How to grab video from IPCamera "Foscam" using JavaCV?

[Issam Laradji]

Dear all,

I have an IPCamera, in particular Foscam, to be connected using JavaCV, I used OpenCVFrameGrabber grabber = new OpenCVFrameGrabber("IP address of Foscam"); but it was in vain, I have also read about using fmmpeg and that made me go through lots of trouble in linking the libraries and .dlls which at the end did not succeed :(. When I put the IP address of the camera in the browser, the video input is displayed, however, I faced lot of difficulties connecting with it using Java or JavaCV. It will be great and appreciated if someone can kindly provide me with a simple guide that resolves this issue. Thank you

Regards,

Yes it should work fine with FFmpegFrameGrabber. What issues do you have
with FFmpeg exactly?

[Issam Laradji]

Well, I am getting this error "java.lang.UnsatisfiedLinkError: C:\Users\Issam\AppData\Local\Temp\jniavutil8825908578221633874.dll: Can't find dependent libraries"

After using this code statement : "FFmpegFrameGrabber grab=new FFmpegFrameGrabber("http://196.15.61.61/videostream.cgi?user=admin&pwd=&resolution=32&rate=6");"

Even though I have put all the required.dll files of FFmpegFrameGrabber such as "avcodec-54.dll" in the System32 folder and added their location to the SYSTEM PATH, yet still did not work :(. I have read about the common problems with openCV but it was not that very helpful. To clarify, I have Windows 7 64-bits. Looking forward for your positive suggestion. Thank you

I suspect (as you do)  there is something wrong with your av install/location.

As a possible different solution I created a IPCamera frame grabber - the source is here

http://code.google.com/p/myrobotlab/source/browse/trunk/myrobotlab/src/org/myrobotlab/image/IPCameraFrameGrabber.java 

and it's been tested with a Foscam camera.

Good luck.

Ah great, I'll have to put a link (at least) to that project, thanks for
letting me know!

[Samuel Audet]

Please try again with the known working binaries, as indicated in the
README.txt file, thank you

[Issam Laradji]

Thank you for the quick and efficient reply :), I will try it and get back to you with the results. Thanks

This link is not working :(

Yes,

It got moved -

Hey, that's nice. Do you feel this and a few others things would be best
moved into JavaCV itself?

[Greg Perry]

Sure, 

There are 5... 

BlockingQueueGrabber.java

ImageFileFrameGrabber.java

IPCameraFrameGrabber.java

PipelineFrameGrabber.java

VideoSourceFrameGrabber.java

But I think BlockingQueueGrabber, ImageFileFrameGrabber, IPCameraFrameGrabber are probably the ones you might consider.

They are pretty simplistic. 

BlockingQueue is nice when your external source is on a different thread.

IPCameraFrameGrabber is for mjpeg - yes not the fastest, but probably the most ubiquitous codec which doesn't need ffmpeg depenencies

and ImageFileFrameGrabber - which provides grabbing the same image repetitively

The rest probably will drag in more dependencies than you want.

Let me know if you do use them, I'd like to remove them from my archive if you release with something comparable.

Sounds good! If you could clean them up to your satisfaction and have
them ready to insert in the com.googlecode.javacpp package, that'd be
great, and I will commit them as is. (BTW, the Google Code Way of
transmitting patches is via the issue page...)

And if you can think of anything else that you would be better off in
JavaCV, bring them along! thanks

Hi, Greg,

Am I to assume that you consider your code to be satisfactory and would
like to include it as is in JavaCV?

Hi all,

Late to the convo... Also looking for the java source code as mentioned above, but the Google Code URL no longer works.  Would anyone have an updated link?

Thanks a bunch,

Frank
