Hi tim.horel,
Thanks for writing in to let us know about this issue. As @Suedkiez said Nucleus does ship with codecs installed for you. Are you having trouble playing a certain file format?
Okay - I got thrown by the setup docs that pushed me over to the ROCK installation guide. That calls for installing the codecs and the directory mentioned is empty on new Nucleus. I didn’t see anything off until the copy into the target failed. My last NUC ROCK engine failed (Ethernet port died & the substitute USB one needed FW updates that are now unavailable), so, new hardware.
It is all working properly, all formats seem to be supported.
