1. The Java Media Framework http://www.lehigh.edu/~wcd2/csc350/jmf by wayne deprince wcd2@lehigh.edu

2. The Java Platform The Java Virtual Machine (JVM) –system services –implemented on host platform –extending the JVM through the Java Native Interface (JNI)

3. The JVM Extensions (javax) Non standard services Usually implemented using another technology of the host platform Multimedia extension examples –JavaSound –Java3D –Java Media Framework (JMF)

4. JMF Javax package used to play streaming and non-streaming media Application framework Plug-able media players Supports many media formatsmedia formats User defined players

5. JMF Implementation Win32 –Direct X Media –DirectShow –QuickTime JNI

6. Pros / Cons Pros –It’s Java –Easy to program –Takes advantage of all host platform technologies Cons – It’s Java –Java Extension Problem non standard JIT/WAT Compilers –Native technologies usually faster

7. The Road Ahead for JMF Depends on the success of Java –the JDK problem –the javax problem Time … http://www.lehigh.edu/~wcd2/csc350/jmf
