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?

My first question is are the two commands v4l2loopback=gst-launch-1.0 equal?

no. they are not.

  • gst-launch-1.0 is a command that launches a GStreamer pipeline (as specified by its arguments). GStreamer is a generic, cross-platform media framework
  • v4l2loopback is not a command at all.

My second question is whether there any ways to use v4l2loopback in OSX?

no.

the v4l2loopback (which is an abbreviation for "video for linux (version 2) loopback") integrates tightly with the linux kernel. the kernel is the core component of your operating system. a Linux kernel is not compatible with a Darwin kernel (which is what runs your OSX)
