I've used bigbluebutton in a recent project in order to build a web conferencing platform. I was unhappy with the quality of the service and noticed a delay between the voice and the video.

Technically bigbluebutton used Flex integrated with a red5 server that sends the voice to Asterisk for voice mixing (Konference) and treats the video locally by implementing a codec in java.

Bigbluebutton is very well done and the sources are really well written. As I understood that Flex it self limited to choice of media server implementation such as the impossibility to implement UDP sokets etc.

So my question is that,another way than Flex to implement video chat application in browser. Is JavaFX a good solution ?

Answer 1

Is JavaFX a good solution ?

No. Perhaps in the future (e.g. JavaFX 3.0 next year), but not now.

JavaFX currently has no in-built camera or microphone support.

To build such support yourself you would need to rely on a non-JavaFX library (such as lti-civil) and then interface it into a JavaFX application. As JavaFX is just Java and JavaFX apps controls can be embedded in Swing applets, this is all possible, so you could consider it. To get to the point of an end-to-end solution with all of the features of BigBlueButton would be a great deal of work.

Answer 2

I am one of the developers of BigBlueButton. In the latest version of BigBlueButton (0.8) we replaced Asterisk with FreeSWITCH and moved to the speex protocol.

I'm not saying that BigBlueButton is good enough for your application, but I would suggest you try the latest version as you'll notice the delay in audio much less in 0.8 than in 0.71a.

You must see beyond JavaFX API and into Java API itself.

I think Pure Java Applets could do Microphone and Webcam things in 90's when Flash wasn't even in existence.

You just need to use Core Java Classes like JMF, JNI, JNDI
