Scripting options (shell, applescript, etc) for batch conversions

[roboboticus]

Hi, I have a number of videos (.mpg) that I want to extract audio the from and save as mp3's. Is there a way I can automate this process, rather than dragging videos over to ffmpegx one at a time, waiting for the conversion to finish, then dragging the next one over? Applescript? Shell script? I'm on a mac.

Thanks!

Anybody out there?

Moving you to our mac section.

Nope. I have no idea.

You should be able to batch (extract & convert the audio to mp3) with mpegstreamclip

Give Quick Batcher a try.

you can always use python. it shouldn't be too difficult.

this is an old copy of ffmpeg compiled with mp3 support
runs fine on snow leopard but NOT tested it in lion or above.

download it and put it in /usr/local/bin or /bin
somewhere where the terminal can use it basically
get to those places by pressing command shift and g at the same time then typing the above

then this script will do what you want

copy and paste from below here

#! /bin/sh
echo drag your source folder in here
read sourcefolder
echo drag your destination folder in here
read destfolder
cd "$sourcefolder"
for i in *.mpg
do
name=`basename "$i"|rev|cut -c 5-|rev`
cat /dev/null|ffmp3 -i "$i" -vn -acodec mp3 -ab 128k "$destfolder"/"$name".mp3
done

for i in *.MPG
do
name=`basename "$i"|rev|cut -c 5-|rev`
cat /dev/null|ffmp3 -i "$i" -vn -acodec mp3 -ab 128k "$destfolder"/"$name".mp3
done

########
finish copying with the line above

copy all that into a text only file and save it as mpg2mp3.command on your desktop
then in the terminal type
chmod +x
then a space
then drag your .command file in to the terminal window

that makes it double clickable! hurrah!

when you run it, it will ask for a source folder, a destination folder and ffmpeg will spit out 128k stereo mp3 files of all the .mpg or .MPG files in your source folder

some messing about, but hopefully enough help so that you can modify it for other needs....
a bit of teaching to fish going on here.
