FAQ

The camera does not work

• Select UE4 media player in Select camera control framework
  • Try selecting different formats in "Image size"
• Select Direct Show in Select camera control framework
  • Select proper image size based on the camera specification

If none of these work, unfortunately MocapForAll will not be able to use the camera.

Multiple cameras of the same model are not recognized

When connecting multiple cameras of the same model to a PC, there is a problem that some of them are not displayed (not detected) in the pull-down of camera selection in the app. In that case, try setting an arbitrary FriendlyName from the registry editor to the camera device that is not displayed.
The method of setting / changing the FriendlyName differs depending on your environment, so please google it yourself. Since you are editing the registry, it is recommended to make a backup.
