Let Synology Video Station supports DTS soundtracks method
reasons: because of copyright issues, Synology Video Station does not support DTS audio tracks by default, so the default can not play a movie with DTS tracks.
Search the web for better solutions, typically by getting them to add the source http://packages.synocommunity.com, then search ffmpeg installation kit. I tried this method in the DS218 + on their own, still unable to play DTS. The last method is the use of a manual installation is resolved, should be version issues.
First enter https://github.com/SynoCommunity/spksrc/wiki/Architecture-per-Synology-model URL and look DS218 + architecture, find the "apollolake (x64) x18 Series DS218 +" this one, so know that other architectures are " apollolake ".
Https://synocommunity.com/package/ffmpeg then enter the URL, press Ctrl + F search "apollolake", find the latest version has 5.0 apollolake and 6.1 apollolake, the two are downloaded to the local hard disk.
Enter the Package Center -> Manual install -> Browse, respectively, try to choose 6.1,5.0 version is installed, try to play DTS movie soundtracks by Video Station After installing a version, if they can even get to play, you can not play on another unloading equipment version.
My own DS218 + is installed 5.0 apollolake only supports DTS audio tracks for reference purposes only.
