A tool & C# library to parse DCPs (Digital Cinema Package)
- Load your DCP
Select the DCP you want to load
- Check if you need a KDM
If a KDM is required, this message will be displayed
If a KDM is not required, this process is already complete, see #5
- Load your KDM
Select the KDM you want to load
If the KDM is correct, it will show as Unlocked in the Rights Management panel
- Done
Once a DCP (and optionally KDM) is loaded, you will then be able to see information about your DCP/KDM in their respective panels
