem is still as before which is very wired. i checked
bellow command with different combination of single quote and double quote,
but always errors were there:

ffmpeg -i D:\test\1.mpg -vf "select='eq(pict_type\,I)' " -f image2

The problem is still there when i install ffmpeg on my ubuntu. when i runt
the command here , the ffmpeg error is that can not get -vf as a switch,
and does not accept it and when i removed the -vf, the error changes to,
can no recognized output format. The command in linux is:

ffmpeg -i test/1.mpg -vf select='eq(pict_type\,I)' -f image2
