Enable Synology DTS transcoding with ffmpeg

Synology does NOT support DTS on its products due to licensing problems if I’m not mistaken. But there is a workaround for this. What we need to do is install a 3rd party ffmpeg package and that’s all 🙂

Install ffmpeg package to your Synology NAS

1. Go to the Package Center and click on Settings.

Synology_DTS_codec_12. Click on ‘Package Sources’.

Synology_DTS_codec_23. Click ‘Add’ and enter the following details.

Synology_DTS_codec_3Name: SynoCommunity


4. Click ‘OK’ to save your changes. Then click on ‘General’ tab and select ‘Any publisher’ in the Trust Level section.


5. From the Package Center, select Community tab on the left hand side and look for ffmpeg (If you can’t see the package you might need to hit the ‘Refresh’ button). Install ffmpeg by clicking on ‘Install’ button.


6. Click on ffmpeg and check if it’s running. If not, click on ‘Action’ and select ‘Run’.


That’s it! It should all be working now! Your Synology NAS now support media with DTS codec!

This is tested on DS216play running DSM 6.0.2-8451 Update 7. Please let me know on the comments section below if it work for other Synology NAS models.
