Is it possible to save decoded data to file?

[MeganeRoppy]

This asset nicely works, but we would like to make its decoding time shorter.
Then we wonder if it's possible to save decoded data to local storage then makes it ready for immediate play.
We think it's no doubt possible to save that decoded sequential Texture2Ds then load and play, but we would like to know if there's more assumed procedure.

Thanks.
