Hi, I’ve a PC barebones Brix gb-bxbt-2807 (Intel® Celeron N2807) 4Gb Ram 256GB ssd hdd, Windows 10, connected via a double ethernet to a Qnap TS-231 nas I use to store my multimedia contents.
I’ve installed Plex Server into the Brix and I use Apple Tv 4th as Plex Client but I can’t play my 1080p hevc film becouse the ATV wheel spins and the movie don’t start. The same happened with ipad or iphones Plex app. I’ve not problem with h.264 movies. Is an hardware or a setting problem?
If this is your CPU:

My guess would be your hardware is struggling to try and get the HEVC transcoded. You could check your Plex Media Server.log to see what it says is happening when you start the video, but I wouldn’t be surprised if it shows that it is trying to transcode with a very low speed now.
Yes it is. Your server can’t handle transcoding. The only client which can handle the direct play with HEVC format is Plex Media Player which is actually in beta and therefore only available to PlexPass users. Even then it requires a computer with some power to decode the flux.

Yes but it’s overclocked using turbo mode from Gigabyte 2.16GHz.
If I look the movie to my fullHD tv (1080p) via ATV (1080p) and it’s 1080p, the plex server need to transcode it?
Maybe I’ve not understand the difference between decoding and transcoding!

Is it a multiplatform standalone player (as VLC or Infuse) I can use directly in my ATV or Smart TV if supported or tablet and smartphones?
In that case, I don’t need Plex server!
Nah PMP is basically the replacer of PHT, and will only work on a computer mac or PC. You can do whatever you can do with PHT, as in if you are using PHT on your tv it is the same for PMP, but android has its own app as well as the smart tv have their own apps when not linked to your computer.

In this case my ATV is useless for play hevc movies 
(it’s the main reason I bought it)
my computers are not connected to the tv HDMI and the only I can use is the HTPC, so if I understand, for the moment, the only way is wait for PMP.

Don’t forget the Nvidia Shield and Roku4 which can play HEVC also.

Even with that, the recommend score for a 1080p at 10Mbps stream in H264 is 2,000. To decode HEVC and re-encode in H264 takes an even higher score. So in essence you would need to get over double the stock performance from that CPU for real-time playback of HEVC that requires transcoding. If you get a client that supports it direct play wise then almost any CPU will work for you.

This will depend on what formats the video in. If it’s 1080p in mp4/h264/aac then your ATV should have zero issues with it. (There are always a few exceptions to this). But if everything is encoded with HEVC then currently you will run into issues.
Maybe I’ve not understand the difference between decoding and transcoding!
Transcoding is the process of decoding the original video stream and encoding the video stream. So the only real difference is decoding is only half the battle.
Don’t forget the Nvidia Shield and Roku4 which can play HEVC also.
Thanks, but I spent for new ATV and now I must use the hardware I’ve.
Plex server don’t work with my htpc, VLC and Infuse too so the only solution I’ve is wait for PMP if I’m not wrong!

You could also manually convert the videos ahead of time or use the optimize feature to have the server do it. It will take a little bit longer, but once it has an optimized version that version will be able to direct play and you should not run into any issues with it.

If I use Original Quality to optimize it, can I use this version for iphone and ipad too without issues?
It’s hard to say 100% as everyone has slightly different needs. It’s easy enough to test. Just have MO convert one of your files and then try playing it back with different clients.
This way you can see first hand how this will work on your system with your clients.
I know… thread necro… but…
It has QuickSync… so surely it will have no issues transcoding???
