Current javacv crashes with example provided in javacv homepage about javacv HOT 27 CLOSED

Same problem using Vista 64 bits with 64 bits Java RE/SDK and Eclipse Helios 64 
bits.

OpenCV binaries are not provided with 64 bits version. So I guess we have to 
compile them for our environment.

As patem mentions, can you confirm that you are running a 64-bit version of 
Java _and_ a 64-bit version of OpenCV, *OR* a 32-bit version of Java _and_ a 
32-bit version of OpenCV? i.e.: You are not trying to mix modules of different 
bitness?

Hm interesting, I'm actually using Java 32 bits, and if OpenCV comes only in 32 
bits, then everything is in 32 bits, but my actual Windows 7 machine is 64 
bits..

Update: I reinstalled OpenCV binaries (2.2, I was using 2.1 previously), and 
that solved that part of the problem! maybe the 2.1 binaries did include 64 
bits? older javacv with older opencv were working fine on this machine! no 
idea, but that did the job.

So, now everything is on Windows 7 64 bits, but my java and opencv are 32 bits. 
However it crashes runtime after defining the OpenCVFrameRecorder, when I call 
recorder.start():

Also, if I use FFmpegFrameRecorder instead, I get:
Exception in thread "main" java.lang.UnsatisfiedLinkError: 
com.googlecode.javacv.cpp.avcodec$AVPacket.allocate()V
        at com.googlecode.javacv.cpp.avcodec$AVPacket.allocate(Native Method)

        at com.googlecode.javacv.FFmpegFrameRecorder.<init>(FFmpegFrameRecorder.java:101)
        at javacvvidrec.Demo.main(Demo.java:76)

So it seems I can't use neither OpenCVFrameRecorder nor FFmpegFrameRecorder for 
some reason..

Ah, it seems the precompiled highgui of OpenCV 2.2 does not work with the 
"CV_FOURCC_DEFAULT", but it works with "-1", so I guess I will change the 
default in the next release of JavaCV.. for now, you can work around that by 
putting this line before "recorder.start()":
        recorder.setCodecID(-1); 

To use FFmpeg, you first need to install FFmpeg, as explained in the README.txt 
file.

great, thanks. I'll try it out today and see how it goes.
As of FFmpeg, what I can say is I used the binaries from 
http://ffmpeg.arrozcru.org/autobuilds/
I tried different versions (32 bits, 64 bits, shared and static), and it seemed 
to have installed fine, since I could run ffmpeg command from the command line, 
but I would still be unable to run FFmpegFrameRecorder. 
However, if this might be a solution, I can try to compile ffmpeg myself 
(cygwin, MinGW, MSYS, etc) on 32 bits I imagine, making sure I also have LAME 
installed, and see if that solves the issue..

Update 1:
I tried setCodecID(-1). I also tried CV_FOURCC_PROMPT, but still no success. 
However, the problem is different now: it doesn't crash as earlier, but it just 
seems to be stuck in an infinite loop somewhere: the programme does not 
terminate, does not crash, does not indicate any error at any moment, but after 
running the line recorder.start() it just stays there. Exploring it further, it 
seems to stop more specifically at:
writer = cvCreateVideoWriter(filename, codecID, frameRate, cvSize(imageWidth, 
imageHeight), pixelFormat);
Have you tried that line with opencv version 2.2, using codecID=-1 or so?

As a side note question: what is the fps that I can get with javacv for mac, 
windows and linux? what order of magnitud slower than opencv?

The problem with FFmpegFrameRecorder might have to do with some issues I'm 
having with JavaCPP not being able to automatically load libraries sometimes. 
Calling
    Loader.load(avformat.class);
before trying to use the FFmpeg classes may help.

As for cvCreateVideoWriter(), yes setCodecID(-1) works just fine here with 
either 32-bit or 64-bit Windows. If it does not work for you, I suggest you ask 
the OpenCV guys to fix it.

Whatever FPS OpenCV and FFmpeg support for the given format.

Hi the same error here. My code:

    File f = new File("d:\\videok.avi");
    OpenCVFrameGrabber grabber = new OpenCVFrameGrabber(f);
    try {

        grabber.start();
        cf.showImage(grabber.grab());
        grabber.stop();
    } catch (Exception e) {
    }


grabber.start() throw:

Java Result: 1
BUILD SUCCESSFUL (total time: 1 second)

After this i tried: FFMpegFrameGrabber :
i got this when try to  "new FFMpegFrameGrabber(f)"

windows 7 64bit, java 32 bit.

now a i try the same in windos xp mode... maybeee

Some people are having problems using OpenCV to capture Windows 7:
http://groups.google.com/group/javacv/browse_thread/thread/418cec93c72143a7/fc17
e84fedaa77f2#38847e69646e50f2
Either downgrade to Windows XP, ask the OpenCV guys to fix this, or use 
something else to capture images

Latest version of JavaCV now uses `CV_FOURCC_PROMPT` under Windows, which fixes 
the crash

The same issue still prevails in android

Well, if you could provide more details I may be able to actually do something 
about it, because this works fine on Android for me:
http://code.google.com/p/javacv/downloads/detail?name=facepreview-20110407.apk
So there is nothing wrong that I can see.

well, i don't know if my issue is similar to any above. I keep getting the 
error "cvCreateVideoWriter(): Could not create a writer", i have only attempted 
this in android and none of the ideas on the internet have helped.
Further more, when i attempt to use FFmpegFrameRecorder  to record my output it 
simply crashes on initialization.
What could i be doing wrong?

If you read the README.txt file, you will understand that I compiled OpenCV 
without support for FFmpeg, so there is no reason for OpenCVFrameRecorder to 
work. 

To use FFmpegFrameRecorder, you need the libraries of FFmpeg. Please read the 
README.txt file. thank you

Thanks for the quick response, when you said "To use FFmpegFrameRecorder, you 
need the libraries of FFmpeg" did you mean the precompiled libs for ffmpeg arm 
which were to be placed inside the /libs/armeabi/ folder?

Yes... Can you please post your questions on the mailing list? Your questions 
are totally unrelated to this issue, and besides this is not an issue to start 
with

Ok thanks, i'll do that, but i just have to mention that i followed 
instructions on the quick start for opencv to the letter and the demo simply 
did not work on android 2.2.

 I am Chinese, my Englist is bad.  The eclipse of how to solve this problem?

i also get the "unsatisfiedLinkError blablabla can't find dependent libraries"

work at all, what should i do.

Hi,

      When I have run my eclipse java application i got Error like :Exception in thread "Thread-7" java.lang.NoClassDefFoundError: Could not initialize class com.googlecode.javacv.cpp.avcodec$AVPacket

I have download opencv OpenCV 2.4.8 ,Javacv-bin-0.7 , FFmpeg Share Latest 
version windows 64 bit ,also i have configure Environment System Variable class 
path Configure Javacv jar ,javacpp jar ,javacv_windows.jar, and Path set FFmpeg 
bin folder , and opencv all bin , lib and static folder set .Any mistake let me 
.Thanks

@sameer Please try the FFmpeg binaries provided here:
http://javacv.googlecode.com/files/javacv-0.7-cppjars.zip
instead of "FFmpeg Share Latest version windows 64 bit".

And please ask your questions on the mailing list if possible, not here, thank 
you.

Ok Next Time I will ask my mail listing ,Thanks For reply to me ,I have 
download Zip file , here ffmpeg-2.1.1-windows-x86_64 and 
ffmpeg-2.1.1-windows-x86 , can i have configure Environmental System Path ? 
please let me know clear idea.

Thanks Samuel

@sameer Please follow the instructions in the README.txt file. If you do not
