flac dev - Sep 2004 - Re: UCI Project Announcement

Greetings all.. I'm sending this message out here because I suspect that
some
folks involved in this project might be interested in the following.  If this
is not the case (or this is not an appropriate forum for this sort of thing) I
apologize in advance..


               Project Announcement and Call for Participation
               -----------------------------------------------

The Universal Codec Interface (UCI) Project is aiming to create a consistent,
well-designed, portable set of programming interfaces for multimedia
applications and codecs to interface to one another on unix-like (and
potentially other) operating systems.

The UCI system is intended to provide an interface which is both consistent
enough to allow easy ("plug and play") use of any codec by any
application,
while being flexible enough to allow sophisticated use of specialized codec
features by applications designed to take more thorough advantage of certain
codec implementations, or even to allow the user to control codec features of
which the application itself may not be directly aware.  It is not tied to any
particular system or set of other libraries (such as graphical environments),
and is intended to be lightweight and as efficient as possible so as not to get
in the way of application/codec builders.

We are interested in developing an interface which is well thought-out and
meets all the needs of multimedia applications and codecs, both now and in the
future.  To this end, we are inviting (and encouraging) participation by any
and all current multimedia developers or other interested parties, to provide
input and feedback on developing UCI specifications, suggest features,
contribute code, or simply keep up to date on the current state of the project.

UCI is an Open-Source, Open-Spec, Peer-Directed project.  Choice of licenses
and related issues are still somewhat under discussion.  Contributions and
feedback in this area are welcome, as well.

Everyone and anyone interested in contributing, knowledge, skills, critical
thinking, or anything else that might be useful to this project is welcome!  It
is our hope that through the participation of a range of contributors from
various backgrounds, we will build a system which is useful and effective for
everyone's needs, and will significantly simplify the development of both
platform-specific (linux, etc) and cross-platform multimedia software now and
in the future.

Those interested in the UCI project should visit the project web page at:

  http://uci.sourceforge.net/

A public UCI-Devel maillist is open to participation by everyone.  To
subscribe, point a web browser at:

  https://lists.sourceforge.net/lists/listinfo/uci-devel

..or simply send a subscription request to:

  uci-devel-request@lists.sourceforge.net

We also have an NNTP gateway, web archives, and an IRC channel on FreeNode for
discussing UCI development.  More details can be found on the main project
page.

Some basic specifications and documentation as to the current direction of UCI
development are available from the main project page.  Please note that these
"specifications" are preliminary and subject to change based on
feedback from
the larger multimedia community.  If you see something that looks wrong,
please feel free to contribute suggestions to the UCI-Devel maillist.

Thank you all for your kind consideration,

-alex

Hi folks,

please allow me to raise the subject again. Anybody had the time to check
http://uci.sf.net yet ?

The MCF team meanwhile has decided to use UCI as the only codec interface to
libmcf, at least for native MCF streams. There was also interest from the
XviD team to use UCI, at least in addition to the currently existing VfW
interface. A mplayer wrapper for UCI seems feasible and the OpenBeOS
mediakit people show big interest to make UCI the new codec API for their
opensource implementation of BeOS. Good input to UCI came from gstreamer
people, especially Erik Walthinsen, its founder, and Thomas van der
Stichelen.

Could you consider to add a UCI interface to your codec ? IMHO we have a
good chance to get some level of standardization in the opensource media
world, we shouldnt miss it.

I haven't investigated UCI yet and even then I really don't
have time to do an implementation.  But, as of flac 1.0.4,
there is a new library libOggFLAC which would probably be a
good model for what you want to do, and the whole API has
Doxygen-based docs (see http://flac.sf.net/api/index.html).
libOggFLAC basically wraps the libFLAC encoders and decoders
so that FLAC frames go into Ogg packets.  Someone who knows
UCI well could probably create a libUCIFLAC based on this code
pretty easily.
