[Semi-OT] Cropping a letterbox MPEG-2 file is easy enough...

[Ron Johnson <ron.l.johnson@cox.net>]

Hi,

But how do I save the output?

After reading the mplayer and ffmpeg man page and Googling, these 
are the three methods I tried, but none of them work.

$ mplayer foo.mpeg -vf crop=720:352:0:64 \
    -dumpstream -dumpfile bar.mpeg

$ mplayer foo.mpeg -vf crop=720:352:0:64 -o bar.mpeg

$ mencoder foo.mpeg -vf crop=720:352:0:64 \
    -ovc copy -oac copy -o bar.mpeg

$ ffmpeg -i foo.mpeg -vf crop=720:352:0:64 \
    -vcodec copy -acodec copy bar.mpeg


TIA

(Yes, Handbrake makes the job trivial, but no, I don't want to 
transcode the file, just "crop and save".  Disk is cheap and I want 
to retain DVD quality.)
