ogg video file format :
Ogg Vorbis (sometimes just called Vorbis) is an open source patent-free audio compression format, developed as a replacement for proprietary digital audio encoding formats, such as MP3, VQF, and AAC. Vorbis files (which have an .ogg extension) compress to a smaller size than MP3 files, which reduces bandwidth and storage requirements. According to many reports, Vorbis provides better sound quality than MP3.
