版权的原因，群晖的Video Station已经无法直接播放带有DTS、EAC3、TrueHD等编码格式的视频
网上也有不少解决方法，不过都是相对时间久远，
替换VideoStation中自带的ffmpeg解码器，完美播放
我综合了一下做法，分享给大家
本方法适用最新版的（2020年10月）Video Station 2.4.9-1626，
基于黑群晖 DS3617xs DSM 6.1.7-15284 Update 3 测试成功
但是在DS981+安装的话，需要把Video Station设置里面的硬件加速打勾去掉
1、安装ffmpeg解码器
在群晖套件中心设置，新增套件来源，名称随意，位置：http://packages.synocommunity.com
社群-安装ffmpeg，如果下载缓慢，可以用出国留学线路
2、安装VideoStation
在套件中心安装Video Station，我安装的是Video Station版本为2.4.9-1626
3、开启ssh并获取root权限
控制面板-终端机和SNMP-启动SSH功能，用XSheell软件或者putty软件，用root用户以SSH的方式登录到群晖
开启root，看教程开启：https://www.itxiaoniao.cn/archives/397/
然后执行下面命令，逐行执行：
1）调整文件权限
sudo chmod +s /var/packages/ffmpeg/target/bin/ffmpeg
sudo chmod +s /var/packages/ffmpeg/target/bin/ffprobe
sudo chmod +s /var/packages/ffmpeg/target/bin/vainfo
2、备份原文件
sudo sed -i'-BACKUP' -e 's/eac3/ZAAP/' -e 's/dts/ZAP/' -e 's/truehd/ZAPZAP/' /var/packages/VideoStation/target/lib/libsynovte.so
sudo mv /var/packages/VideoStation/target/bin/ffmpeg /var/packages/VideoStation/target/bin/ffmpeg-BACKUP
sudo mv /var/packages/VideoStation/target/bin/ffprobe /var/packages/VideoStation/target/bin/ffprobe-BACKUP
sudo mv /var/packages/VideoStation/target/bin/vainfo /var/packages/VideoStation/target/bin/vainfo-BACKUP
3、更改/var/packages/VideoStation/target/ffmpeg为自定义脚本，调用第三方的ffmpeg解码器

4、更新ffprobe vainfo
sudo ln -s /var/packages/ffmpeg/target/bin/ffprobe /var/packages/VideoStation/target/bin/ffprobe
sudo ln -s /var/packages/ffmpeg/target/bin/vainfo /var/packages/VideoStation/target/bin/vainfo
5、解除对EAC3、DTS、TrueHD的屏蔽
sudo sed -i'-BACKUP' -e 's/eac3/ZAAP/' -e 's/dts/ZAP/' -e 's/truehd/ZAPZAP/' /var/packages/VideoStation/target/lib/libsynovte.so
6、再次调整文件权限
sudo chmod +x /var/packages/VideoStation/target/bin/ffmpeg
sudo chmod +s /var/packages/VideoStation/target/bin/ffmpeg
sudo chown root:VideoStation /var/packages/VideoStation/target/bin/ffmpeg
完成，播放测试
