You can apply the video to a sphere with normals pointing inwards. Here's an example:
Code:
import viz
import vizshape
viz.go()
video = viz.addVideo('sphericalVideo.mp4')
sphere = vizshape.addSphere(flipFaces=True)
sphere.texture(video)
#Play and loop the video
video.play()
video.loop()
#Make sure sphere appears at infinite distance
#This allows other objects to be rendered in front
sphere.disable(viz.DEPTH_TEST)
sphere.drawOrder(-100)
#Keep sphere centered around main view
viz.link(viz.MainView,sphere,mask=viz.LINK_POS)
#Setup a panorama camera navigation
import vizcam
vizcam.PanoramaNavigate()
