What's New in the JMF 2.0 Reference Implementations
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, 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
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).
FramePositioningControl 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 greater New Features in JMF 2.0 Beta
Playback support for new file types
(see the complete supported formats list):
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 were not implemented 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:
FormatControl for setting and changing formats on capture DataSources
FramePositioningControl for stepping in seekable media types (e.g. QuickTime, AVI)
BufferControl for RTP DataSource and JavaSound renderer for contrg latency
MonitorControl for processors
Support for more capture devices. See Capturers for a list of supported capture devices
Updated the JMStudio GUI to the Java-look-n-feel and for better support of transcoding and RTP transmission
Added a new application "Export" for advance use of transcoding, previewing, etc.
Beta API changes. See the change list
