3. The homebrew's opened a PR on fceux but also wrong and no maintainer response it

4. The VLC implement the compatibility with the new API

Currently, I suggest to not to upstream to fceux itself. Not only because that I would like to waiting for upstream discussing it, maybe including increasing the efficiency by making use of the new API instead of simply handle it, but also the x265's said that just in the original commit session:

Hi, we are working on preserving the old API(x265_encoder_encode) and we shall be making a minor release (v4.1) with those changes shortly.
