Palm and J2ME.. Very nice

Hand in Hand with PalmSource
Excerpt from the article:
Also at the conference, PalmSource announced it has licensed IBM’s WebSphere MicroEnvironment Java 2 Micro Edition and the WebSphere Studio Device Developer toolset. PalmSource will integrate WME into its platform, making it easier for the huge community of Java developers to create apps for the Palm OS. It will also let Palm developers execute Java MIDlet applications on Palm devices.

Java wrapper for ffmpeg

SourceForge.net: Project Info – JMF wrapper for ffmpeg
Very nice, JMF needs a refresher (an understatement) and it is nice to open source implementations picking up on it (especially since Apple has no idea what they are doing to QuickTime for Java).
From the site:
This is a Java wrapper for ffmpeg compression library. It exports ffmpeg codecs functions as a JMF (Java Media Framework) codec. You can use this codec from JMStudio and then you’ll have a video player able to play mpeg1, h263, mpeg4 (divX), etc. streams.
