I'm trying to replicate the following command in OSX:
sudo modprobe v4l2loopback video_nr=3 card_label="TestVideo"
So far I've tested the following advice here but I keep getting an error erroneous pipeline: no element "videotestsrc"
My first question is are the two commands v4l2loopback=gst-launch-1.0 equal?
My second question is whether there any ways to use v4l2loopback in OSX?
