Hi,
I tried it few days ago and it works perfectly with minimal latency (cca 150 ms). I used Wifi Webcam Forever sc-220 as a streamer and made a patch in TouchDesigner MovieStreamIn (with correct IP adress and stream name - in my case it was rtmp://192.168.0.1/MJPG) > SpoutOut...In resolume you just put a spout cam...It works nice, but TouchDesigner is little hardware demanding sw...since 2 months it is downloadable also for MacOS...just use SyphonOut insttead of SpoutOut node....enjoy.
But anyway it is a complicated way to do that...do you have any suggestions, how to do it easier? Thx.
