Open Broadcaster Software

You will be able to stream on MyFreeCams.com using OBS or other RTMP External Broadcasters (XSplit, Wirecast, ManyCam, etc).

Currently, streaming via OBS is beta and models may experience occasional connection instability. We are working to resolve the final issues and add more servers before officially launching support for OBS in the coming weeks.

After launch, we will provide instructions, support, and plugins to make OBS easier to use.


Minimum Recommended
Processor Intel i5 or AMD 6-core Intel i7 or AMD 8-core
Internet 4+ Mbps upload bandwidth 6+ Mbps upload bandwidth
Memory 4 GB RAM 8+ GB RAM
OS Windows 7 SP1 / macOS 10.11 Windows 10 / macOS 10.13+
Graphics DirectX 10.1 / OpenGL 3.2 GPU DirectX 10.1+ / OpenGL 3.2+ GPU

A hard-wired Ethernet connection is strongly recommended (rather than WiFi)

Windows 10 users: If you have received the Windows 10 1809 update, make sure that Game Mode is disabled (PC Settings / Gaming). If Game Mode is enabled, Windows reduces GPU priority for OBS, which can cause frame lag in your stream.

Video Preview

Obs windowed projector settings.png

When using OBS, the video preview in the Model Web Broadcaster is disabled and will show "LIVE" when broadcasting. Here's an alternative method to placing OBS alongside your web browser:

  • In OBS, click Settings and select the General tab. In the Projectors section select Make projectors always on top and Save projectors on exit
  • Right click the video preview in OBS and select Windowed Projector (Preview)
  • Drag the Windowed Projector to the top left corner of the Model Web Broadcaster (or anywhere) and resize as desired

Having two previews turned on may result in missed frames due to rendering delays. To prevent this:

  • Right click the video preview in the main application and select ✓Enable Preview to disable the preview
