Hi,
Unfortunately, for now there is no possibility to query device capabilities (e.g. supported resolutions), but there is such feature planned - it can be incorporated in 0.4, but cannot give you any details when it will be released. It's a big feature and too few developers are working on this one and related project now, so it will not be available very soon...
However, there is a way to fix your resolution problem. You should use setCustomViewSizes(..) method. It takes Dimension[] array as the argument.
Dimension[] nonStandardResolutions = new Dimension[] {
WebcamResolution.PAL.getSize(), // you can use predefined resolution
WebcamResolution.HD720.getSize(),
new Dimension(2000, 1000), // or custom one
new Dimension(1000, 500),
};
Webcam webcam = Webcam.getDefault();
webcam.setCustomViewSizes(nonStandardResolutions);
webcam.open();
BufferedImage image = webcam.getImage();
System.out.println(image.getWidth() + "x" + image.getHeight());from webcam-capture.

Please reopen if it does not fix your problem.

For the 1280x1024 and 1024x576 you should use this code:
webcam.setCustomViewSizes(new Dimension[] {
WebcamResolution.SXGA.getSize(), // 1280x1024
new Dimension(1024, 576), // PAL depicted for 16:9 widescreen
});from webcam-capture.

1/ the :
Dimension frameSize = new Dimension(1024, 576)
webcam.setCustomViewSizes(new Dimension[] { frameSize });
webcam.setViewSize(frameSize);
BufferedImage img = webcam.getImage();
but:
2/ adding webcam.open() - leads 100% to crash in the JVM
Dimension frameSize = new Dimension(1024, 576)
webcam.setCustomViewSizes(new Dimension[] { frameSize });
webcam.open(); <<<<<-- this one leads to crash
webcam.setViewSize(frameSize);
BufferedImage img = webcam.getImage();

Could you please locate the Java's hs_err_pid file in program working directory (it is created after each crash) and share it via e.g. pastebin.com? It's pretty long, but it contains necessary stack traces from both Java and native code.
The custom resolution feature could lead to some issues, but I would like to check if this is caused by this specific resolution or rather by synchronization issue (native code is not thread-safe and core dump Java process each time when you try to access it from two separate threads).

Could you please repeat this experiment with trace level enabled? I will need console debug output since there are too few information in hs file. Java crashed because code tries to read memory which was already deallocated, so to resolve your issue we have to find why it was deallocated in first place. By enabling trace logs we should be able to see exactly what operations are being executed in the webcam-capture runtime.
Please drop this logback.xml file in the program working directory:
<configuration scan="true" scanPeriod="30 seconds">
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<layout class="ch.qos.logback.classic.PatternLayout">
<Pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</Pattern>
</layout>
</appender>
<root level="trace">
<appender-ref ref="STDOUT" />
</root>
</configuration>And include this line at the very beginning of your main() method (before you try to use any webcam feature):
WebcamLogConfigurator.configure("logback.xml");Please make sure to add logback-classic and logback-core JARs in the build classpath.

Could you also try to test it on smaller code, e.g. on this very simple example, or another more complex one?

not much luck with the trace...

OK the problem seems to be the place where I have put the setVewSize(...) this exact example crashes..
Webcam webcam = Webcam.getDefault();
webcam.open();
webcam.setViewSize(new Dimension(640, 480)); // <---- this where it is in my code in your example is before open
ImageIO.write(webcam.getImage(), "PNG", new File("test"+".png"));
webcam.close();

BTW - do I need to defiantly have webcam.open() and webcam.close() ? - close is the more problematic one... as it is standalone app and I may need to do some shutdownhook to be able to call close

For now there is no need to open(), it will be opened automatically on getImage(), but please be aware I want to drop this feature in next release since it really complicates synchronization code...You don't need to close() at all, there is a build-in shutdown hook which close the webcam automatically when JVM exits gracefully. Please note that in such a case your webcam power diode will be be enabled until you close your app.

In terms of trace log. Could you please disable logging mechanism you are using and replace it by SLF4J + Logback? The best would be to extract small example from your program and perform tests on it, so you don't have to change your code at all. WebcamLogConfigurator is a debug tool I wrote for my own purpose and it is able to work with Logback only.

I was under impression that we do not need the logging anymore as we know now how the problem is showing itself ? I guess if you run the following code it will crash for you too ? or it works for you ?
Webcam webcam = Webcam.getDefault();
webcam.open();
webcam.setViewSize(new Dimension(640, 480)); // <---- this where it is in my code in your example is before open
ImageIO.write(webcam.getImage(), "PNG", new File("test"+".png"));
webcam.close();

Hi,
I've just read again your comment where you conclude where the error is located, and I confirm. I just took a brief look on it in my email box when saw it first and simply missed this point :P Sorry for that.
I cannot reproduce it, but I'm on Ubuntu, so will have to try it later on my Windows XP or Vista machine. However, it's most likely the root cause since webcam is being configured on the very beginning when you call open(). When you set different size later, it will update resolution in Java, but native grabber is still on old resolution. There should be no issue in case if it was higher, but in case when old resolution was smaller then new one, this code could possibly cause the error observed in hs file:
Pointer<Byte> image = grabber.getImage();
Dimension size = dimension.get();
bytes.set(image == null ? null : image.getBytes(size.width * size.height * 3));As you can see, it tries to read 3 * width * height bytes starting from the pointer, but when allocated memory size was smaller, it can lead to access violation.
I will change setViewSize() method and add statement to check if webcam has been already open. The best approach imho is to throw exception in such a case, so all developers will be aware of issue in the code. The other solution is to ignore resolution change after webcam is open, and simply do nothing, but this could lead to misunderstandings, since one could suppose that his/her code actually works fine because there are no errors.

I suggest put some flag if the setViewSize is called once for the webcam and then rise exception for any subsequent call to setViewSize

Mmm, but in such a case resolution once set, will not be able to be modified. Actually I have code ready and tested where I throw exception after someone tries to change resolution after webcam is open. Will be submitted in few minutes.
