群暉公司由于版權(quán)的原因，群暉自帶的Video Station無(wú)法播放帶有DTS、EAC3、TrueHD等編碼格式的視頻文件，嚴(yán)重影響使用效果。本文將利用第三方的ffmpeg替換VideoStation中自帶的ffmpeg解碼器，完美播放帶有DTS、EAC3、TrueHD等編碼格式的視頻，實(shí)現(xiàn)對(duì)全視頻格式的支持。

一、安裝ffmpeg解碼器

1、在群暉套件中心，設(shè)置，套件來(lái)源，新增，名稱(chēng)（任意寫(xiě)），位置：http://packages.

        如果按照上述方法不能正常安裝ffmpeg套件的，可以到這個(gè)地址：https://github.com/th0ma7/synology/tree/master/packages
        請(qǐng)根據(jù)自己的CPU架構(gòu)下載對(duì)應(yīng)的ffmpeg安裝包，上傳到群暉的套件中心安裝，目前常見(jiàn)的構(gòu)架有：

（1）DS918+的CPU架構(gòu)是apollolake

（2）DS3617xs的CPU架構(gòu)是broadwell

（3）DS3615xs的CPU架構(gòu)是bromolow

        其他的CPU架構(gòu)與之對(duì)應(yīng)的版本可以在這查詢(xún)：https://github.com/SynoCommunity/spksrc/wiki/Architecture-per-Synology-modelffmpeg

二、安裝VideoStation
       在套件中心安裝Video Station，本文安裝的Video Station版本為2.4.7-1603。

三、我們先來(lái)測(cè)試一下沒(méi)修改之前，用Video Station播放帶有DTS和EAC3編碼的視頻文件，會(huì)是怎樣的

這個(gè)是帶EAC3編碼的視頻文件

用Video Station播放EAC3編碼的界面提示

這個(gè)是帶DTS編碼的視頻文件

用Video Station播放DTS編碼的界面提示

四、用第三方的FFMEG代替

       進(jìn)群暉的控制面板，終端機(jī)和SNMP，勾選啟動(dòng)SSH功能，并調(diào)整對(duì)應(yīng)的端口號(hào)。然后到電腦上打開(kāi)XSheell軟件，用root用戶(hù)以SSH的方式登錄到群暉（還沒(méi)開(kāi)啟root的，請(qǐng)自己去開(kāi)啟：https://wp./?s=root），執(zhí)行以下命令：

1、調(diào)整文件權(quán)限

sudo chmod +s /var/packages/ffmpeg/target/bin/ffmpegsudo chmod +s /var/packages/ffmpeg/target/bin/ffprobesudo chmod +s /var/packages/ffmpeg/target/bin/vainfo

2、備份原文件

sudo sed -i'-BACKUP' -e 's/eac3/ZAAP/' -e 's/dts/ZAP/' -e 's/truehd/ZAPZAP/' /var/packages/VideoStation/target/lib/libsynovte.sosudo mv /var/packages/VideoStation/target/bin/ffmpeg /var/packages/VideoStation/target/bin/ffmpeg-BACKUPsudo mv /var/packages/VideoStation/target/bin/ffprobe /var/packages/VideoStation/target/bin/ffprobe-BACKUPsudo mv /var/packages/VideoStation/target/bin/vainfo /var/packages/VideoStation/target/bin/vainfo-BACKUP

3、更改/var/packages/VideoStation/target/ffmpeg為自定義腳本，調(diào)用第三方的ffmpeg解碼器（命令已經(jīng)更新，下圖為之前的截圖，命令有區(qū)別請(qǐng)忽略）

4、更新ffprobe vainfo

sudo ln -s /var/packages/ffmpeg/target/bin/ffprobe /var/packages/VideoStation/target/bin/ffprobesudo ln -s /var/packages/ffmpeg/target/bin/vainfo /var/packages/VideoStation/target/bin/vainfo

5、解除對(duì)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、調(diào)整文件權(quán)限

sudo chmod +x /var/packages/VideoStation/target/bin/ffmpegsudo chmod +s /var/packages/VideoStation/target/bin/ffmpegsudo chown root:VideoStation /var/packages/VideoStation/target/bin/ffmpeg

五、接下來(lái)我們?cè)儆肰ideo Station來(lái)播放剛才未能播放的文件做一下測(cè)試

1、DTS播放正常

2、EAC3播放正常

六、非常完美！
