MøB-0.53

[220hex]

MøB version 0.53 is out!

The initial release of MøB is now ready for download.
MøB is an open-source tool for live video processing and interactive
installations being developed at BEK.

Changes in this release:

1) autoconfiscation.

- This is how people who love automake/autoconf
call the process with which a software package is put under the
protective wing of these mammoth packages. As a result of this
process, installing the software should be much easier. If you
download from the CVS, be sure to run the 'bootstrap' script (this
means that you must have installed autoconf (at least version 2.57),
automake (at least version 1.7) and libtool (version 1.4.3). After
running 'bootstrap,' run 'configure' as usual with those fancy
packages. Needed libraries are:

- GTK and Glib, version 2.2.1 or greater.
- OpenGL, as included in recent XFree distributions.
- Libmpeg3 and libquicktime: the debian packages that I used are
respectively version 1.5-4 and 1.3-5 (remember to install the -dev
packages too).
- Libmagick (part of the ImageMagick package)

Furthermore, you must have at least version 3.0 of the GNU C
compiler!

IMPORTANT: this means the set of files is completely rearranged! If
you have downloaded MøB already, make sure to remove the old
directory before doing the new cvs checkout!

2) New modules.

- Freeze. To be used for the Freeze installation (the mother or all
møbs). Tho have a potentially large number of different inputs. For
each input, a number of captured frames is stored (currently a maximum
of 24). You use two independent algorithms to control which images to
spew out: the first algo controls which of the input is used, the
second one which of the history of images to play back. In short, we
travel in time-space here.

- MPEG module. Allows you to play MPEG or Quicktime movies, if they
are understood by the two libraries described above, and their
codecs. The module allows you to play the video frames of the movies
according to the output of an algorithm module. The whole of the movie
or part of it can be selected for the algo value to be applied.

- Chromakey module. A last-half-day hack, that miraculously seems
to work. Two input and one output. The pixels of the first input are
output except when they have a R-G-B value included in presettable
brackets: in this case, the pixels of the second input are passed.

3) Module upgrades

- Algorithms. Major revamp: it is now possible to apply a sequence of
algorithms (max. 8), and for each you can change the application
level, and the level offset (as well as the phase offset, that was
already accessible). It is possible to flip the effect upside down. It
is possible to have a graphical representation of the ongoing value of
the algorithm, by adding the standard video parameters (out, xres,
yres and bpp) to the module's XML definition. A couple of new
algorithms (cycloid, hyperbolic tangent) have been added.

- Effects. here too, multiple effects can be applied in
sequence. Originally, the three available effects had to be applied in
a fixed sequence, now you can apply each effect more times, and in any
order.

4) General mechanism.

- It is now possible to unload scripts. A new program, called
'mobloader,' substitutes the testing loader called 't1.' Use this
program also to unload scripts.

- Peek_mobber has been heavily revamped, too. You have a scrollable
module data area, a menu with possible operations, and from the menu
you can start/stop the main daemon, and load/unload scripts, as well
as refresh the script situation, save the situation to disk, and quit
the program. Ah, there is also a marvellous logo!
