Hi,
Thanks for the sample code to connect to JMF.
Is it ok if I create a short wiki page on this topic and add your code ?

Hi, I've compiled your sample code with some modification related to
the v4l4j version, but it only worked sometimes, most of the times it
failed and the error message is:

===================================================================

Does anybody have tried this and know what the problem is?

Hi,
I have not tried Alexandra's code yet so I cannot help you out with
this. I might be able to see if it comes from v4l4j if you share the
code you are running.

Hi,
It's just the sample code provided by alexanda, nothing modified
except some version related symbols.
And I'm confused that I can run it successfullly first 2 or 3 times,
after that, I just got no lucky, nothing changed...
