error in cxcore

[GoogleCodeExporter]

Can you confirm that you are using a 32-bit version of Java?

Hi,

I have a similar problem when trying to run ffmpeg-java. I tried the first 
example of the README file (with the difference I used a local movie file):

java -cp ./ffmpeg-java.jar:./lib/jna.jar 
net.sf.ffmpeg_java.example.PlayerExample test.mov

and got the following error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: Error looking up 
function 'url_read_complete': /usr/lib64/libavformat.so.52.31.0: undefined 
symbol: url_read_complete

I'm running Debian Squeeze 64 bits. I downloaded JNA 3.2.5 from 
https://jna.dev.java.net/servlets/ProjectDocumentList?folderID=12139&expandFolde
r=12139&folderID=7408

Any help would be much appreciated.

Thank you very much,

Adriano

although this might seem a jre problem i have installed several jres and i'm 
sure that it used to work with the same jre...
but it says there is an error in the native code in one site (the site says 
this error might have been caused by native code problem)

please tell me if there is something that i'm missing, i've downloaded opencv 
2.0.0 from source forge, chose the option to add to path for all users..... but 
i still don't know what the problem is.....i'm using 32 bit java on 64 bit 
windows 7.
thank you

Since you are running 32-bit x86, you should try to recompile OpenCV without 
SSE instructions as indicated in the README file. If you choose 64-bit x86 
instead, then you need to compile 64-bit DLLs for OpenCV

As for the FFmpeg, AFAIK neither Debian nor Ubuntu bundle FFmpeg 0.6 yet, only 
0.5.. you will need to install version 0.6 as indicated in the README file

Hi,

Thanks a lot for your reply. You're right; the version of ffmpeg in Debian 
Squeeze right now is 0.5.2. However, although I saw the FFmpeg 0.6 requirement 
on the javacv page, the README file that comes with the ffmpeg-java package 
(file ffmpeg-java-bin-20100405.zip) suggests ffmpeg 0.5. Maybe this needs to be 
updated?

I use OpenCV a lot through its Python wrappers and, at least for now, I was 
mainly interested in ffmpeg-java. My hope is that I would be able to use it in 
Jython in order to read/write media files. I really miss the ability to handle 
media files in Python. PyFFmpeg looks promising, but right now lacks the 
ability to encode videos :-(

Thanks a lot,

Adriano

That's right, I had not updated the README.txt file. I have just released a new 
version with an updated one :) BTW, FFmpeg can easily be compiled from source 
code under Linux.. You just need to make sure the "shared libraries" option is 
enabled..

And yes, I think Jython is a good idea for Python programmers. It supports 
concurrency (via threads), contrarily to CPython.

i confirm my problem was solved after installing the latest opencv vc.
thank you very much

I am running windows 7 ultimate, 64 bit. I also installed the OpenCV 2.1 and 
all the other required software as described in the README. Can some one offer 
any suggestion to rectify the problem.

Kind regards,
A.

Andre, if you are running a 64-bit version of Java, you also need to compile a 
64-bit version of OpenCV. If you are running a 32-bit version of Java, then you 
need a 32-bit version of OpenCV. Make sure they match

Thank you very much, the problem has been resolved.

I am a beginner of OpenCV.
I have the same problem, which Andre faced earlier. 
Could you give me idea how to compile a 64-bit version of OpenCV?

Do I need to reference OpenCV somewhere in the eclipse library?

Kind Regards,
Palupi

Compiling OpenCV correctly depends on your platform. Please refer to the 
documentation of OpenCV.

As explained in the README.txt file, JavaCV looks for OpenCV in a few places, 
the system PATH, most notably.

BTW, if you are having problem using JavaCV, please post messages in the 
discussion group, as I am in theory the only one reading any messages you post 
here, thank you
