Pine64 accelerated H.264 encoding

[MarkHaysHarris777]

do you think that in the future there will be linux hw acceleration?
the orange pi is another board that is very similar in that it has mali gpu and they have hw acceleration 

thanks

No, not for the PineA64 board; not in the near future.

But would it be theoretically possible to take some parts of a git repo and build your own image with the graphics-bits from an SBC with a similar SoC?

No.

... Simon (longsleep) has estimated that it would take two 'paid' serious developers 1.5 person years to reverse engineer the proprietary code and subsequently build the open product that would serve the community effort. This is not going to be a trivial effort , nor is it going to be a successful trial and guess accomplishment either.
