oh wow finally Plex does some decent marketing
I only opened the email to block their marketing, but then I saw Linus
Yea so good at marketing they picked a cry baby that he is not making enough money from ad revenue from UA-cam.
Yoi would think he would be more grateful from eveyone that supported him.
@@F14Mavrick Take's one to know one. Keep crying baby
@@emieldebeer awww someone got triggered by the truth. How wonderfully modern of you.
It doesn't takes one to know one when he himself went on video crying like a little girl. Get your facts straight before you cry like a communist left. 😂 😂 😂
I liked the video. He explained it where I can use the info. I've been running 2 Plex servers for 3 years now, and this short single subject video helped me. Videos allowed me to stop the and see what he was clicking on to quikly show me HOW to do it.
What's way more noticeable than less than perfect video? This message from our sponsor!
God damn, my minds been trained to expect a sponsor transition.
One big thing that was left out of the discussion here...HW transcoding is going to eat up space in your metadata folder for Plex (where the server is stored). It would be great if there's a deep dive on how to set this up properly on multiple devices (mac vs pc vs docker vs vm) with multiple different configurations.
This is a step in the right direction for Plex, but they do have some challenges ahead.
As user of plex, we neeeeeed a way to limit the selection of video qualities available to a user so they don't transcode at qualities you don't have the files for. I just don't have hard drive space for every type of file
Oh gawd, yes! Please! Listen to this man =)
I totally agree.
So I'm building a nas/media streaming device in a case that houses a mini-itx I won't be able to fit a gpu in there. How can i make this work for what I'm planning on using?
@@defyiant Regarding your question, a NAS build without room for a dedicated GPU leaves you two options: 1. CPU Transcoding - you will need A LOT of horsepower and as many cores as you can find. 2. Using a iGPU from Intel. Yes, Plex has ATi/AMD support today - but expect to experience difficulties with AMD iGPUs - haven't tested that. If you need to know more, be sure to check out Plex's knowledge base articles regarding this topic ith a quick search for "plex Using Hardware-Accelerated Streaming". Hope this helps =)
@@xpgx1 will a 12th gen cpu like the 12500 or 12600 be enough? Its 6cores 12threads im tryinh to keep the base tdp as low as possible 65w is a pretty good base line when at close to idle.
Good job Plex!!! This is how you get noticed and spread out!
And now a way to stream the video and image format subtitles separately to avoid needing the burn-in method and thereby loose the transcoding that it needs for that.
So happy to have Linus here on this channel!!
Is GPU tone mapping ever coming to Windows?
Great Collab!
Almost forgot this video isn't uploaded on Linus tech tips
After watching Plex's tutorial video, I will now try and unplug my graphics card on the run 😂😂😂
Excellent thanks
I like to use FFMPEG to batch convert my collection into one unified codec that doesn't need to be transcoded.
I would like to see a segment on settings with subtitles. I have had problems playing back anime.
I had the same issue as well. Turns out for me the srt files must be the same name as the source file. video.mp4/video.srt.
@@kibagami25 my problem has been that my Nas was transcoding and crushing the CPU, when subtitles was turned on.
@@testpilot1us Disable transcode or start video without subs and turn them on after. Worked for me.
Where are the links that were meant to be in the description?
Looks like it’s been updated now
Okay, but how do we get hardware acceleration to work on TrueNAS (FreeNAS)?
Does HA work if my Plex server is actually a WD Nas?
I can watch this video at 1.5x speed. Shame Plex doesn't have the same feature.
I've never used the built in converter. Often the best option is to have two files - one in 4k or whatever and the other in a more streamable size like 1080p or 720p
In some cases you might have to reencode the 4k video proper. My Plex server for example sometimes gets mad at 4k h265 but plays well with h264.
From what I know, transcoding is also very dependent on your client/player (the device receiving the video). If h265 always transcodes when you play videos on a certain device, might not be an issue with your server. I Direct Play h265 media all the time on the following apps:
-Plex for Windows (App not Browser)
-Plex for Mobile (With Plex Pass)
-Infuse for iOS (Allows you to watch your plex Library for free as long as they do not have TrueHD or dolby Audio)
Oh Sorry. That's assuming you do not want a quality change. If you do, then forgive me, ignore this comment.
I love plex!! ❤❤❤
Doesn't it makes more sense to cache the streams than transcoding them on demand?
Have you ever figured out how to add an external video card (GPU) to a DS1621+ for hardware transcoding?
For these synology NAS, there is no way for a gpu to be added. Unless you use an external GPU but you would have to make your own drivers. I would max out the RAM then verify the ram usage when transcoding.
@@kibagami25 That's exactly what I did, and it seems to still have issues with transcoding. Oh well, I should've bought the Intel version and had GPU built into the chip.
Doesn’t Nvidia limit transcodes to a max of 2 by default on there consumer GPUs
Can I set up a separate Plex server as a redundant fail over system? for such reasons as maintenance on the primary Plex server?
a little late to the discussion, but Plex does not support High Availability. When you shut down the server, it is shut down.
Hey Linus , Does the RTX 4090 still have limited number of Transcoding? I use my PC for gaming and Plex..
PC Spec: AMD 5900x with RAM 32GB 3600mhz, Im using the x64 version of PLEX
The GTX 1060 has a limit of 3 session (you can even see this in the Support Matrix link in the description), so did they use a custom firmware? Nvidia sets these limits because they want to sell their quadros and server cards which are mostly unrestricted but cost way more. Afaik you can have a lot more transcode sessions with newer Intel CPUs. So I would not use a dedicated graphics card for Plex transcoding. The newest Intel CPUs with P/E Cores still made some problems last time i checked, but 10* and 11* models with integrated graphics should be fine. It's also way more energy efficient.
The GTX 1060 has a limit of 3 session (you can even see this in the Support Matrix link in the description), so did they use a custom firmware?
Unlocked custom drivers can have unlimited transcoding for consumer cards.
@@joester4life Yes, that's why I asked.
How feasible is it to move the Plex server to a PC with a great graphics card and wirelessly connect to a media library on a NAS which is directly connected to the router vs running both on the NAS which has inferior transcoding abilities?
Feasible
Should definitely be feasible however probably not recommended. You would just need to mount the NAS on your PC and point plex to that mountpoint. You may find that you end up with sub-optimal performance loading files from your mounted NAS over WiFi.
@@jamesm2075 agreed, direct connection is preferred. Im currently using an nvidia shield to start off with and have all my hard drives connected to the router, works well for now. But will in future but a NUC and run Linux on it. Was thinking windows but I hear to get full hdr hardware transcode, you need to use Linux so I'll succumb lol
This is similar to my setup - I have my media on a NAS, but run the Plex server on a separate server. I have the NAS mounted as a drive on the Plex server. However, the connection is wired via ethernet, which I strongly recommend. Trusting a setup like this to Wifi is probably a mistake. However, if you're the only one using it then it probably doesn't matter too much.
Fix downloads please?
Other than that great piece of software
Now, that being said, can we get automatic optimization? Per Library...
If I set up that i want 720p optimized files, anything I put in the library that is higher than 720p should be "optimized"
So far all I could find is individual optimization
Yes. I want this feature so bad
I want that feature too with limiting the client resolutions so no one chooses a resolution that's not optimized.
I run my plex on a Windows 10 VM. The host is a windows server 2019. I have no gpu but able to transcode 5 to 7 videos on the fly. If i have around 3 people watching with direct stream, I can have more people watching. It helps that the end user changes a few settings as the default setting is not set to watch the native source resolution. Another option that could help is that if you have tons of spare RAM, you can use RAM for transcoding instead of hardware.
How do you do that? Is the ram transcoding faster with a higher ram speed?
@Linus, your highbitrate content definitely limits HW transcoding, for us regular guys though I have had over 21 Transcodes work with 32 total streams using iQSV on my i7 10700K. the CPU was barely sweating, using unRAID and the official Docker contain.
Where's the tutorial though?
Notice we didn't get to see how many streams the GPU could do, because we know the answer and I doubt Plex wants the term cracked driver used in these high profile videos.
Funny how igpu can handle more 😂
@@halfbakedbread1293 that's my main Plex server right now. 12700K ITX build with no GPU. Small, efficient and powerful.
I don't have a Hardware acceleration option available. Mine just says "transcoder quality" & "Maximum simultaneous video transcode". I have Ryzen 5600x and 1060 6Gb. Using Plex Version 4.87.2. Any help plz?
Do you have a Plex Pass? I think hardware transcoding is a paid feature.
@@PeterBrockie Hardware Trancsode is really a Plex Pass feature.
@@PeterBrockie I do not! That would explain it. Ty!
It seems like Plex has significantly lifted their game on the media front. I still think of it as a nerdy home media centre piece of software, but they're going main stream now.
Î just use Handbrake and encode every file before moving it to my NAS(Synology DS916+). this way, there is no need for transcoding and the nas can easily stream up to 20 clients while the CPU can go on vacation.
Just use handbrake and check on the first tab "web-optimized" and "metadata-passthrough". Thats the whole magic.
After you use Handbrake, what is the output that allows you to stream up to 20 clients? 720p? and what about the audio output like h264?
@@kibagami25 Most of the time the input videos are 1080p x264 encoded files. I keep the 1080p while i encode with x264 nvenc to mp4. Audio codec is aac with 160kbps.
The web optimization does the trick, cause this option allows to part time download for the file to stream instead of downloading the whole buffer size. So the streaming order priority is in the first place your internet connection speed AND your HDD speed and and then your cpu.
If you already have an MP4 that's not web-optimized, you can use ffmpeg to quickly optimize it. Takes less than a minute since all it's doing is moving some data to the beginning of the file. The command is "ffmpeg -i source.mp4 -movflags faststart -acodec copy -vcodec copy result.mp4"
@@rixatestarossa521 I use x265 these days for all my blu-ray rips. Pretty much all my hardware clients like the Apple TV natively now decode x265 in hardware and I can confirm during playback it's doing a simple Directplay. This lets me continue to rely on my ancient 2012 built AMD Plex server to stream out even 4k content since it's just spitting out compressed data to the clients (simple data transfer) and x265 lets me store most of those 4k films in only a few GBs of storage on that server so it's even less intense on that old hardware than the older/larger x264 files since it's only doing the storage and basic transmission (not decoding, hardware nor software).
So I have a Linux server with an NVidia GPU in it but plex doesn't seem to recognize it. is that supported? how can I get some help with the setup?
You can check the Plex forums, but I suspect some of the steps found on the Unraid forums would be applicable to you. I didn’t know much going in and the guide for Unraid got me transcoding with NVENC in under 15 minutes. Using Plex in Docker meant I needed to add the GPU device ID to my container settings.
Does HW acceleration works on Windows?
Yes, but you need a capable Intel processor or Nvidia gpu.
Ayy, gotta love Linus.
Not when he crys like a little baby cause he doesnt make enough money from ad revenue off of UA-cam ads
Can plex leverage AMD 660m these days?
try a quadro p2000 plz
My server runs a pair of intel Xeon X5650's , 200GB+ of ram , plex transcodes to a 60gb ram disk ..... Do I need hardware acceleration ? O.o
My server has 900000000GB RAM and uses $100 a day in electricity.
From a little UA-cam channel just over 40 times the size of Plex’s chapel 😂
I have my Plex media server setup on an old Acer Veriton I bought for 90$ 😆
Let's talk about 4K transcoding = Nope, still broken.
What about M1 and M2 chips ? Is Plex compatible
Yes!
Yeah but does m1 have hardware transcoding @@plex
When will the Let's talk DVR video be released? Still waiting for Plex to fix their paid premium service.
Had it working, do u have the proper hardware?
I don't even have a hardware acceleration checkbox.
Well somehow that sounds superficial but not pro.
At the beginning a 180GB video of Alien? What is that, 8K HDR? I'd be really interested to know what that is and where it comes from. 4K HDR UHD Remux certainly isn't.
And then no word about HDR and tone mapping?
The i5-9600k with its iGPU certainly does adequate SDR to SDR transcode but certainly not HDR to SDR with tone mapping. It doesn't even manage one stream without caching pauses...
I don't want to sound too bad but this belongs in the Beginner Week not in the Pro Week.
Wow, I had responded because I was wondering where in blazes you saw that 180 GB 8K alien video. I could not see the files that he was looking at from my iPhone screen I had to open up the video on my PC to be able to see that he was basically loading a theatre level video. I don’t know if he would be able to play that even on his beefed up machine much less transcode it down to 720…
Anyway I had included a link to a program that can download 8K videos but apparently UA-cam does not allow that kind of link. I did not even know that a person could obtain a video of that high quality.
I came in here to edit my comment and they had deleted it. Phfhphfh.
I came in here looking for some kind of help with my server but it doesn’t look like help is forthcoming unless I fork out for whatever video card Linus is Hocking…
I doubt if it would help me though because my machine is a very old Optiplex 980, Clarkdale i5. Basically rescued from a business trashcan, it used to run fairly well but now I can barely play video on my Quicken app… even with a GTX 750 TI.
@@SocialSpit might want look up the compatibility list on the 750ti. I recently learned that the 700 series cards have some pretty nasty limitations when it comes to transcoding due to age of the tech. Not sure if it applies to the 750ti but it definitely applied to the 780ti I had.
Might be worth picking up a T400 just for the generation jump. I used a decommissioned Tyan server and it works great as a media server - tossed in the T400 and it transcodes 4K to mobile without any buffering.
The only thing that caught my attention was that file size. The 4K remux I have eyes on is about 1/4 that size.
It's probably fake. The date created for the file is 9/12/2022 and the video was published 9/19/2022... It went through a round of editing so we can assume that file was made strictly for this video.
Plus, what a shitty example for transcoding because Plex cannot handle 4K transcoding well at all no matter what the bitrate is. If this file was real, it'd have to be 8k which makes it an even worse candidate for an example of transcoding.
So LTT took this sponsorship to pay for the sponsorship with MKBHD.
Coming from the guy who said using ad blockers is stealing.... This is kinda funny.
"The first thing we need to do is get PLEX PASS... before we get some media files to play."
Fixed.
yeah haha you wonder if they forgot to mention that on purpose?
Ok, something changed in the past 3 weeks, plex puts a green hue on all of my local content and fb groups nor plex has an answer. The content plays fine in vlc player. Running ubuntu 20.04 lts
Linus plex tips
More like Linus crying tips cause not enough money from UA-cam ad revenue.
Now we just need transcoding support for DV mkv files.
Sad that Plex still doesn't offer hardware transcoding with a Ryzen APU running a Linux OS... Plex ignored that thread for 4+ years now.
AMD GPU a no go?
Love Linus usually. I’ve had a Plex pass since 2013. But this is beginner coverage. I didn’t see any NVenc Vs Intel quick sync. And I only saw a cursory mention of Plex Dash for a few seconds. Is there a more in depth version of this video I Missed?
You gotta remember he is independent, and we ARE on plex's channel. He might be in the video but this is very much their show. I'd wager the fact that this video is not just lame marketing drivel is mostly to do with how much creative freedom he was allowed and just how good he is at making videos. Good on Plex for bringing in some very nice polished content and supporting independent commentators in this way. I'd love to see them commission an entire manual walkthrough from Linux but let's face it, he probably doesn't have the time..
Não quero receber mais essas mensagens, não sei inglês,ok.
Yeah marketing is great and all but when will we have support for .ass subtitles 😭
Aren't they already working?
@@GeradDepardieu777 nope, they're not supported
I see all these problems in the chat, I thought this was supposed to be a good service
still no amd transcoding too bad
Not including hardware transcode for free is why alot of people are jumping ship to emby or jelly. Also, doesn't Nvidia lock the gtx range to only 2 or 3 transcodes at a time?
Yes, but there is no such restriction in Linux, since there is a patch to the Nvidia driver. So you can get as much streams as your GPU could physically handle, but do not expect too much from your low end GTX.
@@zedalert I had heard of the patch, I believe it's available for Windows as well, but really should of mentioned in this video. Also I was under the belief that a 1050ti or 1080ti would be equal when it comes to transcoding as it's the same separate part of the core and it's no different between the same series of GPUs
@@rossharper1983 Plex under Windows still don't support hardware HDR transcoding. So the only true OS for Plex is Linux. Number of streams mainly depends on VRAM, so 1080 Ti could transcode much more streams at the same time than 1050 Ti. But to be honest even with the lowest video card you have more then enough resourses for your entire family. In my case I have Quadro P400 with only 2GB of VRAM and even it could handle up to 7 streams. Few 1080 Ti probably would be enough for a whole hotel and TVs with Plex in every room.
@@zedalert hardware HDR transcoding...do you mean HDR to SDR?
@@rossharper1983 yes.
2 mins in wow looks great, let's enable it.. Wait where's the option?? Of course, plex pass no thanks then 🙄
TOXIC HOST AND WORKPLACE!
Wait I thought he wasn't working with Plex after the ghosted him about his complaints about the softwares serious short comings.....
Simple, Dont put 4K video files on your Plex server.
Too much quality, my movies weight 5gb
This is Plex PRO week? Come on. This is "let's get beginners more interested in Plex" week. No disrespect to Linus, there's nothing wrong with this type of content, but no "Plex Pro" is learning anything from this or any of the "peo" content this far.
You guys completely give up on life?
Nice, I didn't think plex would sponsor a cry baby that he isn't making enough money from ad revenue from UA-cam. 🤦♂️ 🤦♂️ 🤦♂️ 🤦♂️
Seems that money can't by class.
Is there a way for me to disable transcoding altogether? My Plex server is running on one of these tiny i3 Lenovo ThinkCentre computers. The machine is underpowered, but I have massive upload bandwidth and I doubt I'd ever need to transcode anything when viewing on my TV or from one of my "controlled" remote locations. Can transcoding be disabled?
