How to set up SRT protocol for IRL streaming | sprEEEzy’s Budget IRL Backpack Guide #1

[@sprEEEzy]

Big news! I've made a dedicated tech channel: kzbin.info/door/t3O3ScWSlpGGiXLVMSNJRg - It'll feature all kinds of IRL / Streaming / Tech videos. Want to know more on IRL setups? Full playlist available here: kzbin.info/aero/PL-czD6_A6J7RXT1EKFFgBP3PJCPaBLPFL -- One thing that I missed to mention is that you might need to forward the port you're using for the SRT stream (the example "22222" port in the video). I didn't have to myself, but it depends on your router and home network setup! All info can be found here: portforward.com/, it's not hard at all :) For best results with SRT, use OBS v27: github.com/obsproject/obs-studio/releases

[@thegameshooters4188]

Please describe "forwarding the port."

[@sprEEEzy]

@@thegameshooters4188 Hey, it's the process of opening a port on your router, so the stream can access your home network (i.e. the stream PC within in). More here: portforward.com/

[@bernardrpo]

Dude, you simply saved my sanity, my work and made an entire idea come out of the paper. I'm starting a totally new streaming/broadcasting company today with your help. Soon i'll be strong and rich enough to thank you properly! This saved my life!!!!

[@sprEEEzy]

A life saved!

[@joppisaus1708]

Followed this to the letter and I am infinitely grateful. I am streaming from my phone using this method and did my first actual IRL stream today and it was amazing. Thanks again for making this guide.

[@Jayplaygame0420]

I've got it working with WiFi but 4g doesn't work, I've checked everything multiple times and there is something wrong? How do I get this working?

[@TarlochanSandhi]

I m facing same problem. Please let me know if u find solution.

[@BrandonDrummond]

Same problem here. Someone, please have the answers 😅😅

[@Perceivingmindttv]

same here :'d

[@BrandonDrummond]

​@@Perceivingmindttv I got it working! I just needed to set up port forwarding on my modem for the port the SRT was going through. It's different for every modem and internet provider so google how to port forward on "your internet provider" and it should work after that. I hope you guys work it out! It works like magic for me!

[@Perceivingmindttv]

@@BrandonDrummond can you elaborate this more? Because I've been trying to port forward 5 different ports and all alre "closed" if I check it with a port checker.

[@TerryB]

Thanks for the info. I'm currently using the LIVE U and looking for a lighter weight setup.

[@GrabaGra]

Great! Now I'm waiting for the video - how to do it with the GoPro 🔥🔥🔥

[@DTRiel.]

BROOOO !! LEGEND !!! i've literally been racking my last brain cells for, not even exaggerating, 3 or 4 hours oooooweeee

[@tail1410]

I'm a bit confused on the additional commands you applied in the URL. Those commands are from FFmpeg via the libsrt? Does that mean the TBS2603SE is using the libsrt library from FFmpeg when it is doing the encoding? So if a different encoder was used, it may not be using libsrt as its encoding library, and thus these parameters wouldn't work?

[@tomothebiker]

I tried 4G it did not work. I encoded my public PC IP Address in my phone.

[@loot6]

Yeah a lot of people seem to have this problem, including me but nobody seems to have a solution.

[@DavidFosterVlog]

Why did you download Larix screencaster and not broadcaster?

[@sprEEEzy]

It doesn't matter, they're basically the same; except the video source.

[@thomas5892]

hi!! nice vid thank you!! any changement? I try but : Can't connect server... How to find what's wrong? it's so easy but it does'nt word ;(

[@TheTruthAboutMovies]

Hello! I've got it working with WiFi but 4g doesn't work, I've checked everything multiple times and there is something wrong? How do I get this working? It just says 'cant connect to server'.

[@DadGotParks]

Same here.

[@yontimo78]

It wasn’t explained on this video but you need to make a port forward from the public ip to private ip with the chosen port under your home router’s settings

[@MitchSoda]

Cool vid, thanks for making it, however I could only get it it to work when my iPhone was on my home wifi (same network as my PC). Doesn't work on a cellular connection. Changing the IP address from your local IP to your global IP doesn't work (yes port is forwarded). I can stream to NOALBS over RTMP etc. but yeah, can't do SRT from outside my home network. Not sure why, checked your Discord for answers, and other internet searches, and couldn't find anything on this to help me figure it out. Insert my sad face, lol.

[@joppisaus1708]

I'm in the same boat. Was able to get it to work over SRT in September of 2021 but its not working now.

[@Che77o]

same here

[@Fine_art_aerial]

5:22 Don't understand how you incorporate the phone/screencaster into the mix?? How does my Netgear m1 send the signal back to my computer/obs??

[@Gökay_B]

but do you need a static ip for this?

[@TheTruthAboutMovies]

Got it working on obs with my phone but it's very glitchy! (Grey screens, assuming that's connection issues) Am I able to use my phone camera as the live streaming device if so how as the camera app itself of course has loads of overlays and all sorts of stuff in the way. Am I missing something here? Thanks.

[@stevecarty]

will this work with an M1 Mac running obs?

[@chasevegas138]

How do you go live with the GoPro?

[@Teboy]

Working if both are connected to wifi but when i used data for my phone even if i have a static no ip it says not connecting to the server. Port forwarding was set up correctly and firewall disabled

[@Pedakin]

Same issue, been killing me for hours.

[@QuixoticOdyssey]

Any tips on doing this exact same thing but with RTMP?

[@Marlow925]

Watched the 2 tutorials. Recently looked into IRL streaming and yep .. the running cost of lets say the LiveU unit is the most prohibiting cost. But I also love the idea, that this means the stream is so much more customizable.

[@timestampterrysassistant7638]

Hi I'm thinking of buying the gear, but in the comments there are a lot of people saying it isn't working with 4g. Can you make a video talking about how to get it work with 4g?

[@MoenTV]

Does GoPro support SRT? Can I send the video from GoPro to OBS with SRT instead of RTMP? Great video!

Unfortunately not. That's why I made a whole series of videos on the topic.

@@sprEEEzy thank you for your quick response! I will look into your other videos aswell.

[@thebrotherhoodlc]

I wonder what the lowest acceptable bitrate would be using HEVC + SRT for 720P streaming

[@geogmz8277]

720@30? HEVC like 2.8Mbps lower than that it's going to look like crap IMO..

[@Julya.Antoinette]

shouldnt you be using larix broadcaster instead of larix screencaster? i use screencaster and then try to use my phone camera using the camera app and cant figure out a way to remove all the camera buttons for like 30 mins. then realize i should be using broadcaster so that it would work like a camera streaming to obs

[@localkiter5945]

Thanks a lot I always look here for the SRT URL to get Larix working again through OBS, I only get it to work only on Android and not on iOS anymore. Need to refresh phones perhaps! TY alot anyways again! BTW why local ip instead of iNET ip like WAN IP or am I completely stupid since obs doesn't run on routers haha ? :P Always thought that linux was also a router or acting as one, like ipmasq ip masquerade etc. And I always get a message like a pop up that it can't connect to the server but it still works tough!

[@Resvlive]

love the SRT stuff!, still trying to get it to run on my setup

[@pawsitivepanda]

I get cannot connect to server when i try to use srt with my external ip address

[@IliaTabere]

Whatever I do, I can't open ANY port on my computer. I tried EVERYTHING. The port that I specify to open in my Firewall, Windows Defender, AntiVirus, Router ALWAYS (despite showing open in all these places) remains closed when I check it from the outside and NOTHING comes through. Is there a tutorial for THAT? How to get that freaking port open? How come yours is open by default when usually they're all closed by default?

[@icallchoco]

I am stuck at same problem. Did you found any solution?

[@BenReese]

So many technical terms used wrong in this video, but kudos for putting it out there! I'll definitely check it out again later when I'm not mowing 😂

[@sprEEEzy]

Oh yeah?

[@BenReese]

@@sprEEEzy sorry... I left you hanging lol 5:40 - "Most home IPs change every day" not really the case anymore. Your phones IP will change often and it probably won't even get its own IPv4 address, but most ISPs don't change your IP very often. Some won't even change it if you ask. My "dynamic" IP hasn't changed in years. Second, "noip" doesn't give you a static IP. It gives you a dynamic DNS. That way if/when your IP does change, the domain name will follow. Your IP is still dynamic, it's just easier to find if it changes. Also, a domain name shouldn't add a second of delay. DNS responds in milliseconds and your phone only needs to look that up if it expects the IP to change. Third, I think you missed a crucial step of port forwarding. Unless SRT can somehow work from the outside without port forwarding, viewers will need to enable this on their routers. Just noticed too you said the 1,500,000 number was in Bytes. I think that might be backwards 🤔 Each Byte is 8 Bits. Bandwidth is typically measured in Bits per second - even with video. If so, 1,500,000 Bits would be 1.43 Megabits, which seems more likely than 1.43 Megabytes (11.44 Megabits). Again, this is just feedback from what I picked up on. It's fantastic that you're making videos and this appears to be a popular topic! Keep up the great work!

[@brucecannella6439]

Great video. But instead of OBS....can vMix be used ?

[@sprEEEzy]

Think so. I can recall seeing vMix SRT somewhere.

[@bbqoutdoor9073]

Great vid!! A bit off topic, would anyone know of an livestream app that can support UVC camera as an input ideally for Iphone, but I will take Android if have to? Looking to make a simple livestream setup and later explore the SRT feature.

[@timoreck2490]

Hello, thanks for this nice video. I have a problem connecting via LTE. My cell phone shows me an unknown connection error. Could it be CG-Nat? My ISP doesn't support an IPv4 address on my current contract. So that's my current guess as to why it doesn't work.

[@sprEEEzy]

Possibly. It not easy to troubleshoot with little info. Maybe best you try the tech channels on our Discord

[@HOTLAPP]

Does AVMATRIX SE1217 H.265/264 HDMI Streaming Encoder is able to provide me the same result as the TBS 260 Se would do? If yes, via RJ45 to router streaming to KZbin, do you know the average latency? 2000ms, or the same as RTMP (6 seconds)? Thank you very much indeed

[@idanyella1]

Can I use this app and a sony action camera for IRL streaming? I want to have overlays and alerts .. so can I somehow connect my Sony action cam?

That'd be hard without a mobile encoder + router setup. You really want to use the SRT protocol.

There is something called larix grove that I couldn't quite understand.

hi sprEEEzy, thank you for all your irl tutorial videos, i've learned so much! is it possible to use camlink/hdmi capture card with our phones and stream with SRT? i've tried the larix broadcaster app but i don't think it supports it. thanks in advance!

[@sprEEEzy]

Not really. Phones typically don't have strong enough USB ports to handle a high quality inbound video from a capture card. Not to mention there isn't a good app to handle capture cards either.

Is it possible to have multiple SRT Streams into OBS at the same time? I am looking to have multiple encoders for different angles on my car, and be able to switch different scenes in obs with different SRT Streams. Would it be possible to use a AWS server, or a different port for each stream?

[@sprEEEzy]

Check out my latest video on Loopy's SRT Monitor!

[@KubaSzczygielski]

Of course it is possible. You just need to transmit other signals over different ports.

[@Resvlive]

So in OBS media source, is SRT just built in to listen? or do I have to install Nginx or some sort to setup a server?

[@sprEEEzy]

Built in! Make sure to use at least version 26

​@@sprEEEzyHey~, I was able to get my encoder to connect SRT 265. but nothing is showing in obs for some reason. Tried with larix and larix can't connect for some reason. I'm also using NOIP srt://hostname:port?=mode=caller and mode=listener (didn't add any of your appended settings to make sure I can get it running first. I opened my port for the router, but the website confirmation says its still closed? I checked netstat and i confirmed my local ip is using the 22222. I can rtmp 264 nginx just fine, not so sure what I'm missing.

[@sprEEEzy]

@@Resvlive Try calling your ISP and tell them to turn off CGNAT if it's on.

[@aaronm9353]

@@sprEEEzy There seems to be a lot of comments complaining about not being able to initiate a SRT stream over 4G and replies relating to CG-NAT. Carrier grade NAT shouldn’t be at all relevant in this scenario, unless for some reason you reverse the assigned SRT modes of the encoder and decoder pair, so that OBS is the ‘caller’ and the encoder (Larix Broadcaster etc) is the ‘listener’, which is still a perfectly valid configuration, but this would require access to the public IP address of the 4G modem, something which is not achievable for the vast majority of consumer mobile connections due to CG-NAT. The only other circumstance in which I can envisage CG-NAT being relevant is if the ‘home’ computer running OBS /vMix is itself connected to the internet via 4G broadband, in which case it is unlikely that the router’s WAN address could be reachable, again due to existing behind a NAT, in exactly the same manner as the reverse for a mobile phone over 4G. In all likelihood, everyone here posting almost identical comments about getting their stream to work on the LAN but not having success over the internet is simply not aware of the need for port forwarding to be enabled on their router or a VPN connection to be established.
