Back on topic.
Been messing with the homebrew setup for about 5 hours now and finally got it working. Sort of. I’d say the lag between action and video is in the 3-4 second range. This is WITH the paid version of DroidCamX, using USB.
Using wireless was just about as bad. Neither is usuable.
Things they don’t tell you up front. You must enable USB Debugging, and must download phone specific USB drivers to the PC being used.
I’m tempted to Amazon a proper webcam. Supply is coronavirus borked though.
Might just ditch the PC and record to phone. A bit awkwardish, but given the workarounds necessary to use a PC, maybe not that bad.
Anyways, I’m done fooling with it for tonight.
P.S. The perspective from the arm is really nice, will make for good videos, just laggy.
