Steganography in JPG or MP3 files

Does anyone have any information or code about how to hide information in JPG or MP3 files?
Thanks!

You can do this, but I would discourage using MP3 files, because they seem to cause a lot of trouble. I would convert the mp3 file to AIFF using iTunes.
There is a feature in iMovie called the Beat marker feature. You can drag in an audio track to an empty project. You can then open the audio track in the clip trimmer and add beat markers. Later, you can add video clips or photos to the project and they should snap to these beat markers.
There is a good tutorial here.

The title of my initial post is a bit misleading. I already took a chance deleting one of the iPhones, hoping if I deleted the wrong one, I can still reauthorize it (all with the same Apple ID acct, so not subject to 90-day waiting period, right?) The iTunes database just updated itself, and it says I have 4 "devices" "in the Cloud", but 5 "computers" associated w my account. How can I find out what computers are associated? Isn't there a list I can see? I dont have a clue what computers they might be. If I use the "Deauthorize All" option, is it a pain to add them all back in. I assume I would have to log in from each computer to reauthorize each one. Would I have to be running the newest OS or version of iTunes to reauthorize? I think I have a PowerBook G4 Titanium with an older OS and iTunes. I'd like to keep that authorized, if possible.

Help on Opening .JPG and .MP3 files

Dear Forum Members,
I have purchased a new 20inch imac a few day ago and is having difficulties opening files from an external hard-disk. The files were saved using a window XP computer (it crashed and died - thus my move to imac). I can see the files on the external hard-disk, but the imac hangs (e.g. cannot force quit iphoto or itune) when I try to open any file, regardless of jpg, mp3, mov extensions.
I would greatly appreciate your help as 5 years of my children's photos are on it, including my whole collection of scanned CDs.
Thanks
Dan

What happens if you try to copy these files to your iMac first? Your problem may not be that applications quit when opening but rather you're having problems simply accessing the disk.
If your external disk was formatted as NTFS by your Windows machine then your Mac will not be able to write back to the disk. Your applications may be attempting to save temporary or permanent files back to the disk. Verify this by going to the Apple menu and selecting "About This Mac". Click the "More Info..." button. Under the Hardware section on the left, look for your drive. It's probably under ATA. Select your drive and look at the "File System". If it is formatted as NTFS, you can copy the files to your iMac, and use the Disk Utility to reformat the drive to a Mac or MS-DOS format.
This could also be a symptom of disk corruption. You can begin troubleshooting by using the Disk Utility found in /Applications/Utilities to verify/repair your disk. If Disk Utility finds problems but is unable to fix them, you can purchase third party tools such as DiskWarrior or TechTool Pro to attempt to repair your disk.
Hope this helps! bill

How can I extract both my mp3 file and its associated .jpg out of itunes

Hi everybody,
I'm a DJ and once a month, I like to share a set of mine with my friends. For each set, I also make a dedicated flyer.
I usually put the recorded set in Itunes, then I add the flyers using the "Illustration" (I'm using a French version) tag.
Then, I drag the new file (both the .mp3 and .jpg) on a folder on my computer and I can see the flyers and not the normal Mac icon for music file.
I had always worked, but today I tried to do the same but it doesn't work anymore. In Itunes, my mp3 file contain the flyers, but when I drag it to another folder, the flyer is not there anymore.
What happened???
does anybody know a freeware to associate a mp3 with a .jpg?
Thanks for your help,
Have a nice day
Jean

Bonjour.
I'm not firm with the french iTunes but I'm sure its similar to all other iTunes in the world, except the language of the menus.
You can include the cover (Illustration) inside the music file. mp3, AAC or Lossless makes no difference.
To do so go to:
The song (or songs) by marking it (them) in the main iTunes window. Then right click mouse (or two fingers on touchpad) and choose "Information"
In the information window go to the tab called "cover"
Move the wanted picture via drag & drop into this window. The best format for such illustrations are 500 x 500 pixels. If yours are bigger then iTunes will resize it to fit.
Click on save
If you will change the cover for more than one file (song) you will be ask "you are sure to change all files"
Simply press ok
After that the cover will show up in iTunes and will be exported within the file if you pass the song to others..
There is no reason to place the cover / Illustration in the Music folder cause iTunes uses for imported covers the "Album Artwork" Folder in the Library.

Music plays in iTunes, but NONE of the MP3 files are visible in Explorer

This one is a bit of a mystery.
When I open up any of the folders in my iTunes Music folder, they appear to be empty. No MP3 files are listed at all. Yet, iTunes can still play the music.
Here are the details:
1. I keep my iTunes media content on an external hard drive, and iTunes is working fine. Some albums have disappeared but most of my music shows up in iTunes and plays properly. Therefore, the music files have to be there.
2. When I right-click on my iTunes folder in Windows Explorer and choose "properties" I get a result: Explorer scans the folder and tells me I have 98.8 gigabytes in 18,279 files, (though when I look around, I see that a LOT of albums are missing). Yet, Windows Explorer is finding a lot of files even though I can’t see them.
3. However, when I right-click on a folder inside my iTunes folder and choose “properties” (the folders for each artist and for each album are still there and still visible) I get weird results. It says that there is some small amount of data in each folder (27 kilobytes or 35 kilobytes) and some random number of files (2, or 5, or 6). It doesn't matter how many songs are actually on that album, it just gives me this small unrelated number. Yet, I can’t see any files listed at all.
4. Under the View tab in Folder Options, everything looks fine to me. I don’t see a setting there that would hide MP3 files.
5. I tried checking “show hidden files” and all that sort of thing, but nothing changed.
6. I did a virus scan and it revealed no threats.
7. I also went into the Command Prompt and used the dir command to see what was there. I could see all of my folders including my iTunes music folder. I have pictures, Word documents, Excel files, etc on this external folder as well. I can see all of these files no problem. I can also see all the Artist and Album folders in my iTunes music folder. However, even using the dir command, I can’t see any songs – there are no MP3 files visible. I reveal hidden and system files (dir /ah), I then see some files like these:
desktop.ini
AlbumArtSmall.jpg
Folder.jpg
8. I tried to play the music from VLC media player and Windows Media Player, but that doesn’t work because the files can’t be seen by those programs either.
9. However, when I open iTunes, all the music is there and playable. Only iTunes sees the music.
Anyone have any idea what could have happened? The one thing I changed recently is that I ran the iTunes Genius function. It scanned my music and did what it was supposed to do, and it worked fine. I doubt that Genius could have done this to my external hard drive. I’m guessing I picked up a computer virus somehow, but my virus scan doesn’t reveal anything.
Anyone have any ideas about what is going on?
Thanks!
Doug

OMG!!!!!!!!!!
You were absolutely right, Rob. I couldn't believe it when I saw it. I've got nearly 200 Artist folders with 1,000 or so Album folders - and they are all completely empty of music.
But in the middle of that long list of folders, there is an innocuous looking folder labelled "Music." I looked inside that folder and, bam, there they were - all 92 gigabytes of my missing music files in a complete copy of all those Artist and Album folders.
I thought I was going crazy! How could iTunes be playing all this music when as far as I could tell, it had all vanished? But there it was. As you said, iTunes had simply moved it down a level in the folder hierarchy and then didn't delete all the original folders.
And as I scanned the original list of Artist folders, I also saw the other folders: Podcasts, Audiobooks, iPod Games, etc. I hadn't even noticed them before. I just assumed that all the folders I was looking at were Artist folders.
Thank you so much, Rob. I'm not sure I would have ever solved this "case of the missing music files" on my own. I would have continued to bang my head against "hidden files" settings and all that. Perhaps I would have tracked these files down by looking for their location using "Get Info" in iTunes. But maybe not. I had no reason to suspect that I didn't know where the music files were: after all, the Artist and Album folders were all right there. They were just empty! I was so focused on the folders being empty, it never occured to me that iTunes had created exact duplicate folders somewhere else.
Do you know if iTunes had any practical reason for leaving all those empty folders behind? I'm just wondering if it is safe to manually delete them. I noticed, for example, that they aren't completely empty. They contain hidden files of Album Art and various ini files. I wouldn't want to delete them and then find out that I just deleted all my album art and a bunch of important settings files.
Thanks again. You saved my neck with this one.

How do you force itunes comments to ID3 tags in MP3 files?

I have comments all throughout itunes. The mp3 files do not have those comments in the ID3 info.
How do you force itunes comments to write out to ID3 tags in MP3 files?
The folder and files all have write permission.

Yeah, don't do that, you probably also degrade the sound quality... If you've confirmed it is something odd with multiple tags try this.
Select a group of mp3 files (You might want to start with a smart playlist so you don't mess with any other format)
Right-click and use Convert ID3 Tags > None (may need to repeat this step if multiple tags)
Then right-click and use Convert ID3 Tags > v2.3 (v2.4 support still patchy from various accounts)
Downside is that it will lose any embedded artwork, but it should preserve all other meta-data, both tag-based and stored within the library itself.
In fact, if you use my CreateFolderArt script before and after updating the tags it should archive any artwork as a local Folder.jpg image for each album and then reinsert that image on the subsequent run... Check it out on a single album first. If it doesn't work as expected let me know and I'll tweak the script to achieve this end.

How to embed .jpg in MP3

Hi.
I am seeking a way to embed .jpg-files to MP3-files. I know that logic has some options on how to embed ID3 tags to mp3-files, but I cannot find any way to embed .jpg-files. Basically, I just recorded an album which I want to put on my webside, so that people can download it. I want to make sure that whenever people are importing the album in to iTunes, they have the cover-art.
I hope that you understand my question.
Cheers
Rasmus A.

Just did this yesterday.
After bouncing the tracks to iTunes, I used the Get Info command to fill in all of the tags -- including adding a JPEG file for cover art.

How do I save all mp3 files as an attachable file in text messaging on a G'z One Commando? Some mp3 save as these types of files but I don't how or what I do differently.

How do I save all mp3 files as an attachable audio file in text messaging on a G'z One Commando? Some mp3 save as these types of files but I don't how or what I do differently.

In summary, it sounds to me as though the Mac concept of "hidden extension per file" isn't embraced at all by Photoshop.
So assuming the extension is always visible, what is the easiest way do each of the following (ignoring issues with integration with other apps):
1. Save a JPEG as: abc.jpg
2. Save a JPEG as: abc
3. Save a JPEG as: abc.
4. Save a JPEG as: abc.xxx
Since it seems to me we still haven't nailed down whether there's a disparity between how this works on Photoshop for Mac vs. PC, I'll answer the above questions for PC:
1. File - Save As, choose Format: JPEG, type (replace filename with): abc
2. No difference than 3 on a PC.
3. File - Save As, choose Format: JPEG, type: abc.
4. File - Save As, choose Format: JPEG, type: abc.xxx
How is it different from the above on a Mac?
Is there something more complex, such as the sequence of operations, or another system setting, that I didn't cover here? I normally always keep Explorer set so that file extensions are visible (it's global on a PC).

Downloaded album art not saved in mp3 file?

When I use iTunes to download missing album art, that art is not being saved in the MP3 file. I verified this behavior by checking that the file timestamp and size didn't change after the art was successfully downloaded and displayed within iTunes. As a second check, I also deleted the music from my library and re-added it, and the art work is missing again.
Only if I drag the jpg image to the blank artwork window does it seem to "stick".
Any ideas? Thanks.

Yes, if you download album art through iTunes and then later manually add art to the tag, the downloaded version is replaced. I think it still remains in the folder on your computer, but it does get replaced in the native song file. What I'll do is download the artwork from iTunes, then copy it and paste it directly into the tag for a permanent "attachment" to the song.

Script to encode jpg and mp3 into video for youtube?

Hi!
Sometimes I upload music and stand-up to youtube. Till now I used wine + avisynth + virtualdubmod to achieve this. Lately I realized that there is another smipler way to carry out things: ffmpeg
I was looking for some script or one-liner which makes the encoding task, but unfortunately none of those mentioned scripts worked. They are all obsolate that are mentioned by others. Some of them works, but the resulting video are denied by youtube. Do anybody know a simple one-liner or script (or maybe a handy application) which can do the transcoding the right way?

You don't say if you want 1 or multiple .jpg images in the video.

Script to encode jpg and mp3 into video for youtube?
With x264/mp3 into a mp4 container? Any number of ways. Here are some examples.
ffmpeg -r 1 -i file.jpg -i file13.mp3 -c:a copy -c:v libx264 -b:v 500k ouput.mp4
ffmpeg -loop 1 -i file.jpg -c:v libx264 -t 30 -i file.mp3 -c:a copy out.mp4
ffmpeg -f image2 -i file.jpg -i audio.mp3 -c:a copy -c:v libx264 -b:v 500k output.mp4
Find out how you want to do, then if you want a script to automate it, something like
#! /usr/bin/env bash
echo "What image file?"
read image
echo "What audio file?"
read audio
echo "what video size?"
echo "Example: 640x480"
read size
echo "Output file name?"
read name
ffmpeg -f image2 -i "$image" -i "$audio" -c:a copy -c:v libx264 -b:v 500k -s "$size" "$name".mp4
exit
If you want to use multiple images, look at ffmpeg docs.

ITunes Artwork with no embedded covers in the MP3 files ?

Hi
New iTunes user,
I have a question is it possibly to have artwork displayed in iTunes without having embedded artwork images actually in the MP3 files ?
I use Windows Media Center and WMP12/7MC just uses the Folder.jpg Hi-Res cover image in each albums folder.
It appears iTunes only shows any covers if I embed covers in to the MP3 files which I'd rather not do.
What are my options if any?
Many thanks.

I have my entire music collection ripped using iTunes and stored on a Mac mini running Windows. It is all in Apple Lossless format and shared with Windows Media Player and Media Center which can play the Apple Lossless files thanks to a solution I came up with along with assistance from Milenko Mitrovic.
While I do deliberately chose to embed 600x600 pixel artwork in each track (disk space is cheap), I also put a folder.jpg of the same artwork in each album folder for the benefit of WMP and Media Center.
The steps I use to do this are as follows.
1. Rip the CD using iTunes
2. Tell iTunes to download album artwork for that Album. Life is made much easier if you only do one album at a time.
3. Look in your Music folder for the iTunes folder and look in that for the Album Artwork folder
4. In the Album Artwork folder will be a Download folder and in that various subfolders eventually leading to a file called something like A392573AD3DE300C-45855BDAB6F38792.itc2 by checking the file creation date/time you will be able to confirm it corresponds with the one you just downloaded.
5. Use the free utility bitmaprip available here http://mark0.net/soft-bitmaprip-e.html to 'extract' the real artwork from inside Apple's proprietary itc2 file. You can then move this to the iTunes album folder for that album and name it folder.jpg
If you then like I do, want to make this artwork embedded, then do the following extra steps.
6. Select one of the tracks for the album
7. Copy the artwork to the clipboard
8. Clear the downloaded artwork
9. Delete any folders left in your Album Artwork folder so they do not confuse you for the next album
10. Select all the tracks for the album
11. Paste the artwork in

Can't tag my MP3 files

Best regards, Mosa!

Make sure you have FULL control over the entire folder where that song is. It might even be a permissions problems on the folder(s) above it.
Also in Vista, it sometimes isn't enough to have read/write control. You need FULL control.

How can I copy mp3 files from my Itunes library to an SD card for use in a non-apple phone?

How can I copy mp3 files from my Itunes library to an SD card for use in a non-apple phone? I can physically copy the tunes as mp3's but the phone does not seem to be able to play all of them. Do I need to copy an entire album or can I just pick & choose individual songs? The phone is question is an LG running who knows what for an operating system.

AAC is Advanced Audio Coding. Basically it's a format that sounds better than MP3 but doesn't take up as much space as a lossless format (like you'd have on a CD). More than likely you've had that encoding turned on when you ripped your music into itunes (it's the default encoder). Therefore your LG phone won't play them.
You need to turn off the AAC format by going to the iTunes menu, Preferences, General (at the top), then clicking the "Import Preferences" button. Change the AAC Encoder to MP3 Encoder. After that you'll have to make MP3 copies of your songs by right clicking them and selecting "Create MP3 Version." You'll get a copy of the song that should transfer to your SD card and have MP3 encoding. Hopefully your phone will play that.

How can I put my mp3 files into my iTunes library? Every time I download a song from a website and try to drag it to my library, it won't add on. How can I fix this?

Back then when I had the older update with iTunes i never had this problem with trying to put my mp3 files of music into my iTunes library. Now it doesn't want to be put into the library. Once I try to drag the music file to the iTunes library nothing happens, it just keeps showing a cancellation sign with my mouse. So how can I fix this?

Hi William.
The problem is probably that the index is corrupt and you need to completely re-create it rather than rebuilding individual mailboxes. I have no idea what the situation really is now after having tinkered with the contents of ~/Library/Mail/, though, so the following procedure may or may not work.
Verify/repair the startup disk (not just permissions), as described here:
The Repair functions of Disk Utility: what's it all about?
After having fixed all filesystem issues, if any, and making sure that there’s enough space available on the startup disk (a few GB, plus the space needed to make a backup copy of the Mail folder), try this:
1. Quit Mail if it’s running.
2. In the Finder, go to ~/Library/Mail/. Make a backup copy of this folder, just in case something goes wrong -- e.g. by dragging it to the Desktop while holding the Option (Alt) key down.
3. Locate Envelope Index and move it to the Trash. If you see an Envelope Index-journal file there, delete it as well.
4. Open Mail. It will tell you that your mail needs to be “imported”. Click Continue and Mail will proceed to re-create Envelope Index -- Mail says it’s “importing”, but it just re-creates the index if the mailboxes are already in Mail 2.x format.
Note: For those not familiarized with the ~/ notation, it refers to the user’s home folder, i.e. ~/Library is the Library folder within the user’s home folder.
