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

 # 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

?

1 2	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

?

1 2	../../configure --prefix=/usr --enable-realrtsp --enable-live555 make

  # 编译完成后，查看是否已支持 live555

?

1	./vlc --list | grep live555

 # 安装

?

1	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

?

1	sudo ldconfig
