Video Reflection？

Hi，I need some help on reflection. What I want to achieve is to be
able to reflect the moving environment, like panorama content to be
able reflect on 3D meshes (Just lights not like mirror effect in the
example of physical material) .
I found the new version allows me to use HDR file instead of the
cube map. However, I need a video instead of a picture. Is there
anyway to do so? Or, does it possible to make similar effect by using
the shader for the materials? Let me know if it has any example to
make such effect.

Thank you so much :)
