[SOLVED] Converting flac to ogg loses tagging info

Hantabaru · 2010-07-21 07:46:32

I have been converting flac files to ogg for my son's ogg player and have been running into the problem that the tags describing the album, artist and song name are not being transferred to the ogg file.

The flac file has the info at least when I check the file in EasyTag and it shows up in Banshee but when I convert it using Soundconverter to ogg the tags are marked "unknown" (Checked them in EasyTag).

I would like to being able to be able to batch convert the flac files to ogg with the song info being automatically transferred to the tags.

Any help would be much appreciated.

Maybe http://aur.archlinux.org/packages.php?ID=36627 ?
http://wiki.archlinux.org/index.php/Convert_Flac_to_Mp3 <- this one's for mp3s but it deals w/ tags, so have a look.

You're sure they're not MP3 tags? I have encountered a few FLACs (ripped with EAC, often) that didn't have Vorbis tags but MP3 tags.

If your FLACs have vorbis tags, oggenc will preserve the tags in the Ogg Vorbis file.

Thanks, didn't think to check the wiki...:(

Will have a look.

I'm not sure.

I ripped the songs directly from the cd using Grip and the default settings for flac encoding.

I then converted using Soundconverter.

Are there some flags I should be adding to flac encoding to get the correct tag format for vorbis?

What do you see when you run

metaflac --list

on one of your FLAC files? You should see the artist, album and title tags also.

Example:

METADATA block #2

As a convenience, the reference decoder knows how to skip ID3v1 and ID3v2 tags.

If your tags are in that format that's probably happening.

I'm usually using this script

#!/bin/bash
file=${1/.flac/}
qual=$2
echo "   File: $file.flac"
echo "Quality: $qual"
title=`metaflac --show-tag="title" "$file.flac" | sed "s/title=//"`
artist=`metaflac --show-tag="artist" "$file.flac" | sed "s/artist=//"`
album=`metaflac --show-tag="album" "$file.flac" | sed "s/album=//"`
date=`metaflac --show-tag="date" "$file.flac" | sed "s/date=//"`
genre=`metaflac --show-tag="genre" "$file.flac" | sed "s/genre=//"`
track=`metaflac --show-tag="tracknumber" "$file.flac" | sed "s/tracknumber=//"`

flac -c -d "$file.flac" | oggenc -t "$title" -a "$artist" -G "$genre" -l "$album" \
 -d "$date" -n "$track" -o $file.ogg -q $qual -

Then enter a directory

for i in *flac; do flac2ogg.sh "$i" QUALITY; done

Works for me. Of course the flacs should be properly tagged.

It looks like the comments/ogg tags are there.

As a side note...How would I add them on the command line if they weren't there?

Fantastic

Always more fun having a script to do it with

Will try this, but still want to figure out what is going wrong with the other method I have used.

The script works like a dream and encodes the tags correctly so that they show the artist, album and title when playing...thanks very much

A question about the script...How could I adjust it to put the encoded ogg files in another directory?

Would it be something to do with the -o switch of the oggenc line?

For example:

flac -c -d "$file.flac" | oggenc -t "$title" -a "$artist" -G "$genre" -l "$album" \
 -d "$date" -n "$track" -o /data/music/tmp/$file.ogg -q $qual -

Cheers

'-o' may mean output, so you can tweak it to your liking.

I have looked a the man page but as usual doesn't help until I have seen an example of its use.

I assume it is

--set-tag=field

              Add  a tag.  The field must comply with the Vorbis comment spec,
              of the form "NAME=VALUE".  If there is currently no  tag  block,
              one will be created.

which is the relevant bit, so does that mean it would be

metaflac --set-tag="album=Caught in a life" donkeyboy_sometimes.flac

If this is correct, where can I find a list of the NAMEs for each tag?

If this isn't correct, how should it look AND where can I find a list of the NAMEs for each tag?

Ok...tried the metaflac line using the tag "genre=pop" and that worked.

Still wondering if there is a list of the tag names anywhere?

IIRC there was one called "Christian Gangsta".

I've found this one: http://www.multimediasoft.com/amp3dj/he … 00003e.htm

Tried this adjustment to the -o switch and it works fine.

What would be really cool however would be if i can get it to automatically create an additional ./artist/album/ folder

I was thinking more like a list of the album, artist, title, genre, etc., but this is helpful too.

Hantabaru · 2010-07-21 19:50:41

About ready to mark this as solved.

The only thing really missing is why Soundconverter did not transfer the tags when converting flac to ogg?

.:B:. · 2010-07-21 19:51:16

You should be able to set whatever you want for the genre, that should not matter. I noticed however your Vorbis tags are lowercase variables, try uppercase ones and see how Soundconverter treats these. It would be silly, but you never know Soundconverter looks for uppercase variables.

Also, see if oggenc keeps the vorbis tags. If it does, then you can be positive the problem is with Soundconverter.

Also, if you're going to be converting FLAC to Ogg Vorbis, just use oggenc. Any script to convert FLAC to Ogg Vorbis is plain redundant. As I said the tags are preserved, I've been doing my conversion like that for years, litterally (nofi Foucault).

I usually use this script

oggenc -q6 *.flac
mv *.ogg /path/to/my/rockbox

(kinda)
Works!

Foucault · 2010-07-21 20:06:45

Damn, I totally forgot that oggenc can read FLAC. So much for all the hassle.

The script i was talking about was for batch converting lots of flac files and the one supplied by Foucault worked well.

The tags being lowercase was directly from the conversion of the wav files to flac by Grip, may try changing them to uppercase and seeing if soundconverter does it then, will see if I have time.

Happy now that I can do what I need to do now...marking this as solved

Appreciate all the help.
