FMS AAC(m4a) metadata problem

Hi, I had a little problem with the NetStream's onMetaData
Event, when I stream a .m4a file from local disk, metadata tags
display correctly; even artwork tag, but when I stream from a
remote FMS (3.0.1) some tags are missed and artwork tag is always
empty.

Sorry, I didn't mean remote share, I'm just streaming from a
regular VOD application. When I said local disk I mean without
using FMS

Isolate metadata in an aac (.m4a) file

I guess finding an AAC decoder is going to be hard.
But does anyone know a way to figure out where in an AAC file the metadata ends and the music data begins without using a decoder?
I just want to be able to grab a chunk of compressed music data and be sure its not part of an artists name or album name.
For example if metadata is always stored at the beginning of a file i could just grab some data from the end of a file.
Any ideas would be great thanks.

Well, I'm not sure how this file was encoded originally, but luckily I had "faad" (Freeware Advanced Audio Decoder) installed on a nearby Ubuntu Linux machine.
I copied the AAC/.m4a file to the Ubuntu machine.
In a terminal, switched to the directory where the AAC file was and typed "faad yourmusic_filename.m4a" which created a .WAV file.
I copied the .WAV file to the Windows machine running iTunes.
Had iTunes add the .WAV file to the library.
Selected the .WAV file in the library and did "Advanced -> Create AAC Version".
Now I also have an AAC version of the song in the library that will play in both iTunes and QuickTime.
Say, wouldn't it be nice if iTunes would actually FIX the file on its own in the first place... or at least be a little more receptive to any AAC file you can throw at it like its QuickTime brother?

Some of my songs from iTunes are AAC (m4a not protected) and some are AAC (m4p Protected). Why is this???

Some of my songs from iTunes are AAC (m4a not protected) and some are AAC (m4p Protected). Why is this???
Any insights would be much appreciated.

Because you purchased some of the songs when they were sold as DRM ( protected ) - pre itunes plus, and you bought some of the songs when they were sold as non-drm - itunes plus.
You can check quick links in the itunes store to see if you have itunes plus upgrades available for purchases.

ITunes will not import some .mp4 content, metadata problem?

I have been importing movies and TV shows for years into iTunes so that my disabled son can watch them on his AppleTV but lately I have been having a problem getting some to go into iTunes. This batch is part of season 9 and 10 of Smallville. I imported about half of the two seasons no problem but the other half will not import. I have ripped all my movies and TV episodes off of disks that I own using Handbreak and WinX DVD Ripper for Mac and it has worked just fine for over 1050 movies and 6200 TV episodes and I was able to import all of season 9 and 10 of Smallville into my laptop's iTunes no problem but on my son's iMac no luck. Both computers are running Mac OS 10.6.8 and iTunes 10.6.1(7) and all content is on two 3TB external hard drives. That is two external drives for the laptop and two for the iMac. After burning, content on one external drive is copied to the other computer's external drive and imported to iTunes on that computer. This way I have a backup copy of all my iTunes video content and two completely independent iTunes and AppleTV's. But on my son's computer 16 episodes will not go in. I "command O" like normal but no import bar is noted and no content can be found. I believe that this problem is due to metadata content. I am also have a little trouble getting some TV content to switch from Music or Movie Media Kind to TV Media Kind and I know that this is a metadata problem. Also some of the episodes have been in iTunes before either from the Apple Store or ripped and then deleted for one reason or the other. I therefore believe that there is a file in iTunes that is telling the program that the episodes I now want to import are already in iTunes and therefore should not go in twice. I have tried changing the episode names and importing, no luck and I even edited an episode using MPEG Streamclip, removing some content, and then resaving it under another name, no luck either. Any ideas would be helpful. I know the Media Kind problem has been address before but now I cannot find it so a link to that discussion would also be helpful. Thank you for any help.

I have the same issue here. My daughter has an iPod Touch4 and I have been importing mp4's with no problems up until the last iTunes update. Now I get nothing. No message, not activity, nothing. Either this is a new bug in iTunes or they have now eliminated the import ability.
I am sick and tired of apple and their hand-holding, big-brother coddling. My daughters iPod is the last Apple product we have and now I think it's time to totally part ways with Apple and go all in with Android. We have already converted all our phones from Apple to Android. The Samsung Galaxy Player looks like a great replacement to the iPod.

Converting recorded vinyl track to AAC (.M4A)

After finally learning from these forums that AAC = .M4A I am successfully importing cd tracks in compressed format (thank you!).
However tracks I have recorded to my hard drive from vinyl using Audacity stubbornly remain in .AIFF format when imported into iTunes, squandering 90mb or so of hard drive space each time.
Is there a way to import them as AAC? How does iTunes know the track is coming from HD and not cd?
Regards, Michael

You need to add them to iTunes and then use iTunes to convert them.
You iTunes prefs -> Advanced - Importing is already set to AAC.
Select the aiff files you wish to convert then menu Advanced -> *Convert selection to AAC*.
This will make a new aac version o the song.
You can then delete the aiff file if you wish.

AAC (.m4a) file can play in Quicktime player... but not in iTunes!

I have QuickTime player v7.6.9. I also have iTunes 10.2.1.1
I have an AAC-encoded file which can play perfectly in the QuickTime player. It shows the song has a duration of 3:46.
I tried to add this to my iTunes library. It shows up with a duration of 789:57:13 and iTunes refuses to play it... just moves on to the next song on the list.
What's this all about?

Exporting AAC m4a podcast mime type problem

Hi All,
I have a podcast that I use GB3 to produce the enhanced podcast with (artwork podcast with links).
When I upload this file to my server it shows up as application/octet-stream for mime type. The extension is still m4a but the desktop icon is now a quicktime movie whereas in the past it was always an iTunes icon, when I used ChapterToolMe, for instance.
As a result my podcast/rss feed on the iTMS no longer updates the more recent shows (i've tried all the tricks to get that end of things working)
I'm guessing there is some setting in GB3 that is changing the mime-type behind the scenes under the GUI. Can anyone suggest anything? Converting in iTunes all over again?

Nathan,
I wonder if you've found a solution yet? I'm having the same issue with my picture and link enhanced podcast. Whenever i post an m4a to my RSS feed, it breaks my subscription in iTunes????
I hope someone has some knowledge on a fix for this.

Unable to convert aac (m4a) to another format

I have hundreds of m4a files in iTunes, and I want to convert them mp3.
however every time I try, I get an error message
"Error occurred while converting the file "myFileName". The disk could not be read from or written to."
now, I know you'd generally think that my permissions are set incorrectly, but I've checked that the files have read/write access.... I even tried converting them to WAV and AAC instead but same issue. Weirdly, MP3 files in the same folder can be converted to another format.
I tested converting a problem AAC file outside of iTunes using 3rd party software and it worked.
It seems to be that my AAC (mp4a) files are being stubborn inside iTunes. anyone know why?

First, M4A stands for MPEG 4 Audio. It's an AAC file inside an MPG envelope. AAC is the successor of MP3, providing better quality at lower file sizes. In addition, people distributing content don't need to pay royalties to use AAC.
To convert these files to MP3 files, there is two ways for you:
#1. go to into the Preferences panel of iTunes. Click on the orange "Importing" selection and then select an MP3 Encoder for importing. Change the settings to whatever you want. Now, click OK and go back to the main window of iTunes. Select all songs you want to convert to MP3 and click on "Advanced" -> "Convert Selection to MP3".
iTunes knows a second AAC format called M4P. This is the protected version. It cant be converted to MP3 as easily. If you want to convert it to MP3, do this: First, burn the songs you want to convert onto an Audio CD (preferrably an CD-RW so you can erase it again afterwards). Now, import those songs again, this time into MP3 files.
#2.you can use a video converter software, here i recommend you Leawo Video Converter,this video converter can help you to convert aac audio format to mp3 files easily. You can find this software here. http://www.leawo.com/leawo-video-converter/
wish ican help you!

Archiving live stream at FMS and injecting metadata: VP6 good h264 not

When I record a live stream at FMS, one in which I've injected metadata in my main.asc file, the archived file plays back fine. The metadata plays back too. I'm able to retreive it just fine - if I encode VP6.
If I encode h.264 the file plays back but the metadata does not. The fact that the archived file is created and plays back tells me things are wired correctly. The only thing I changed is the format.
According to FMS docs (http://help.adobe.com/en_US/FlashMediaServer/3.5_SS_ASD/WS5b3ccc516d4fbf351e63e3d11a11afc9 5e-7e42.html#WS5b3ccc516d4fbf351e63e3d11a11afc95e-7f35)
..."The recording format is determined by the filename you pass to the Stream.get()
method."
So my record code looks like the following:
application.onPublish = function(client, stream) {
     trace("onPublish");
     s = Stream.get("mp4:streamname.f4v");
     if(s){
         s.record();
     this.doRepublish(this.nc, stream);
My code that injects the data in to the stream looks like this:
Client.prototype.sendDataEvent = function(data) {
     trace("Call to sendDataEvent...");
     this.newStream = Stream.get("mp4:streamname.f4v");
     this.newStream.send("onTextData",data);
All must be wired correctly because the metadata comes through during the live stream. On play back of the archive though, the metadata doesn't appear to be there.
Any thoughts?
Thanks

My apologies on the s.play() confusion. I had been trying different versions of the code and posted the one without it.
Whether I include s.play() or not the file gets created. Here are the various versions of the onPublish() function I've tried (differences in red):
1.
application.onPublish = function(client, stream) {
    trace("onPublish");
    s = Stream.get("mp4:streamname.f4v");
    if(s){
        s.record();
        s.play("mp4:streamname.f4v");
    this.doRepublish(this.nc, stream);
2.
application.onPublish = function(client, stream) {
    trace("onPublish");
    s = Stream.get("mp4:streamname.f4v");
    if(s){
        s.record();
        s.play(stream);
    this.doRepublish(this.nc, stream);
3.
application.onPublish = function(client, stream) {
     trace("onPublish");
     s = Stream.get("mp4:streamname.f4v");
     if(s){
         s.record();
     this.doRepublish(this.nc, stream);
All produce the same result - an archived file called mp4:streamname.f4v in my streams folder. This file plays back fine but does not play back the commands.
On your other question, about things working fine for VP6, it works fine for FLV. A file called streamname.flv is produced. This file plays back fine and does indeed play back commands baked into the file as well. This is what makes me believe the code is not the problem. If it works perfectly for one format, there would seem to be very little I could do in my code to break things for the other.
Can you try this using the record() code snippets in the live docs Stream.record() section?
http://help.adobe.com/en_US/FlashMediaServer/3.5_SS_ASD/WS5b3ccc516d4fbf351e63e3d11a11afc9 5e-7e42.html#WS5b3ccc516d4fbf351e63e3d11a11afc95e-7f35
All you'd need is the code snippets there to record your live stream and another server side function to inject commands into that live stream. Here is that function:
Client.prototype.sendDataEvent = function(data) {
    trace("Call to sendDataEvent...");
    this.newStream = Stream.get("mp4:streamname.f4v");
    this.newStream.send("onTextData",data);
Do something simple like call onTextData and pass some text in the data parameter. Then on the client side viewer, handle the onTextData method. It will receive the text. Display it in a text area or something.
If you record while injecting this text into your stream, the text should display on playback of the archived file. It will if you encode VP6/FLV, but not if you encode H.264/F4V.
Let me know what you discover.

AAC m4a podcast - Plays in iTunes, but won't sync to iPod, HELP!

Really confused with what's happening here. The podcast isn't on the iTunes store, so I know it's not guaranteed to work with iPod, but I've never had any problems with m4a or AAC files before, and I know it's supposed to work on iPods, so why wouldn't mine?

As a footnote to your answer I'd like to add the following:
I experiened this exact problem AND I had made sure that the artwok appeared in every entry. The only differrence was that I was saving the artwork to disk, selecting ALL the entries for a specific album, selecting get info (multiple) and then double clicking the artwork field and browsing my hard drive to locate the artwork.
After doing this, the artowrk did appear in ITunes but would not download to the iPod.
My solution was to still pick all the album's songs but rather than search the hard drive for the artwork, I would find it on the web and copy the image (simple copy). After this I would simply paste it in the multi artwork field.
This has worked ever since and will surely cure the above artwork problem.

MapViewer metadata problem - accessing spatial data in a different schema.

I have a MapViewer application that uses data from three different schemas.
1. Dynamic Themes come from schema A.
2. Static Themes come from schema B.
3. A newly added static theme in B whose data comes from schema C.
The mapviewer datasource points to schema B where the static themes, data and metadata are defined while the dynamic themes have their own datasource specified as part of addJDBCTheme(...).
To get the newly added map to work I've had to add a view in schema B that points to C instead of referencing directly the table and I've had to add the metadata twice, once for schema B and once for schema C.
If I put the metadata in just one of the two schemas I get the following errors.
08/11/21 13:58:57 ERROR [oracle.sdovis.ThemeTable] cannot find entry in ALL_SDO_GEOM_METADATA table for theme: AMBITOS_REST
08/11/21 13:58:57 ERROR [oracle.sdovis.ThemeTable] java.sql.SQLException: Invalid column index
OR

ORA-13203: failed to read USER_SDO_GEOM_METADATA view
It's not a big deal but I'd like to know if anyone else has has similar problems.
Saludos,
Lew.

Hi Lew,
if you are using a recent version (10.1.3.1 or later) there is no need to use a view and to create the metadata in both schemas.
You need to grant selection on tables between the schemas.
You can try the following. Assume you have the MVDEMO schema (from MapViewer kit) and SCOTT schema.
1) grant select on MVDEMO Counties table to SCOTT
SQL> grant select on counties to scott;
2) Now you are ready to create a predefined theme in schema SCOTT using the MVDEMO Counties table.
- Open MapBuilder and loads the SCOTT schema.
- On the Data navigator (bottom left tree), go to Geometry tables and you should see the MVDEMO node and the COUNTIES node inside it.
- Start a wizard to create a geometry theme based on this Counties table.
- At the end you should see that the base table name is MVDEMO.COUNTIES. Therefore MapViewer will use the metadata in MVDEMO schema and there is no need to replicate it in SCOTT schema.

Adobe CS3 Bridge - Metadata Problem

Hello,
Alot of my images (JPGs) seem to be losing their metadata, for example, if I keyword a bunch of pictures in bridge and save them. I go back the next day, and they are missing? Also when uploading to a website, if I put in copyright like this:
© Copright Name 2008
it almost always appears like this when on site:
Á© Copright Name 2008
Does anyone have any idea how, and why this is happening, and if there is a way to resolve this incredibly annoying problem.
If it's any relevance, I am seperating keywords with commas.

It should be possible to batch remove that using a metadata template where you set that particular field to be empty and then append that template to all your files (and of course, test on some random pics before doing something like this on all your images)

List view threshold and columns manage metadata problems

Hi
We have problem in our company since we have more files in library than is set in List view Threshold.
I have created index on column "year" and create view filter: Year is equal 2015.
and I get famous error: this view cannot be displayed because....
I haven`t find any limitations on column type: manage metadata?

Hi,
As I understand, you encountered the issue after you created view filter.
Every column type has the default number that can be created. You should go to check the number of your column created is less than the number by default.
Per my test, I can achieve it without exceeding list view threshold.
Check things below:
1. You can increase the number of the list view threshold, and after that, you can try again to see the same situation will occur.
2. Go to create another managed metadata column “year”, and create index on column "year", and create view filter in the same list to see the issue will occur.
3. Check ULS log to see the details about the cause of the issue.
Best regards,
Sara Fan

Premiere Pro CS5.5 Mac - Major Metadata Problems

Hi...
I am having major problems with the Metadata system in Premiere Pro CS5.5
I have created a custom scheme and added the following property "Key" and set it to have a boolean value (Check Mark)
My Metadata display correctly displays the "Key" property and I can check it. Just like expected.
I will now apply it to the clip(s) in need of that meta property.
In the project column the property is also show correctly...
All good so far but now comes the two major problems
PROBLEM 1
1) I have about 300 clips in the project panel
2) If I click the column header I can sort accordingly
3) Clicking name or Labels will immediately sort correctly. 1 Second tops.
4) If I click the column header of my custom propert "Key" I get the SWOD and it takes about 120 seconds for Premiere to sort adhering to the Key Column.
2 minutes for that is a VERY long time compared to sorting by name...
Could this be a bug or am I doing something wrong...
PROBLEM 2
In the project panel's search field I will enter "Key" but nothing will appear... At least that is what I thought.
It took more than ONE HOUR for Premiere's search results to be able to identify that a clip had gotten that property checked. (Clicking the Clip immediately reflects that it has been checked)
I even timed it. Ckecked the Key property for 4 new clips which did not have the meta applied to them.
In the search field I entered 'Key" but only the clip which had had the Key meta tagged since 1 hour would appear.
I waited another hour and now those very 4 clips also appear in the search field. The same goes for the "Good" meta boolean which is NOT a custom field.
I saved the project in between quit Premiere and re-launched but THAT did NOT help PPRO find that Property in the search field.
As I said, it takes about 1 hour for Premiere to be able to included those metadata in the search results.
Funny thing is, if I enter 'true' which is the boolean text-string for a checked property the results appear immediately. But there is NOT much use in having ALL boolean fields appear that are checked.
I welcome that adobe implemented metadata across their apps but ELEGANT is something entirely different.
Could anyone shed some light on this ?
Thanks

AIFF metadata problem

Hello,
When editing metadata for my ALAC/AIFF files, I use the Album Artist Sort Order field (i.e., Sort Album Artist in iTunes) so that artists like 10,000 Maniacs will alphabetize to "T" (i.e., Ten Thousand Maniacs). While I have had no problem with the metadata "embedding" in my ALAC files, I have found that this data embeds transiently in AIFF files (i.e., it will be there for a few days and then disappear).
Has anyone else experienced this issue? Does anyone know of a fix/workaround?
Thanks,
Tim

Can you please state the full nature of your current issue, how you reproduce it, and examples in your site? Also, please post your site's domain.
Thanks.
