Ubuntu 20.04.4 LTS에서 ffmpeg 설치 하는 방법(Unknown encoder 'libfdk_aac')

개요 (Overview)

Ubuntu 20.04.4 LTS에서 ffmpeg 설치 하는 방법

Ubuntu에서 sudo apt-get install ffmpeg 로 ffmpeg를 설치할 수 있지만 'libfdk-aac'가 없어서 디코딩을 못한다거나
커스텀한 설정이되지 않아 인코딩이나 디코딩이 되지 않을 수 있다

본인의 경우 인코딩시 Unknown encoder 'libfdk_aac' 모듈을 찾으면서 오류가 발생해서 기존에 설치된 ffmpeg를 제거하고
아래의 명령어로 ffmpeg를 설치해서 문제를 해결하였다

cd ~/ffmpeg_sources
wget http://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2
