Failed to realize
I am trying to download a mp3 content from a server using JMStudio but keep 'Failed to realize' message in the JMStudio. I captured the traffic and noticed that the Client send DESCRIBE request and the server replies with SDP content but then the client does not do anything and sends a FIN after a minute. Below is the TCP Stream:

Sorry for not being that clear yesterday, but I didn�t really understand the problem. I have now sorted it though, so it�s ok.
In my app, I have a JTree containing File objects, representing a directory structure of folders and mp3 files. The idea is to play whatever file is selected.
The problem was that I had a TreeSelectionListener that would place the selected file. This was fine, if only one file was selected. But as I merrily drag my mouse across the tree, a number of files were selected at once. I believe the player got overloaded, and so now I play the selected file(s) on mouse release and only if there is at least one file selected.
However, I have now found another place the error seems to inhabit.
I also wish to use a JFileChooser to load and save mp3 file.
Loading is the easy part, but it doesn�t seem to save correctly.
Here is my code to save:
public void saveTo(File to) throws
FileNotFoundException,IOException
// Create channel on the source
FileChannel src = new FileInputStream(file).getChannel();
// Create channel on the destination
FileChannel dest = new FileOutputStream(to).getChannel();
// Copy file contents from source to destination
dest.transferFrom(src, 0, src.size());
// Close the channels
src.close();
dest.close();
However, this seems to save an object and not an exact copy of the mp3 file (file).
Does anyone know how to make an exact copy, with the exact format, of an mp3 file?
Any help would be greatly appreciated.
Thanks
Luke

The media used in the Applet is an avi file and runs in all major Player.
The code is same as in jmf examples, is there something special needed to run JMF in an Applet.
Please reply as this would decide whether to use JMF in creating customized media player in a project.
Thanks
ShuvankarCan understand your concern but you will have to take call what is your use case and what you are ok with and what you are not ok with.
"record" mode would automatically take care of file clean up - in sense that will overwrite data. But then if you consider "accidental" stop of your encoder and restart like you mentioned , if you wanted old data to be there - you will loose it with record option.
Since you have Interactive edition - there are lots of ways you can handle it. One of the ways - is like you can use flag to decide whether its first publish to the application - if yes use record mode or else use append mode (but then again accidental unloading of application will reset the flag - but this ideally should be very rare if things are working fine on server-side unlike encoder restart which can be due to network)
Please feel free to post again if you need any more help. -
Spotlight mysteriously re-indexes after some failed searches?
Well here's an odd one:
About a week ago I had occasion to migrate a "standard" account from one Leopard computer to a fresh Leopard computer where it became the second account on the new machine (after the Admin account). This was done with Migration Assistant and completed without problems.
The original account was inherited from a Tiger 10.4.10 installation on the old machine via a default, "upgrade", install of Leopard.
Spotlight searches of the Home directory of that account worked just fine on the old machine. There is nothing in the Spotlight preferences Privacy list in either the old machine or the new machine. It may be relevant that the old machine was the Powerbook listed in my tag line below. The new machine is a Macbook. I've had no other Spotlight problems on either machine.
Today I had occasion to search for a folder in the Home directory of this account on the new machine. To my surprise, it did not show in the results. OTHER stuff showed up, but not this folder.
So I opened a Finder window and did a Command-f to bring up the search criteria and started playing around with search criteria (specifying "kind" = "folder" for example) to see if I could isolate the problem. Periodically I also retried searching in the regular Spotlight drop down to compare results. The upshot was that it seemed NOTHING in the Home directory of this migrated account had been indexed.
And then, for no obvious reason, and about 5-10 minutes into poking around like this, I discovered Spotlight was "indexing". It had about 20 minutes of indexing to do.
Again, I had not been doing anything in the Spotlight preferences -- just trying different search criteria in the Finder window. So why index now?
When it finished indexing, searches for files or content in the Home directory of this account, either via the Finder window or the Spotlight drop down, all worked fine.
NOW, why should Spotlight decide just at this moment to index this account? The account has been in heavy use on this machine for about week (although I had not had occasion to do searches in it).
And the indexing didn't start until about 5-10 minutes into the search and re-search process trying to explore the limits of Spotlight's "blind spot".
Does Spotlight fail to realize it needs to index a migrated account?
Does Spotlight have some sort of fail safe mechanism where it revisits the need to index things after so many repeated searches or searches with no results?
Mysterious indeed.
--BobReview the hits from a google search for socket(PF_ROUTE). IMO, something's blocking access, most likely mucked up permissions on the server; however, I don't muck with servers or AD and you might be better off perusing MS's forums for AD info.

Cannot realize processor: webcam to RTP
Hello,
I am having trouble converting the DataSource I get from a VFW webcam (Intel Easy PC Camera) into a source suitable for streaming over RTP. I get a strange "Failed to build a graph for the given custom options" error when I try to realize the processor.
I am using the following code to transcode the camera's video source to a H261_RTP source to give to an RTP data sink:
DataSource camera = Manager.createDataSource(new MediaLocator("vfw://0"));
Processor processor = Manager.createProcessor(camera);
waitForState(processor, Processor.Configured);
// Should only get the VFW video track
if (processor.getTrackControls().length != 1)
return;
VideoFormat vfmt = new VideoFormat(VideoFormat.H261_RTP, null, Format.NOT_SPECIFIED, null, Format.NOT_SPECIFIED);
(processor.getTrackControls())[0].setFormat(vfmt);
(processor.getTrackControls())[0].setEnabled(true);
ContentDescriptor cd = new ContentDescriptor(ContentDescriptor.RAW_RTP);
processor.setContentDescriptor(cd);
waitForState(processor, Processor.Realized);When I call the second waitForState() (which calls processor.realize()), I get the following error:
Failed to build a graph for the given custom options.
Failed to realize: com.sun.media.ProcessEngine@60b6f5

outputting to: RAW/RTP
Error: Unable to realize com.sun.media.ProcessEngine@60b6f5Has anyone hade trouble converting from a YUV video format to a H261_RTP video format? Is my camera out of the ordinary for being YUV?
The problem is I know this can be done with JMF because the JMFStudio fires up my camera and streams it out perfectly. From looking through the JMFStudio source, it basically just sets the final format type for the video track and lets the Processor or whatever handle all of the intermediary conversions when realize() is called. I thought that's what I'm doing too, but haven't found where I'm going wrong.
I adapted my code from the VideoTransmit.java example program, which encountered the same errors.I have a similar problem. I am currently using a Intel camera (think it's easy pc). In my case, I am trying to create a processor to handle both the audio and video streams and I get an error when I try to create a send stream. The log file contains either JMF complaining about not being able to open com.ibm.media.codec.video.h263.NativeEncoder or not being able to transcode between different YUVFormats. The encoder seems capable of handling only 3 sizes when encoding.My initial try was to specify a YUV format which could be processed by the encoder. But I kept getting stuck in specifying the datatype when creating the desired format. Any ideas anyone ???

Codec stops the processor from realizing
Hi, I am trying to build a solution which transmits a webcam stream to two computers simultaneously but with a different overlay on each. The idea being that each computer ends up with the same stream but with different watermarks on top of it. I have created two processors which run as threads and set an overlay codec to the data flow path of each processor. However when I set the codec to the data flow path the processor will not realize and I get the following error.
Failed to build a graph for the given custom options.
Failed to realize: com.sun.media.ProcessEngine@c21495
Cannot build a flow graph with the customized options:
Unable to transcode format: RGB, 320x240, FrameRate=15.0, Length=230400, 24-
bit, Masks=3:2:1, PixelStride=3, LineStride=960, Flipped

outputting to: RAW/RTP
Unable to add customed codecs:
videowallfinal.Transmit2$OverlayCodec@8814e9
Error: Unable to realize com.sun.media.ProcessEngine@c21495
The processor works fine if I take out the setCodecChain part so I'm guessing it has something to do with the codec. Any help would be much appreciated. I will post the code below.Here is the code for the processor, a cloneable dataSource is created from the medialocator (webcam) in another class but I havn't added it becuase it would be too long. Thanks again.

I am tring to create player with input stream ( getting from RTP packet after removing 12 byte header). after player creation during realize it gives following error.
Failed to realize player: Malformed wave media:expected 'RIFF'
i m sending stream stream from javasound and getting at j2me application with payload type 5.
my application code is following

Please HELP, nothing working! Secure Link to iTunes Store failed
I am going absolutely insane here, I cannot fix this problem. I have been searching Google for hours trying every single thing that people recommend, NONE of them are working. This is ridiculous, something has to work to fix this, please help, I'm getting increasingly frustrated with this issue. My internet works just fine, there is no connection issue that I am aware of. I tried all the things that Google search came up with, none have yet to solve this issue. Please someone HELP!!!
And to answer questions I am sure that will come up:
YES iTunes is enabled through Windows Firewall
YES I have tried uninstalling and reinstalling iTunes
YES I have tried turning off Windows Firewall
YES I have tried turning off my anti-virus software
YES I have tried uninstalling my anti-virus software
YES I tried the command prompt Winsock netsh reset
Anyone have any ideas that I haven't yet come across? I'm at a complete and total loss for what to do and I need my software to work properly. Thank you so much.Here's my diagnostic test results in case this tells someone something useful. I did notice that it says iTunes is not enabled in Windows Firewall but this is false, I checked and it is in fact enabled, not sure why iTunes fails to realize that.

I am attempting to use code from the Cut.java sample to cut multiple
regions from the same source audio file to separate destination files.
I am calling the doIt() method from my coding, passing MediaLocators to
the input and output files (both .wav) , and arrays with a single
element (time in ns as a long) for the start and end, and false for
frame mode. The first time I call it, it works fine. However, on
subsequent calls, despite the output messages suggesting it has worked
successfully, the output files are full of white noise. I have tried:
using a new instance of Cut each time
adding code to close the processor and disconnect the datasink
disabling JMF buffering
all to no effect. Any suggestions would be greatly appreciated.
cheers
Matthew Wilson.I have kind of the same problem too.
I copy-paste the "cutting sections from an input" example from http://java.sun.com/products/java-media/jmf/2.1.1/solutions/Cut.java but can't get it to work.

If i connect my MacBook Pro to a tv through the mini dvi port (via vga or hdmi) will i get sound or just video?
ThanksJoJohn: If your MBP was manufactured after April 2010, it sends an audio signal through its mini-Displayport. If it's an earlier model, it doesn't.
There are several third-party HDMI adapters on the market that claim to carry audio when the computer provides it through that port. Reports have been mixed about all of them, probably including some adverse reports from people who fail to realize that their older machines don't send audio through the mini-Displayport.
To find such adapters, Google "mini-displayport to HDMI". Read the specs for each adapter carefully to learn whether or not it claims to support audio. -
Hi,
I m new to JMF.We are using MjSIP and i want to transmit video through JMF to other machine.The problem is the implementation which is given in MjSIP isnt working .
I mean whenever i execute the implementation given in mjSIP like JVisualReceiver etc.Both machines hangs coz they are not being able to realize the processor.I have successfully run the Player but i m getting problem in realizing the processor.
Although we are using the same processor.realize() method given in JMF Api.
Even i m not being able to run this sample given by SUN.

Hangs after updating to 10.4.5
896MB RAM
G4 DP 500MHz
I've had no problems with 10.4.4 but saw the software update pop up on my desktop. (Big mistake.)
Updated via software update with no interruptions. Restarted as directed. Problem: OS X will show progress bar moving left to right. Normally, as soon as the bar hits the right side, the login screen appears. That's not happening. OS X is hanging.
I've read that some folks have rebooted in Safe Mode. That didn't work for me. I've read that some had problems with the Startup items. That didn't work for me. I've read (after previous upgrade problems) that some folks had problems with Cache files. That didn't work for me. I even removed the Extensions.kextcache file (and the other one) with no luck. OS X is still hanging. I removed all connections and extra RAM with no luck.
I could be wrong but I think the problem lies with login since OS X is moving along all the way until the login screen is supposed to appear (but doesn't.) I've found these files: waiting4loginwindow.pid and loginwindow.boottime. Both are the most recent files that were modified at or after the time of software update to 10.4.5 from 10.4.4.
I'm at a loss as to what to do next (besides a painful reinstall back to 10.4.) I've rebooted to OS 9.2.2 to submit this question. Thanks in advance for any suggestions.It seems to me that some fail to realize that Apple did not intend for all this mess. Just think about that for a moment. Why would Apple permit the Software Update to automatically appear, permit you to update the software, all without insisting you do the following: Verify/Repair Permissions, take out all extra RAM, disconnect all wires (except the power and display,) etc., etc? It's because MacOS is supposed to be simple.
Some of us have found glitches. I think I found a simple glitch. So simple, it has cost me a day's worth of work. I still haven't been able to find a solution.
If you read other problems and the solutions are recommending reinstall, you are essentually reading about our MacOS becoming more and more like Windows. Not good. Stating that all updates should be applied only after you have done all of the above is not good either. I think I've learned my lesson to not update any more.
If you do have a solution, thanks in advance for any info. (Rebooted in OS 9.2.2.) -

I have a jpeg movie file 60 mins long and a text file tell me five time-lines for breaking the movie. For example, break the movie at 10:21, 16:05�
The final output should be five small jpeg movie files. Each file contains a 90 sec (30 sec before the break time and 60 sec after the break time).
Do you know any java library (jar) contain the library that can help me on programming this? Any existing source code? Any SDK for a movie editor can do that?
Please help.
Thanks

Is there a way to run flash player on iPAd?
I am rather unhappy that I cannot run FlashPlayer on my iPad. I can't run most of my weather sites without it. As a boat captain I rely on weather sites for safety among other things and when I travel it becomes even more important. I find it ridiculous that apple won't run Flash and Java. If I can't run these I will go back to my laptop.
What you rather unfriendly and DEFINITELY unhelpful people fail to realize is 1) I am still, regrettably, using my laptop BECAUSE the iPad cannot run Flash Player. 2) As a PROFESSIONAL, whose livelihood and safety depend largely on weather and the ability to forecast CORRECTLY, not just with a pretty forecaster or cute comments, I SUBSCRIBE to PAY weather services which are much more accurate and detailed than the Weather Channel and Accuweather which try for mass appeal. SO STOP TELLING MY WHAT SIGHTS I SHOULD USE? After 30 years (20 with Internet) I chose my sites because of their quality. 3) I ASKED A SIMPLE QUESTION. With the exception of one or two answers, all the rest of you chose to attack me and criticize me for not wanting to use HTML5 or whatever garbage Apple chooses t shove in my face.
I could give a rat's &$@ what you think of me. I wanted to know if Apple could work for me and now I know it cannot. For now I will continue to lug my heavy laptop around and I will dedicate more time to researching a
Ight alternative. You APPLE JUNKIES are ridiculous. If somebody is unhappy with anything Apple, it is never Apple's fault. OK you run out and buy whatever you are TOLD. I for one choose to buy what works for me. I bout the iPad because everyone raved about how great it was - well, I found out that wasn't true.. in the few months I have owned it I have encountered MANY people unhappy with it for various reasons. YES IT WAS MY FAULT I PURCHASED IT WITHOUT SUFFICIENT RESEARCH--- I WON'T MAKE THAT MISTAKE AGAIN.
All you know-it-alls, can have your junk. I am happy with myself and when I make a mistake I recognize it and change it. I am doing that. I have no use for any of you. you are no help to anyone. Fortunately, I can go back to wonderful life out on the ocean, being paid for what most of you can only dream about doing even once. you on the other hand can go back to your litle cubiclels taking whatever corporate America shoves down your throat and believing it is best for you.
LASTLY, how is it that anyone who has a complaint is a troll? Do you all work for Apple? Or ar you just THAT BRAINWASHED? how lame a life you must have.
