Debian7下安装和卸载FFmpeg

一、添加其他源安装ffmpeg

如果你已经通过默认源安装了请先看第二步卸载

echo 'deb http://www.deb-multimedia.org wheezy main non-free' >> /etc/apt/sources.list
wget http://www.deb-multimedia.org/pool/main/d/deb-multimedia-keyring/deb-multimedia-keyring_2016.8.1_all.deb
sudo dpkg -i deb-multimedia-keyring_2016.8.1_all.deb
rm deb-multimedia-keyring_2016.8.1_all.deb

更新一下数据

apt-get update

如果更新过程中报：GPG error: http://www.deb-multimedia.org wheezy Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 等错误则执行

更新：最近在debian7下安装时此处没有报错，还是没有安装成功。但是进行一下步骤后就成功了。

apt-get install deb-multimedia-keyring

然后开始安装依赖

apt-get install curl python-software-properties software-properties-common
apt-get install ffmpeg gstreamer0.10-ffmpeg

这下在debian 7下ffmpeg就安装好了

二、卸载ffmpeg

apt-get -q -y remove --purge ffmpeg gstreamer0.10-ffmpeg
apt-get autoremove
apt-get autoclean
apt-get clean
