Is there any way to test out the hardware transcoding without having a plex pass? I’d like to see how it performs on a QNAP TS-x53A with full bitrate blu ray mkv rips to an Apple TV.
Nope…
Plex Pass access only
Ok well, will it work? Because right now these rips don’t play without stuttering when Original Quality is selected in PLEX. Will the transcoding feature speed up playing in Original Quality? I know some conversion still has to be done in that case, wondering if it will benefit.
One month PP subscription is very cheap, many users have used this to test. Quality is highly dependent on a number of factors, some users are satisfied, others not… When/if Intel releases libva 2.1 and when/if Plex includes that in the transcoder we can expect improvements.

In general yes, but depends on source media codecs, NW, lan vs wan etc.
If your CPU is running around 90+%, then is is likely part of the issue.
The source files are straight blu ray rips from makemkv. Right now I’m playing Die Hard and the QNAP CPU load is sitting around 5-20% but the video is freezing constantly (audio is great).

Looks like you have a LAN bottleneck. Are you using wifi ? Or 10/100 ethernet ?

While hw transcoding for streaming works on my QNAP, it appears that it does not use hardware acceleration for the creation of optimised versions. Is there any way to check this?
Here is what Intel is doing with ATI as of now. Looks like a mix of both. Interesting times ahead.
This would make an interesting new QNAP NAS CPU. (transcode support across both GPU’s?) I guess we have to wait for them to release it and supported drivers.
I wonder if this will bleed over and allow older Intel non GPU CPU’s and ATI GPU’s to work together? Backwards compatible?
With that aside, what are the chances of supporting the Nvidia GPU for transcodes? Is that all also depending on what Intel comes up with? I will probably aim for an 8th Gen Intel or 9th gen Plex server PC and ditch Qnap server role.
But that brings up one critical question. How is the Nvidia Shield able to do the transcodes? That is I am using one of those for Server and it’s doing 4 to 5 transcodes with no problem. From what I can tell it’s an Nvidia based GPU. Is it because it’s android TV you are able to make that work? What keeps the same from happening on a Qnap with an Nvidia graphics card installed? Thanks again. Sorry if I am asking too much here too soon.
Well I bought a PLEX pass and I’m still having the same problem on the QNAP where playing in Original Quality causes the video to stutter (with clear audio) on full-bitrate blu ray mkv rips.
Did you restart the server after buying your Plex Pass? Either a restart or a ‘Sign out & back in’ will update the server’s feature set.
If so, may I see a) the XML of the file played and b) the log files , Settings - server - help - download logs, captured immediately after reproducing the problem?

I’ll look and see what’s happening with it.
Ok, here you go. I see the problem with several videos, let me know if you want me to try with another video.
Server Version 1.10.1.4602
Hardware is QNAP TS-653A
Client is Apple TV 4 (tvOS 11.2.1)
I’m sorry for being slow to reply. Thank you for pinging me.
Looking at your logs shows nothing wrong whatsoever.
I see the video can’t DirectPlay because of the audio (DTS-MA) which is 5.1 surround.
PMS pulls up the transcoder and starts sending to you.
The file is only 30 Mbps. The transcoding speed is excellent at 18.2 (it’s only converting audio).
The only thing I can deduce from the good transcode speed and lack of any warnings or errors is a network transport issue.
Is the ATV connecting up on 2.4 or 5; G, N or AC ?
If 2.4 G you’re at the functional maximum of what G (56 Mbps transport excluding TCP + Plex protocol) can do. If on marginal 5 GHz N/AC (weak signal) it will retransmit. The buffers are large. When it drops a block, it must resend the whole thing which does interrupt the playback stack. Apple should be good about this but what about the WIfi AP and wired back to the QNAP?
PS: It would be really helpful if you changed your forum name. Those underscore characters are killing my ability to ping you.

The ATV is connecting via Ethernet to a gigabit switch. The QNAP does have two NICs connected to the switch, with port trunking enabled in balance-tlb mode. This should work from what I saw here https://forums.plex.tv/discussion/175405/qnap-faq-read-me-first
I’m going to try disabling the trunking and see if anything changes.
I use port trunking but have set it up using a smart switch (HPE) and enabled full LACP behind a Virtual Switch. The key for PMS is QTS presents 1 ethernet adapter / IP address
