how to do a freedb query?

kzar · 08-22-2004, 01:50 PM

Im trying to bodge a shell script to rip a cd to mp3. Im sick of trying to get other wrappers to do exactly what i want and also i wouldnt mind learning a bit. Problem is im having problems finding a way of getting freedb info about a cd.

I'm sure that some of these will disclose
(in their source ;}) how they did it...

looks like cd-discid and cddb-tool is the way to do it. this is going to take some head scratching though

im new to shell script

thanks for all the links. i was right about the head scratching

though. to get the freedb info it has to do all these steps...

get hostname and username (not hard)
cd-discid /dev/cdrom > sometempfile
cddb-tool query on that file > someothertempfile

some cleaver magic to get the genre of the album it found out of the someothertempfile but if it finds more than one entry just go for the first one and if it doesnt find any entrys for the cd throw an error or somthing

cddb-tool read using the genre we got earlier > anothertempfile

and hopefully then you will have information about the cd.

no clue how to do the bit which finds the genre from inside that text file though!

im going to bed for now , too tired to do anything this confusing

Can you post some demo-output?

Code:

#!/bin/bash

# Change these options
# Most arnt used yet ovbiously
cdrom="/dev/cdrom"
ripcommand="cdparanoia %track %out"
encodecommand="lame -S -q 2 -b 160 %in %out"
cdidcommand="cd-discid %cdrom"
freedbcommand="cddb-tool"
freedbserver="http://freedb.freedb.org/~cddb/cddb.cgi"

# Leave this alone
cddbuser=$(whoami)
cddbhost=$(hostname)

cd-discid $cdrom > /tmp/davidmp3script-cdid
cddb-tool query $freedbserver 5 $cddbuser $cddbhost `cat /tmp/davidmp3script-cdid` > /tmp/davidmp3script-query

This is what i have got so far, it puts the query into /tmp/davidmp3script-query but im stuck on the bit of getting the genre out of the file.

Right thought first step was knowing what i needed to do so i have got an example of each thing which could happen. Now to read about sed in that link you gave me

.

Multiple results

Code:

210 Found exact matches, list follows (until terminating `.')
misc b40d990c The Vines / Winning Days
newage b40d990c The Vines / Winning Days
.

Single result

Code:

200 rock 3506fb05 Kasabian /

No match

Code:

202 No match for disc ID 9b0a2b0b.

edit: i know what i need to do, get the code at the start, if its 210 read the first word of the next line as the genre, if its 200 read the second word of the first line as the genre or if its 202 throw a wobly.

/me high-fives kzar: "Excellent work mate!"

If you run into any problems, there's heaps of
really good bash-programmers here.

Thanks

. Here is the code so far, Ive pretty much finished the freedb stuff there but now i just have to write the whole cd ripping, mp3 encoding, mp3 taging and renaming bit . Wish me luck

.

Code:

#!/bin/bash

# Change these options
# Most arnt used yet ovbiously
cdrom="/dev/cdrom"
ripcommand="cdparanoia %track %out"
encodecommand="lame -S -q 2 -b 160 %in %out"
cdidcommand="cd-discid %cdrom"
freedbcommand="cddb-tool"
freedbserver="http://freedb.freedb.org/~cddb/cddb.cgi"

# Leave this alone
cddbuser=$(whoami)
cddbhost=$(hostname)

# Get the disk id
cd-discid $cdrom > /tmp/davidmp3script-cdid
# Get the query from freedb
cddb-tool query $freedbserver 5 $cddbuser $cddbhost `cat /tmp/davidmp3script-cdid` > /tmp/davidmp3script-query

# Get the genre from the query
responsecode=$(cat /tmp/davidmp3script-query | awk '{i++} i==1 {print ""$1""}')
case "$responsecode" in
                200)
                        genre=$(cat /tmp/davidmp3script-query | awk '{print $2}')
                ;;
                210)
                        genre=$(cat /tmp/davidmp3script-query | awk '{i++} i==2 {print ""$1""}')
                ;;
                202)
                        echo "No results"
                ;;
esac

# Get the read from freedb
cddb-tool read $freedbserver 5 $cddbuser $cddbhost $genre `cat /tmp/davidmp3script-cdid` > /tmp/davidmp3script-read

Bit stuck actualy, i have made a file which lists the audio tracks for ripping, it looks somthing like this.

Code:

Is there some kind of do until EOF loop ? i need to use these numbers but i cant think of how to do it.

kzar · 08-24-2004, 06:55 AM

Heres my attempt. Problem is putting the number variable just after the other one doesnt work.

Code:

for i in `cat /tmp/davidmp3script-tracks`;
do
temp=`awk '/TTITLE$i=/{print}' /tmp/davidmp3script-read`
track$i=`echo $temp | cut -d"=" -f2`
echo "$track$i"
done

Heres what it should do for the first track

Code:

temp=`awk '/TTITLE1=/{print}' /tmp/davidmp3script-read`
track1=`echo $temp | cut -d"=" -f2`
echo "$track1"

any ideas how i can achieve this?
