ffmpeg downgrade?

Yxzx presumes this:
// The NVN driver buffer (index 0) is known to pack the SSBO address followed by its size.
But in MCI i`ve discovered that there are no sizes, both registers are GPU addresses (hence the 2.8gb allocation, it was an address actually)

Method could be much simpler but for safety i`ve routed both old and new worlds.
