Basing on the log entries:
262839 [atomic-processor-1] INFO com.github.sarxos.webcam.ds.cgt.WebcamOpenTask - Opening webcam A4 TECH USB2.0 PC Camera J /dev/video0
270023 [webcam-discovery-service] INFO com.github.sarxos.webcam.Webcam - Disposing webcam A4 TECH USB2.0 PC Camera J /dev/video0
270079 [AWT-EventQueue-0] WARN com.github.sarxos.webcam.Webcam - Cannot get image, webcam has been already disposed
Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: image == null!
...We can conclude that the error is thrown because webcam has been already disposed before taking image. Can you share some source code?
Dependencies in your POM seems to be incorrect because you are using both bridj v0.7 SNAPSHOT inherited from webcam-capture 0.3.10 RC6 and bridj v0.6 SNAPSHOT from your dependency. This should rather be:
<dependency>
<groupId>com.github.sarxos</groupId>
<artifactId>webcam-capture</artifactId>
<version>0.3.10-RC6</version>
<exclusions>
<exclusion>
<groupId>com.nativelibs4java</groupId>
<artifactId>bridj</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.6.1</version>
</dependency>
<dependency>
<groupId>com.nativelibs4java</groupId>
<artifactId>bridj</artifactId>
<version>0.6.3-SNAPSHOT</version>
</dependency>It would be good to share complete debug output:

In case of debug logs, please replace slf4j-simple with logback.

Hello there,
I've been struggling with library for a while, most of my problems were solved by responses to other issues, but now I'm stuck at the dead end. After starting my jar, I see that USB came is detected. After it is supposedly opened, but disposed a moment later. (And I receive error that image that I try to save is null).
Here is an error I've been receiving
Got openjdk-7-jre on my Raspberry PI with Rasbian OS. Using default driver. No .so files outside the jar.
Party of my used dependencies
How can I overcome this issue ? Is there any confirmed way to make it run on Rasbian OS?
Thanks in advance for Your help :)
