To resolve this error, right click on the project in the left menu of eclipse and choose “properties”

Select Run/Debug Settings on the left, highlight the launch configuration and click “Edit” on the right

Select the “Arguments” tab and ensure the following line is added to the list:

For Windows ‐Dcom.wowza.wms.native.base=“win”

For Mac ‐Dcom.wowza.wms.native.base=“osx”

Click ok
