Errors decoding Menus

I made a movie in IMOVIE that is about 90min long. It has about 6 chapters and I exported it to media browser and then uploaded it into IDVD and attempted to burn it to a DVD. After about 10 min. I get an error message stating that the burning was stopped due to errors in encoding the chapters and menus.
Two Questions 1.) Why does this continue to happen?? 2.)I'm just trying to burn a DVD that will play in a DVD player. Any advice on how to do that?? (I've burned this movie already by exporting it to quicktime and burning a DVD, but it only plays in computers and DVD players don't recognize the CD)
Thanks for any advice/Help

90 min may be too long for a DVD if you do not have the settings right.
Also if you are low on disc space on your Hard Drive iDVD will fail.
You need at least 25GB free on your Hard Drive.
In iDVD go to the Project Menu and select Project Info...
You can see if you have a project that is too big for a DVD.
You can change the settings here, try changing the Encoding option, as it affects the time that can be held on a DVD.

Exception: Error decoding message (Key cannot be null)

Hi guys,
     Coherence 3.3.1/389
     .Net API 3.3.1.2
     I've wrote small invocation task, which collects the info about cluster members, stores it to HashMap and return it as result. This is the code:
     NamedCache cache = CacheFactory.getCache(sCacheName);
     CacheService service = cache.getCacheService();
     Cluster cluster = service.getCluster();
     HashMap res = new HashMap();
     Set members = cluster.getMemberSet();
     Iterator iter = members.iterator();
     while(iter.hasNext())
     Member member = (Member)iter.next();
     res.put((Object)member.getProcessName(), new Integer(member.getPort()));
     As you can see if member.getProcessName() returns null, then null is placed to HashMap.
     When the result was returned to the client, I've got this exception:

How can I eliminate (watch) in videos that read "ERROR: DECODE ERROR"?

Usually when in a web site (like Fox News) & there's a video to watch I can't watch it due to the message "ERROR: DECODE ERROR". How can I eliminate this & watch the video? Thanks for your input.

Have you tried to reinstall Flash on your system, uninstall from the control panel, then install from get.adobe.com/flashplayer/‎ and try the video again.

JavaScript error in menus.xml

I'm working with DW 8, and some template files created in DW
MX2004.Has anyone experienced the following error when closing old
template files?
While executing DWMenu_File_Close command in menus.xml, the
following JavaScript error(s) occurred:
Exception thrown in native function.
I've gotten a similar error before, but it had to do with
imbedding library items inside template pages. But, all of those
had been created in DW MX2004. Any ideas?

You can find anything you want on these forums or on the
internet. The
question is - is it credible. This one is not.
What extensions do you have installed?

Complie Error for menus (Swing)

I'm receiving the following complie error. Also, listed is the area for code that is getting the error.
Thank you for any help that you can provide.
Error Message:
P5AWT should be declared abstract; it does not define menuSelected(javax.swing.event.MenuEvent) in P5AWT

ta = new JTextArea(20, 60);
p3.add(ta);
setLayout(new FlowLayout(FlowLayout.CENTER)); // this overides everything, why?
add(p3);
}

menuSelected is a Abstract method. That means if you implement the MenuListener Class you SHOULD define the menuSelected() event.
I am not correct with the Method names but logically it seems that tis is the problem.
Another thing, use setJMenuBar() instead setMenuBar()

Adding an animation causes an error in menus

All - any help would be appreciated.
The minute I add an animation from the library, such as a
flashing arrow, all of my drop-down menus in Captivate are
unusable. Example: I add an arrow animation, then go to "File", the
drop-down menu flashes then goes away, not allowing me to select
anything under it. It happens anywhere there is a drop-down. If I
right-click, the drop-down appears then flashes away. I can click
the Save button to save it, then I have to re-open the project and
the menus work fine....until I add another animation.
THoughts??
Thanks...
Erika

Just found a similar thread on the Import section of this
forum
If you click on an item in the library, Captivate seems to go
back to 'normal' and you can click on the pulldowns

Errors decoding videos from other sessions

Hi
i am studying in a film school over in france, adobe suite 5.5 in french, no plug ins as is, on Lion 10.7 running on a iMac i5 4 GB ram, 2TB HD,
Now where iam staying i use a iMac i7 2.93 ghz from 2010 with 12GB ram and a 2TB drive but runing on 10.6.8 osx, problem is i cqn not open the sessions from school, i get all these erro like the videos could not be decompressed.
or no sequence errors like this
no offense to anyone french but i tried asking the school and they had no clue, it seems they teach directly out of a Lynda.com tutorial and the class mates dont want to hear anything i have to offer unless i explain it in french, to give you an example, the price of the school could pay for a trip to the US, rent, food for 3 months, a english course, the Lynda.com Premiere DVD, a Canon 5Dmkii along aith a nice L lense but i guess its more important to them not to learn english., sorry if i sound like im ranting, this is been going on for a week now.

Make sure you have the latest updates.
Mac is on 5.5.2
http://www.adobe.com/support/downloads/product.jsp?product=98&platform=Macintosh
Im on windows but here is a screenshot of my new sequence options. Make sure you have the same. Im not sure if Mac is different.
If presets are missing then that would explain the missing codecs.

XML to Forms conversion gives error for menus

We are trying the ORACLE <---> XML conversion Utility.
We want to convert a MMB to XML and store it in our repository. When we want to modify it we get the XML from the repository, convert it back to a MMB and edit it. This saves space in the repository DB.
Problem when we convert or MMB --> XML using like this frmf2xml.bat OVERWRITE=YES TRANS_MENU.mmb
the XML file is created.
Now when we try to convert the XML back to a MMB using this code frmxml2f OVERWRITE=YES PRINTTREE=YES USERID=userid/pwd@db TRANS_MENU_mmb.xml we get this error:
Oracle Forms 10.1.2 XML to Forms Tool

Invalid XML - file TRANS_MENU_mmb.xml does not validate against Forms XML Schema:
Invalid value 'INTERNATIONAL_OUT_GOING_CALL_D_MENU' for attribute: 'Name'
I found the problem. For submenus the XML adds a _MENU to the end of the name attribute and when the name of the menu is over 26 chars 26+5 = 31 becomes more than 30 characters. So when the XML is converted to the MMB we get an error because forms objects cannot have names of lengths > 30.
I think this could be a bug. We cannot modify the menu just for this since it is not practical.
Is this a known bug? Any workaround?

Hi Amol,
You XML structure contains deep levels. As far as i understand about the StrictXML2PlainBean module, this is not capable of handling deep structures.
This module is just an alternative to use FCC type functionality for other receiver adapters.
Please take a look at these links:
https://help.sap.com/saphelp_nwpi711/helpdata/EN/44/748d595dab6fb5e10000000a155369/content.htm
StrictXml2PlainBean - to have an XML - EDI conversion?
In case you want to achieve nested level content conversion, you may try this:
/people/karthiknarayan.kesavan2/blog/2007/08/22/file-content-conversion-for-multi-hierarchical-structure
I hope this helps.

Encfs filename decoding error (mounting works, mountpoint is empty)

Hi!
a fairly large (1.9 GB) encfs-encrypted directory of mine stopped working some time ago, and I am hoping someone here can help me regain access to the data.
This is the situation:
– The directory can still be mounted, but the mount directory appears empty.
– The encrypted data seems to be intact: There is a ".encfs6.xml" and a hierarchy of gibberish-named files and folders, which amount to 1.9 GB altogether.
– I can still write to the directory. (I. e. if I mount the dir, create file with "touch <file>", unmount, and remount again, the newly created file is still there.)
– When I run encfs with the "-vf" options, I see these error messages:
20:42:00 (DirNode.cpp:132) error decoding filename: be1k7L8fVkv63EsbHLLxoJtY
20:42:00 (DirNode.cpp:132) error decoding filename: .encfs6.xml
– When I do "ls" on the dir, the command works, while "encfs -vf" says:
20:57:09 (encfs.cpp:92) getxattr /home/carlos/mnt/ssh/morrigan/home/carlos/gemein/encfs/eZAORCDpP7ZyvSscCPZLuUwI
20:57:09 (encfs.cpp:99) getxattr error: Operation not supported
The full output of "encfs -vf" is quoted below. You may notice the the encrypted data is accessed through an sshfs mount. This is not the present source of the problem, as I can reproduce it directly on the server. It may, however, be its origin: The data could have been corrupted by a network interruption (or so I imagine).
There is a similar problem report on askubuntu. It is even from around the same time when it hit me (roughly two months ago):
http://askubuntu.com/questions/360847/e … g-the-data
Also, there apparently was a bug in the boost libraries in 2010 which produced similar errors (among others), but which does not seem to be connected in any way:
https://bbs.archlinux.org/viewtopic.php?id=92209
Any ideas?

Edit: I have by now resigned myself to the fact that the file .encfs6.xml must have been corrupted somehow, which means that the data are unrecoverably lost. Lesson learned: Backups are extra-important for encrypted data!

You can implement this by writing the module to throw an exception or whatever method you want to execute.
If you don't want to receive an error message then module is suitable for you.

This works on WinXP but not Linux. Why? It takes the first frame of an animated gif and writes a thumbnail.
            GifDecoder d = new GifDecoder();
            try {
                fis = new FileInputStream(file);
                bis = new BufferedInputStream(fis);
                log.debug("reading gif");
                d.read(bis);
                log.debug("reading framecount");
                int n = d.getFrameCount();
                log.debug("read framecount" + n);
                for (int i = 0; i < 1; i++) {
                    BufferedImage frame = d.getFrame(i); // frame i
                    int t = d.getDelay(i); // display duration of frame in milliseconds
                    log.debug("resizing frame");
                        File gifoutputfile = new File("gif" + i + outputthumbFilename);
                    BufferedImage bdest = new BufferedImage(60, 60, BufferedImage.TYPE_INT_RGB);
                    Graphics2D g = bdest.createGraphics();
                    AffineTransform at = AffineTransform.getScaleInstance((double) 60 / frame.getWidth(), (double) 60 / frame.getHeight());
                    g.drawRenderedImage(frame, at);
                    ImageIO.setUseCache(false);
                    ImageIO.write(bdest, "GIF", new File(outputthumbFilename));

How is it failing on Linux? Wrong results? What are they? Error messages? What do they say? You need to give us some place to start looking.
