DSM 7 isn’t going t behave at all like DSM 6 when doing Plex.
Trying to ‘man-handle’ it is really difficult and usually fraught with troubles like this (They changed everything in DSM 7 – including HW access)
For Docker on Syno we have documented how to overplay a docker container on the native Plex app and be interchangeable.
The benefit here is DSM and the container work together to guarantee HW access
HW transcoding and tone mapping work flawlessly.
Here’s what is suggested. Adapt accordingly (so you don’t have to chmod all the time)
Another concern is always Subtitles. The Syno never does well with them.
Now add tone mapping and the CPU load will increase. A quad-core will be fine but a dual-core will struggle.
