picam bridj error dlopen error

[SynGreis]

I ran this exact jar on my windows machine and laptop that contains raspbian as its OS. works great.

But when i put this on the rpi and use nothing but the picam i get these errors...

Is this looking for a different bridj and does this sarxos webcam library work with the picam? I really got attached to this library and would prefer not to go to another api if it can handle the picam.

Hi @SynGreis,

Sorry for late response. I was on a vacation whole August and I simply missed this issue. Did you try to replace BridJ version?

[sarxos]

@SynGreis,

I see the problem. You are missing libjpeg on your RasPi.

This should solve the problem:

sudo apt-get install libjpeg

[SynGreis]

tried it, says unable to locate package

[sarxos]

Try with libjpeg8.

i was able to download and install fine. Unfortunately it still doesnt detect my camera is there. No errors that would halt the program but it thinks there is no camera.

`List list = Webcam.getWebcams();

            if (list.size() > 0) {

                MainPage.CamStatus = true;

                lblCamR.setText("<html><font color='009900'>Connected!</font></html>");

            } else {

                Refund.bool = false;

                MainPage.CamStatus = false;

                lblCamR.setText("<html><font color='990000'>Disconnected!</font></html>");

            }`

I am unsure if this is the method used for the picam as it isnt USB.

[sarxos]

Oh, it won't work out-of-the-box if your device is not UVC (USB Video Class).

In case you have a camera module you may try this:

i did

$ sudo modprobe bcm2835-v4l2

but it couldnt find the directory at all. what would be the install command line for this? I suspect im missing a few installations.
