[MPlayer-users] mencoder cropping does not work?

[horst.schlonz at gmx.de]

hi,
i ripped an mpeg-file off an svcd with vcdxrip and it has very big black bars. 
i want to reencode this file with the black bars cut off.

here is what i did:

$ mplayer -vf cropdetect avseq01.mpg

[the movie plays without the black bars]

ok, now for the part where i believe my failure lies:

so, i thought my mencoder-command should reencode the file with the black bars 
cut off. but they are still there when i play the file with mplayer. also 
mencoder seems to change the container-format from mpeg to avi. where am i 
wrong?

i have debian sid with marillat-packages here.

thank you
