Pkg.test demo "video_recording.jl" has a load error
When loading video_recording.jl in the Pkg.test demo, the following error gets thrown. Might this be from a difference in macOS to Windows or Linux path naming conventions/functions that return path names?
LoadError: could not spawn `ffmpeg -f rawvideo -pixel_format rgb24 -s:v 1362x1362 -i pipe:0 -vf vflip -y /Users/crashburnrepeat/fxdkBHdE.mkv`: no such file or directory (ENOENT)

Do you have ffmpeg installed and accessible via the path? I need to figure out how to make this a dependency of glvisualize - or maybe just rely on VideoIO.
Fair point. I went and installed ffmpeg and the demo at least runs now, although based on the REPL messages I don't think it's working properly. If I'm understanding the code correctly, this is supposed to produce a video of the cat model changing colors? In any event, this is the REPL message I get:

I also looked on my computer for the /Users/crashburnrepeat/fxdkBHdE.mkv file just in case, but no dice.
this looks good. i think the file will get deleted after you run this!
All I see though is the cat object in red, which I'm guessing is the final color in the sequence. Is there supposed to be another accompanying visualization?
