TS-7372 Learn how to integrate video with Java™ and JavaFX™ technology
2008 JavaOneSM Conference | java.sun.com/javaone | 4 Agenda
Introducing Parleys.com What do we need? Java Media Framework (JMF) technology Introducing FOBS Streaming Integrating with JavaFX technology
2008 JavaOneSM Conference | java.sun.com/javaone | 5 Introducing Parleys.com

Uses web 2.0 features with a lightweight Java Platform, Enterprise Edition (Java EE) back-end
Flex/AIR front-end enables offline viewing and delivers a rich user experience
2008 JavaOneSM Conference | java.sun.com/javaone | 6 ParleysFX Parleys.com
2008 JavaOneSM Conference | java.sun.com/javaone | 7 What do we need?
Technology Sufficient? Platform independent Java™ Rich user experience JavaFX™ / JOGL Comm. with JavaEE backend HTML java.util.regex.* JSON JSONLib / JavaFX™ XML javax.xml.xpath.* Flash FLV Audio / Video JMF
2008 JavaOneSM Conference | java.com.sun/javaone | 8 JMF Technology is dead…right!?dead…right!
Development paralyzed since 2003
Doesn’t support any of today’s popular codecs: FlashVideo, MPEG-4 ASP (aka DiVX), MPEG-4 AVC (aka H.264)
“In the current world of YouTube, Flash, and iTunes, video has gone from a niche capability to a checkbox item that all platforms must support.” – Chet Haase
Sun’s is working on Java Media Components (JMC)
2008 JavaOneSM Conference | java.sun.com/javaone | 9 Introducing FOBS
Ffmpeg OBjectS is a set of object oriented APIs for media
C++ Wrapper around ffmpeg LGPL media library • Native libraries for Windows, Linux, Mac (x86 & PPC)
JMF API Plugin: Fobs4JMF
Add support for flv, ogg, theora, xvid, h264, … to any JMF API application
2008 JavaOneSM Conference | java.sun.com/javaone | 10 FOBS tips & tricks
Add native library in JNLP descriptor
2008 JavaOneSM Conference | java.sun.com/javaone | 11 Fobs4JMF + Swing™ Code Sample
FobsUtil.initFobs(); // Register plugin + load lib
Manager.setHint(Manager.LIGHTWEIGHT_RENDERER, true);
Player mediaPlayer = Manager.createRealizedPlayer(url);
panel.add(mediaPlayer.getVisualComponent());
mediaPlayer.start();
2008 JavaOneSM Conference | java.sun.com/javaone | 12 Streaming Flash™ Video (FLV)
Only basic support for RTP and HTTP in JMF API and ffmpeg
Option 1: progressive download
Buffered Downloading
• Disadvantage: No seek!
Option 2: intelligent progressive download • Read FLV metadata, download specific position (HTTP Range header)
Meta Buffered Downloading
2008 JavaOneSM Conference | java.sun.com/javaone | 13 Integrating with JavaFX Platform
JMF API can render on a Swing JComponent
JavaFX platform supports wrapping Swing components • SwingWidget on the JavaFX platform Wiki • ComponentWidget (JavaFX compiler)
JavaFX platform wrapper is unaware of Swing component refreshes • @see my blog: http://javatrack.blogspot.com
// Scheduled repaint on video canvas @ 25 FPS attribute timerTick:Integer on replace { videoWidget.getComponent().repaint(); }
2008 JavaOneSM Conference | java.sun.com/javaone | 14 Summary
Java platform / JavaFX platform does rich media
JMF technology is dead but Fobs4JMF fills the gap • look out for Java Media Components API
Streaming can be simulated for the user
Mixing Swing and JavaFX platform requires redraw triggers
Parleys.com is a great eLearning site
