Vorbis dev - Sep 2000 - Adding oggenc support for files other than WAV?

Is anyone working on making oggenc use some nice library that reads lots of
different audio file formats so that people can encode from files other than
WAV?  For example, the 'AudioFile' library (just found it via a search
on freshmeat) reads wav, aiff, aiff-c, .au, and .snd.  Maybe there are other
better libraries (OpenAL, maybe), but this library does what I want (read AIFF).

I am working on an audio library with Vorbis support, which will do
what you want.  If you're looking for something more than reassurance
(e.g. source code) - it's not ready yet.

Oggenc was designed so that this would be VERY straightforward to
implement. There's a static array somewhere near the start which oggenc
walks through. This contains function pointers and misc. other info. Oggenc
will try each of these in turn until one returns successfully. This
function is responsible for setting up some other variables and function
pointers which are used for oggenc to read raw audio data. 

It's completely untested, since only wav reading currently exists, but
it's
not conceptually all that difficult - so I think it should work.

ox -t auto your.file -t wav - | oggenc .....

It is not a library, but if you write a wrapper shell script for the
above
command line, it will look ( and fell ) like one.
