How to install libx265 for ffmpeg on Mac OSX
Solution 1
Try using --with-x265
instead of --enable-libx265
as described in the official FFmpeg wiki. https://trac.ffmpeg.org/wiki/CompilationGuide/MacOSX
Those guides you linked to are not specifically for homebrew, which is why they used --enable
instead of --with
.
Solution 2
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

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 ran
brew install ffmpeg --with-fdk-aac --with-freetype --with-libass --with-libvpx --enable-libx265
No matter what when I go to run a command like
ffmpeg -i source.mkv -c:v libx265 test1.mkv
I get the error:
Unknown encoder 'libx265'
Has anyone had success building libx265 for use with ffmpeg on OSX and can you please share how you did it?
P.S. I am running OSX 10.11.3
