hello
can someone please help me with this?
i can find all the mp3s in a directory and its sub-directories with this:
find -name "*.mp3"
i can also ffmpeg a mp3 to m4a with this:
ffmpeg -i INPUT.mp3 -y -acodec libfaac -ab 192k OUTPUT.m4a
now, i would like to pipe all that find finds into ffmpeg.
thanks

Hello Guerrier!
Well that could end up being a little massy. Depending on spaces in
filenames. You might try something like:
for F in `find ./ -name "*.mp3"`; do
ffmpeg -i "$F" -y -acodec libfaac -ab 192k "$F".m4a;
done
You could use mmv later on to move the .mp3.m4a files or you can use some
shell magic, I've just seen this recently, I think it worked with percent
signs, but I can't remember the sybntax. If you know about sed or awk, you
could do something like:
O=`echo "$F" | sed -e "+s/\.mp3$/.m4a/g"`
Then your output filename will be $O in the script. I think this is better
than the awk idea. :-)
Warm regards
Julien

You could try something like this :
find . -name '*.mp3' | while read f
do
ffmpeg -i "$f" -y -acodec copy -ab 192k "${f%.mp3}.m4a"
done
That should properly handle filenames containing spaces.

I strong, STRONGLY *STRONGLY recommend *not* doing file manipulations
on audio files inside the shell. the proliferation of what once would
have been considered "wierd" names for files makes this extremely
"risky". it is very hard to prevent the shell from somehow getting
stuff wrong when the filenames can include ' or " or $ themselves.
use perl or python to do what you want, and thus avoid every issue
with shell globbing etc.

You're right Paul, of course. So here is the hopefully safe Perl
version :
#!/usr/bin/perl
use warnings;
use strict;
use File::Find;
use File::Copy;
sub wanted {
my $input = $File::Find::name;
return unless (-f $input);
return unless ($input =~ m/\.mp3$/);
my $output = $input;
$output =~ s/\.mp3$/.m4a/;
File::Copy::copy($input, "/tmp/i.$$");
`ffmpeg -i /tmp/i.$$ -y -acodec libfaac -ab 192k /tmp/o.$$`;
rename("/tmp/o.$$", $output);
unlink("/tmp/i.$$");
}
File::Find::find({wanted => \&wanted}, '.');
