SRT to OBS from Larix Broadcaster and Larix Screencaster
HTML-код
- Опубликовано: 5 авг 2024
- In this video we set up Larix Broadcaster on Android and Larix Screencaster on iPhone to push SRT streams into OBS Studio in the same local network. We then combine them into a single scene for further streaming into services like Twitch.
Twitch setup description is not included, we just show mobile and OBS setup for SRT transmission.

Merci de nous prodiguer ces explications quant à l'usage de Laryx Broadcaster. Vous êtes fantastique tout comme vos produit!
Worked for me. If anyone has issues make sure your phone is connected to your own network (not cellular) and used your own system's info and not copying exactly what he has. You may also need to set a static IP in your router for your computer so you don't have to worry about it changing. If you are using it outside your network you'll likely have to port forward and I haven't tested if that works.
thank u guys for creating this sensible tool,appreciate a lot!🐱
Nice!! I was looking for this!!
Thanks!
I did the recommended steps on my Windows PC and it worked great. But now I'm trying on my Mac on port 22222 but doesn't work. Would anyone know how to open up this port on the Mac? I've googled for commands to do this but haven't gotten anywhere on this. I've added OBS on the Firewall to accept incoming connections.
Hello. I did the netstat command and it showed that the UDP isnt same as the PID on task manager
hi , Can I use the app with an external camera like a Gopro?
Hey! I'm trying something similar but on a Mac - I'm using a Logitech Mevo camera that does SRT. I have it enabled with the URL for OBS but can't get it to work. On your PC you had to dded to port within PC on command prompt. Is there something similar to make that work on a Mac?
Should be something similar but we're not aware of that specific HW.
I did everything that you did and my phone is not showing up on OBS, it says that it stopped due to: Could not connect to server. Everything is done correctly as you showed in the video. Is there any discord server or customer support that i can get in contact with so someone can help me set it up?
You can send us a message via softvelum.com/mobile/help/
Hi, i just tested your tutorial (after failing manually configuring the stream from my android phone to my OBS on the same local network) and the results are the same.
The message in Larix Screencaster 1.0.30(35) is "srt android: Unknown connection failure".
OBS 26.0.2 on the computer is listening on the specified port as per netstat output and the windows 10 firewall is "allowed/opened" for both private and public networks and obs executable.
I also thought to try simple udp streaming to check network connectivity but larix doesnt seem to allow it.
Any idea ?
(the phone should be recent enough, its a Xiaomi Redmi 6A, Android 8.1.0, kernel 4.9.77+, both PC and phone are on the same /24 network ...)
Hi. First, try restarting OBS - it helps in some cases. Then make sure that your mobile can reach your PC. You can also try installing other SRT-capable software like vMix trial or SRTMiniServer to check if the stream goes through to your PC software. It's most probably is a connectivity issue, not Larix.
Hi there I see that in the obs source configuration for the SRT stream input the option for "RESTART PLAYBACK WHEN DEVICE BECOMES ACTIVE".. why is that ticked? is it to avoid getting out of sync with other SRT sources in obs?? OR....???
This option is used in its default value, so you should ask OBS experts about it.
thanks !
I have another question: I have 2 iphones on one appleID one will be used for kamera stream, the other one for screen streaming. Do i need 2 subscriptions or one will be enough? Thank you
Screen recording is handled by a different app - Screencaster - with a separate subscription unfortunately.
Hi, I'm having trouble with other connections on my local network when I start Larix Broadcaster Stream. My social streaming just get interrupted but only when Larix Broadcaster it's steaming, otherwise my social streaming works just fine. Is it the problem the ports I'm using? (Using ports 12000 - 13000 for Larix Broadcaster)
Not sure what you mean by "social streaming" but the problem most probably is related to ports availability in your network.
I checked OBS port like in your video. Sadly it not the same IP and also not the same PID on Taskmanager in OBS. How can i fix that?
We are not aware of OBS Sport, we run our tests on official builds. So we cannot give any specific advice. Can you give more info on that? You can also send the details to softvelum.com/mobile/help/ so our support team could help
perfect
Trying to connect Broadcaster on older iPhone 6s to OBS (ver 27.01) using SRT. Tried your methods of adding by manually and QR code but receive 'Unknown connection failure'. Also tried different ports to be sure but still nothing. Netstat shows active OBS port. iPhone is on same WiFi network. Any suggestions?
*UPDATE:* Seems it was the firewall blocking any connections to OBS.
"Allow an app to Windows Firewall" and selecting the OBS program fixed the problem. (Windows 10)
I can connect to OBS now with Larix Broadcaster!
Hello, is streaming Cap to 30fps or is it also possible to Stream in 60fps? Ty
Which app do you refer to and what is the device model? Drop us a note at softvelum.com/mobile/help/
Hi thank you for the tutorial, is there posibility to stream camera and screen capture from one device at the same time? I am asking for iOS device thanks
Unfortunately it's not implemented in our apps.
Hi there... is there a way to synchronize multiple srt streams (from Larix Android) into OBS, so that cutting between them in OBS shows NO jump in action\movement..?
Unfortunately we don't have that yet.
@@Softvelum thank you for your reply.. I hope that it is in the plan.. cheers CD
Спасибо!! все получилось с первого раза. LIKE+
Отлично!
for some reason this wouldnt work on my android phone. for the screencaster. :( I followed all the steps. Any idea? it says on the app "cant connect to server"
This means you've set the connection incorrectly. Please check the instruction and send us a ticket if you still fail.
LEGEND !
Thanks!
عالی
Hey.. i cant find if the ports are used or not in Command. i writning this netstat -aon -p UDP | findstr 49 But nothing pops up. please help
Larix and OBS will use whatever port you specify in commection.
Is there a way to do this with a GoPro? Sorry for asking if this is already answered or in another video
At the moment Larix cannot accept input streams for restreaming, this is planned for later releases.
@@Softvelum Thank you :)
I’m a little confused. Can we just choose any number for the port? ???
Yes, any port that's available on your PC for OBS can be used.
Can I use this method to stream my handy outdoors on my PC?
Sure, you should be able to do that. Just make sure you make proper network settings to allow incoming SRT connections to your OBS.
Hello! I want to use your programs for streaming.
Please advise a smartphone on which the video from the camera will be in good quality. Do I need to install a google camera on my phone, will the video quality improve from this?
Please take a look at this article: blog.wmspanel.com/2021/08/larix-broadcaster-production-best-practices.html
@@Softvelum Thanks, very interesting.
You can also answer, installing the "google camera" application on an android device can improve the quality of the video. Or is Google Pixel showing the best results because of the whole android, and not one application?
@@MegaDem0n We use Android encoder directly so there's no need to install other software.
Does this work with stream labs?
If it accepts RTMP/RTSP/SRT then definitely yes it does.
whys my ip not a standard 192 # its a short 10.0.0 type number is this why it wont connect to media source?
You should consult with network admin about it, as it's a matter of network setup.
Is there a bug preventing Larix Broadcaster from sending SRT remotely? When connected to LAN, everything works fine. When sending SRT back to OBS with mobile data, I get connection errors. I've enabled port forwarding on my router to allow connecting back to my computer's OBS. On a separate port, I'm able to forward RTMP to work fine, but would prefer to use SRT to use HEVC codec and use less kbps. Thanks!
This is definitely a network issue, not related to Larix. Notice that SRT is based on UDP so you might want to check that part in network settings as well.
@@Softvelum Yup! Did that. Also adjusted tried default latency and custom latency options. Also went with default maxbw and adjusted all the way up to 1500000. Still nothing. Is there anything else I might be missing?
@@arjayjalmaani Sorry, cannot figure that out. Usually SRT authors recommend Rendezvous mode for cases like that but we don't know if OBS supports that. If you want to try it though, please get latest build from Beta program, it has an update for rendezvous mode there.
@@Softvelum No worries. Thanks for the support!

Yeah I can't get this to work it will keep giving the error: SRT Iphone: Could not connect to server. Please check stream URL and network connection. Followed every step 3 times.
You can post a question to our helpdesk, our team might help you.
I followed all the steps explained in the video and still having some issues. I want to push an SRT feed from my Larix broadcaster app (running on iOS) into OBS Studio (running on Mac). When pushing the big red button in Larix I see the feed coming into obs, so no problem there. But when I stop and restart the srt feed no image is showing in obs. How to fix this? Some advice please.
That's probably something on OBS side, as Larix sends the stream the same way. You can also try pausing the stream instead of stopping it - that's long-tap on stop button in Larix.
@@Softvelum It may have something to do with the port number. If I change it, the feed comes in again. But that means I wil have to change the port number every time I start a video feed for livestream. Seems quite odd to me. Is there a way the check the port OBS is using on Mac? I left out that step of the video for obvious reasons. But that might just be the problem.
@@kokonutsglobalsounds6418 This should not be the case for Larix, it's a problem on OBS side. All other tools allow re-establishing connection under the same port any number of times.
Great
I have gone through every step but after importing the QR code I get this error msg: Inside stream: Can't connect to server? Can you help?
You can enter the URL manually when creating new connection. Make sure you add stream name at the end of URL as described at softvelum.com/larix/docs/
Здравствуйте! Сделал все настройки согласно видео и в никакую не работает. Larix Broadcaster сообщает об ошибке подключения к серверу. Помогите! Подскажите куда "копать"?
Вероятно, дело в сетевом окружении или мобильного девайса, или сервера. Убедитесь, что файрволы не мешают подключению.
Are you able to use 5G or LTE connection on the broadcaster app to transmit a video feed?
Yes, it works fine in our tests. If you have issues, please check app permissions to use mobile network.
@@Softvelum Hi, Thanks for the tutorial, but i'm totally lost, can you do a tuto about seting up for 4g please?
@@piscinespa907 You mean streaming from OBS to Twitch via 4G?
@@Softvelum No something like use a mobile to record (In 4g) and sending it to OBS, Not in local you know?
@@piscinespa907 You should consult with engineers who know OBS good enough to make proper netowrk setup for it.
Hi, I’ve finaly find how to stream with LB with my phone on 4g!! But on my router I must activate DMZ protocole so tins dangerous for my computer security. Is There another way without DMZ protocole ?
Sorry, we cannot give any advice on particular network setup here. You may try using Rendezvous mode for SRT though, but we never tried it with OBS.

Приветик! Хотела задать вопрос. Подключила Broadcaster к ОБС, отлично работает но задержка высокая. Можно как то убрать ее? Порт выставляла ":2020", согласно гайду другого пользователя, возможно в этом проблема?
В ОБС адрес имеет вид "srt://192.168.0.12:2020?mode=listener"
Поставьте latency в меньшее значение, например 500.
@@Softvelum спасибочки, поставила "0", помогло. Осталась небольшая задержка в виде одной секунды, или даже меньше. Совсем не получится убрать?
@@almsi Лучше оставить latency на уровне не меньше 200, так надежнее. Можете также ознакомиться с Q17 здесь, если интересно больше подробностей про задежрку и прочее softvelum.com/larix/faq/#q17
I did all like in video and it's working but i have a big latency between my camera on my phone and video in obs can i decrease latency ?
Try setting SRT "latency" parameter to lower values. If you're in the same local network it can be reduced from default 2000 to something like 500 to start. Less latency may cause packet drops so thi need to be tested in your environment.

Could not get it to work, I get "ConnName: Can't connect to server. Retrying in 3 sec." in the Larix Broadcaster app. Most things are as in the video:
- OBS active port shows in netstat, on cmd.
- The QR link didn't open to Larix Broadcaster automatically in my Pixel phone. Instead, in Larix Broadcaster app, used the option Settings > Larix Grove > Scan QR code, to scan the QR from Larix Grove website (as in 1:42) and create a new connection.
I also tried to add "&transtype=live" to the Input link in OBS, as suggested in the comments.
Notes: I'm using a Pixel 4 (Larix Broadcaster v 1.3.5 build 339) to connect to OBS (version 29.1.3) on Win 10. Both devices are connected through WiFi to the same router.
You should send this issue to our helpdesk so we could check. Thanks!
Screencaster doesn’t work as an SRT stream provider on an iPad Pro. Broadcaster works perfectly, but not Screencaster. Using same settings as broadcaster, which works perfectly, Screencaster will not connect, and when it does, only stays connected for a few seconds. We’re connecting to vMix with both apps. Any advice?
Do you try publishing simultaneously at the same IP and port of vMix?
@@Softvelum of course not...that would require different ports to work
@@TheFNNNetwork We'll need to test that properly, we'll try it a bit later. Thanks for the tip/
@@Softvelum I truly think you have a bug with an iPad and screencaster.
@@TheFNNNetwork This is a possibility, that's why we'll investigate that.
buen tutorial, tomo un poco de tiempo pero lo logre. desafortunadamente la latencia es mucha. por mas que realizo los ajustes que recomienda en los comentarios. aun asi gracias por publicar estas herramientas.
In SRT the redundancy has top priority over the latency so there will be a bit bigger delay compared to RTMP.
i can't to do this. OBS dont sees Larix. I need help
You need to check network conditions e.g. check firewall and see if your PC can tak input via designated port.
Хэй, привет, делаю всё как вашем гайде, но всё равно остаётся unknown connection error. Подскажете как бороться?
Вам нужно проверить параметры подключения - правильно ли введен адрес. Плюс проверьте, что сетевые настройки позволяют соединяться к серверу.
I am missing something? Error message says, "can't connect to server"? Can anyone help me
You should check connection URL.
I got "can't connect to server" in my larix android. Tried with 2 devices giving the same error. FTP and RTMP run fine between these devices but SRT failed.
Please check if you've set up SRT on server side correctly. It's a protocol which is different from RTMP or FTP so you need to make sure SRT is working fine there on specified interface.
@@Softvelum I don't use srt server (rtmp and ftp server run fine), just obs on listener mode, it was p2p between larix android to obs as example on video above. I've just tried to send srt stream between 2 OBS succesfully so my network is fine. I'm using latest version of larix broadcaster on my both android devices which both fail to send with the same error message "can't connect to server".
FYI, I tried also p2p from larix broadcaster to larix player (listener mode), failed with both larix broadcaster and player gave "can't connect to server". P2p between OBS to larix player also failed with OBS keep reconnecting and larix player also gave "can't connect to server". So, the one succeeded so far was only p2p between both OBS.
@@kodoxlucu This is definitely a problem with the local network setup like ports handling. We test our releases with OBS and it works properly.
@@kodoxlucu This is definitely some network issue. You can send us more details to wmspanel.com/help so we could check that as well.
can i use this whit gopro or not
Unfortunately not, GoPro requires a server to receive RTMP, Larix doesn't have it yet.
Cool, but the question is: ¿If the mobile isn't connect to the same LAN? ¿It would connect by IP Public?
It should but that needs to be tested as it highly depends on the network.
@@Softvelum ¿Is there a video connecting from IP Public?
Thanks. It would be useful a tutorial configuring OBS to be a SRT caller. Do you know if OBS can use HEVC compression alongside with SRT? Thanks!
We have no experience with that unfortunately.
@@Softvelum Larix broadcaster lets you choose h264 or hevc format. Vmix too, but I don't see the option in OBS. That's why I'm asking.
