I'm interested in using all kinds of devices for streaming live video from live (think music) events via OBS with minimal effort. Current setup is with a device (just an old iPhone can do) which provides WiFi connectivity, then another (or the same device) runs DroidCAM which them streams into a nearby laptop with OBS (typically capturing the audio needed) and this is then sent to wherever we decide (twitch, RSTP, etc). We've tried this setup with as many as three droidcam phones, and it is just fine on... a legacy MacBook Pro with Intel + 1500MB Iris card.
So ideally I'd imagine getting a second-hand 600D or 200D and having a similar setup. We did have a setup (previously) where a GoPro or mini-HDMI campera is captured and then processed by a RBPi 2/3/4, but this seems an overkill compared to the DroidCAM Setup.
And, of course, the optics on the 600D/200D are expected to be much more correct than those on an iPhone or similar phone/mobile device.
Thanks for your kind attention.
