[SOLVED] Plex, h265, and the Synology DS1019+

[mpalermo73]

I also have the Synology DS1019+ and am running Plex 1.19.2.2737 currently. It seems to transcode h264 just fine, but when trying to transcode a h265 file, Plex says

This server is not powerful enough to convert video.

despite the DS1019+ having a hardware decoder for both h264 and h265:

H.264 (AVC), H.265 (HEVC), MPEG-2 and VC-1; maximum resolution: 4K (4096 x 2160); maximum frame rate per second (FPS): 30

Synology Inc.

The test file:

You’re right… the CPU built into your NAS should be able to handle h265 input.
So first things first: do you have HW accelerated transcoding enabled in your Plex Media Server settings?
Depending on the file itself, the CPU might indeed not be strong enough to transcode the video solely by software power only (PassMark is below 2500; encoding a file with that bitrate/size in h264 will already take a PassMark score of 2000… with a h265 source you also need to consider decoding that)

Settings > [Server Name] > Transcoder > Use hardware-accelerated video encoding

OMG I can’t believe I forgot to type that part… :-\ Yes I do have hardware acceleration enabled.

You have checked dissable video stream transcoding. You will have to uncheck that.

Thank you.

I’m really not this dense. I’m really not. You gotta believe me…
