Transcoding on a Celeron J1900? - Zippy1970 - 2023-11-14
I've been running a Jellyfin server on a rPi 4. This works great on my own tv since it's a new tv that supports just about anything you throw at it. The problems start when I want to watch a movie on another (older) tv and transcoding is required. This makes watching movies impossible (5 seconds transcoding, 1 seconds watching). I was thinking of buying a rPi 5 but quickly decided against it since the rPi 5 still won't do hardware accelerated transcoding.
But, I can get a used Gigabyte Brix with a J1900 celeron (+4GB RAM and 120GB SSD) for about US$45. I know the J1900 has QuickSync Video, but it's a slower Celeron than for instance the N3550 so I'm not sure that will solve the transcoding problem.
Does anyone have any experience with the J1900?

i would say not even worth trying based on a recent response on another thread
i would say definitely not since getting drivers for a 10 year old cpu will be nearly impossible, devices get EOL after awhile and so do their drivers
another recommendation, when looking at specs i would highly recommend something that supports DDR4 at minimum, DDR3 is going to be a big performance drop by itself

Bay Trail has Quick Sync, but a version that Intel's current drivers no longer support. And the codec support it does have isn't great, even if Intel's drivers supported it. I think the oldest Intel currently supports is Broadwell.
For low power Intel chips, don't get anything older than Apollo Lake.

Not sure if any help...
Im running Jellyfin on an old Windows 2016 Server, with an AMD FX-8100 with 16GB DDR3 RAM & a SATA SSD for the OS.
As its a server, it doesn't have monitor, keyboard & mouse attached.
I purchased a Quadro T400 Graphics Card for it (to replace a GT710 Gfx card), and outside of HEVC\AV1 4K video's - the T400 is handling all transcoding for Jellyfin just fine.
(the Server has more than 10+yrs worth of Media stored... so some movies were originally added to the HDD back around the mid 2000's).
My consideration - while knowing i need to upgrade the CPU\MB\RAM in the Server, did i want to build a whole new server at the moment just to add Jellyfin to the Server... or should i just upgrade the Gfx card to something which could handle 'alot' (but not all) transcoding for Jellyfin.
Given i do have a very small handful of 4K 10bit HEVC video's with Dolby Surround Audio (the kind of movies which might be 30+ gig in size) i decided to just upgrade the Gfx card.
I actually use Kodi as a frontend for Jellyfin (most of the time)... so operating like this Jellyfin isn't transcoding.
Jellyfin only transcodes when i VPN back to my house (when im away) & stream thru the browser.
I may be wrong - but if you wanted to be able to hardware transcode literally every format\codec (HEVC, AV1, VP9 etc), then i was under the impression you'd want a GTX 3080 or better (4000 series) Gfx card... and i wasn't about to get one of those for my Server.
Note here - i have a RaspPi 4B in the bedroom running Kodi (with Jellyfin as its backend)... so Jellyfin essentially just metadata.
But yeah.. there's some 1080P H264 (like maybe only 2-3GB sized files) in an MKV container, which the Pi 4 struggles with while the T400 will transcode them perfectly fine.
And obviously - the Pi 4 only supports 4K @ 30Hz.
I'd suggest you build a simple server - with say minimum 8th Gen Core i3, 16GB RAM + say either GTX 1650 or Quadro T400 Gfx minimum
I believe GPU\hardware transcoding is your best bet, but unless the GPU is a model from say the last 2 years - then it wont be able to transcode everything so it then falls back to CPU for software transcoding (which is less efficient).
