I know a lot of home servers get used for plex, and I'm sure many of you have tested the hardware transcoding of PMS. When I see people talking about intel quick sync vs nvidia nvenc the topic is always revolving around the number of encodes the GPU can manage to keep up with. What I am more concerned with, yet have never really seen discussed is the quality of the encoders. What's the consensus on quick sync vs nvenc encoding? In the use case of PMS does one look noticeably better than the other? I'm still running an i7-2600 with the first generation of quick sync that supported h.264 hardware encoding. Do newer generations of the hardware encoders supported in PMS visibly look better than what I'm getting with my system?

I have a qnap nas with that cpu and i am wondering if it will be able to transcode 4k hdr movies with tonemapping down to 1080p sdr? Around 25-50mbit file rate size. If it can't, what intel iGPU can handle this? It would be for 1x stream instance. edit* Celeron J3455** -
Hello everyone. I have a weird problem with handbrake. Due the the quarantine, my university broadcasts the lessons via zoom. And I though it was a good idea to use OBS and record them for personal use, in case i want to go back and view something. But after a few weeks, the space taken by the video files started to be too much. So I though, why not transcode them to H265. Thats should help. So after a few practice runs on short videos to figure out the settings on handbrake, I was confident to get on transcoding the 50+h of uni lessons. Only one small problem. Only when selecting the H.265 (QSV) encoder, handbrake gives an error and cannot complete the transcode. Software H.265 (x265) plus hardware and software H.264 (x264 or QSV) work just fine. Also on my short practice runs, hardware H.265 worked fine. Only with the recorded uni lessons that I want to transcode it errors out. Im no expert in video formats and encoding/decoding although I study ECE so im quite familiar with how things work. I've attached one of the log files to see what kind of error it spits out. Its always the same qsv_hevc_make_header: MFXVideoENCODE_EncodeFrameAsync failed (-5) encqsvInit: qsv_hevc_make_header failed Failure to initialise thread 'Quick Sync Video encoder (Intel Media SDK)' If anyone has any idea what is causing it, I'd love to hear cause it seems to weird to work on most videos expect the one I really want to transcode. And to clarify, my PC is actually an Acer Aspire 15'' laptop (Intel Core i7-8550U / 20GB RAM / Nvidia MX150 25w). At first I though I'd use the NVENC on the MX150. And then I found out that it doesnt have the encode/decode IC... So Intel iGPU it is... Cause letting it do the software x265 transcode would be a death sentence for the laptop it self and my nerves cause I have to use it 10+h per day for uni and work. It has to be something that can be run relatively easily on the background. Thanks everyone in advance. Αριθμητική Ανάλυση Μ8 30.04.2020-1_preview.mp4 05-03-2020 22-57-58.txt -
Hi, I'm looking for some advice, I need a server/nas solution for our church's video production department. We currently have a Synology NAS with about 36TB of stotgage and we just copy files we need over standard gigabit network. and edit off local SSDs. This has been fine until now using the compressed codecs off the cameras but we have started using broadcast cameras and recording to BlackMagic SSD recorders in ProRes so moving files around and working with such large files is just not working for us. Originally we were just looking at upgrading to a more powerful synology NAS with 10Gbps ethernet but now I don't think even that is enough. We edit on Windows and I'm not sure if we should start transcoding into a different codec and maybe even use proxy files? Id like to have a system where after recording finishes we move all the SSDs into a dock or a server and it automatically copies, transcodes and archives everything ready to start editing during the week. Should we look at building an all in one server and storage solution and run 10gb back to the edit machines? Any advice on hardware, software, codecs for windows (PremiereCC) that will help up streamline our processes would be appreciated. Thanks.

Hey LTT community. I have 2 dell 980s i've gotten my hands on and have been using 1 as a plex transcoding / nzb server and the other as a pfsense firewall. Is there a possible rack mount solution to get both of these machines cleaned up and looking fancy? Possibly a 1-2U chaise i could pop these both in? Appreciate any suggestions...i just have them side by side under a desk at the moment.

I am working on a project that required transcoding bunch of h264 videos into jpeg. I did a test on my own 1050ti gpu, the testing video is 1080p at about 2.5Mbit/s. ffmpeg -i video.mp4 -c:v h264_nvenc output\%05d.jpg The result is about 90 to 100 fps. And now I need to build a server with AMD gpu (considering rx470, 480, 580) The videos would be uploaded from users, not longer then 15 seconds (450frames) I did a little searching, I think h264_amf works with amd gpu? But I dont have a amd gpu on my hand. So let me know how to enable, and how fast RX480 can be. Thanks

I'm doing research on building a NAS to support Plex streaming/transcoding, as well as simple file storage (backups). Right now I'm trying to focus in on the video transcoding for Plex, and making sure it's not going to be a big problem. On Plex Media Server's CPU recommendations page, they recommend (very roughly), a CPU with a PassMark score of at least 17000 for 4K HDR (50Mbps) transcoding to 1080p (10Mbps). I want to make sure I can support at least one stream at this quality, but I am also trying to not spend so much on a CPU. Plex Media Server also has a page up about hardware accelerated streaming, on which they state that for any OS, they support HW accelerated streaming with Intel's Quick Sync Video feature. However, they do not draw any lines between hardware accelerated streaming and CPU PassMark scores, or indicate if there is any correlation there. My expectation is that using an Intel CPU which supports Intel Quick Sync Video would lower the PassMark score required for 4K HDR transcoding, but I'm not sure by how much or what I should expect. Basically, I can spend $410 on an Intel Core i7-9700K, which has a PassMark score of 17241, but can I get away with a cheaper CPU like the Intel Core i5-9400, which also supports Intel Quick Sync Video, and still be able to transcode 4K HDR video? EDIT: It seems like the main factor in HW transcoding is the iGPU. It appears that Intel's latest is the UHD 630? In that case, I'm wondering what is the cheapest CPU I could get away with that has the UHD 630 iGPU? Or put another way, how much work needs doing that isn't HW accelerated which depends on things other than the iGPU? How important is the number of CPU threads and clock if it already has a UHD 630? EDIT2: Would an Intel G5500T perform the same with regards to HW accelerated Plex transcodes vs. an i7-9700K? EDIT3: https://pcpartpicker.com/user/krcm0209/saved/2cdNQ7 Playing around with a potential build. I am open to feedback for improvements. -
I've used makemkv to rip and it makes mkv files but I would be looking for something that rips directly to a format my my cloud home could play which is H.264. I know I could convert but looking for other options as well.

Helllooo, I want to know what the cheapest option is if I want to be able to watch my Blu-Ray Rips (MKV) outside of the home. This would require the NAS being able to transode MKV files. I was looking at the Synology DS118 which looks like it would be a cheap options to watch videos via DS Video. Are there any other recommendations one would have for a cheap NAS capable of transcoding Blu-Ray rips? P.S., not really interested in PLEX anymore as I noticed it required much more horsepower (i.e. more expensive NAS) . I am fine with manufacturer's proprietary video streaming apps, like Synology's DS Video. Any info/recommendations would help, thanks!

Hi there, apologies if if this is the wrong place to post this, but I’m having an issue with plex on a new Linux Virtual machine . its running the latest Ubuntu and plex version, I’ve chucked a load of resources at the machine, but when I try certain files that work fine through file explorer I get the error “conversion failed. The transcoded crashed or failed to load” I have tried to reinstall plex, run a cleanup and optimise, enable and disable hardware acceleration, change each of the quality settings. the one one thing I don’t really want to do is to start again... as I have a lot of media and re-indexing that will be annoying. if anyone that may have had this problem in the past and has fixed it, let us know what you did! thanks

I ripped a few Blu-rays and they struggle to play via Plex due to the high bitrate. I want to compress/transcode them via HandBrake but it says it will take about 3-5 hours depending on the video size. My CPU isn't exactly powerful (i3 8100) so I think letting it run overnight may be my only choice. Is it safe to let my PC run overnight (with automatic shutdown upon completion) for transcoding video files? I will have about 20+ Blu-ray video files I will need to transcode (probably one video file per night). Will this ruin my CPU? Any tips for transcoding? Any issues with doing this? I have adequate cooling (side panel window is taken out) so I don't think overheating will be an issue. Thanks,

My mini-ITX build which I offload (Main Rig Outputs to > Side Rig Outputs to > Twitch) my transcoding to twitch / plex is running an i5 7500 , which for the most part can do 1080 / ~30fps without issues. BUT, I have the option to upgrade to a 7700t for fairly cheap. I do want to push 1080/60 if I could, but haven't really experienced too much with how much multi-threading effects CPU Transcoding. What are your thoughts? Do you think a 7700t can achieve it? Here are some comparison links so you don't have to go to uncle google. https://versus.com/en/intel-core-i5-7500-vs-intel-core-i7-7700t http://hwbench.com/cpus/intel-core-i7-7700t-vs-intel-core-i5-7500

Okay I'm at my wit's end. How the heck can I build a computer responsible for home automation. Pre requisites, must be small, must not require more than air cooling, must be 3 1/2 inch thick - up to 24 inch height - max 14 inch wide. Touch screen, transcode minimum of 3 mpeg streams at once with power to spare. Blue ray drive. It will be running Kodi and Linux. How can I make this all work together? I know I need processing power but how can I get it small enough to be installed in a wall hidden....

Hello people of LinusTechTips, I recently built my first real personal rig (Its in my history, if a bit tweaked from that) and I picked up a Synology DC216se with 2 WD 3TB Red drives as my Network attached storage for my rig and a few laptops. After reading on synologyies website I discovered that their NAS boxes can be used to transcode video. My model only supports up tp 720p naively but I was wondering if there was a 3rd party plugin that supports 1080p Transcoding on the DC216se? As a side note, once I set up the NAS with 2 raided 3TB drives I only have collectively ~2.6 tb free on the "Drive" I know System files from DSM and other necessary files take up space so you dont actually get the full 3TB, but 400GB of files seems excessive, is this normal for RAIDed drives or synology Boxes? Thanks! -Noble

I need some kind of server at home. But i have no idea how powerful it has to be since i have never played with them before. At the moment i am using my normal computer to stream to my Raspberry Pi Plex client on my TV. This will be the main use of the server. It will be streaming high bitrate material, 1080p with DD 5.1 sound mostly. I am using direct play for most of my content but it has to be ready to transcode if necessary. On top of this i wanna use it as a cloud server, backup for my files and maybe a few uses i have not thought of yet. My main problem is MB and processor. Also the Q about ECC. I guess ECC comes down to what OS I use. Been thinking about using Freenas because Win Server is too expensive. Got any ideas or tips? Below are some ideas I have. Supermicro X10SAE Xeon E3-1231v3 Supermicro SC733T-500B 500W

So I am looking to get a NAS, probably the Synolgoy DS414, but I have a quick question about transcoding. I am probably going to use the NAS primarily as a sort of Plex server. I could set it up where plex runs on the NAS itself, but from what I gathered it would have trouble transcoding videos at 1080p. When specifically will a video need to be transcoded? If I just have a lot of .mp4 files on there streaming to my phone or a roku box or what have you, does it still need to transcode? Sorry, this is a really noobish question, but I am fairly lost. Networking is not my strong spot, so any advice is greatly appreciated. Thanks in advance.

Hi! I am in need for a NAS able to stream to a TV (LG 55LW550W) via HDMI/DLNA on a 100/100 internet. The router sits ~1m away from the TV, so range and speed isn't any problem! I found this NAS (AS202TE), however, I am unable to figure out if it can transcode and stream "heavy" videos (1080p, h264, .MKV/.MOV, namedropping), as well as stored images, to the TV . Do you have any other, better, suggestions for choice of NAS? (Synology doesn't seem to have the horsepower for streaming and transcoding). Thanks in advance, Will
