Celeron J3455 vs J4105) for Plex

[ander]

Hi

I owned this NAS Asustor AS-5304T ( Celeron J4105 )
Can somebody explain me difference between this CPU J4105 and older J3455 ?
Is there any benefit for Plex Server ?

Because I am not very happy with the Asustor SW and If I go for downgrade to NAS J3455, If I am missing something ?

Because actually also this device is not capable to HW transcode 4k H264 video from my DJI cam. ( this is maybe due to actual bug)
Video is buffering every 5 seconds of play, also video is blurring (sometimes, not all time) and loading is around 10 seconds for each buffer.

They have the same graphics but the the J3455 is slower.

You haven’t said what your client is so that leads me to believe you are using it for play back as well. Given the High Bitrate 4K you should be looking at something with an i3 or higher like the TVS-672xt. Reason, the J’s will fall down when it comes to HD audio.

Hi Tiebierius

I did play via TV UHD Samsung, I put already logs here

Pixelated playback when Transcoding for the first 60-90sec

Hi Wingman Here are also my logs from playing ( hw transcode )H264 4k video from my 4k DJI cam. Checked with v. 1.18.7.2318 I am playing it on UHD Samsung TV. Video is freezing and extended time loading, sometimes also blurring As mentioned also user brycegturner. (same NAS) I put also screenshots from NAS performance, I dont see there much traffic, even I heard that disk is working hard Another topic is that I tried to stream it with Windows Media DLNA via my notebook… an…

[skwor01]

As I recall the first, second and third rule of 4k was to use direct play. Also TVs typically have a 100 meg ethernet which can cuase a lot of problems streaming the 4k bitrate.

[ander]

Anyway thanks for info, so you are saying that there is no big difference, so I will maybe replace this NAS to QNAP TS-453Be with better app support.

[ander]

Yes , I was try, there is all direct setuped, but I don’t know why is transcoded.
Even via USB disk TV can play it smoothly. so no idea why is transcoded

[pl_5309]

Need to look at the Plex client settings on the TV, it said it wasn’t set for direct play.

Since you have a Plex Pass you can go to https://app.plex.tv/desktop with a browser and check the dashboard for what is being transcoded.

[ander]

Yes, I understand, on TV player is marked ON

allow direct play
allow direct stream

What more I can check ?
and why is not streamed directly ?

A.

[FordGuy61]

Look for a setting limiting bandwidth to 20 Mbps. Change it to the highest value, usually Maximum or Original.
DJI_0045 - video.bitrate limitation applies: 99940 > 20000

[ander]

Hmm, and where to change it ?
I dont see this option is Plex server settings

[ander]

Also I tried this option>
Disable video stream transcoding…

But after that on player I got this error > Not enough CPU to conversion…

[ander]

I checked Plex server settings > network …no bandwith option I found, nor in player

[Dr_Tone]

It’s in the client settings not the server.

[ander]

Checked again, there is no such network option…
in Settings is just these options: Main, Audio, Video, Manual Servers.

Checked all tabs…nothing

Here’s a pic from my LG:

[ander]

Yes, I have all set to Original, still not working.

@pl_5309

They have the same graphics

Hi Tiebierius, one more question,
according specs J4105 has Intel® UHD Graphics 600
and J3455 has Intel® HD Graphics 500

Are you sure that graphics are equal ?

A.

[MwC_Trexx]

Have you checked the NAS capabilities spreadsheet here comparing the 2 models?

[pl_5309]

The graphics cores are the same but the supporting chips are different. The J4105 picks up improvements some which aren’t used by Plex like DRM and HDMI2.0a. The VP9 10-bit Profile2 hardware decode could be depending on media.

J3455 vs J4105

Decode / Encode	Codec h264	Decode / Encode

As I already pointed out, the J3455 doesn’t have enough CPU capability for HD audio.
