The .find() and .children() methods are similar, except that the latter only travels a single level down the DOM tree.

aws ubuntu 에 ffmpeg 설치가 필요했다.
ubuntu 버전은 14.04


1. 컴파일 설치
https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu 참조
이대로 진행 하려고 하다가 귀찮아서..


2. apt-get 설치
https://www.ffmpeg.org/download.html 에서 링크를 타고

https://launchpad.net/~mc3man/+archive/ubuntu/trusty-media 로 이동해보니 방법이 쭉 나와있다

sudo add-apt-repository ppa:mc3man/trusty-media
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install ffmpeg



순서대로 진행하면 완료~




- ubuntu ffmpeg install
- apt-get install ffmpeg
- E: Package 'ffmpeg' has no installation candidate
