JMF Documentation

New Features in JMF 2.1.1 FCS

• Improved RTP API
• Added support for H.263/1998 (RFC 2429) - now can interoperate with Darwin based RTSP servers.
• Direct Audio Renderer and Capturer
• Performance enhancements with new Java compilers
• JMF Customizer added to all JMF versions
• HTTPS, JAWT, UNC pathnames support
• Numerous bug fixes

New Features in JMF 2.1.1 Beta 3

• The JMF Customizer has been added to the JMF performance packs.
• The quicktime file writer now creates streamable Quicktime files, i.e. the header is at the beginning of the file. When used, a temporary file is created then deleted after the streamable file is created.
• UNC paths are now supported, e.g.
  file://unixmachine/home/videouser/video.mov
• RTP Connector: a new interface that allows developers to connect JMF/RTP to their own and possibly proprietary transport services.
• RTSP Processor has been added
• A new control that provides a handle on RTPManager objects to retrieve RTP statistics from the RTSP Player
• The RTSP Player now handles multiple audio & video streams
• Added JAWT support for jdk1.3+
• Key Bug Fixes:
  • Frame by Frame stepping of avi files now works properly
  • Quicktime files can now be created with more than 25000 frames.
  • Fixed "ClassCastException when playing from an input stream"
  • Fixed "Renderer for Sun Ray crashes when runnning with Corona 1.2"
  • Fixed "Transmitting H.263 with size < 176x144 crashes the VM"
  • Fixed "Transmitting video only H.263 from files with A/V may not loop back"
  • Fixed "ByeEvent's are not sent reliably from the RTPManager"

New Features in JMF 2.1.1 Beta 2

• Minor RTP API updates:
  • RTPManager is changed to be an abstract class
  • The javax.media.rtp.Manager class is removed
  • A new method newInstance() is added to the RTPManager class to instantiate an RTPManager
  • Renamed Methods:
    • openConnection() -> addTarget()
    • removeConnection() -> removeTarget()
    • removeConnections() -> removeTargets()
• Performance optimizations on JMF when running on JVM's with native non-pinned arrays (JDK 1.3, Internet Explorer etc.)
• DirectAudioRenderer is used as the default audio renderer on Solaris 2.8 and above
• Numerous bug fixes

• RTP API updates.
• RTP client lip-sync improvements and some other optimizations.
• Added DirectAudioRenderer and DirectAudioCapturer for performance packs.
• Added arbitrary audio rate conversion codec.
• HTTPS (secure sockets) protocol support.
• Extended customizer to customize performance packs.
• Numerous bug fixes.
