Current javacv crashes with example provided in javacv homepage #49

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Install all prerequired software as instructed in the website
2. Create a java project and add the Demo.java example provided in the javacv 
homepage
3. Add all the javacv jar libraries (Netbeans)
4. Run/Debug the project -> it crashes at Loader.load(opencv_objdetect.class);

What is the expected output? What do you see instead?
Not to crash. I have everything installed, I have tried older versions in the 
past that run on this machine (when it used name.audet.samuel.javacv.jna... 
instead of com.googlecode.javacv.cpp...
(by the way, notice the missing semi-colon at line "import 
com.googlecode.javacv.cpp.*" if you would like to correct it

What version of the product are you using? On what operating system?
Latest version, downloaded today. Windows 7. However, it seems to run fine on a 
Mac, but that the video recorded seems to be wrongly encoded and looks very odd 
(but I guess this is a separate issue I can open in another thread).

Please provide any additional information below.
It compiles fine, but it crashes at:
Loader.load(opencv_objdetect.class);

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.

Original comment by patem...@gmail.com on 23 Feb 2011 at 9:50

GoogleCodeExporter commented 9 years ago 
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():

# The crash happened outside the Java Virtual Machine in native code.
# See problematic frame for where to report the bug.
#

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 javacvvidrec.Demo.main(Demo.java:76)

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

GoogleCodeExporter commented 9 years ago 
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.

GoogleCodeExporter commented 9 years ago 
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?

Original comment by steve.ro...@gmail.com on 26 Feb 2011 at 12:51

GoogleCodeExporter commented 9 years ago 
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:

After this i tried: FFMpegFrameGrabber :

something else to capture images

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

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?

Original comment by pbb...@gmail.com on 19 Jun 2011 at 2:49

GoogleCodeExporter commented 9 years ago 
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?
