ubuntu 安装VLC后无法播放_ubuntu系安装vlc之后播放页面没有画面

按照如下方式安装VLC:

安装vlc方法
sudo apt-get update
sudo apt-get install vlc
sudo apt-get build-dep vlc

安装后无法打开VLC，报如下错误：

VLC is not supposed to be run as root. Sorry.
If you need to use real-time priorities and/or privileged TCP ports
you can use ./vlc_back-wrapper (make sure it is Set-UID root and
cannot be run by non-trusted users first).

使用以下三个命令：
cp /usr/bin/vlc /usr/bin/vlc-backup
needle=$(objdump -d /usr/bin/vlc | grep euid | tail -1 | awk '{print "\\x"$2"\\x"$3"\\x"$4"\\x"$5"\\x"$6;}')
sed -ir "s/$needle/\xb8\x01\x00\x00\x00/" /usr/bin/vlc

就可以播放了。
