That one is quite easy
init_scene:
copy webcam code from geexlab_code_sample_pack/host_api/webcam/webcam_win32_spout_test.xml ( the other demos didn't work on my rig for some reason)
rename tex01 to webcamtex to avoid confusion
and don't forget (like me in first place) to add
quad = gh_mesh.create_quad(winW, winH)
shadertoy_prog = gh_node.getid("shadertoy_prog")
update_scene:
gh_texture.bind(webcamtex, 0)
gh_utils.webcam_grab_frame(webcam1)
gh_utils.webcam_update_texture(webcam1, webcamtex)
gh_gpu_program.uniform1i(shadertoy_prog, "iChannel0", 0)
That's all.

Thanks for the effect!

I think it's because the demo tries to connect to the second webcam. Look for the following line in the INIT script:
gh_utils.webcam_start(webcam1, 2)
and replace it by:
gh_utils.webcam_start(webcam1, 1)
I have two webcams on my system and I forgot to update the demos.

Yes, that was the culprit.
I quickly converted some video demos to webcam demos.
Hail to the clipboard :P
