Hi!
Is possible to use two or three webcams connected via USB 2.0 or 3.0 in a notebook or desktop and use with Vmix to streaming production?
I have three Logitech 720p and I would like to use them with Vmix, but my doubts are if there any issue about quality, latency or audio delay... I know already about to check YUY2 or Mjpeg but, there is more about it?

Thank you so much!

Yes. I recently did an experiment using 4 USB cameras with a single host PC.

https://www.mgraves.org/...ms-on-a-single-computer/

- All configured for 1080p30 using MJPEG
- In a 4K vMix project.
- 3 cameras were connected to a USB 3 hub, onward to a USB 3.0 port on the host.
- The 4th was connected to a USB port on the host.
- Connecting all 4 to the hub was unstable.

Using MJPEG introduces no additional latency.

Wow! Thank you so much! Great to know that!
And about audio? I would like to connect 3 mics through audio mixer Behringer on audio input of notebook or desktop but, there any delay audio issues? Because I don't want to use the mic intern of webcams. Is that possible with delay issues?

If the audio follows a different path there will likely be some issue with sync. vMix makes it pretty easy to delay signals, so you can adjust the audio source to be in sync with the video. The video is always late.
