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.

Unexpected exit #545

Hi,

I'm using IPCamera and have setup a motion detection listener to capture images from stream and upload them to AWS S3.

I'm using Maven dependencies as below:

<dependency>
      <groupId>com.github.sarxos</groupId>
      <artifactId>webcam-capture</artifactId>
      <version>0.3.11</version>
</dependency>
<dependency>
        <groupId>com.github.sarxos</groupId>
        <artifactId>webcam-capture-driver-ipcam</artifactId>
        <version>0.3.11</version>
</dependency>

My application is stopping unexpectedly after a few minutes with the following error:

[webcam-panel-scheduled-executor-1] ERROR com.github.sarxos.webcam.WebcamExceptionHandler - Exception in thread webcam-panel-scheduled-executor-1

Any help is much appreciated.

I think this is because in IpCamDevice connection is not renewed after error. This can be fixed, but I have no much time to work on this.

rajesh-rt commented 6 years ago

sarxos, could you tell me how can I fix this? I'm using an ip camera(HIKVISION DS-2CD2420F-I(Audio) 2MP IR Cube IP Camera) connected over wifi. I'm facing this issue whenever I want to access video stream of an ip camera. Earlier I used Logitecth HD webcam and hadn't faced this issue.

sarxos commented 6 years ago

Sure, you can change try/catch in IpCamDevice.getImagePullMode(..) and add catch for SocketException and instead of returning or throwing exception renew connection to the IP camera.

I will be happy to merge pull request for this if you fix it.

Hi, I encountered the same issue. This time its happening right after capturing an image. I'm using HIKVISION IR Network Cube Camera(DS-2CD2420F-I). Below is the url I used. http://username:password@ip:port/Streaming/channels/ID/picture

@rajesh-rt, I won't be fixing this because I have no access to IP camera I could test this issue with. Feel free to fix this on your own. Please let me know if description I provided in my comment above is not sufficient for you to start working on a solution.
