guvcview runs strange
« on: August 22, 2017, 07:17:52 pm »
guvcview has to be run twice before it will start properly on a fresh boot. afterwards it runs with one click. once you re-start the computer, you again need to run guvcview twice. What's up with this?

Sorry I am responding so late. I forgot about this post.

I ran the code you asked me to run, and yes, guvcview now launches with first run, perfectly.
