I am new to the forum, sorry if I make some errors and for my english. Some days ago I read a lot of video surveillance. I immediately marked Zoneminder that seems to be the best open source program available on web. I decided to install everything on Arch Linux distribution that I consider lightweight with high performance and there is a lot of documentation if I need. I installed the GIT version present in AUR, all okay no errors. When I connected my WEB CAM for test, has started the problema. I can not understand the error, I tried everything but nothing, probably the solution is simple but my continuous attempts and failures probably don't see it. Probably some of you has happened this error and can help me show the way of the solution.
Situation :
