本文需要SSH操作权限，至于安全性自行评估。

本人DS218+ 6.2 update4 和 Video Station 2.4.7 测试通过，但不保证其他人也可以正常测试通过。

一、添加第三方套件库

在群晖的套件中心添加，并下载最新版ffmpeg

二、备份与修改 libsynovte.so

#backup libsynovte.so

cp /var/packages/VideoStation/target/lib/libsynovte.so /var/packages/VideoStation/target/lib/libsynovte.so.old

# remove "eac3" from blacklisted codecs in LibSynoVTE::ArgumentHelper::AbleToDecodeAudioByCodec()

sed -i 's/eac3/XXXX/' /var/packages/VideoStation/target/lib/libsynovte.so

# remove "dts" from blacklisted codecs in LibSynoVTE::ArgumentHelper::AbleToDecodeAudioByCodec()

sed -i 's/dts./XXX./' /var/packages/VideoStation/target/lib/libsynovte.so

三、备份与修改 ffmpeg

#backup ffmpeg

mv /var/packages/VideoStation/target/bin/ffmpeg /var/packages/VideoStation/target/bin/ffmpeg.old

# replace old ffmpeg binary by the one from the community package, and filter unsupported "hls_seek_time" option

cp -r /usr/local/ffmpeg/bin/ffmpeg /var/packages/VideoStation/target/bin/ffmpeg

chmod 755 /var/packages/VideoStation/target/bin/ffmpeg
