Adobe has released an update to Open Source Media Framework (OSMF), an open framework for building custom media players.
OSMF was developed to help streamline media player development by allowing developers to assemble pluggable components to create high-quality, full-featured playback experiences. Version 1.5 supports all of the Multicast features recently launched Flash Media Server 4, including: native IP Multicast; Application level Multicast (peer to peer) and Multicast Fusion
OSMF 1.5 also supports stream reconnect so that if a network connection is lost, it will seamlessly switch to another available network. OSMF 1.5 can be downloaded for free at http://www.osmf.org .
