The location of the cpm library is always set using LD_LIBRARY_PATH in the local terminal - you do not need to take care of this in your program, as long as you have linked the library properly.

Lab Camera

The lab camera enables you to record your experiment. Turn the "Record" switch on, if you want to record your experiment.

After stopping the experiment, you will find the video file in the /tmp/ folder.

If you are planning to play the video on windows without installing codecs, convert the video e.g. with

ffmpeg -i $INPUT_NAME_WITH_FILE_EXTENSION$ -ss $START_IN_SECONDS$ -t $DURATION_IN_SECONDS$ -c:v libx264 -strict -2 -preset slow -pix_fmt yuv420p -vf scale=trunc(iw/2)*2:trunc(ih/2)*2 -f mp4 output.mp4

Deploy / Kill

When you have finished your setup, you can launch all the components / scripts by clicking on Deploy. Not all software starts immediately then. Some, e.g. those that rely on the Middleware, wait until you start the simulation in the Timer Tab. (Wait for the program to show up before you start the simulation)

...

Important note: Always use Kill after you have finished, or else some software might end up running on a system until it is restarted.

Relevant information for remote deployment

The HLCs use a startup script that takes the cpm library and the Middleware from an Apache server located on the Lab's main PC. The according files are updated every single time that these components are built. If you changed them during the lab run / if they are missing, please rebuild them and restart the NUCs/HLCs, so that they get the new software.

This decision was made to reduce upload traffic when files are uploaded to the HLCs during a lab run.
