What is JMF 2.1?
This is a dot release which added SunRay and Linux support, increased support with open standard RTP-based video servers such as Apple’s Quicktime Streaming Server and Sun’s MCSS, and many bug fixes and optimizations. Note this is not a new API release; the same JMF 2.0 API was used for both JMF 2.0 and 2.1 implementations from Sun Microsystems, Inc.
