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 ca’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.

    Hi Nicolas,

    Sorry can’t help you here as I do not have a DS212+. It could be DS212+ not powerful enough or your iPad is not powerful enough? Have you tried with other devices?

    Good luck and let me know how you go.

    Well, I tried this on my DS212+, it now allows me to start the movie without any error about the audio channel, but it is first loading the movie for about 4-5 minutes (on my iPad with DS video) and then it plays it for only few minutes before loading again …
    Is my DS212+ not powerful enough ?

    Brilliant. Had been struggling with DTS support all day. For some reason ffmpeg kept saying “DTS … unspecified number of channels”. Did not find anything in google hinting into the proper direction. Input filters, ac command line option,…

    After installing, it still did not work, but for obvious reasons: The command ffmpeg used the old version still as the version number in the console showed.

    did the trick (“volume1” is shown as the install location in my case).

    Thanks very much for your help!
