For now, the situation is : DTS acknowledged that the ECP stopped any
form of public distribution of libdca (don't call it libdts!!!). Their
lawyer says they're ready to negociate license for internal
developments on the ECP campus.
Of course, it's not as if we (the students of ECP) cared about a such a
license - we were not even involved in the developing libdca in the
first place, only for hosting it on the VideoLAN project server. FYI,
it is Gildas Bazin who implemented libdca and he's not a student here
(countrary to what DTS believes).
It is our (the official VideoLAN project at the ECP) understanding that
it is very unlikely that we'll get any kind of license that would allow
us to provide libdca under any kind of GPL-compatible license. And
that, should it be the case, it will take *LONG*. In other words, it
As for the administration of the ECP, all they want is not be bothered
by IP/legal issues. They probably couldn't care less if libdca is
distributed from somewhere else so long as they (their IP addresses
space) aren't liable in any way.

We can keep the mailing lists. In fact, it's still running, and the
archive is publicly available there :
As for the SVN repository, Antoine Cellerier and I agreed, we'd leave up
to Gildas to decide if he wants to move it. If he agrees, I can send a
copy of the Subversion repository (*except* password stuff). I can also
put a copy of the libdca-devel's mailbox archive for downaload if
someone really wants it.

DTS noticed it only a few days after libdca initial public release which
came at about the same time as the first release VLC media player
including libdca. That was in early 2004. Things became hot as DTS
hired a lawyer in France to sue our school. We stopped distribution of
libdca at about time DTS patent was granted in E.U. (october 2004).
Things have settled since then (December 2004) with their lawyer taking
notice of our goodwill.
That is to say they are very serious about their IP rights. It is their
primary business. Royalties are their source of income.

It's a VLC-specific issue - it's not very good at building of external
modules from source. An alternative might be to make libdca some kind
of dynamic library that can easily be dlopen'd or whatever.
