Just Play Lite NDI · 2026 documentation

Known Issues - Just Play Lite NDI (v.2026.x)

Apple Magic Mouse

The Apple Magic Mouse (all colours) is not compatible with the Just Play user interface. Especially clicking on an existing playlist inside the CalendarView is not possible and therefore we highly recommend not to use another mouse or trackpad.

SMB issues using some versions of macOS

Some versions of macOS behave very slowly while connected to a shared storage using SMB. Please execute the following Apple Terminal commands on all Macs running ToolsOnAir playout software to disable SMB 1, which can improve the behavior:

echo "[default]" | sudo tee -a /etc/nsmb.conf

echo "protocol_vers_map=6" | sudo tee -a /etc/nsmb.conf

Duplicate Names in Repository Folders

Defining two Repository folders that contain a file with the same name creates a problem. The playout engine will find the file in the Repository folder that is defined first, even if you dragged the file from the Repository folder defined second in Just Play Lite NDI. Example: in the “Just Play Lite NDI Configuration → Repositories” panel, you can define two folders, one called “SD” and the other “HD” (in that order). In the Just Play Lite NDI application, you drag a video clip called “movie.mov” from the “HD” folder into the timeline. If there is also a video clip called “movie.mov” in the “SD” folder, the Just Out engine will play the file from the “SD” folder because it is defined before the “HD” folder.

Broken Video Files

It is important to make sure that all files that should be played out are supported and can be played out. An unlicensed (trial) version of Just Play Lite NDI running on another Mac can be used to test new files. Please verify that the machines are absolutely the same (hardware and software). Ensure that all movies are available if reference movies should be used. Trying to play out faulty or unsupported movies can harm the final output and even crash the playout engine.
