原文: https://zhuanlan.zhihu.com/p/393311059

1. 安装ffmpeg 套件中心->设置->套件来源->新增 http://packages.synocommunity.com/ 国内源: https://spk7.imnks.com/ 搜索安装ffpmeg

2. 通过SSH连接群晖,并输入sudo -i切换至root用户模式(Tips:SSH需要进入控制面板->终端机和SNMP->终端机->启用SSH功能)

3. 依次执行以下内容脚本

   #备份 VideoStation's ffmpeg
   mv -n /var/packages/VideoStation/target/bin/ffmpeg /var/packages/VideoStation/target/bin/ffmpeg.orig
   #下载ffmpeg脚本
   wget -O - https://gist.githubusercontent.com/BenjaminPoncet/bbef9edc1d0800528813e75c1669e57e/raw/ffmpeg-wrapper > /var/packages/VideoStation/target/bin/ffmpeg
   #设置脚本相应权限
   chown root:VideoStation /var/packages/VideoStation/target/bin/ffmpeg
   chmod 750 /var/packages/VideoStation/target/bin/ffmpeg
   chmod u+s /var/packages/VideoStation/target/bin/ffmpeg
   # 备份VideoStation's libsynovte.so
   cp -n /var/packages/VideoStation/target/lib/libsynovte.so /var/packages/VideoStation/target/lib/libsynovte.so.orig
   chown VideoStation:VideoStation /var/packages/VideoStation/target/lib/libsynovte.so.orig
   # 为libsynovte.so 添加 DTS, EAC3 and TrueHD支持
   sed -i -e 's/eac3/3cae/' -e 's/dts/std/' -e 's/truehd/dheurt/' /var/packages/VideoStation/target/lib/libsynovte.so
   #备份CodecPack的ffmpeg41 这两端命令行重要 很多文章/脚本都缺少这两个命令行
   cp /var/packages/CodecPack/target/bin/ffmpeg41 /var/packages/CodecPack/target/bin/ffmpeg41.bak
   #链接ffmpeg解码模块
   cp /var/packages/VideoStation/target/bin/ffmpeg /var/packages/CodecPack/target/bin/ffmpeg41
   

4. 重新启动Video Station，让ffmpeg与Video Station的关联生效

5. 如何还原和卸载?

   #恢复之前备份的 VideoStation's ffmpeg, libsynovte.so, ffmpeg41文件
   mv -f /var/packages/VideoStation/target/bin/ffmpeg.orig /var/packages/VideoStation/target/bin/ffmpeg
   mv -f /var/packages/VideoStation/target/lib/libsynovte.so.orig /var/packages/VideoStation/target/lib/libsynovte.so
   mv -f /var/packages/CodecPack/target/bin/ffmpeg41.bak /var/packages/CodecPack/target/bin/ffmpeg41
