Introduction

OBS VNC Source is a VNC viewer integrated into OBS Studio. You can use this plugin to stream a desktop on your external computer.

Pros and Cons

Compared to other protocol such as NDI, VNC has such benefits.

• Pros to use OBS VNC Source
  • Lightweight in terms of CPU usage on both server and client side.
  • MacOS has built-in VNC Server.
  • Small traffic for static contents such as text and images.
  • Built-in interaction to control mouse and keyboard.
  • No accumulated lags, just rendering when the new frame arrives.
• Cons
  • Audio is not supported in VNC.
  • Quality is not stable. If network connection becomes slow, quality will be reduced.
  • Latency is not stable. The frame will be displayed as it arrives to the viewer. There could be a jitter.

If you are sharing movies or graphical games, I don't recommend VNC.
