Ubuntu14.04でffmpegをPPAからインストール

More than 5 years have passed since last update.

ffmpeg、ビルドしたりするの面倒くさい。
PPAパッケージ公開されてるので簡単インストール。

$ sudo add-apt-repository 'deb http://ppa.launchpad.net/jon-severinsson/ffmpeg/ubuntu '"$(cat /etc/*-release | grep "DISTRIB_CODENAME=" | cut -d "=" -f2)"' main' && sudo apt-get update

「GPG鍵ない」と怒られる
bash
W: GPG エラー: http://ppa.launchpad.net trusty Release: 公開鍵を利用できないため、以下の署名は検証できませんでした: NO_PUBKEY 1DB8ADC1CFCA9579

なので鍵を追加してからインストール

$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys  1DB8ADC1CFCA9579
$ sudo apt-get install ffmpeg

わーい
