Chris,
Thank you for your suggestion. But I have gotten into a problem I get
errors and too many directories :(, Directories with spaces get
recreated and no ogg files are created :(

I have modified to above script. I don't get how the directory
structure is copied? I don't see a cp -r from_directory/ to
_directory/ then mplayer -ao ....
The option is not the same as I had it before. I guess if I can't get
it to work, I would need to go individually through each folder and
convert the mp3's with the original scripts.
I made another variation and it does not work either, this of course
before I try it on the machine where the actual songs that I want to
convert:
==================================
#!/bin/sh
#
# Notes:
#
# For each flac file in the current directory and its subdirectories,
# convert it to an mp3, importing the flac's tags. If the flac has
# Vorbis tags, use them. Otherwise look for id3v2 tags and use them
# if found. If the flac has no tags, log that fact and skip
# processing the file.
#
# This script traverses directory structures using a mechanism adapted
# from Steve Parker's traverse2.sh script.
#
# I assume that the commands ls, rm, sed, grep, pwd, wc and mkdir exist
# and can be called by those names. But let's make sure this system has
# the necessary third-party software installed, and find the binaries.
# Complain and exit if any one is not found.
MPLAYER=`which mplayer`
OGGENC=`which oggenc`
# Exit if we are missing anything:
if [ -z $MPLAYER ]; then
echo "mplayer not found! Exiting."
exit 1
fi
if [ -z $OGGENC ]; then
echo "oggenc not found! Exiting."
exit 1
fi
# Where to log errors?
LOGFILE=.ogg_err_log
# From Steve Parker, only slightly modified:
traverse()
{
# Traverse a directory
ls "$1" | while read i
do
if [ -d "$1/$i" ]; then
THISDIR=$1/$i
# Calling this as a subshell means that when the called
# function changes directory, it will not affect our
# current working directory
traverse "$1/$i" `expr $2 + 1`
else
FILE=$1/$i
# if [ $1 = "" ]; then
# echo "Please give an audio extension as argument."
# exit 1
# fi
for i in `ls | sed 's/ /_123BLANK_/g' | grep .mp3` ;
do {
mp3=$(echo $i | sed 's/_123BLANK_/ /g');
#fileman wmafile
wav=$(echo $1 | sed 's/.mp3/\.wav/g');
#filenname wavfile
ogg=$(echo $1 | sed 's/.mp3/\.ogg/g');
#filenname ogg
mplayer "$1" -ao pcm:file="$wav" && oggenc -b 128 "$wav"
"$ogg" && rm "$wav" && rm "$mp3";
}
done
fi
done
}
traverse . 0
=========================================
I don't need ID3TAGS/ARTIST/... all that information so I removed it.
I just want the script to batch convert the music files, whether
mp3/wma/m4a whatever they are and convert them to ogg vorbis like the
first script I had:
=========================================
#!/bin/bash
#
# Usage: convertoogg fileextention
#
if [ $1 = "" ];then
echo 'Please give a audio file extention as argument.'
exit 1
fi
for i in *.$1
do
if [ -f "$i" ]; then
rm -f "$i.wav"
mkfifo "$i.wav"
mplayer \
-quiet \
-vo null \
-vc dummy \
-af volume=0,resample=44100:0:1 \
-ao pcm:waveheader:file="$i.wav" "$i" &
dest=`echo "$i"|sed -e "s/$1$/ogg/"`
oggenc -b 128 "$i.wav" "$dest"
rm -f "$i.wav"
fi
done
=========================================
I hope that I can easily correct one of these variations. I would
actually prefer to pass a parameter like the script below and convert
wma/mp3/m4a to ogg and do it recursively then eliminate the wav files
and check to see that the oggs get created after they are created
delete the mp3 files.
Thanks for helping. I am experimenting and trying not to shoot myself
in the foot.
Regards,
Antonio
