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
How about this one:
mencoder foo.mpeg \
-vf crop=720:352:0:64 \
-oac copy \
-ovc lavc \
-lavcopts vcodec=mpeg2video \
-o newfile.avi
Does mencoder peek at the outfile extension to determine container type?
This one is a little tricky, because mencoder will transcode
your file if you're not careful. So this part...
-ovc lavc -lavcopts vcodec=mpeg2video
...needs to change according to what your source material is.
I think the above might work for DVD material?
I'll try that.
