Error Opening video stream: /dev/video0 #8

Open roberttamas98 opened 2 years ago

roberttamas98 commented 2 years ago

I'm getting "Error Opening video stream: /dev/video0" quite often when I want to call d.connect() and sometimes while already connected I'm getting "Unable to grab frame from D00123 - /dev/video0!", even though my Digit is recognized and video0 is actually active. First I thought it might be a loose contact, but I'm having the same issue when my Digit is just lying around and if I'm trying to connect again, a lot of times my Digit isn't recognized at all and then all of a sudden sometimes it's recognized again. The most reliable solution to get it running again is plugging it out and back in, but that's not a practical solution when trying to work with it.

I am also having this issue! It seems to connect reliably to my Ubuntu 20.04 computer but is failing to connect to my Ubuntu 18.04 computer (default python: 2.7, but trying to use digit in a conda environment where python 3.8 is installed).
