Nice plugin! Sadly, it doesn't work for me.
I exported your example as HTML5 (to be perfectly clear, I didn't change anything in the capx) and runned it on Chrome and Firefox, and the camera is never recognized. The UserMedia object stays black even when pressing "open" or any other button.
Tested on Chrome on a Huawei P8 Lite (phone, not tablet) with android 5.0.1
and on iPad Air 2 with Chrome v.58.0.3029.83 and Safari
Then I exported to android via Phonegap, installed the app on my cell phone (Android, Huawei P8 Lite), and the UserMedia object still stays black at all times.
When building via Phonegap, I unchecked "minify script", and checked "uses camera" and "uses media" under permissions.
Any idea about what I'm doing wrong?
Something to define in Phonegap Build maybe?
