Notes / tips / tricks

In most notebooks I launch a single meshcat server (as a subprocess) in the first cell. Especially when I'm working in VS Code, I end up with an accumulation of meshcat server instances hanging around. Running an occasional

pkill -f meshcat

will clean them up.

For lecturing

My current (proposed) solution:

• OBS on Ubuntu
  • Connect ipad via this Airplay recevier on Ubuntu: https://github.com/antimof/UxPlay
  • Share with Zoom via "Windowed Projector (Source)". Drag the window to make it big (full resolution) and to fit the content nicely. Then I can minimize it.
  • Google Hangouts meet speaker
  • Brio for video (through OBS? or directly?)

I've tried a number of solutions.

• OBS
  • Never worked well for me on mac; at least not on the macbook air. It might have been starved of resources.
  • I got things working beautifully on ubuntu, and could push to YouTube at a nice screen quality.
  • The sharing to Zoom, both with the virtual camera and the desktop sharing, resulted in a dramatic loss of resolution. To the point where it was unusable. Update: Seems to be resolved with version 26.0.2
• Mmhmm
  • Again, resolution of the screen share with zoom was a bottleneck
• Zoom (only) on mac
  • Worked for me for a while. Painful switch between ipad and slides. Fan is always on and loud; the machine sounds like it's dying. Active dis-incentive to have meshcat open.
  • Airplay sharing of ipad stopped working when I upgraded zoom to 5.3.1 . I spent some time trying to downgrade but gave up.
  • Have been sharing ipad via usb, with a usb3 splitter sharing a port between Brio and ipad.
• Zoom (only) on Ubuntu.
  • Brio video
  • Google Hangouts meet speaker
  • Connect ipad via this Airplay recevier on Ubuntu: https://github.com/antimof/UxPlay
  • Couldn't find the gstreamer window as an option for window sharing.
