I have tried multiple guides here (search for \"Building libx265\") and here with no success. Both times I made sure I uninstalled ffmpeg first, went through the guides, then r
Seems like you can't just do brew install ffmpeg --with-x265
anymore (this is Oct 2019). What worked for me is this:
brew tap homebrew-ffmpeg/ffmpeg
brew install homebrew-ffmpeg/ffmpeg/ffmpeg
This is from https://github.com/homebrew-ffmpeg/homebrew-ffmpeg. It says the default already includes x265, but you can then optionally pass some arguments like
brew install homebrew-ffmpeg/ffmpeg/ffmpeg --with-xvid --with-fdk-aac
You can take a look at what options are available by doing
brew options homebrew-ffmpeg/ffmpeg/ffmpeg
