GSVideo + Proclipsing / Eclipse

in Contributed Library Questions • 3 years ago

Hey,

I'm having trouble getting GSVideo to work in Eclipse. It works perfectly if I run the example codes in Processing.

I'm getting the error:

Exception in thread "Animation Thread" java.lang.NoClassDefFoundError: com/sun/jna/Platform

My main class is called GSCap and I'm running Mac OS X 10.6.4.

Any clues why this isn't working?

Thanks!

Oh, and I've tried

GSVideo-Mac-SnowLeopard-0.7.zip

GSVideo-Mac-SnowLeopard64-0.7.zip

GSVideo-Mac-Leopard-0.7.zip

GSVideo-Mac-Leopard64-0.7.zip

All libraries give the same error.

Sorry I just spotted your question.

It seems you are missing jna.jar. Add it in Properties|Java Build Path|Libraries (by choosing "add external jar" and then browsing to GSVideo/libarary and picking jna.jar from there)

Re: GSVideo + Proclipsing / Eclipse

That worked! Almost. :)

Now I get a different error message, I've googled it and found out that it may not run on Snow Leopard according to some post you made a year ago, but is that fixed now?

Re: GSVideo + Proclipsing / Eclipse

Many of the previous problems with OSX are "more or less" solved by now

About the error in Eclipse, it seems that you are not specifying correctly the location of the libraries. You have to add to the project the jars that come inside GSVideo/library (GSVideo.jar, gstreamer-java.jar, as well as jna.jar), you do this also in Properties|Java Build Path|Libraries

Re: GSVideo + Proclipsing / Eclipse

Yeah I figured I should add gstreamer-java.jar and GSVideo.jar to the build path but I still get the same error.

It seems like it's not including the dylib files inside the GSVideo/library/gstreamer/macosx/. Any way I can do that?

Thanks for your quick response!

Best,

Jonas

Re: GSVideo + Proclipsing / Eclipse

Okay, apparently Proclipsing copies the jar's to the project, so if I removed those that Proclipsing includes and add them from the Processing/library/ folder I get a different error:

Re: GSVideo + Proclipsing / Eclipse

If you are using the 64 bits version of GSVideo, then unfortunately capture won't work since it depends on a gstreamer plugin (osxvideosrc) which is still not compatible with 64 bits OSX.

Re: GSVideo + Proclipsing / Eclipse

3 years ago

Aha, well I have no need to run it in 64 bit, so I changed Java Preferences to 32 bit and downloaded the 32 bit version of GSVideo and now I'm getting a new error - Doh.

This, well, I have no clue why.

Re: GSVideo + Proclipsing / Eclipse

To tell you the truth, I'm not sure what could be the reason of the problem.

But my own experience with Eclipse is the following: I'm using OSX 10.6.4 64 bits, and have both the 1.6 and 1.5 JDKs installed on it (I used the instructions here to install 1.5, which doesn't come by default with Snow Leopard). If I try using gsvideo for leopard (32 bits), with the 1.5 JDK, the app runs fine. If I choose the 1.6 JDK, then it crashes complaining about wrong architecture dylib. On the other hand, if I use gsvideo for leopard, 64 bits version, the results are reversed: the app crashes with JDK 1.5 and runs fine with 1.6.

Re: GSVideo + Proclipsing / Eclipse

Nope, not yet. I'm using 10.6.4 Snow Leopard and I've tried the 1.5 JDK 32 bit with GSVideo Leopard 32 bit and 1.5 JDK 64 bit with GSVideo Leopard 64 bit.

And of course tried all the different libraries for 1.6 JDK, both 32/64 bit.

Any clues? :)

Hey guys,

i am stuck with the same problem here....

- 10.6.4 Snow Leopard

- 1.6 JRE

although I am not entirely sure which GSVideo Library is the optimal one to use... any clues? Here is the error that i get:

Re: GSVideo + Proclipsing / Eclipse

Right now I'm not sure why gsvideo is crashing like this in Eclipse.

I'll look at this issue more carefully during the next weeks.

JMCVideo and OpenCV libs provide playback and capture, you could use these instead.

Re: GSVideo + Proclipsing / Eclipse

Thank you for the reply.

To tell you the truth, I am quite confused by now, since I have taken some different routes at installing the library because of these 32-64 bit apple vs java issues...

Here is what I can recall doing.

1. Downloaded this GSVideo library http://sourceforge.net/projects/gsvideo/ which is the GSVideo-Mac-Leopard64-0.7.zip file.

I presume this is the 64bit.

2. Inserted the folder into the Processing.app/Contents/Resources/Java/libraries/GSVideo

3. In my project folder in Eclipse i imported the following jars:

- gstreamer-java.jar

- GSVideo.jar

- jna.jar

- (plus, of course the mandatory core.jar)

and added them to Build Path, and trying to export this project I ended up with the abovementioned exception. I googled it, and got more confused, so I tried the 32-bit and same result as earlier. I also ended up installing the Gstreamer dmg file that was linked from your site http://codeanticode.wordpress.com/2009/04/03/gstreamer-installer-for-macosx/ and now, I dont know how to uninstall it because I cant use the PDE because I get this exception:

[0] "dyld: lazy symbol binding failed: Symbol not found: _iconv_open"

[1] " Referenced from: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Libraries/../Libraries/libnpt.jnilib"

if i export the sketch into a browser it loads fine, but not from the PDE it self....

So after reading further on the site, I saw that I had to delete the Library/Gstreamer folder, which I did, and also edit the launch.conf file - this file I have no clue what it is because I do not have it anywhere on my system... ? But all in all, i deleted the folder, and still the same errorr...

But any thoughts to how I can solve the uninstall of the GStreamer to make the PDE working again?

All i want is basically to load a mov or avi file with the help of the GSVideo library..... :-)

Ok, so I downloaded the latest GSVideo bundle I could find (which I found here: http://codeanticode.wordpress.com/2010/08/22/gsvideo-0-7/ )

and here is my new exception from Eclipse:

Any suggestions to what I can do?? Seems that this is a conflict with the PDE.

Re: GSVideo + Proclipsing / Eclipse

i'm stuck on exactly the same errors listed above, trying to capture with GSVideo (GSCapture).
specifically:

Exception in thread "Animation Thread" java.lang.UnsatisfiedLinkError: Unable to load library 'gstreamer-0.10': dlopen(libgstreamer-0.10.dylib, 9): image not found

with osx 10.6.7 + eclipse 3.6.2 + JVM 1.5 + Processing 1.2.1.

i can change things around, if there's an optimal setup for using GSCapture with eclipse...have we found a working setup?
thanks!

Hi, I think the discussion in this thread should help.

Re: GSVideo + Proclipsing / Eclipse

thanks andres. that thread got me going with GSMovie, but not yet with GSCapture -- i see from this thread that i need to move down to the 32-bit version of GSVideo to use GSCapture (i'm getting the osxvideosrc error now).

i haven't tried swapping the 32-bit GSVideo into the project provided by jonobr1 on the other thread; that's the next step. i'll report back when i have a chance to test that.

Re: GSVideo + Proclipsing / Eclipse

Hi All

I think I had a similar problem which I resolved in the following way:

I created a processing project using proclipsing, selecting gsvideo.

Then I copied the "gstreamer" folder from:

<processingSketchPath>\libraries\GSVideo\library\

<workspace>\<projectName>\lib\user\GSVideo\

Then I went into the Properties of the project and under "Java Build Path", "Add External JARs..." selected

<processingSketchPath>\libraries\GSVideo\library\jna.jar

And now GSvideo works!

I have tested this on Windows so far but it should work on all OSs. I will test on GNU/Linux shortly.
