OBS Studio 128 - How to use NDI w/ OBS for NO SCREEN TEARING dual PC Streaming - IT'S MAGIC!

[@EposVox]

▹ Elgato Stream Deck - e.lga.to/EposVoxStreamDeck

[@atradies007]

Can you use NDI from one pc directly to another pc via usb bypassing the router all together ?

[@EposVox]

No, it's specifically a network protocol. Also direct USB-USB connections between PCs never really works out for much of anything.

[@Barnacules]

You could technically use a USB NIC to USB NIC however. Also, I believe there is a way in Windows to create a network stack over USB (male to male). We used to use it at Microsoft for syncing data between boxes, however not sure if it is in the retail product.

[@iamcesarmiranda5350]

EposVox do you have an affordable Ethernet switch that you recommend? I run 350 mbps up and down!(:

[@John-np2bf]

Hello! Thanks for making these tutorials. I'm not new at all to PC's or PC gaming but I am new to streaming. These videos will help me get my stream up and running faster and easier. I do have a question though. (of course lol) I want to run a 2 PC stream. My question is this: Will my R5 2600 OC'd to 4 Ghz and 16 GB of 3k MHz RAM be adequate as my stream PC? I will be using my R7 2700, 16 GB, and 1070 for gaming.

[@ToastyBros]

OBS NDI has changed the game for our streaming setup. Love it

[@EposVox]

:D

[@CoalitionGaming]

Same for us. We recently did a 24hr stream over on Twitch using a laptop as the NDI streaming rig, and two gaming PCs each set to their own scene (and one scene that had both PC feeds on it so viewers can see both our screens), and it kicked butt for the whole 24hrs. At one point, threw my cell phone into the NDI stream as a source as I walked around the house, and that was pretty cool too. NDI rocks.

[@senthose]

2:50 really hit home, been struggling to use a capture card and roundabout ways of making them work with high refresh rate games for months and this was finally the solution that fixed it. Works fantastic thanks a ton.

[@CoalitionGaming]

Been using OBS NDI for all our streams since we did our video on it back in June. It is indeed a godsend!

[@darkghostppl]

Would you recomend it for competitive game streaming (assuming you have 2 decent pc's)? or is a capture card setup still the way to go?

[@CoalitionGaming]

id say yes, but at the same time you might notice a tiny tiny bit of FPS loss. Like, not alot honestly. Ultimately a high quality capture card is still the best route, but trying NDI wont cost you anything.

[@SeikoTheWiz]

Got to say it out loud : Love you and love Palakis. This has saved me all the trouble I had 2 years ago with RFMTP and the VLC plugin which didn't work on windows. I'M SOOOOOOOOOO HAPPY!

[@jmojica420]

Hey I used the filter for dedicated NDI output and it skyrocketed my cpu usage from about 8% to 35%. I made sure my audio was on track 1 and it used the audio across the NDI stream. Thanks for the videos man!

[@x2Twins]

Hey great video. I’m from Australia and we get nbn fibre which delivers 100mbps. Is that fast enough to be able to use NDI to deliver a good stream

[@EposVox]

NDI only goes across your home network from one end to the other, so your internet speed isn't relevant - just the networking hardware you have. But 100mbps is great for streaming overall.

[@x2Twins]

EposVox okay cool. So I’m from Australia and we have had nbn rolling out so I have that now. From the house copper cabling runs to the node nearby which then goes the the fibre optic cabling the nbn provides. Do you know if that’s good enough? If not thanks for interacting and helping me out. I dropped a sub :)

[@NorwegianCaptain]

I think it does as my pc is on 99% internet usage on my streaming pc so i can not stream becouse it is already at 99%

[@reonero958]

K

[@ExidYT]

x2??? lol

[@HotelCharliHill]

Great job making the tutorial course. I used your videos wen I first set up a year ago. Changed to a high end gaming monitor whose resolutions my capture card doesn't like and here I am again :)

[@B4NTO]

How big is the difference in performance for the Gaming PC? a benchmark would be fun to see :)

[@billygames7107]

Huge! If you are comparing streaming with gaming rig vs streaming with streaming pc (ndi) I tried it today and could barely stream from gaming rig but then did ndi and it streamed amazing and game ran atleast 75% better. That would he a cool video to watch..oh mbermind lol 1 year late

[@billygames7107]

I started using this today amd used my old laptop as a streaming pc. My gaming rig was struggling hard to play and stream and now I can play and just have obs open. I’m upgrading internet tomorrow too 400mbps so hopefully that helps. My game ran great, but my stream was a little laggy. I also switched after from 1080-720..I was greedy the first time. I bet it runs better with faster internet and lower res. NDi is magic! It saved me so much. Capture cards can go eff themselves. I love NDI!! I created a scene so I can start stream then walk over to gaming rig then change scene and boom I’m gaming then have an end scene that hides me walking across room to end stream. It’s so much fun actually and you can truly do a ton this way and your gaming pc no longer has to go ham to try and stream and game. Total life/money saver. I’m super stoked about NDI!!

[@pcomchl9356]

You’re a freaking legend. Just built a mini itx streaming pc and couldn’t even put in a capture card if I wanted to. You’re a god, thank you.

[@EposVox]

Thanks for watching!

[@Inacurate]

Care to share specs? I have an old i7-920 & HD7950 that I was hoping to setup as the streaming PC using NDI, but concerned there may not be enough horsepower. There's very little documentation in the way of comparing results based on different hardware, but I'm crawling through it looking.

[@Barnacules]

Can NDI stream individual Windows or does it have to stream the entire desktop?

[@EposVox]

If you're just using the OBS plugin, you can stream whatever you want. Whatever you set up on the OBS canvas, you can send over. Or Newtek has a streaming program to customize what you feed too. So you can do games, individual windows, webcams, whole desktop. NewTek and BirdDog sell dedicated wireless NDI broadcasters for HDMI cameras, but they're $500+ and only send like 15mbps bitrate over your network to the receiving PC.

[@banggugyangu]

NDI scan converter can grab individual windows and send them over a network with no problems.

[@Theexplorographer]

Yeah, I use NDI tools, NDI Scan Converter and NDI monitor. If you just have 1 source to send to OBS on a second machine, I just use the Scan Converter on the sending machine instead of having it run through OBS. If I want extra overlays, etc, I will use OBS for that with the NDI output plugin.

[@themightydrakonis1139]

Am I understanding correctly that you're basically still using OBS as usual to switch scenes and stuff, but instead of streaming directly from the computer that is capturing everything, it's sending everything over to the secondary PC? So I would go about running my stream as usual with all of the alerts and everything coming to the PC that I'm gaming on, but it's being streamed from the other PC?

[@JadeFarrar]

Just got on to this, clearly been missing out!

[@Pepcfreak]

Been using NDI for a bit now. Dropped it a few updates ago when the audio was garbage but now so much better. I run a 3 pc setup for streaming. PC 1 = Game play sending to pc2 via NDI then PC encodes pass 1 to PC 3 for pass two out to twitch. I am running a 2 pass encoder system. Makes for a nice look strim!

[@DonMoody]

I will have to look into this more, sounds good.

[@ExoTericGaming]

How can i connect both computer ???

[@willdoval]

does this also transfer over sound? and video?

[@EposVox]

Yes

[@jgeekw]

Will this work on StreamLabs OBS?

[@JoshuaTubeGaming]

Off Topic but the Oliver Queen and Wally West drives mad my heart happy LMAOOO

[@NanoPrime]

this process has to be followed on both pc???

[@dieterkalt4281]

diz is 2 kewl, omg thank you well, explained tutvid man, wow this is huge

[@azareltv]

this was soooo easy...just saved me buying a capture card :D

[@freerider3434]

Hey EposVox, thank you so much for providing all this knowledge! I have three very important questions, that I don't think were adressed: 1. Was this after you spoke to Psynaps about the RTMP stuff? Relevant to me because you were going to do RTMP then and discussed NDI in the end of that 2. Is it possible to record just the game source on the gaming rig, using NVENC and bitrate 200000, at the same time as outputting it to the stream rig via NDI? 3. If question 2 is a yes, is it also possible, to record the final stream footage, which would be composed on the stream rig, using NVENC and bitrate 200000 at the same time as streaming it from the stream rig? I would be forever in your debt, if you can answer these. Thanks for reading

[@poonzy7112]

is it still worth to use with a laptop/Mac

[@aakeon9149]

Thanks for the video! I was wondering if this let you capture audio from the primary pc as well

[@EposVox]

Yes, it sends the full audio mix you establish in OBS over

[@NoahWPlays]

The quality being put to Twitch after using this method, is complete garbage. It is set to downscale to 720p and it is at 60fps but the quality is so bad. Have I done something wrong?

[@pompo7744]

Wait so do both the pc’s need to be connected to each other or they just both need to be connected to the router with Ethernet cables?

[@EposVox]

To the router is fine

[@pompo7744]

Thanks bro

[@AbstractDesigns]

Does NDI takes more ressources to encode than just like running a stream on a solo pc ?

[@mrgusse]

I was checking if you had a tutorial on the advanced scene switcher, but I noticed the only thing you have covered (that I can find) is the part depending on what monitor you're on. Could you do one for the whole package? Would be really appreciated.

[@Thomassolbakk2000]

After the steps to 6:29 my screen is completly black. What can i do??

[@taylorIndependenceHall]

idk i cant get the image to come up on the streaming second pc i can get the ndi source on my gaming pc to bring up the picture of the gaming pc

[@MadgametrixGlogs]

Run it on your internal graphics card...worked for me

[@xformi]

Gotte be aware of NDI using AVX a lot, resulting in more power usage of the sources processor and with such more heat. Another issue (although this is the same when using an additional local OBS-instance for previewing to a capture card to work around tearing) are lagged frames, so one gotta make sure the source-pc doesnt run at 100% cpu/gpu usage. Besides this it is amazing and i love not having to use a capture card anymore - no more awkward audio setups!!!

[@COSMINELSEN]

Ok nice tutorial My questions 1.On what pc u set the scenes like subscribers/donations etc? Gaming or Stream pc? 2.On what pc do u set the audio sound and microfone connected? 3. Is a probblem if i dont have a GPU on stream pc? 4.can i stream with 240hz gaming pc for the stream pc that have 144hz? My rig is Gaming Pc : i9 7920x with 1080ti 240hz Stream pc : only i7 7700k NO GPU 144hz

[@CoalitionGaming]

On my setup, I set everything up on my gaming PC as if I were going to stream from a single system. Then I just capture that on the 2nd PC with OBS NDI. So that way I have full control of the stream from the main computer.

[@GR412]

Also, this may sound like an obvious question, but are the scenes and sources in OBS located and controlled on the streaming PC or on the gaming PC? I'm not entirely sure.

[@EposVox]

You're sending a signal from one OBS to the other. Whatever is set up in the scene on your gaming PC shows up in the source on your second PC as if it's a webcam or something. You can add more overlays or whatever from there. So the answer is "both." But you wanna do most of the extra overlays and mixing and such on your streaming PC to reduce performance impact on gaming PC.

[@GR412]

I see, thanks for the information.

[@trb-mrbandookyt2157]

do i need to install OBS in second pc as well?

[@KeineAhnungWasFürEinName]

Better than elgato hd 60 pro?

[@batmanonweekends]

Just curious!! All audio sources, lights, stream deck, etc should be plugged into the gaming pc or the streaming pc? Does it matter?

[@Pabula]

Thanks for the video, hope you can do a future video into cpu usage extra on the gaming pc and streaming pc to see how much you really take on each.

[@EposVox]

I showed it here, there was only a max of like 5% extra added. Not much other ways for me to quantify it.

[@Pabula]

THanks for the reply Epos, for running a dual streaming setup (game and streaming), both need OBS right? one to create the NDI source and the other PC also needs OBS to do the streaming/recording, and both need the NDI plugning?

[@EposVox]

Correct! And the NDI runtime.

[@Pabula]

Thanks for the confirmation, Can OBS on the gaming computer using the NDI plugin transmit a partial area of screen to the streaming PC? for example an Nvidia surround 7680x1440 (3x 2560x1440) to mark an area inside the nvidia surround to be transmitted to the recording/streaming pc?

[@EposVox]

It transmits whatever you send through OBS on the first PC, and even then you can still crop/adjust from there. You can do whatever you want

[@Inacurate]

Good video, but a lot of questions I see people having even now six months later in regards to what kind of hardware is sufficient to run this setup. It seems CPU is more important than a GPU, but not a lot of discussion on that. Any suggestions for more in depth reading with a focus on what kind of hardware will result in decent 720p@60, at a minimum?

[@SimGamerNerd]

Thank you very much

[@colthenry1594]

Yeah, I'm not for sure if this video is just now out dated or what. But there is far more to setting it up now then the video alludes too. I'm still in the process of troubleshooting why I cannot view the NDI source on the capture PC, but I'm about on hour 4 of reading and watching youtube videos and experimenting. Might be time for a follow up?

[@EposVox]

The main process is the same - install OBS plugin with redistributable on both machines, reboot, start ndi output on 1 pc, add ndi source on the other. That has not changed. If getting a black screen you may have to add OBS as an exception to windows firewall

[@S3rv3nT4p]

wait do you HAVE to use 2 PCs in order to use the NDI plugin?

[@robbyjamess]

Yes thats the only purpose for NDI if you're only using one pc then you dont need it

[@S3rv3nT4p]

Damn! So is there a way to get my own and someone else face cam on the screen for a collaborating video for KZbin?

@@S3rv3nT4p the other person would have to install NDI and have his webcam as his video source. then you add that as your ndi source

[@RUMBLERIDER2]

Nice video, well explained. Question please. I have a Avermedia 4k, and it records fine to OBS. I also use Discord for chat, but I pick up my friends voices on recordings, how can I mute them, as they are not keen on being recorded.

[@EstrellaMFGZ]

ok so im watching this a year later. The NDI options have changed. i assume that i am supposed to set my gaming Pc to NDI preview output and my stream pc to main output would i be right in assuming this?

[@EposVox]

Nope. Both of those are output options, just different quality levels. Gaming PC Main output, then add it as a source as shown in the video

[@EstrellaMFGZ]

@@EposVox and on the stream pc i dont have to select anything?

[@tdtsportstalk270]

Oh my flipping god! I'm getting so flipping frustrated!!! My damn OBS will not allow me to display a window! This is at least the 15th thing I have tried to get it to work with no success. I downloaded the NDI, I chose NDI source, selected the window, and nothing comes up. I uninstalled it at least 5 times now and its still not working. Also, the browse, the window capture and the game capture are all not working. The only thing working is the display source for the entire screen, as well as my webcam. I've looked at multiple obs videos trying to troubleshoot and nothing as worked. Just throwing this out with hope someone can help. I don't know what to do.

[@finger00]

On the gaming PC in OBS at the top of the window select tools> NDI output settings> check main display. On streaming PC add new source select NDI source and you should see options. If you still have no options be sure media sharing is on in win 10 for both PC's.

[@ItsPabloDiscobar]

I'm still quite confused as to what I should set my scale output on my gaming pc and what it would mean for the base and scaled resolution settings on the streaming pc. And is it the best to scale in the video tab on my gaming pc or leave it all unscaled and scale it on my streaming pc? Or in which tab schould I scale (Video or Output) and on which pc (Gaming or Streaming)? I don't really seem to find an answer about that, or maybe it's common knowledge but sadly not for me :p Looking forward to your answer if you would have the time :) Anyways nice videos!

[@EposVox]

The NDI send is only affected by the Video tab in settings on the gaming PC. Output settings on that PC do not affect anything

[@ItsPabloDiscobar]

Wow thanks for the reply! Really appreciate your time. And when I scale on the gaming pc in the video tab I guess that I have to set the basic canvas on the streaming pc equal to the scaled setting on gaming pc right? Or do you think that's it's better to send out 1080p and then scale it via the video tab or the output tab on the streaming pc? These are my last settings I've been stuck at :p Thanks again tho!

[@EposVox]

If you're scaling anyway it's more cost-effective to do it on the gaming PC first and then match settings on Streaming PC. But it's not a huge difference either way TBH, and doing it on Streaming PC gives you more flexibility

[@ItsPabloDiscobar]

Thank you so much, now I'm completely sure because you gave me the information I needed, amazing!

[@EposVox]

Glad to help!

[@CovildoAg0nY]

Well, now a question... I Have only a 10/100 router, and NDI just murder my network bandwitch, but I have config 2 separate network cards, and link the pc's with a crossover cable, its a diferent IP, how can I configure NDI to send data through that secundary IP? and not through my normal internet network?

[@HypNoTiXz]

NDI works best with Gigabit connection, Cat6+ cables recommended.

[@turretRAID646]

Thank you.

[@astijuskarvauskas5175]

Just checking, you can use this plugin to record aswell right?

[@legitxswagzz]

So do you need to install NDI on both computers and run them at the same time?

[@kurocxl5497]

would I just have to use ethernet on my stream pc or on both?

[@EposVox]

both.

[@motoburn]

so i connect another pc with a Ethernet Cable and use ndi with obs?

[@theapartmentstudio9648]

How does the NDI on the Capture Rig know what specific source you are trying to get?

[@EposVox]

From the Tools menu, it sends the normal stream output you see. If it's used via the filter, it's whatever source you put it on.

[@TheWrs2609]

can u do this just for 1 pc set up

[@EposVox]

There would be no point. That's what normal software capture is for

[@AdiDoraiburu]

My second PC is not detecting the NDI from the first PC

[@DarkViperAU]

Hey. I have had issues with desync whenever I alt-tab using NDI. Any tips?

[@danielclever5626]

Hi, does NDI always need to be used with an internet connected router or can you set it up to be used anywhere without the need of internet? I ask this because i would like to mainly use NDI for live graphics but i have professional equipment for the livestreaming. Thanks

[@EposVox]

It does not need internet.

[@nordicbattalion3394]

Been using NDI scan converter for a bit now and it's magic for streaming! However, i'm trying it out as recording now, but i get mixed results as far as quality goes. I'm setting up the replay buffer in OBS to a minute with lossless quality, new Nvenc and maximum memory allocation allowed (8GB). When you record gameplay, do you use Full 709 color in advanced settings or partial? Is NDI downgrading quality a lot?

[@HearthsTavern]

I was about to buy an elgato usb capture card.. I've literally saved by turning my old alienware with an i7 6700hq and a 970m.. into a beautiful streaming rig. I was on the fence of building one or just turning my laptop into a stream machine. THE NDI feature. Is amazing.. CRISP BEAUTIFUL STREAM!!

[@EposVox]

:D awesome

[@brandflakes1]

How did you set up the two PCs to get NDI working smoothly? What's your situation with the Ethernet cables?

[@HearthsTavern]

Brandflakes I just set it up per the norm like his video but I used network sync instead of internal for the audio. It’s running at 140mb through my network from what I’ve noticed. My isp is 1gb down 200 up. But it’s worked on 50/10 isp as well. It’s super smooth I use quicksync as the encoder on gaming pc and use nvenc on stream rig Gaming rig uses 1080 with i7 7700 but enabled intel gpu to use quicksync option. I stream nvenc on my 970m on my 2015 Alienware laptop

[@HearthsTavern]

Brandflakes I am using cat6 cables on my router as wel

[@jatorr]

Question, is this viable for those of us who record 1400p videos for editing later, or should we invest in a capture card like the 4k60? Upgrading my gaming PC and I don't really want to upgrade my other PC in order to use the 4k60, since my current (will be the streaming/recording PC) PC is 4th gen i7 4790k and that is not capable of running 4k60 according to Elgato.

[@CzeryGamer]

i dont know why but i have desync audio vs video with NDI

[@IeuanAlli]

EposVox. I have a few questions. I don't have a second pc yet and capture card means no 144hz however i would like to know if any audio passes over as well? If it does, then my voicemeeter with 3 tracks could go bust and if it doesn't then i VBAN. So does audio go through and no mobo have 2 Ethernet so is a USB Ethernet adapter good to use? Also can i use this on Streamlabs' OBS too? Thanks

[@EposVox]

1 - the audio mixed in OBS is sent over as 1 track as if it was being sent to a stream. So stuff needs balanced in the gaming rig or your mic/etc. hooked up to your encoding rig and balanced there. 2 - You don't need 2 ethernet ports, your computers both need to be plugged into a router or switch, not to each other. 3 - no, SLOBS doesn't have any plugin support at all rn

[@MFMArt]

Im curious, because the NDI is still using a video output from the gaming pc, what kind of performance loss are we seeing through that? I know its not the same as the encoding is happening else where, but screen cap still has its issues

[@ImCrewy]

Ok I've had an issue and i'm at my wits end. My audio is delayed and yes i've made separate NDI outputs for my audio channels with no luck and inconsistent delay. Sometimes the main NDI output including audio and video is fine, sometimes its unpredictably out of sync. I really don't want to have to fork out the $250 AUD for a HD60PRO but it's looking like I have to because I can't fix this at all. I feel like because I use a camlink the amount of data is too large for NDI to properly cope but that surely can't be it. any help is greatly appreciated.

[@gelucci86]

Do you noticed any microstutter on second pc? I have 2 midrange gaming PCs but always have some light stuttering when using NDI. Even when not plaing but just watching any video. Have gigabit network. Network usage during NDI about 20mb/sec.

[@FuuwahVT]

can I use usb to ethernet for a second usb port on my streaming pc?

[@treycutz577]

can i do it with a mac and a windows?

[@BARTISHERE]

Did you ever try 4k and 60fps? It seems NDI is having massive trouble with transmitting that.

[@EposVox]

You'll need faster than normal gigabit networking for that.

[@timsmoderngear]

While this video is already a bit old, I would like to know WHAT exactly is transmitted via NDI? Does my OBS configuration matter on my gaming rig or is OBS just mirroring the preview-window to the streaming rig? Are there some kind of optimization options to improve the FPS between PC1 and PC2?

[@EposVox]

Your output settings tab has no effect. Only the resolution/framerate from the video tab. The final mix - as if it's being sent to your streaming destination - is sent via NDI. Only optimizations really are to reduce network congestion or run a dedicated LAN line between the two PCs and send NDI over that. Or to send a lower resolution from PC 1.

[@jhonatanramiro]

Hello! It is possuble to record the screen on the 2nd PC?

[@pregametv100]

whats causing the audio echoing on my streaming pc? I am using a 2x PC setup. Now I have played with advanced audio properties and have desktop audio set to Monitor only and NDI plugin source set to monitor and output. On my gaming PC I only have Desktop audio and Mic going out. So Im kinda lost. any help would be appreciated. thanks for all your videos as well.

[@pregametv100]

I fixed it. I found your other video on echoing.. Thank you.

[@MajorKrafter]

Does NDI capture the Audio too?

[@EposVox]

yes

[@808Mark]

@eposvox what you share in this video works great for me streaming with two PC's but can you tell me how I can eliminate the echo from stream lab alerts? I have my corsair void headset/mic on my streaming PC and in order to hear the gaming PC I need the advanced audio option for monitor and output on for ndi.. in the stream or recording there is no echo with alerts but in my ears I hear the alert twice...

[@thomasnunn6343]

Have a good gaming system, but for the stream PC (receiving the NDI) what kind of specs does it need? Does it need a lot of cores? Just want to see what type of budget system I can use as the stream PC without overspending. If it doesn’t require a lot, I don’t want to spend a lot for 1080@60 FPS streaming.

[@EposVox]

Streaming is more intensive than gaming, so you'll need something powerful. You could just get like a 1050ti GPU and do hardware encoding, but if you want X264 you want at least a quad-core i5 or Ryzen equivalent w/ hyperthreading.

[@thomasnunn6343]

EposVox thanks; just wasn’t sure if I absolutely needed a Ryzen 1700, or if I could get the same results with a quad core i5 or i7 to ensure 1080@60 with ndi

[@EposVox]

Yeah you can go a lower tier or so

[@CoalitionGaming]

I use a Xeon E5-1620 (sandy bridge hyperthreading quad-core, 3.6ghz base/3.9ghz turbo) as the CPU in my second PC for NDI streaming and it works great. You could even possibly get away with a quad or hex core from 1st gen core i-series era if you can find a cheap enough setup. Say..an HP Z400 with a Xeon quad or hex core for anywhere from $150-$300 depending on config, from ebay. I stream 720p60 at 5500kbps, but 1080p30 would also easily be doable. Even have the CPU preset in OBS cranked up to Medium. A hyperthreading dual core can do 720p30fps as an NDI rig from past experience too.

[@evilencho7456]

Hey, great video man! But, I do have a problem, when I'm streaming using NDI, I get high ping playing online, both PC's have a wired connection to my router. So when is sending the data to the other PC I see that it uses 70 to 100mb. I have 100/100. Is there a way to fix this without setting the lowest bandwidth? Like setting an specific amount of speed to use?

[@EposVox]

"100/100" as in your router is only 100mbit capable locally? Virtually any router made in the last 20 years should be running gigabit. Your internet speed is irrelevant to your local network transfer speed

[@evilencho7456]

@@EposVox I think I know what the problem is, all my wired connections are using a CAT6 or CAT6 cable instead of gigabit, could that be the problem?

Yep! Made a big video essay about what NDI is all about last month: kzbin.info/www/bejne/fqCbqWesf72ArZI And I have a video interview coming next week w/ NDI's creator!

[@MrNightfate]

so the Ethernet is going to router ? or is going Pc to Pc, my 2 pc have 1 ethernet

[@EposVox]

As long as both are wired to a router or switch that's all you need.

[@nokkenmg]

has anyone one else had a problem where the audio sound like you are in an empty room? like it sounds almost hollowish?? if so how did you fix it??

[@Playdohpig]

When I click add on the second pc NDI source doesn’t show up as an option.

[@aspectmalign]

Is this the same on streamlabs obs

[@TheWrs2609]

Can this be used in Streamlabs obs

[@EposVox]

Yes

[@msinfo32]

Can I use a raspberry pi for this?

[@EposVox]

No

[@msinfo32]

@@EposVox u said about Linux. I know another way any way

[@EposVox]

It being able to run on Linux and it running on a Raspberry Pi are two very different things.

[@Lordblanca]

Do you have a course on NDI and linux. Streaming from Windows to linux Ubuntu thanks

[@AdamTheFisherman]

I seem to get audio dysnc sometimes, what to do? Also whats the filter for Dedicated NDI output (Audio only) - Would that fix the audio problem?

[@404rocky4]

Do you have to use the same network for both of the computers? I have my gaming pc and then i have a laptop i'd like to stream on. I was thinking if i can use phones network on the streaming pc and WIFI on gaming, does that work?

[@jaizon]

A question though: If I set up to stream in 720p how low can I go on the second PC?

[@TheNielsAlmelo]

will it impact the system from the ndi output or is the impact as small as it would be with a capture card?

[@EposVox]

It can't be as small as a capture card to a second rig, but it's way way way smaller impact than encoding on the single machine

[@TheNielsAlmelo]

thank you for your quick response! I also heard people saying that cat5 is to slow, and you needed cat 5e/6. if so, do you know if its just fine to have the faster cables run to a switch, and have the switch connected with the modem with a normal cat 5 cable?

[@EposVox]

For most uses, unless your cat5 runs are super short, it will be too slow. Generally maxes out at 100mbps and even for 1080p60, NDI can use 200+mbps throughput.

[@TheNielsAlmelo]

oh okay, so would you recommend a cat6 from my switch to my router? or would cat6 from the computers to the switch work just fine?

[@EposVox]

All you need is from computers to the switch. Just need NDI throughput between each PC, not to the internet

[@HotelCharliHill]

Hmmm.. I bought an old USB 2.0 Bridge cable today to connect my gaming PC to the streaming PC so I could transfer the data (rather than it go over the modem which I figure should be dedicated to the internet action and uploading the stream - or would my modem handle the 100mb/s video/audio being sent between pc's without causing issues on the internet modem???), is this workable? I've been looking at this for a few hours now because the old cable's driver's don't work with win 10

[@funguy550]

Hi, Can you share pc spec for streaming?

[@derekP423]

so does both pc need ndi downloaded

[@EposVox]

Yes

[@verse4k755]

So does ndi capture all the audio sources on your gaming pc and sends it over to your stream pc I’m very new to this and bouta build my streaming pc i could always buy an elgato and sending the feed over for gameplay is something I understand but when it comes to the capturing of game discord and mic audio I get very confused @eposVox

[@mrpac6756]

i have installed NDi on both pc. But when im on the gaming pc and choose the output it dosent start cause i can go in to settings and change id i whant to. whats wrong?

[@joshrau6037]

Potentially a dumb question but, if the NDI plugin uses your network, does it get sent somewhere and back or does it stay on the network? Aka does it have a heavy impact on network speed ?

[@Travis2L]

No. It’s on your LOCAL network. No internet usage. Only internet used is when your streaming pc is broadcasting to your destination and the bandwidth it requires to play the game.
