How to transmit live video from within a Java application?

Question

I'm trying to find ways to stream a live video generated in a Java application. The application needs to take screenshots of itself and encode these into a video stream and publish the stream.

So far I have been using Xuggler (a Java library on top of FFMPEG) to encode the screenshots into a video file. This works great. Xuggler claims to be able to transmit live video via RTMP but I have not found any documentation on how to do this programmatically.

1. Does anyone know how to stream RTMP video programmatically from Xuggler?
2. Does anyone have a suggestion on other libraries I could use to achieve the same results? I'd prefer to stream the video in MPEG2 over RTP.

I did find someone else asking a very similar question on the Xuggler forums here with no response.

I have looked into JMF and it is not an option for other reasons.
