Noted.
btw can we get something that works with full bitstream too ?
This patchset actually support the full bitstream too, unfortunately it is blocked by hardware MPFE issue. The patchset for the MPFE workaround would come after this patchset. I would advice to use the early IO release method for the sake of performance.

Does that work on ES2 ? I don't think so ...
Why you think it doesn't work, using early IO or full rbf? The bitstream limitation? What you see from the print out?
ES2 can only use full RBF, I don't think this is handled in this patchset at all.
