(Solved!) Writing MP3 Tag Data

[ITSMERSH]

Hi.

I'm working on a program atm that can read MP3 Tag Info from .mp3 files using ffmpeg.

Code: Select all

"$FFMPEGBIN" -i "$FILE" > $TEMPDIR/tmp_id3ffmpeg$FILENAME 2>&1
FF_LENGTH="`grep -wm1 "Duration:" $TEMPDIR/tmp_id3ffmpeg$FILENAME | cut -d. -f1 | awk -F':' '{print $3":"$4}'`"
FF_BITRATE="`grep -wm1 "Audio:" $TEMPDIR/tmp_id3ffmpeg$FILENAME | cut -d: -f4 | awk -F' ' '{print $6}' | tr ',' ' '`"
FF_FORMAT="`grep -wm1 "Audio:" $TEMPDIR/tmp_id3ffmpeg$FILENAME | cut -d: -f4 | awk -F' ' '{print $1}' | tr ',' ' '`"
ID3_TITLE="`grep -wim1 "^    title" $TEMPDIR/tmp_id3ffmpeg$FILENAME | cut -d: -f2- | cut -d' ' -f2-`"
ID3_ARTIST="`grep -wim1 "^    artist" $TEMPDIR/tmp_id3ffmpeg$FILENAME | cut -d: -f2- | cut -d' ' -f2-`"
ID3_ALBUM="`grep -wim1 "^    album" $TEMPDIR/tmp_id3ffmpeg$FILENAME | cut -d: -f2- | cut -d' ' -f2-`"
ID3_DISC="`grep -wim1 "^    disc" $TEMPDIR/tmp_id3ffmpeg$FILENAME | cut -d: -f2- | cut -d' ' -f2-`"
ID3_YEAR="`grep -wim1 "^    year" $TEMPDIR/tmp_id3ffmpeg$FILENAME | cut -d: -f2- | cut -d' ' -f2-`"
ID3_DATE="`grep -wim1 "^    date" $TEMPDIR/tmp_id3ffmpeg$FILENAME | cut -d: -f2- | cut -d' ' -f2-`"
ID3_COMMENT="`grep -wim1 "^    comment" $TEMPDIR/tmp_id3ffmpeg$FILENAME | cut -d: -f2- | cut -d' ' -f2-`"
ID3_TRACK="`grep -wim1 "^    track" $TEMPDIR/tmp_id3ffmpeg$FILENAME | cut -d: -f2- | cut -d' ' -f2-`"
ID3_GENRE="`grep -wim1 "^    genre" $TEMPDIR/tmp_id3ffmpeg$FILENAME | cut -d: -f2- | cut -d' ' -f2-`"
ID3_ALBUMART="`grep -wm1 "Video:" $TEMPDIR/tmp_id3ffmpeg$FILENAME | cut -d: -f4 | awk -F' ' '{print $1}' | tr ',' ' '`"
echo "$FF_LENGTH" > $TEMPDIR/SongLength
[ -f $TEMPDIR/id3_info ] && rm -f $TEMPDIR/id3_info
echo -n "" > $TEMPDIR/id3_info
echo "FFMPEG: `basename "$FFMPEGBIN"`" > $TEMPDIR/id3_info
echo "File: $FILEBN" >> $TEMPDIR/id3_info
echo "Length: $FF_LENGTH" >> $TEMPDIR/id3_info
echo "Artist: $ID3_ARTIST" >> $TEMPDIR/id3_info
echo "Album: $ID3_ALBUM" >> $TEMPDIR/id3_info
echo "Title: $ID3_TITLE" >> $TEMPDIR/id3_info
echo "Track: $ID3_TRACK" >> $TEMPDIR/id3_info
echo "Genre: $ID3_GENRE" >> $TEMPDIR/id3_info
echo "Year: $ID3_YEAR" >> $TEMPDIR/id3_info
echo "Date: $ID3_DATE" >> $TEMPDIR/id3_info
echo "Comment: $ID3_COMMENT" >> $TEMPDIR/id3_info
echo "Bit Rate: $FF_BITRATE" >> $TEMPDIR/id3_info
echo "Format: $FF_FORMAT" >> $TEMPDIR/id3_info
echo "Album Art: $ID3_ALBUMART" >> $TEMPDIR/id3_info

Now I want to a dd a function to write such information into .mp3 files using ffmpeg.

Is that possible from within a shell script?

Any hints of how to achieve?

Thanks.

You can use ffmpeg too
https://unix.stackexchange.com/question ... tadata-tag

or id3tool

http://nekohako.xware.cx/id3tool/

or id3ren

https://github.com/sebcode/id3ren

I hope it will help you

[ITSMERSH]

Hi fabrice_035.

Thanks for the links.

Besides I discovered lame seems to have some options for this, I downloaded the source codes of id3tool and id3ren and compiled them successfully.

Then I just checked the PPM and discovered there is already compiled binaries of id3tool and id3ren in the Ubuntu repository.

However, I'm sure I will achieve my goal somehow by these tools.

Thanks again.

I have no idea how it does it, but Pcdripper allows to write some of the tag data. Perhaps you can learn something by inspecting the Pcdripper script or code or whatever it is called.

[ITSMERSH]

Hi Flash.

Thanks for the pcdripper 0.9.4 package.

I have 0.9.3 installed but both of them don't work, as both versions using

- apetag
- id3tag
- mp3info

for ID3 Tag Information.

None of them are installed in my Puppy, which makes pcdripper useless in my system.

---

However, I have successfully written my first ID3 tags into a MP3 file using my compiled version of id3ren. I've chosen to use this fresh compiled version as the binaries from Ubuntu Tahr repository are compiled from 2007 and they are smaller in size for some reason.

Thanks for all the help.

[Flash]

Are any of those things in this .pet? I got it along with Pcdripper at some point.

[ITSMERSH]

Thanks for the package Flash, but sorry: no!

I found at least

- id3tag
- mp3info

being available from the repos.

The apetag just wasn't found in the repos. Probably just needs to update the package manager repository files, but I'm too lazy to do so atm.

Thanks for the help again.

I think -at least for a first step- I can mark this as solved as my workaround using id3gen seems to work as expected. If anything goes wrong during time I can re-work this by using either id3tool, id3tag or probably mp3info (plus lame not to forget).

Your intention was to write information into .mp3 files using ffmpeg. Didn't this work?

[zigbert]

This is how pMusic is using ffmpeg for writing tags.

Code: Select all

ffmpeg -i "/root/Judas priest - Blood red skies.mp3"  -acodec copy -id3v2_version 3 -metadata title="Blood red skies" -metadata artist="Judas priest" -metadata album="Ram it Down" -metadata year="1993" -metadata track="6" -metadata comment="" -metadata genre="Heavy Metal" -y /root/Judas priest - Blood red skies_TAG.mp3

Your intention was to write information into .mp3 files using ffmpeg. Didn't this work?

Yes, this was my first thought of it, since I read out the information using ffmpeg. So I just assumed it MUST be done using ffmpeg also (didn't know of the other solutions possible).

After my opening post I discovered lame --help id3 options and found the post made by fabrice_035 mentioning id3ren and id3tool.

I decided to try these tools first as I don't have ffmpeg installed (my Art Studio originally came with avconf instead, which gives different results compared to the ffmpeg output). To read out the id3 tag information I'm using a temporarily sym-linked binary from outer file system (sub-dir on HD).

Since this is only a very small feature of the program I'm working on, I don't want to spend too much time on this issue. That's why I can live whith my id3ren workaround for now. Just calling it workaround since id3ren doesn't only write the id3 tags - it also renames the file. So, I needed to add a few lines to rename the file back to original.

[ITSMERSH]

Ok.

Tonight I stumbled over a case which makes it necessary to try some of the other possible solutions/options.

Once there was ID3 Tag information applied to an .mp3 file it can't be changed via id3ren.

Had to use kid3 to remove the ID3 Tags made during development.

[mikeb]

Not sure if useful but deadbeef can write tag information...there may be useful techniques in their sources though I suspect it actually rewrites the whole file.

Interesting thread.

[technosaurus]

I wrote some basic code to strip ID tags here
It doesn't do exactly what you are looking for but it may be a good starting point.

[ITSMERSH]

Thanks for the replies @mikeb & @technosaurus.

I rewrote my idren workaround using id3tool and it could change those ID3 tags immediately that I wrote to .mp3 files during testings.

BUT!

Unfortunately it can't change ID3 tags made on earlier files using kid3 (these files have data in both versions of ID3 tag data)!

I suspect both id3ren AND id3tool are writing the ID3 version 1 tags only...

Then I searched the PPM again for id3 and downloaded everything I found from Ubuntu repository.

I found id3v2 which seems to be pretty cool, as it has option to remove all ID3 tag data at once (id3v2 -D $FILE). So I just removing all tags by this command before writing new data to .mp3.

Now I need to find out what version of ID3 tags being written. Probably rewriting my script again for the use of id3v2 in general.

[Flash]

Isn't it great that there are so many standards to choose from?

[ITSMERSH]

At least it's some kind of fun, as I learn from every step I'm doing things in Puppy.

Just wondering someone doesn't consider it being a drug and to prohibit Puppy Linux?

[ITSMERSH]

Sometimes it's a hassle too!

I checked the output of id3ren and id3tool.
Both are writing id3v1 tags only.

The id3v2 writes both versions of tags and has option to choose which one to write (default seems to be id3v1 AND id3v2).

The next issue is on the Comment tag.

As soon as the Comment for id3v2 is written, I can't read out the comment tag via ffmpeg anymore. The kid3 proofed both of them are written, existing and displayed in kid3.

The id3v2 has also option to convert id3v1 tags to id3v2 tags.

When converting the Comment from id3v1 tag is NOT applied to the id3v2 tag!

Instead the kid3 shows a new tag under id3v2: --> id3v1 Comment <-- !

Hi RSH, Just mentioning, there's also eyed3
Display and manipulate id3-tags on the command-line
Description:

A command-line editor to add/edit/remove ID3-tags on mp3 files.
It supports version 1.0,1.1,2.3 and 2.4 of the ID3 standard.
Additionally it displays several information about the file
such as length and bitrate from an MP3 file.

It's python based, I've used it in the past, but didn't test recently.

[ITSMERSH]

Hi Fred.

Yes, eyed3 was under the packages I downloaded from Ubuntu repository.

After unpacking I found a Python script and removed the extracted directory immediately. I don't want to have hassle with Python added to this.

I recall the only two Python programs I ever got to work, has been:

- Openshot
- JACK Mixer

JACK Mixer just won't work from SFS. In all cases I'd to install JACK Mixer to get it running and working as expected - though, Openshot did work from SFS.

Python is still a mystery to me...

[ITSMERSH]

Ok,

after examining id3v2 a little more I found option to read out the tags from a file via id3v2. So I rewrote my script and am using now id3v2 exclusively to read AND write ID3 tags into the .mp3 files of my mix-downs/compositions.

Marked as solved now...

Code: Select all

function GetMP3ID3Info(){
	if [[ "$1" = *.mp3 ]]; then
