Getting format/codec info from media file.

Hi all,
Using the QuickTime SDK I see how can retrieve metadata about the content of a media file like title, author, etc. But I can't see how to get metadata about the data itself like format, codec, bitrate, framerate, etc.
I've used code from the QTMetadata example to get me started with metadata like so:
while(QTMetaDataGetNextItem(/*... */)){
but as mentioned, it seems one can only get content metadata.
How should I go about retrieving metadata about the data?
Thanks.

Ok, well, I've found ExtAudioFileGetProperty() from the AudioToolbox framework. It works but I'd still be looking for something similar from the QuickTime framework so if anybody has got a hint, I'd still appreciate it. (Not to mention that thre's doesn't appear to be an equivalent framework for video files, e.g. VideoToolbox, which I need as well).

It may be because of your settings. You can modify that setting in System Preferences > Trackpad. Another way of making right-click is to click the app icon while holding the Control key

How to get data from media files such author, title and so on

Hi you all!

You'd have to parse the binary file header yourself. JMF doesn't have any built-in ways to extract META data from media files.
Also, don't post your question in the title and not in the body of the message. It's annoying and stupid...

Hi,
Thanks for the suggestion. I've been playing around with some of the classes of the java.net package and java.io
Using the URL class i can get the content of the data from a STATIC page and output that response to file so that is does not display to the client broswer.
But this only works if the URL i give points to a static html page.
So the problem i'm getting is if i'm righting in arguments in the URL, this means that server needs to process the arguments i give and its sends back a dynamic result. Because its dynamic the URL class can not handle this and throws me an exception everytime :(
Have u ever tried to do some things like this?

Restore from an existing backup of the iPhome

I followed the steps to restore to factory settings now I can't get back my info from a prior backup. My pads screen was frozen on the connect to iTunes I needed to restore. I had to setup my pad as if it was new. How do I acess my prior backup

Once again, KP is correct, but I just want to add that if you don't see the backup in the drop down menu on the summary page of iTunes when you choose the restore from backup option, then the backup is unfortunately gone. If you backup your computer, the iPad backup should probably be in that computer backup. I use Time Machine with my MacBook Pro and can access backups from months ago.
On a side note, I also archive backups from time to time. If you right click on a backup name in iTunes>Edit>Preferences>Devices (Windows) or iTunes>Preferences>Devices (Mac) you can save that backup or archive it. It will be date and time stamped. I have no idea why I do this to the degree that I do it, but I probably have 12-14 iPad backups archived in iTunes.

WARNING: Failed to get Network Cost info from NLM, assuming network is NOT metered, error = 0x80240037

I have couple of VMs Server 2012 R2 RTM on Hyper-v Host running the same OS.
All machines including host and VM that is not in domain have an error in Windowsupdate.log:
AU WARNING: Failed to get Network Cost info from NLM, assuming network is NOT metered, error = 0x80240037
FW and UAC are off on all. There are posts on web discussing the same error but most of them connect this to WSUS or Config Manager. And it is clear because we are touching Windowsupdate.log when troubleshooting WSUS. And because WSUS on 2012 is BUGGY this
error confuses too.
Finally, as mentioned earlier I deployed NEW server 2012 not from SYSPREP and did not place it to the domain. Updated the machine from MS update. Everything is OK beside the same error about COST :).
So now it is clear it has nothing to do with WSUS or Configuration manager. It indicates to some Network issue. But there is no clear answer. Some suggest just to ignore the error if everything is OK. But I would like to have a clean log. And it is just
interesting what could cause the problem. Is it Hyper-V stuff or Server 2012 itself. Anyway I guess I am doing right by posting a question on HV forum since here are people that should know 2012 .
Thanks.

Hi pob579,
Sorry for the late .
I want to know if your network connection indicates " unidentified network ".
If that is the case , you can try the step below :
    open the "local group policy"
    expand local computer policy -->computer configuration -->windows settings -->security settings
--> network list manager policies
    in the right pane you will see Unidentified Networks , double click it , then you can configure the
Location Type when the network connection is unidentified
    If there is domain , you need to change the same entry in "Domain Policy"
    after that please restart your computer
Hope this helps

"Could not get the audio data from the file" error

Hi
I get a lot of "Could not get the audio data from the file" errors when opening a project. Sometimes they crash Premiere Pro CC 7.01 (Mac). But if not Premiere works as usual, with the audio.
I tried to convert the audio files (coming from Audition) from 32 to 16 bit. It worked while opening a project once, but not the following times.
Where can it come from ?
Edit: I also get this error when importing audio: "Error: Premiere Pro version 7.0 is not compatible with the Premiere Pro Plug-in version 5.7.4". Maybe it is connected.

Got it! It was the Smartsound plugin making trouble. Got rid of it and no more errors.

HT1386 I want to give me old iphone 4 to my daughter and need to get all her info from her old iphone onto a new computer. The PC she synced with is dead and she does not want to loose all her contacts and music.

I want to give my old iphone 4 to my daughter and need to get all her info from her old iphone 3 onto a new computer. The PC she synced with is dead and she does not want to loose all her contacts and music. How can I do this?

To effectively transfer ownership of the iPhone requires that it be "restored" as a new device.
... The PC she synced with is dead
The iPhone is not a backup device. Your computer backs up the iPhone, not the other way around. What you use to back up your computer is up to you - Macs use Time Machine. I assume PCs use something similar.
If her PC backup is dead you will have difficulty extracting content from the iPhone since it is not designed to work that way.
All her Apple purchases can easily be transferred to another iPhone. However, her contacts will be gone, as will any music or other contact obtained from sources other than Apple.
There are a number of third party utilities that claim to be able to extract content from an iPhone. See wjosten's procedure here:

Music is missing from Media files

So I have many CD's I have copied to iTunes. I copied them years ago. I'm now trying to copy some of the music files from media to my phone (non-Apple) which requires me to do it from the media file location on my windows.
I noticed music is missing from my music on iTunes. I have not found a way to update/backup whatever to get the missing music to the media files?

"Not sure how or what caused the Compilations folder in the file path."
iTunes will put any songs for which the "Part of a Compilation" flag is set into the Compilations folder. Unless you have an older type of iDevice there's really no need to ever use "Part of a Compilation" (and even if you do, its only necessary for "Various Artists" compilations). In this example, if you select the album in iTunes, right-click > Get Info > Summary tab and set Part of a Compilation to "No" (and assuming that you have configured iTunes to manage your library) the media will be moved to C:\Users\RS Desktop\Music\iTunes\iTunes Media\Music\.38 Special\Flashback_ The Best of .38 Special.
"So after I moved a few songs over, went to iTunes to play. It says it can't locate the songs."
Ah, that may be the problem ... based on what you're reporting you have these two options set under Edit > Preferences > Advanced:
This means that iTunes determines where to store media based on Artist and Album information - if you start moving files around yourself it will inevitably lose track of it (indeed, iTunes lacks any capability to keep track of media when moved by anything else, irrespective of its settings).
"How do if I click on a song a pop up asks if I want to locate, then I can go to the media files folder and get the song, but that if individually."
iTunes does sometimes automatically fix related links when you do this - however, it can't be guaranteed to do so and there is no "bulk fix" capability built into iTunes itself.
If possible, restore your iTunes Media using a backup taken before you started moving files around. Turingtest2 has a useful script (http://samsoft.org.uk/iTunes/scripts.asp#FindTracks) that may help to resolve further issues (as always, before you start running any scripts that may modify the content of your library take a backup first).

Intel and Lion simply isnt having anything to do with my p ower mac pro G5 running leopard 10.5.8, How can i get Lion to accomodate my media files at least?

I upgraded from my
mac pro power pc, G5 ( running leopard 10.5.8 combo update)
to
an Intel iMac Running Lion,
after failing to move my data with migration assist, then target disk mode - i phoned Apple - which said id need an external drive.
I used time machine to copy my user data from my G5. However Lion will not recognize the external drive.
Ive been at this for a few days and anxious to expedite the move, mostly photos, and media files.
If Re-formatting is the only way.....is there a way to do so without another day of re-copying by firewire.
The external drive is a Ciel Lx , recomended to me by apple.
Any one else making the move from power to intel? Havent found much posted recently.

So we know more about it...

OracleSOA - File Adapter - Correct mechanism to get the line number from the file

We are using Oracle SOA process to read data from a file, process the data and write it to the database. SOA process is created using Oracle File Adapter to read the data, Oracle BPEL to transform & process the data and Oracle DB Adapter to write the data into the database.
Oracle File Adapter uses native schema to process the fixed length data in the file. The number of rows in the file may exceed more than 500,000, to support processing of large files we use chunk size in the file adapter as 4000 rows. In each read operation, file adapter reads the data that matches to the schema, there might be few rejected rows as well.
Oracle File Adapter property - jca.file.LineNumber gives me only the line number till what line the data is read. Is there any way to get the line number in the xml message, which exactly matches to the line number in the file.?
Flat File Format: (Every file has one header, trailer and multiple data lines),
HEADER02 -
L01
L01
L01
TRAILER02
Line number is one of the crucial requirement in the development of the SOA service, this is used to back trace the information from which source and line the data has come.

Hi Anshul,
Thanks for sharing your thoughts.
I am using DB adapter to insert the data into db.
While doing the xsl transformation I can get the index of the message using position(), but that is not the correct way as there can be rejected lines by the file adapter.
Even if I maintain a local counter variable, it will not consider rejected lines and increment that, which is not correct.
Thanks,
Ravindra
