Is there a Java RTP/RTCP library based on Java NIO or some Java NIO framework (Netty, MINA, ...)?
In Red5, we are adapting an RTP/RTSP library written using Mina. If you would like to check it out, go here: http://red5.googlecode.com/svn/java/plugins/trunk/rtspplugin/
The original library was written by Matteo Merli (matteo.merli@gmail.com) and yes, we have his permission to modify it.
