Setting up an automated lecture capture system at my university, based around the open-source https://opencast.org https://opencast.org software. We did everything from buying hardware components to build machines that were specifically tuned to encode videos on the fly with the least space/noise possible to be put into lecture halls, writing the software to run on that, to running the video management system with opencast, integrating it with e-learning suites, setting up livestreams, etc. I left the university and that job exactly one year before COVID-19 hit, and as far as I heard having that system in place saved a lot of butts - lectures seamlessly shifted to fully virtual with teachers recording videos either at home or in empty lecture halls, and pushing it through these video management systems. We pushed a lot in 2015 to get approval for this whole endeavour, even though the university big-wigs pushed heavily against this, fearing that students would not come to lectures anymore. Turns out: that fear was bullshit, and in the end it helped out a lot of people.
