What the Mali400MP2 says it can do and what the supporting 'blob' from the IC vendor does appears to be different.

You should start to become familiar with the basics. Mali400 has nothing to do with video encoding/decoding.

Therefore the situation with a new Allwinner SoC regarding video encoding/decoding is the same as with every other Allwinner SoC: Don't expect that it will work (in Linux). Especially since documentation regarding A64 is still lacking.
