[SOLVED] variable file input

lonesoac0 · 08-11-2011, 08:26 PM

hello all,

I have an issue with the command of:

Code:

mencoder -vf rotate=1 -o output.avi -oac pcm -ovc lavc *.MOV

It encodes from MOVs to AVIs just fine, but I can only do one at a time since output.avi is the only file name that my command knows to output to. I would like the capability to encode MOVs to AVIs in mass with one command.

Any ideas?

The only way to change the output filename of a hard-wired program is to get the source code and modify it. Not very practical for non-programmers. However, you could write a bash script (or python or perl) that would call mencoder for each filename and rename the output file to the original name with an avi extension (beyond my limited ability so ask about it in another thread here).

A Bash script would be fine for me.

Yo! I figured out what I wanted to do...it is some NASTY code though.

*********************
#!/bin/bash
for var in *
do mencoder -vf rotate=1 -o "$var.avi" -oac pcm -ovc lavc "$var"
done
*********************

I start with two files of IMG_0001.MOV and IMG_0002.MOV and end up with IMG_0001.MOV.avi, IMG_0001.MOV, IMG_0002.MOV.avi, IMG_0002.MOV

if anyone has any better code I would like to know!

hello all,

i have an update on this command. I finally figured it out.

Code:

#!/bin/bash
cd /DIR/DIR
set=$(ls -1 | grep '.MOV'')
for var in $set; do
        mencoder -vf rotate=1 -o $(echo $var | sed -e 's/.MOV/.avi/g') -oac pcm -ovc lavc "$var"
        rm "$var"
done

Note: That is a ONE and not an L in the ls -1 section!
