Plex Media Server Hardware Transcoding on Synology DS216+II

It was related to Plex Pass. I just purchased a monthly subscription and now it’s there :smiley:

Ok. That’s good to know. Is the HW transcoding working ?

Yeah, it looks like it, although most of my media plays directly on my iPhone and only transcodes audio. I need to test it on my ChromeCast later, which was the main reason for me wanting to have HW transcoding support.

I tried it on my NAS, but so far the results are not the best.
I’ve tested with a few x264 movies on my Android phone.
If i dont use hardware transcode, cpu load is 95-99% but playback is smooth.
If i use hardware transcode, cpu load is 20-45% but i get a 1 second pause/freeze every 15 seconds or so.
Is that something you guys have heard of before?

I only have the same issue with some x265 titles. x264 runs smoothly. I have set the settings on the plex client on my Android phone on play “original quality”.

Yes (it says there is a newer version available next to that). I also tried running just the Docker method using various versions (deb i386 images) but again the transcoder menu doesn’t show that option…

The transcoder option requires a Plex Pass. I have adjusted the instruction in my first post.

Hi,
Tried to install on my DS214Play (not sure if it has the right CPU) but i got an installation error, see included screenshot. I’m running DSM 6.1.3-15152 Update 1.

It requires the 64-bit Intel version of DSM. The processor of the DS214Play (Intel Atom CE5335) should be able to run it, but I don’t know if Synology released a 64-bit version of DSM for the DS214Play.

Ah,

Ok, well, I’m was on the fence of getting a new one anyway so maybe this was the gentle push I needed.

Thanks for the help and see you on the other side of the fence. :slight_smile:

I tried this on my DS916+ and my experience was similar to @jantlinneberg

When transcoding a 1080p mkv for playback on my AppleTV, the CPU went down to around 20% (from 80%-97% without HW transcode enabled), however, the playback was choppy and I would regularly see the dreaded “Your server is not powerful enough” message

My experience improved by turning off the subtitles. What was your experience running transcoding at 720p ?

Same here, DS916+. Hardly any cpu usage with HW transcode enabled, but same as @Objectivecat and @jantlinneberg .
It’s almost as if the upload of the video is limited speed wise, but seeing as I have fibre with 500mb that shouldn’t be the case.

Does the new preview 4 (released today) require the same steps in ssh console?
Or will it work “right out of the box”?

Not sure. Just give it a shot.

@erik_de_bont, you mention you turned off the subs, but that should be one of the main selling points right? right now all my titles need to be transcoded, as I use subs every where.

In my case with subs on, it indeed is also still at 99% CPU usage…

after 1 min I got a crash, and now I get this every time:

rebooted and the playback error disappeared. still CPU @ 99% (also after following the directions posted here…)

Try the new preview 4 build 1.8.1.(see first post) It’s a lot better than the previous one.

that’s the one I tried :wink: had the 1.60 version on the system before, now have the 1.8 installed. Same result.

Strange…it looks like the transcoding isn’t working at all on your NAS. Are you able uninstall plex and start the configuration/installation from scratch ?

Can you explain what the startup script is doing and exactly how to create it? I have the SSH working, but I’m not sure how to create the script from scratch. I’m a newb with SSH.
