Oculus Quest 2 connect with 360 camera Theta S

Good morning, I'm Marco From Italy. Thank you about your valuable support.

I've got an Oculus quest 2.

I would connect my oculus quest 2 with the HDMI signal from my camera 360 ricoh Theta S.

I'm able to connect the Camera theta to the pc monitor with hdmi cable and I'm able to see the video (there are 2 circles, front and rear camera).

I would like to know what I need to do in order to see the live 360 ​​video (without internet) directly in the oculus.

Thank you in advance and sorry about my English.

Bye Marco
