I just want to share this amazing script, called media-autobuild_suite, that makes it extremely easy to build the ultimate media/encoding suite. It will automatically download MinGW and allow you to build things like FFmpeg, x264 10-bit, x265 10-bit, mpv, MPlayer, mp4box, MediaInfo CLI, etc. It also lets you choose what encoders you want to build for FFmpeg and if you want non-GPL encoders built in, such as libfdk-aac (the highest quality AAC encoder in FFmpeg). It also provides a way to build new versions when updates are available.
All you do is run the batch script included and it’ll ask you what you want to build. It doesn’t take long to choose everything and it only took me a little over an hour to build everything I wanted.
Take a look at the link above to check out what all it can build and follow the instructions on that page to use it. I use FFmpeg to encode all my videos and audio, so this was the perfect solution. I hope this helps anyone that has attempted to build their own FFmpeg and/or other tools.
