.deb file requires another package
libjpeg-turbo8 that is not available on newer versions of Debian (e.g.: not on the Debian Stretch that we are running). So you have to compile from source.
Connect the board to the internet and run:
apt-get install libturbojpeg0-dev libsdl2-2.0-0 libsdl2-dev libdc1394-22-dev
then copy the reactivision source code to the board, go to the
linux folder and type
make. Once it's built,
./reacTIVision will launch the program. This is as far as I got, because I have no cameras connected (I have no USB cameras around), so I get:
reacTIVision 1.5.1 (Sep 14 2019)
no DC1394 cameras found
no V4Linux2 devices found
error: XDG_RUNTIME_DIR not set in the environment.
SDL could not be initialized: No available video device
If you have a USB camera, you can try the steps above and see if this gives you something useful.
