I’m trying to get the camera angles with libvideo-metadata (Getting camera pose with libvideo-metadata) but I’m not very familiar with these notions and I don’t get any coherent data.
Can you give some clarifications please :
In vmeta_frame, what is frame_view_quaternion ? How do I get the camera angles from it ?
Also when I define some vmeta_euler, apply vmeta_euler_to_quat and then reapply vmeta_quat_to_euler, I don’t get the same angles, can you tell me why and what conventions are used ?
Thank you very much
