Black群晖VideoStation不支持音频 DTSEAC3TureHD的解决办法

前几天自己手贱，更新了VideoStation，更新完又回到不支持 DTS格式的情况，之前修复的方法又没做笔记，所以这次把笔记做好，防止下次！

1、安装或更新完VideoStation后，接着安装ffmpeg（我安装的是4.4.4.49），再安装Media Extensions；

2、停用VideoStation；

3、到控制面板里面打开ssh；

4、用电脑ssh远程连接到群晖上；

5、获取su权限sudo -i，输入后回车再输一次密码；

6、依次执行以下命令：如果第二条命令执行失败，请看完解决办法后再继续执行下面的几条命令。

#重名备份ffmpeg41为ffmpeg41.orig
mv /var/packages/CodecPack/target/pack/bin/ffmpeg41 /var/packages/CodecPack/target/pack/bin/ffmpeg41.orig
# 这里可能因为无法访问 github 失败，下面又解决办法，请看完再继续下面的命令
wget -O - https://raw.githubusercontent.com/Rootjhon/Synology_Enhance/main/VideoStation/DSM7_1/ffmpeg41-wrapper > /var/packages/CodecPack/target/pack/bin/ffmpeg41
#修改ffmpeg41 权限
chmod 755 /var/packages/CodecPack/target/pack/bin/ffmpeg41
#重名备份libsynovte.so 为libsynovte.so.orig
cp -n /var/packages/VideoStation/target/lib/libsynovte.so /var/packages/VideoStation/target/lib/libsynovte.so.orig
#修改libsynovte.so.orig的用户组权限
chown VideoStation:VideoStation /var/packages/VideoStation/target/lib/libsynovte.so.orig
#设置解码
sudo sed -i -e 's/eac3/3cae/' -e 's/dts/std/' -e 's/truehd/dheurt/' /var/packages/VideoStation/target/lib/libsynovte.so
#重启VideoStation
sudo synopkg restart VideoStation

好了，如果你顺利执行上面的命令，那恭喜你，应该解决了。如果第二条命令执行失败，往下看。

现在说说第二条命令，这条命令是把https://raw.githubusercontent.com/Rootjhon/Synology_Enhance/main/VideoStation/DSM7_1/ffmpeg41-wrapper脚本下载到/var/packages/CodecPack/target/pack/bin/并命名为ffmpeg41。由于git被墙了，除非有梯子，要不然没办法。哈哈~~不过我已经把上面的脚本下载下来了，继续往下看怎么解决。

1、在/var/packages/CodecPack/target/pack/bin/下创建ffmpeg41，执行下面命令：

vim /var/packages/CodecPack/target/pack/bin/ffmpeg41

2、复制下面代码，粘贴上去：

#!/bin/bash

# Fork from code of BenjaminPoncet rev.12 with some revisions and little fixes.

_log(){
	echo "$(date '+%Y-%m-%d %H:%M:%S') - ${streamid} - $1" >> /tmp/ffmpeg.log

	echo "$1" | fold -w 120 | sed "s/^.*$/$(date '+%Y-%m-%d %H:%M:%S') - ${streamid} -          = &/" >> /tmp/ffmpeg.log
}

_term(){
	rm /tmp/ffmpeg-${streamid}.stderr
	_log "*** KILLCHILD ***"
	kill -TERM "$childpid" 2>/dev/null
}
