Tim,
thanks for your kind answer. :-)
Unfortunately, the reason why we are using JMF at all, in fact is that
we are doing video capturing from USB Cam. Sad but true, this is
(certainly) only possible using the Windows Acceleration Pack. The cross
platform implementation cannot access video cameras, since there is no
support for such devices in Java SE. :-(
I wonder why Sun Microsystems didn't add a specification compliant
extension declaration into the JAR. I tried asking them, but their JMF
feedback link is broken and I think they won't change it (and even if
they do, it wouldn't be there in time -- I need it in two weeks running
at the customer's site).
Thanks
Markus
