ooVIC: object-oriented vic wrapper

ooVIC is based on version 2.7a38 of the vic video conferencing tool from LBL. It was written by Loring Holden of Brown University and Arno Schaefer of the Fraunhofer Center for Research in Computer Graphics, and is currently in beta testing, with planned full release by the beginning of July '96.

ooVIC Features

Multi-threaded decoding (one thread displaying one or more movies, and one thread to decode each movie)
Written in C++ using the same interface as ooMPEG, so ooVIC can be used by testwrapobj and AnimatedTexture2 easily

To Do

Ability to quit and restart the vic program that is sending data and have ooVIC deal with it nicely (now works except with At2 at times)
Ability to set ttl
Include hardware decode assistors
Fix permissions on files so that they are writable

Tested configurations

ooVIC has been tested on the following configurations using version vic 2.7a38 from lbl. If you get ooVIC working on other configurations, please email lsh@cs.brown.edu

Sun UltraSparc, SunOS 5.5 (Solaris 2.5), 1 and 2 processors
Silicon Graphics Onyx Reality Engine 2, IRIX 5.3, 2 processors

Necessary ingredients

vic 2.7a38 (you MUST have this version), located at ftp://ftp.ee.lbl.gov/conferencing/vic/2.7/vicsrc-2.7a38.tar.gz
ooVIC source (compressed tar archive, 74k)
Beta version of ooMPEG. See the page for more information on installation, but you must use the code at ftp://ftp.cs.brown.edu/pub/AnimatedTexture2/ooMPEG.beta.tar.Z. Make sure you edit mpeg_play/Makefile so that NOVIC is not defined, and the lines pointing to the vic library are uncommented.
If you want to use ooVIC with AnimatedTexture2/ you use the beta version of that package

Installation instructions

Unpack the vic tar file, which will extract the package into a child directory called vic-2.7a38
```
gunzip -c vicsrc-2.7a38.tar.gz |tar xvf -
```
Make a link from vic to the vic-2.7a38 directory
```
ln -s vic-2.7a38 vic
```
Change the permissions on the files in the vic directory so you can write the ooVIC files over them
```
chmod +w vic/*
```
Unpack ooVIC in the same directory as you unpacked vic-2.7a38 (the parent directory of vic):
```
zcat ooVIC.tar.Z | tar xvf -
```
Edit the Makefile (in vic/Makefile) for your platform
Make the package
```
make depend
make
```

Information

The files that were massively changed by me have a Brown copyright message at the beginning, the ones that were slightly changed have a small message from me at the beginning.

Please see the Brown copyright message for the legalese in reference to use, redistribution, and modification. Also, please notify me of any changes you make to the package so I can include it in the main distribution.

If you do use this package at all please notify me, I'd love to hear about it!
