Editors' Note: The VLC Media Player source code is also available.
VLC (initially VideoLAN Client) is a highly portable multimedia player for various audio and video formats, including MPEG-1, MPEG-2, MPEG-4, DivX, MP3, and OGG, as well as for DVDs, VCDs, and various streaming protocols. It also can be used as a server for unicast or multicast streams in IPv4 or IPv6 on a high-bandwidth network.
What's new in this version:
2.1.5 fixes a few decoding bugs, on MP3, MKV, and hardware decoding on Windows.
It also fixes QTsound capture and audio channel orders for OS X.
2.1.5 also ships with updated GnuTLS and libpng libraries, because of security issues.
