群暉DSM7.0 VideoStation 支持 DTS、EAC3 等專利音軌的方法補充

安裝調用第三方 ffmpeg

參考 此篇博客 安裝 ffmpeg^[1] 並執行相關命令。

在 DSM6 的時候，通過此方法就可以完美解決問題了，但是在 DSM 更新到 7.0 之后，據說因為 Advanced Media Extensions 的存在，導致第三方 ffmpeg 被阻止，從而出現 DTS 等音軌視頻無法播放的問題。目前網上能搜到的方法基本就是建議卸載 Advanced Media Extensions 並安裝低版本 VideoStation。個人不太喜歡舊版本的軟件，所以還是希望能有不降級的方法。好在前述博客中提到了 ffmpeg 的日志位置，通過查看日志，發現，在播放DTS等格式的視頻時，所有調用第三方 ffmpeg 等過程都正常，只是在最后提示Permission Deny 猜測可能是權限的問題，於是查看 /var/packages/ffmpeg/target/bin/ffmpeg 相關權限，發現其用戶和組權限是 sc-ffmpeg synocommunity 於是將權限分別更改為 root VideoStation 命令如下：

chown root:VideoStation /var/packages/ffmpeg/target/bin/ffmpeg

然后測試相關視頻成功。

文本提到相關軟件版本：

DSM: 7.0-41890

VideoStation: 3.0.1-2067

ffmpeg: 4.3.2-38
