Frequently Asked Questions & Troubleshooting

The questions below try to address some of the things you might encounter. If you have any other problems with USING the software, please add them via the comments below. If you have specific questions about RECODING, please see the development notes and use the feedback mechanism mentioned there. Thanks a lot!

App doesn't start

Most likely cause is the lack of a suitable Java runtime environment on your machine. Did you read the requirements & installation instructions? Another cause might be insufficient RAM available to launch. The app initially tries to reserve at least 128MB of RAM and usage can grow up to 640MB when exporting high resolution assets (by default, can be edited via run.bat/run.sh files or editing the info.plist file for the OSX version)

App launches but my graphics look different than the official images

Most likely your graphics card does not support all the required features and so you're seeing the fallback version using only a single colour for each mesh layer. In order to recreate the original look, your graphics hardware needs to support OpenGL Vertex & Pixel Shaders.

App doesn't fill the screen

The downloadable application is by default set to a 1280x720 screen resolution and to change the size you'll have to edit the configuration file. Then try again with the new settings.

App is running, but very sluggish (< 5fps)

During the exporting of an image sequence, the application will be running much slower than normal since each frame has to be saved to disk. If performance is sluggish when not exporting, then this is most likely caused by insufficient RAM causing your system to repeatedly swap virtual memory from disk: http://en.wikipedia.org/wiki/Paging. Try editing the RAM settings (see above) and close all other applications.

App freezes when trying to export high res assets

Again, this is probably a RAM issue because the app can't reserve enough memory for the high res image. Make sure your machine satisfies the minimum hardware requirements or try closing other applications before restarting the V&ADecode application. In the default configuration (1280x720 and export tiles = 10) the app will require approx. 560MB of RAM when exporting.

I edited the config file, but app is not working anymore

You'd better kept a backup of the original file. If not, simply download the app again.

I have installed the latest java runtime (Java 6 Update 17 ) but when I try to run the run.bat file I get an error " 'java' is not recognised as an internal or external command, operable program or batch file " I am currently running windows 7 and my system meets all the specifications for the program to run. How can I fix this?

I have installed the latest java runtime (Java 6 Update 17 ) but when I try to run the run.bat file I get the following in a command window:

Plus a blank 1280x720 window.

The operating system is Windows 7

Sorry for the late reply, these comments have slipped through my net so far...

@David the error you're getting means your graphics hardware/card is not supporting a fairly standard feature to deal with 3D geometry. This might either have to do with the hardware directly, insufficient drivers or an incompatibility with Windows 7. It's 100% not a Java issue...

@timisapig your problem seems to be a corrupted PATH environment variable, which again has nothing to do with Java per se, but is a sometimes occuring problems with all versions of Windows. You'll need to manually fix this PATH variable by adding the location of the Java installation folder via the Windows system control panel.

Hello. I think I've got a 64bit problem: "Exception in thread "Animation Thread" java.lang.UnsatisfiedLinkError?: C:\webpub\decode\lib\jogl.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform"

Is there any thing I can do about this?

Chers,

Elliot

Yes doesn't seem to like 64bit windows and thinks I'm AMD, but I'm intel. maybe Sun's fault!?
