It isn’t particularly applicable to the world of live visuals, but we recently did a bit of work helping fix some bugs / add some features to this command line tool that is used as part of an interesting .mxf to ProRes workflow, https://github.com/Vidvox/prores-encoder-mac
I recently created a “gif2mp4” service with it, which allowed me to select a bunch of gif animations and Right click to run the same ffmpeg script over & over. Playback of multiple GIFs take up a lot of CPU so batch conversion to MP4 (& then HAP) helped performance quite a bit.
dshb for a small system stats monitor. Really handy to keep an eye on media servers back stage. Takes a bit of SMCKit/HWMonitor tweaking to get your dGPUs reporting tho.
