Need help about sample applications (2012-03-07 18:56 by 匿名 #62642)
Dear all:
I'm trying to use the sample application "Real time QR Code reader by Java Media Framework(JMF) and PC camera"
I use eclipse as IDE tool, my PC is windows XP 32 bit
and I have already install the JMF and my webCam can work in JMF.
But when I trying this sample, it show " Your camera is not connect"
and the Exception is below
Exception in thread "main" java.lang.NullPointerException
at javax.media.Manager.createProcessor(Manager.java:663)
at jmf.camDataSource.startProcessing(camDataSource.java:68)
at jmf.jmfexample.<init>(jmfexample.java:18)
at jmf.jmfexample.main(jmfexample.java:30)
