debian 12 编译 vlc/libvlc 支持 rtsp

debian 官方从11开始，不再提供支持 rtsp 的 VLC deb 包，通过 libvlc 播放 rtsp 也无法实现，因此需要自己编译。

# 安装编译环境，编译依赖库以及 contrib 第三方工具

sudo apt install git g++ make libtool automake autopoint pkg-config flex bison lua5.2
sudo apt build-dep vlc
sudo apt install subversion yasm cvs cmake ragel

建议添加阿里云的镜像源

sudo nano /etc/apt/sources.list.d/aliyun.list

# 添加 debian 阿里云源到 /etc/apt/sources.list

sudo apt update

# 下载 vlc 源代码，解压

wget http://download.videolan.org/pub/videolan/vlc/3.0.21/vlc-3.0.21.tar.xz
tar xvJf vlc-3.0.21.tar.xz
cd vlc-3.0.21

# 创建编译目录

cd contrib
mkdir native && cd native
../bootstrap

# 下载 live555 源代码并编译，注意不是 live555 的最新版本，而是 videolan 提供的特定版本

wget http://downloads.videolan.org/pub/contrib/live555/live.2016.11.28.tar.gz -O ../contrib/tarballs/live.2016.11.28.tar.gz
make .live555

# 配置 vlc 的编译参数，关键是指定安装位置，以及启用 rtsp，其他可选参数还有 --disable-alsa --disable-chromaprint --enable-shared 等, 开始编译

../../configure --prefix=/usr --enable-realrtsp --enable-live555
make

# 编译完成后，查看是否已支持 live555

./vlc --list | grep live555

# 安装

make install

# 如果未安装在 /usr 下，想引用 libvlc 需要自己添加环境变量。也可以修改 /etc/ld.so.conf 或添加 /etc/ld.so.conf.d/libvlc.conf，填写"自定义的安装目录/lib"，然后执行

sudo ldconfig
