sarxos / webcam-capture

The goal of this project is to allow integrated or USB-connected webcams to be accessed directly from Java. Using provided libraries users are able to read camera images and detect motion. Main project consist of several sub projects - the root one, which contains required classes, build-in webcam driver compatible with Windows, Linux and Mac OS, which can stream images as fast as your camera can serve them (up to 50 FPS). Main project can be used standalone, but user is able to replace build-in driver with different one - such as OpenIMAJ, GStreamer, V4L4j, JMF, LTI-CIVIL, FMJ, etc.

Could Not Initialize OpenIMAJGrabber #799

Open jhess32259 opened 3 years ago

jhess32259 commented 3 years ago

Greetings, @sarxos.

I'm receiving an exception when instantiating a JPanel form. Environment is NetBeans 12.1 with OpenJDK15. Below is the code to the JPanel, the exception text, and the POM. Any help would be greatly appreciated.

Regards, Joe Hess

JPanel Code

package sst01;

    webcam = Webcam.getDefault();

I'm getting the exact ( almost ) same error on my logger server

I can't replicate this on my machine but some of my clients are getting this POM: webcam-capture 0.3.12

Hi @farshidmh, I am not sure what is your OS, linux x86 arm? it looks OpenIMAJ precompiled native. i.e. JNI is not supporred by your OS. natives are not resolved.

com.github.sarxos.webcam.ds.buildin.natives.OpenIMAJGrabber.

Please set up log level to DEBUG and share your detailed log.

farshidmh commented 3 years ago

@alexmao86

users OS is mostly Windows 7,8 or 10 (both x86 and x64) and the application is delivered with bundled JRE (1.8).

It gets worse, camera may work today but stops working tomorrow!

alexmao86 commented 3 years ago

Hi @farshidmh, The biggest challenge is reproduce the issue. For windows, openIMAG definitely supported, besides windows, linux, arm, armhf...are supported.

"Caused by: java.lang.NoClassDefFoundError: Could not initialize class" no means class not in classpath, really reason is the static block of lading JNI failed.

so questions are:

regarding stops for long time running, a bells ring in head is that we will review if any thread safe issue that open/close session not in pair causing potential leak issue. we will check.

farshidmh commented 3 years ago

Hi @alexmao86

I'm using maven 0.3.12, it will install bridj 0.7.0

`

com.github.sarxos webcam-capture 0.3.12

`

As I mentioned we are using 1.8 thus javafx is builtin
