Here are the open-source projects I am involved into:

VLMa: VLMa is an application to manage broadcasts of TV channels, received through digital terrestrial or satellite ways. Its interface is provided as a web-site written in Java. It is also capable of streaming audio and video files. VLMa consists of a deamon (called VLMad) and a web interface (called VLMaw).

VLC Media Player: VLC media player is a highly portable multimedia player for various audio and video formats (MPEG-1, MPEG-2, MPEG-4, DivX, mp3, ogg, ...) as well as DVDs, VCDs, and various streaming protocols. It can also be used as a server to stream in unicast or multicast in IPv4 or IPv6 on a high-bandwidth network. It doesn't need any external codec or program to work.
