I guess the next step here is a video encoder that is natively recording spherical videos ?

Any projection is bound to separate areas which could be compressed more efficiently together.

A native stereoscopic spherical video encoder could improve compression even more, since side by side views are quite similar in general.

Now that's an interesting problem to solve ! (and a very hard one probably)

Existing video formats already support this for interlacing, although you could also let inter-prediction refer to earlier parts of the same frame and get most of the benefit.

It is developed in the mpeg standard already, there is a whole group of people for that from some years ;)
