Modification of AJA and BlackMagic plugins

Hi everyone.

Right now we’re trying to add several new features for the frame processing on UE side. For this purpose we want to modificate plugins below:

But It seems that most of the plugins core logic is located in locked dll. files. Does anyone know how can we access a source code? We also ready to do all the changes through support if this option is preferable. Maybe someone here has direct connection to the developers. Any help will be much appreciated.

Regards,
Eugene
