3D metadata injector

I have a 3D 180 camera (QooCam). On my old mac there was a program that allowed you to edit video clips and export them and would automatically add the 3D metadata so clips could up uploaded to YouTube. That program in not compatible with Linux so I need a new metadata injector software that specifically will that the spherical video and add the 3D metadata to the clip. Any suggestions?

You could try DigiKam.
