Mencoding Mass

[meanburrito920]

Do you need to work recursively through the directory? or just one layer?

[Ryan450]

just one layer. keep it simple. But I'd like the output directory to be in the same folder as the .avi's

if

for i in `ls *.mpg`; do
mencoder -oac lavc -ovc lavc -of mpeg -mpegopts format=dvd -vf scale=720:480,harddup \
-srate 48000 -af lavcresample=48000 \
-lavcopts vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=5000:keyint=18:aspect=16/9:\
acodec=ac3:abitrate=192:threads=4 -ofps 30000/1001 -o ${i} ${i%.mpg}.avi;
done

as posted above works to do the encoding changed to start with .avi instead of .mpg,
then for what you want:

#! /bin/sh
for i in `ls *.avi`; do
mencoder -oac lavc -ovc lavc -of mpeg -mpegopts format=dvd -vf scale=720:480,harddup \
-srate 48000 -af lavcresample=48000 \
-lavcopts vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=5000:keyint=18:aspect=16/9:\
acodec=ac3:abitrate=192:threads=4 -ofps 30000/1001 -o ${i} ${i%}.mpg;
done
mkdir output
mv *.mpg output

(not sure this is 100% correct, but you should be able to make a file allong these lines executable and run it in a directory to convert the files and move them.)

BINGO! Thank you very much Sir .

That is exactly what I wanted. I knew the script would be simple, I've just not had enough time to re-learn my bash scripting. Something I'll have to brush up on very soon.

[meanburrito920]

in bash you could do something like:

#!/usr/bin/env bash

echo starting....

for f in ./*.avi; do

mencoder -oac lavc -ovc lavc -of mpeg -mpegopts format=dvd -vf scale=720:480,harddup \
-srate 48000 -af lavcresample=48000 \
-lavcopts vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=5000:keyint=18:aspect=16/9:\
acodec=ac3:abitrate=192:threads=4 -ofps 30000/1001 -o $f.mpg $f.avi ;
done;

echo finished...

Of course, you would need to strip the file extension off the file name, and maybe debug a bit, but it should work fine.

Ah, beaten to the punch!

[ghostdog74]

Note, this is untested and might break if files have spaces.

for i in `ls *.mpg`;

the above is what people call useless use of ls. use shell expansion instead

for i in *.mpg

hey these scripts work fine for file names without space !
but they dont work for file names with spaces,
for example
it wont work for "Scrubs S03E03 My White Whale [FuFu].avi"

is there any way to make it work for file names with space ?

is there any way to make it work for file names with space ?

Use quote marks, e.g. "$1" instead of $1.
