You can use ffmpeg either by installing or just by downloading.

Type these cmd in your terminal.

1. install homebrew

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2. install ffmpeg

brew install ffmpeg

https://ffmpeg.org/ Or: https://raw.githubusercontent.com/fashare2015/gradle-screen-record/master/ffmpeg

If you just download the ffmpeg instead of installing it, you must set the path of it. Add the path of ffmpeg this way:

Config in rootProject/gradle.properties:

FFMPEG_PATH=XXX

For example: FFMPEG_PATH="./ffmpeg"
