What's new in the JMF 2.0 Reference Implementations

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, ie 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, egfile: //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

New Features in JMF 2.1.1 Beta 1

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.

New Features in JMF 2.1 FCS

Initial Linux Port Delivered to Blackdown.org Optimized Video Rendering for SunrayTM on Solaristm. Video Scaling. Complete RTSP Client. Numerous bug fixes.

New Features in JMF 2.0 FCS

MPEG layer III (mp3) audio encoder. Cinepak pro video encoder on Solaris. Audio and video monitoring via MonitorControl from the processor. Video monitoring for VFW capture. Non-realtime software video scaler. Registration of new mime types via MimeManager (in the com . SUN PACKAGE). FramePositioning Constrap Fully Supported. Early Access Preview:

RTP Mpeg Audio and Video Support for Transmission and Reception. RTSP Reception. Improved GUI Design for JMStudio.

New Features in JMF 2.0 Beta 2

JavaSound capture functionality enabled when running as an applet in Netscape The all-java JPEGRenderer is enabled Playback of MP2 audio files fixed for all-java JMF MPEG movies on Solaris can play if the audio device is not available DirectShow MPEG player can play in MS Internet Explorer Plug-in's can be registered when running under Java 2 SDK, version 1.2 An application can use setSecurityManager () to set its own security manager in Java 2 SDK, version 1.2 or greaterNew Features in JMF 2.0 Beta

IBM HotMedia Macromedia Flash 2 MPEG-I MIDI File Writing for the QuickTime Format. New Codecs (See the Complete Supported Formats List):

MPEG-1 system stream decoder All-java MP3 decoder <-! REMOVE UNTIL JMF 2.0 FCS - NEED LEGAL PERMISSION TO USE ITU standard G.728, G.729 decoders and encoders for use with RTP -> RTP Processor for processing and Saving RTP Transmitted Data To Files A New Mechanism To Clone and Merge Datasources Completed API Features That Wee Not Implement In The EA Release:

Converters to Convert from java.awt.image to javax.media.buffer; And Vice Versa Creating Processors from Processormodel's (Manager.createRealizedProcessor) NEW Controls:
