[vorbis-dev] Some Questions

[Stephen So]

Wait. No, it was my mistake. You were talking about video codecs while I
was under the impression you were talking about the Vorbis audio codec
(since this is the Vorbis mailing list) :)

By the way, I'm not a developer. I'm just someone who follows this
mailing list. :)

Best regards,

Steve.
