Mp3 tag viewer with encoding/decoding purpose

I've got some idea about my mp3 collection: there is many files with cyrillic tags in different encodings, and furthermore each file may have tags in different encoding ( it is ugly mess ). So i can not use programs like EasyTag or tag2utf etc.
What i can is to print every field in every tag in every file, list it in front of my eyes, and if i catch some buggy text, select appropriate encoding for only this filed. Also i can use chardet to pre-encode stuff.
I've wrote simple script in python2 that use pyqt, tagpy and chardet. It has sortable table and editable fields and some other stuff, so you can open some files ( many many file like in my ugly collection ), unhurriedly scaning it with eyes for bugy text and correct what you find wrong.
And what is the question? Is anyone in there need it?
ps sory for my english.

Mp3 tag viewer with text encoding/decoding purpose

I'm want suggest some idea:
Let assume that we have many mp3 files with cyrillic or some else non ascii tags in different encodings. And let assume that each file may have several encodings (eg cp1251 for album and utf-8 for title). Programs like EasyTag is not convenient for such case.
So idea: draw all tags for many files in simple table and decode what you want on the fly, independently for field, not whole file.
ps I'm not like a programmer or so, so i dont know should i start new project or not. Here on my hands some very first script in python, pyqt, tagpy, chardet.

Because of zero attention for such idea in this topic and because i finally remove my messed up collection of music i decide to drop this git.
PS. this program is just little sample end if no one is reply for idea and if it even doesn't need for me anymore creating is impossible. that's all : )

Encode/Decode string from unix shell

Hi,
I am not sure I'm addressing my question properly, but simply I have a stream where I send commands to a shell and when these commands come back from the input stream they don't mean anything as shown below:

I am using the utf-8 for encoding...do I need to decode it and how?
Here is part of my code:
OutputStreamWriter writer = new OutputStreamWriter(sess.getStdin(), "utf-8");
writer.write("my string");
writer.flush();
class StreamGobbler implements Runnable {
        InputStream is;
        OutputStream oi;
        String type;
        ResultBean resultBean;
        StreamGobbler(InputStream is, String type, ResultBean returnValue) {
            this.is = is;
            this.type = type;
            this.resultBean = returnValue;
        @Override
        public void run() {
            try {
                InputStreamReader isr = new InputStreamReader(is, "UTF-8");
                BufferedReader br = new BufferedReader(isr);
                String line = null;
                while ((line = br.readLine()) != null) {
                    //System.out.println("TYPE[" + type + "] COMES FROM STD_OUT THREAD: " + line);
                    this.resultBean.addResultLine(line);
                    this.resultBean.addMessage(line);
            } catch (IOException ioe) {
                System.out.println("IOE Exception in StreamGobbler");
                ioe.printStackTrace();
    }Thanks in advance, i never dealt with encoding/decoding text.

I am pretty sure it is an encoding issue, I'm not convinced because ^H is the ASCII backspace character. Maybe not as I originally thought just some padding but it looks like some form of formatting done the old fashioned way using control characters.
because if I also send this output in an email format and the email renders it a bit differently, then if I copy and paste the text to html page and render it on the screen it look as it is suppose to be.It's definitely not HTML so this does not seem logical.

Here are the ios commands I am issuing:

Adding mp3s for playlist mixes that don't clutter Artist & Album views with single songs?

Sometimes I like to just grab various mp3s on my computer & stick them in a directory for a quick mix, for a drive or get-together or whatnot. Problem is, when I add the directory to iTunes it populates my Album & Artist views with these single songs. When the playlist is 60+ songs (many of which are single tracks not duplicated in existing iTunes albums or artists) the default browsing views get really cluttered & I'm not looking to find these when I'm browsing the general collection - just want them for that particular playlist.
Is there a way to add a directory of mp3s while telling iTunes to ignore sorting them by Album or Artist or displaying them anywhere but the playlist? I've tried "Part of a Compilation" but it doesn't seem to be always effective & at that point I already have to tediously sort through to find all the stragglers. Again, with a large playlist this can take a ton of time.
I'm guessing (hoping) there's a quick fix for this, any suggestions?

No, what you see is what you get... If you want to add a track to an iTunes playlist it gets added to the library proper, and the details show up where appropriate.
If you're not bothered about preserving the original details Album=My Playlist Name, Album Artist=Various Artists, and Part of a Compilation=Yes will minimise the impact, provided you use the options under View > Column Browser to Group Compilations and Use Album Artists
See Grouping tracks into albums for general tips.

Edit (modify or change) MP3 tag with iTunes

Hi All!
Someone knows how can i change, modify or edit the mp3 tag with iTunes 6? Is it possible?
If it isn't possible, do you know some plug-in for iTunes (or external program) that allow me to change mp3 tag of a file(s)?
tnx a lot

right-click on the entry in iTunes and select "Get Info". The "Summary" tab tells you a little about the file, while the other tabs (Info, Options, etc.) let you edit ID3 tags supported and used by iTunes.

How to find out what text encoding has been used in mp3 tag

Hello
I have some foreign songs that I am importing into itunes. When a song called "04.公路塵埃北合起." gets imported, it comes up in itunes as "04.§Ω∏Ù π–ÆJ •¶X∞"
Now I don't know a lot about different text encodings, but from what I've read on the forums is that the problem is that the tags that are encoded on the srcfiles are not unicode. I have tried the java application "UnicodeRewriter" recommended elsewhere in the forums, but both the commone Chinese ecodings, viz Big5 GBK etc.
Is there a way to cut a world from (eg a chinese glyph) and somehow find out what text encouding has been used?

Sorry, that question wasn't very well phrased. I'll try it again.

I have tried the java application "UnicodeRewriter" recommended elsewhere in the forums, but whatever I sent the source encoding to, eg Big5, GBK, or one of about 9 others, I just get different types of garbage coming through.
Is there a way I could take the original glyph in the file name (which shows up correctly on my desktop) and paste it into some sort of table. That table will then show me how that glyph will look in all different encodings without the correct conversion. So if I can match my "公" to my "§" I'll be able to see what the src encoding is.
I know this is a longshot, but any help appreciated.
Sorry for the rather rubbish explanation earlier.

ITunes on new computer not reading MP3 tags

I have transferred my library of MP3 that were ripped from CD from my old computer to my new computer, and many of the files do not show the album name or artwork, etc. in iTunes. If I look at file properties in Windows, however, all the information is present for the MP3 - album, artist, etc. I have found that there is a field called "Encoded by" and is says "iTunes 11.0.2.26", or some other is an older version of iTunes. If this iTunes version is older than the latest version of iTunes on my new computer, then iTunes does not read the MP3 tags correctly. If I manually change that iTunes version in Windows to the latest iTunes, then that file is fixed!!!
My question is, what is the fastest way to make this change for all the files that are showing old info in the "encoded by" field? The files are all buried in various artis->album folders in the music folder, and I can't see any way to change this field from iTunes, I can only do it from windows explorer. If I could do it in iTunes it would be fast because I could group all the bad files together, select them all, and change them in one step.
Please help! I am close to fixing it!

Are you using the latest downloaded version of iTunes from Apple.com, instead of a version that came on disc with the iPod? According to this article, Windows Vista 64-bit required iTunes 7.6 or later
http://support.apple.com/kb/HT1426
Also, make sure you got the version of iTunes 8 for Windows Vista 64-bit

Lightweight library for reading and writing mp3-tags

Hi,
I'm currently evaluating libraries for reading and writing mp3-tags. All the projects I found so far where not maintained for a couple of years.
My question:
Is there currently a library, which one could call standard for this purpose
Cheers
Jonny

All the projects I found so far where not maintained for a couple of years.It may either be dead, or it may be so finished and free of bugs that no maintenance is needed anymore.
If you're occurring problems with it and if it is open source you can always consider taking a fork for own development.

Audio/Video encode & decoding

I am very new to mac environment,
and have a background as a linux developer. I worked mostly with avcodec and avformat api's (from ffmpeg project) to manipulate media. I could reach media devices/streams using oss, alsa, v4l or v4l2 interfaces/drivers and encode/decode them with avcodec API. Now I switched to mac and I want to get audio/video frames from input devices and encode/decode them as I want. I already took a look at QTkit and QT related topics but there is no codec variation and also no control of frames which has taken from input device/file. There is no flexibilty with almost just one way to encode media (h264 and AAC, with predefined bitrates). I am using snow leopard with Xcode 4 so AVfoundations is avaliable just for IOS env. and not for Mac environment.
I can not find any detailed media encoding/decoding document or usable(flexible) framework in mac developer central. Please help me to find or give me some advice about mac environment.
Thanks in advance .

First of all thank you xnav. But I already searched for AVFoundations and related sample sources. I do not want to change my operating system and I do not want to believe that MacOS has not got a framework embracing the media related functions at all before Lion. As I mentioned in the text above I am using snow leopard.
By the way I want to reach full control over media streams/frames and codec parameters. I want to be able to decode media stream/frame if it is encoded (for example: a web cam streaming jpeg captures using hw codec) I want to decode and resize it, maybe view it in a frame and encode it again and store it in a file or directly stream over rtsp. Is it possible ? Does't Apple have such a framework which I can find in open source environment easily (for example: ffmpeg - avcodec - avformat - avdevice). Device/driver level tools and codecs can be inside different frameworks but there must be some tools for it.

View with Bind Variable and ADF table

Hi all,
Please note what i have noticed. I created a view with a bind parameter, overriden the prepareSession of my Application Module to set the bind parameter and execute the query. I then created a simple jsf page and included the view as an adf read-only table. When i run the page, the prepareSession is called, sets the bind parameter, however the selected record of the table is always the second record (Not the first record).
This behaviour can be reproduced with the HR schema. Please follow the below instructions for reproducing the problem.
1. Create a Fusion Web Application (ADF).
2. Create business components from tables.
3. Create a new connection with the HR schema.
4. Import the Departments table as an entity and then click finish.
5. Create a view based on the Departments entity.
6. Modify the Query to include a where clause (where DDepartmentsEO.DEPARTMENT_NAME LIKE :BindParam)
7. Provide an order by clause (DepartmentsEO.DEPARTMENT_ID DESC)
8. Creata a bind variable named "BindParam" of type string.
9. Create an Application Module and include the view object.
10. Open the Application Module Class and override the prepareSession method
11. include the following code after super.prepareSession(session):
ViewObject myView = this.getDepartments1();
myView.setNamedWhereClauseParam("BindParam", "%");
myView.executeQuery();
12. Create a jsf page
13. Drag the view object on the page as an adf read-only table, selecting the Row Selection, Sorting and Filtering
14. Run the page.
You will see that instead of the first record being selected, the second record in the table is selected.
Can anyone please help me?
Thank you

First of all i would like to thank you for replying to my thread.
Secondly, i would like to inform you that the example that i have provided is just for REPRODUCTION purposes.
The real scenario has to do with setting the where clause with the authenticated user so that the view will query for data only associated with the authenticated user.
The only way to overcome this behaviour is to include a view action (namedWhereClause in the page definition)
However, this is not how i want to implement this. This was working properly in 10g

Mp3 tagging song info rename revert PROBLEM!!!

Hi guys,
I can see that there are loads of people who have the same problem as me. That is... that itunes is a mp3 tagging nightmare. The problem is simple. after editing song information in itunes. sometime later, itunes will happily revert or change the info back to the original file name or only display a portion of it. Im sure you guys know what im talking bout. Someone suggested that u edit the ID3 tags with an external program. However, what i dont understand is that, my itunes last time had no problem whatsoever displaying the correctly edited song information. Suddenly, now it decides to randomly change whatever it feels like. Also, it is extremely troublesome to externally edit the song info. The whole point of itunes is to make it convenient and simple to use. What is the point of having itunes only to have to use another program to edit the info??? I have seen numerous other threads with the same problem as me. What frustrates me is that... why is Apple not doing anything bout it? and why arent they posting any solutions or answers as to why their fantastic software is behaving like a spoilt kid. Why are there no answers. It is NOT a small program. I have about 10000 songs and countless CDs. You cannot imagine what a headache it is to have spent months and months of carefully and meticulously editing the song info in itunes to perfection, only to start it up one day and find that 5000 songs are incorrectly named.
For Apple, this is just simply unacceptable.

Hey guys, i got this from the WMP help file...
"Update my music files (WMA and MP3 files) by retrieving missing media information from the Internet
Specifies that the Player automatically obtain and update missing media information for music files that are added to or are in Media Library, if the information is available. By default, the music files in your My Music folder are added to Media Library.
The Player attempts to update any missing media information in your music files by sending data about the files to a database operated by WindowsMedia.com if this check box is selected and you perform any of the following actions:
Use Media Library for the first time after updating the Player
Add files to Media Library by searching your computer
Add files to monitored folders, such as My Music
For example, if you have music files that contain the artist name but not the album name, the Player adds the album name to the file after retrieving the information from the database.
The Player also adds album art to files and music folders in your My Music folder."
In light of this information, wouldnt it be fair to say that WMp will only rename the files if they are physically added by the user in WMP? If i am not using WMP to play my mp3s, then why would WMP still be tracking and altering the file names?

MP3 tags work in iTunes 11 but not in Windows 7 - Fixed

I tagged a bunch of MP3 downloads in iTunes 11, but the artist/track/album and other information did not show up in Windows 7 file information or in Windows Media Player.
The fix that worked for me was to convert to MP3 tags to ID3 tags to version 1.0.
Steps:
-Open iTunes
-Find the songs you want to convert in the Songs view
-Right click the songs
-Choose Convert ID3 Tags...
-Check the box for ID3tag version
-Choose v1.0
-Click OK
Your mileage may vary, of course, but this worked for me and all of the embedded info was properly updated. Note that I did not have album art and I don't know if rolling back the version will affect that. Good luck.

Thanks turingtest2.
I tried your None>2.3 path and it appears to be a superior method to my original suggestion.
I hadn't noticed, but the track #s did not come through to Windows using my original method. They come through when converting to None then to 2.3. Your method, as you note, also provides the advantage of longer field lenghts. I am sure there are other advantages to 2.3 over 1, if nothing other than it's closest to the most up to date standard.
I tried converting to 2.4, but none of the data comes through to Windows.
Here is a revised set of steps. Note that this method will clear artwork.
-Open iTunes
-Find the songs you want to convert in the Songs view
-Right click the songs
-Choose Convert ID3 Tags...
-Check the box for ID3tag version
-Choose None
-Click OK
-Choose Convert ID3 Tags... again
-Check the box for ID3tag version
-Choose v2.3
-Click OK
Last comment: There may be better solutions using other software such as id3tagit, but the solution above works right from iTunes.

ITunes cannot read ID3 tags written by Perl module MP3::Tag?

Greetings,
Just trying to re-arrange ID3 information in a large set of MP3 files. Before I run the following Perl script, iTunes can read the ID3 tagging information. After writing ID3 inform ation to the MP3, iTunes no longer reads any tagging information from the MP3.
Does anyone have any information regarding this? There is some cryptic information in the MP3::Tag POD regarding setting the "id3v23_unsync" option but that doesn't seem to alter the impact on iTunes at all. Windows and other tag readers seem to be able to read the all ID 3v1 and ID3v2 tags just fine (including the altered fields) after running the following script.
Thanks for any suggestions/guidance anyone can provide.
Description: the following program takes an MP3 filename as input.
Action: It appends the value in the Album field to front of the TITLE Field. That's it! Easy!
#!/usr/bin/perl -w
use MP3::Tag;
MP3::Tag-> config(id3v23_unsync=>FALSE);
my $filename = $ARGV[0];
$mp3 = MP3::Tag-> new($filename);
@info=$mp3-> autoinfo;
@albnum = split(/_/, $info[3]);
$frame = $mp3-> {ID3v2}->get_frame("TIT2");
print $frame;
$mp3-> {ID3v1}->title("$albnum[0] $info[0]");
$mp3-> {ID3v2}->change_frame("TIT2","$albnum[0] $info[0]");
$mp3-> {ID3v1}->write_tag();
$mp3-> {ID3v2}->write_tag();
@info=$mp3-> autoinfo;
print $info[0]; //print ID3v1 TITLE field
$frame = $mp3-> {ID3v2}->get_frame("TIT2");
print $frame; //print ID3v2 Title2 field
$mp3-> close();
Thanks!

SOLVED
Changing the config entry (Line 3 in original listing) to:
MP3::Tag->config("id3v23_unsync",0);
fixed the problem with iTunes.
NOTE: This means that iTunes version 7.x still has the synchronization problem alluded to in the documentation (POD) for this Perl module. I just had the syntax wrong to set the workaround parameter.
That aside, iTunes 7.2 works quite nicely with the modified MP3. Artwork (even though this was a modified and obscure (and legal) Bible audio, it found additional information about the MP3 in the online database).
Kind Regards,

Hi Gabriel,
I think with enough patience one could get the ASCII DataPlugin Wizard to create a DataPlugin that would work for your file, but the resulting code generated by the wizard is not easily understandable, and it would not have correctly devined the sampling rate from your file format. I've written a DataPlugin from scratch which correctly reads the data snippet you sent over. I included an implicit time channel so that you could easily see the time values inferred from the "SampleRate" line. The implicit time channel rerquires all the lines in the ASCII file to be parsed in order to figure out the correct channel length (line 58), so if you have large data files you should comment out the time channel lines (44, 45, 58) and use just the implict time information already encoded in the data channel waveform properties (for faster file indexing). Unless your files are verry large, though, I think you'll like the DataPlugin as it is.
