How can I encode to OGG vorbis under linux / *nix?
The vorbis tools ( for encoding and decoding ogg ) are part of most modern linux distributions, check your distributions’ repositories for binary packages. As always debian users can get plenty of vorbis apps from www.rarewares.org/debian.html. You can also grab and build the source from vorbis.com. For basic encoding/decoding needs, you’ll want to install libogg, libvorbis, and vorbis-tools (in that order). Vorbis encoding is also supported in VLC and several other encoding tools.
