README file from "bigVideoIn" directory

This directory contains 2 implementations of "bigVideoIn"


bigVideoInGL is implemented using a GL Pixel zoom.

The entire video source can be zoomed to an arbitrary INTEGER
zoom factor.  Note that this implementation does no filtering,
so the video will probably look blocky.


bigVideoInTex is implemented using a video texture map.

On the O2, you should see no drop in frame-rate performance
for live video input.  This video source will be cropped down
from 640 to 512 pixels in the horizontal direction due to
OpenGL limitations on texture map sizes, but the image quality
will be better.  This is because bi-linear interpolation is
used on texture map magnification and minification.  Also, an
arbitrary FLOATING POINT zoom factor can be used with this app.  



Installation:

These apps are based on the libdmu utility library.  Symlinks
of the dmu and pent libraries (pointing to 
../lib/libdmu/libdmu.so and ../lib/libpent/libpent.so) are
included in the distribution of this little app.  Place a copy
of these two shared objects wherever you want, then set the
LD_LIBRARY_PATH variable on your system to include that
directory.  You should then be able to run bigVideoInTex or
bigVideoInGL.


NOTE:  Press Escape, or close the window to exit the application.
