I have been working hard on a workaround for the ffmpeg issue on QNAP NAS with QTS 4.5.1 and will forward the update to QNAP.
It has an option to manually add ffmpeg to a folder in the specified database shared folder.
You’re more thanwelcome to give it a test. Feedback is really appreciated (preferably as a PM).
→ The Update is now available in the QNAP App Center.
You need to download a static build of ffmpeg manually (you can find good build for example on John Van Sickle’s page.
Make sure to download it for the correct cpu architecture. In case of Roon Server on QNAP, it should be amd64.
You can copy ffmpeg to a folder named “ffmpeg_For_RoonServer” in your database shared folder. The folder is created in the Roon Server web panel.
