Guest asrequested Posted February 29, 2020 Share Posted February 29, 2020 @ .- Only some of us know that you're having some multi-dozen-core cpu which allows you to do transcoding without needing to use hw acceleration, but many readers don't. And I think for those who don't, such statements can be a bit confusing. It sounds like there was a choice while there actually isn't any as long as you don't have some monster cpu. I'm actually not a climate guy, I like overpowered devices *ahem* I've got a little something lined up... 1 Link to comment Share on other sites More sharing options...
mickle026 400 Posted February 29, 2020 Share Posted February 29, 2020 (edited) It depends on how many users you need it to cater for. I have intel i5-9400F 6 core in my server with MSI Z390Pro-A 16GB Corsair vengence 3000mhz Ram motherboard and it hardly uses anything, GPU is only an Nvidia GT760, Ive never seen it at over 40% cpu usage yet or the GPU either for that matter, no matter what its doing. What does bottleneck is the HDDs - probably because there are too many of them shared as 2 large "storage space" drives with parity, they max out at 100% when writing but are fine when reading. It is windows and the parity that slows it down, storage spaces is a good idea but the lack of info on it and options is a pain. If you ever use it create a Drive over 16TB otherwise under 16TB will use 4k clusters and kill performance, Over 16TB uses 256k clusters. However the SDDs do not, and the server and the OS are on the SSD, so not even on an m2Nvme - which they ought to be. The CPU supports HEVC 10bit decoding on chip. The CPU is actually 2x faster than the GPU (GPU uses NVDEC, Cuda fails on it). The GPU could do with a better card but there is no need yet. The server is fast and no waiting for thumbnails or pages to load. I have pcie raiser doublers in it, with sata controllers, USb expansions and LAN cards in them, also 2 Power supplies spliced together power the HDDs, as just one isn't enough. I have 3 of the 5 1gigbit LANs teamed and 2 other ip addresses I can access from the server from if its 3x1gbit is busy. So all in all its heavily loaded, but doesn't bat an eyelid ... yet Oh and if you decide to go intel just be mindfull that just because the chip fits the motherboard socket doesnt mean it will work or even power on, you have to check compatability too..

KMBanana 83 Posted February 29, 2020 Share Posted February 29, 2020 I wouldn't try to build a 4k transcoding capable server at this time, HDR transcoding isn't ready yet and transcoding down from 4k looks worse than a native 1080p file. Keep a 4k library for users who don't need to transcode and a separate 1080p copy for users who are unable to play those files IMO. Link to comment Share on other sites More sharing options...

Nonsense! 2160 to 1080 won't look worse. HDR and '4k' are not mutually exclusive! I've got a bunch of 1080 HDR stuff. Tone-mapping 10bit HDR to 8bit SDR is a challenge, but the resolution (downscaling) is very achievable. There is '4k' SDR 8bit and 10bit stuff.

[...] @ - Do you know those series episode files available from some of the big players, where 45 min full-hd has a size of like 2 GB and the 4k version has only 2.4 GB for example? In that case he would be right: The full hd version would be the better choice! Link to comment Share on other sites More sharing options...

Luke 36997 Posted February 29, 2020 Share Posted February 29, 2020 Just FYI the forum will compress any images you upload thereby making these kinds of comparisons difficult.

chef 3745 Posted February 29, 2020 Share Posted February 29, 2020 Hardware acceleration is a bit like drinking caffeine. Yeah, you may get your stuff done quicker, and damn you feel like a rockstar and unkillable....but the end result is probably not as good as you could have done. But hey, you got it done, right!?!?! @ you are hilarious! I love it! Link to comment Share on other sites More sharing options...
lightsout 144 Posted February 29, 2020 Share Posted February 29, 2020 QuickSync hardware acceleration does not consume CPU resources. Hw acceleration is provided by a separate unit/chip that is included in the CPU.. Transcoding will still require CPU resources for audio conversion or copying video data - but that's the same when using a separate GPU board. Sorry I should have said HW Acceleration instead of "GPU". Link to comment Share on other sites More sharing options...

Guest asrequested Posted March 1, 2020 Share Posted March 1, 2020 (edited) If you have a full disc rip, it might look a little better. I just used the web rip stuff. I won't waste the space on HD stuff. But the point is that downscaling from 2160 isn't worse than 1080. Edited March 1, 2020 by Doofus Link to comment Share on other sites More sharing options...

Doesn't really matter anyways HW Accel =GPU, which can mean a separate graphics card or the internal graphics of the CPU, that was what was being clarified. Exactly. The point here is that in case of Intel, the GPU is part of the CPU. So instead of Hw acceleration is provided by a separate unit/chip that is included in the CPU. I should have written Hw acceleration is provided by a separate operation unit that is part of the Intel Graphics integrated in the CPU but is working (mostly) independent of GPU processing.

Tur0k 143 Posted March 1, 2020 Share Posted March 1, 2020 (edited) I did hardware acceleration for 1080p on a 4th gen Intel for a bit (Windows) years ago. I have helped others get quicksync setup on an intel 7th gen (Windows) headless servers. I have worked other forms of hardware acceleration VAAPI for a bit (Linux and an older AMD GPU) Now, I have been running a virtualized environment (VMware esx 6.7 u3 ryzen 1700 (8 core 16 thread) 32 GB ECC memory, 1.5TB nvme memory (for vm system VHDs), 48TB disk storage (33 usable after ZFS chops it up) that is passed to a freenas VM, and Emby server is hosted on a headless Linux VM (runs on 8 threads (2 socket 4 VCPU per socket) and 8GB of RAM. At max I will have 6 clients. My nominal is 3 streams at once plus 2 live tv recording at once. CurrentlyI software transcode. Just about all the different hypervisors out there are optimized to efficiently use resources and share across guest VMs. I am working on my 4K library and when I transition I will be testing for throughout. Right now I am limited by ESXi free licensing to 8 threads per VM. I may get VMUG licensing to expand thread count per VM or look at hardware pass-through, a mid level PCIE GPU ,and driver hacking the GPU to the emby VM. Mid year this year, I am considering rebuilding my home server when the Ryzen 4000 series 8 core 16 thread #700X model drops (improvements would be pcie 4, 8+% IPC, +200Mhz clock speed, double the L2/3 Cache in comparison to the 3000 series). For me this would be moving forward 3 generations of Ryzen which is pretty substantial. I am also considering moving the xenserver or HyperV as my hypervisor instead of ESXi).
