To convert the frames into a movie playabale in the visualization labs, the following command should be used:

ffmpeg -r 60 -f image2 -s 1920x1080 -i %04d.png -vcodec libx264 -crf 25  -pix_fmt yuv420p test.mp4

Will create a movie named movie.avi at 15fps from the files contained in the folder screens named frame0000.png, frame0001.png, etc

# This is a script designed to take two images and interlace them. For a usefullness

Since it is not possible to play a single 41MP movie on the AESOP display due to bandwidth issues, we split it up into one for each display. At this point we need a program that synchronises the play/pause actions across all the nodes and screens. For this purpose we use VB.3

First we need to define the CGLX default configuration so VB.2 knows the nodes, the screens on the nodes, the screens' details, ip addresses and port numbers required for playback. In this case we are using the AESOP display (zone 2 hence the usage of z2-csdefault.xml).

export CGLX_DEFAULT_CONF=/opt/kaust/config/cglx/z2-csdefault.xml

Now we launch VB.3 telling it that it will be displaying on 4 rows, and the folder containing the movies named in column, row order.
For example, we can name the files with the following format:

screen_<column>_<row>.avi

neuralvis

var docElm = document.documentElement;
if (docElm.requestFullscreen) {
    docElm.requestFullscreen();
}
else if (docElm.mozRequestFullScreen) {
    docElm.mozRequestFullScreen();
}
else if (docElm.webkitRequestFullScreen) {
    docElm.webkitRequestFullScreen();
}
