ogg dev - Dec 2009 - Fwd: Vorbis-java wav-ogg encoder produces distorted OGG file

Hi,
I was really interested in the java version of the same since I wanted to
use it in my java application in a platform independent way.
Anybody who have managed to use the java port to encode wav to ogg, this is
only audio, can assist me to solve my problem. I have been looking at the
code and the svn but no updates seem to be available. Some guidance on what
could be the problem on the source will be helpful so that I can try to
locate the necessary files and try to modify them to see if it functions
properly.
thanks

I have the impression only a small piece of this conversation is being
forwarded to ogg-dev.  We can't answer questions when we have no idea
what's going on :-)

that ffmpeg command line is telling ffmpeg *not* to use its internal
video, but to use the external xiph encoder (libtheora) instead.  In
fact, ffmpeg's internal ogg and theora support is somewhat broken
across the board.  Our ffmpeg2theora application uses ffmpeg for
everything *except* the ogg production.

Again, can't help only seeing a handful of the messages.

So to which group should I foward my question? I thought this was the most
appropriate of them all. Please guide me
