Unusable TSSRT - multiple streams over one port

Hello, I’m looking for a good streaming server with a quality SRT implementation. I decided to try your open-source server. SRT itself works quite well. But there is one BIG problem. I don’t know if it’s supposed to be like this, or if it’s some bug.

The problem is that when I try to broadcast multiple SRT streams over one port, when ONE stream ends, it restarts ALL the other streams. I tried everything. Setting up through “Protocols”, creating a separate SRT push stream, separate input and output ports. But the problem is the same.

It seems the problem is mostly when one stream is closed due to inactivity.

Here is LOG where inactivity of "cam2" caused to end also "cam1"

Sometimes when I stop one stream, the second one is working, but when I try to start the first stream again, it restarts both... 

Hope this helps to solve it.

Hey there,

Thanks for the report! I can confirm I'm seeing it happen as well, and no it's not supposed to. I think we're accidentally closing the entire port instead just the streamID one. We'll have a look at it.

Hey,

Thanks for the patience, it should be fixed in the development builds together with several other tweaks!

cac86ff

Is the commit specifically

Taiwan22 commented

Hi, I've tested the development branch, and the issue seems to persist. I hope i did it right. My version shows: 3.2-4-gcac86fff Generic_64

My test setup is:
MistServer:
Protocols: HTTP, HLS, RTMP, TS over SRT
Streams: camtest and camtest1 - both just push://, buffer: 5000, Maximum live keep...:5000, Resume support: Disabled

Larix(android) camtest SRT ---> MistServer ---> OBS SRT input camtest and RTMP input camtest ---> OBS broadcast SRT camtest1 ---> MistServer ---> VLC SRT input camtest1

And when i stop OBS broadcast it shuts down both streams.

Hmm, could you do a check if there were any MistServer processes still active from the previous build? This is behaviour I'd expect from the development build before the patch.

I've tried replicating the setup, though I did use a different input for SRT than Larix (I used gstreamer), though considering the problem seems to be in MistServer closing down the connections I doubt that's going to be impactful.

I've got a gstreamer script generating a SRT feed pushing it into MistServer using Port 8889 and streamname cam1
(gstreamer -- SRT --> Mistserver (cam1) )

OBS then pulls this stream (through SRT using port 8889 and RTMP). Then pushes this to stream cam2
(MistServer -- SRT + RTMP --> OBS (mix srt+rtmp input) -- SRT --> MistServer (cam2) )

That is the same as what you're doing as far as I've understood it. The log is at the bottom.

What I'm seeing is cam1 being unaffected whether i stop the OBS push or not..

This is all cac86ff as well, the usual suspect is an older process still being active so the update hasn't happened yet.

You could also try downloading the development build from our build system and see if that works differently for you:
https://r.mistserver.org/dl/mistserver_64Vdev.tar.gz

An alternative/work around is to setup 2 SRT ports, one for incoming streams and one for outgoing. This does speed up the SRT process in general so it's not a bad method. It doesn't solve the bug you're experiencing though.

The changes would be adding another TS over SRT protocol in the protocol panel and setting this to only allow outgoing streams. Then set your original one to only incoming streams.

  • You push towards the incoming streams port
  • OBS pulls from the outgoing streams port

I've tested it again, and it seems that it is fine until I'm not watching the second stream in VLC. Then, when I stop it, it shuts down both.

I've also checked line numbers from the log, and they match the cpp file. So the build is the last development....

Alright, thanks for double-checking we'll go over it again.

Rokamun commented

Took us longer than expected, but I think we finally narrowed down the issue and solved it. What would happen is that SRT connections over the same port would share jitter settings between all streams over it. While often this would go correctly it could cause crashes if streams were exited at "the right timing".

The fix is available in:
0ec2800

We're expecting to push this as a bugfix release 3.2.2 end of this week or early next.

Hello, and thank you for all your effort.
But the problem is still the same; I don't know how you are testing it.
My simplest test setup is to broadcast from my mobile phone as cam1 to OBS, then broadcast from the same OBS as cam2, and receive cam2 in the same OBS. And every time you end one broadcast, it shuts down both.

Here are some logs.

started broadcast from larix as cam1

The only way I got it to work was by using a separate port for each input and output stream. So for two streams, I need four ports.

I think the problem is simple in that every time one broadcast ends, it closes the whole connector. "Starting connector: {"acceptable":"0","connector":"TSSRT","port":10080}"

Ah apologies, seems I have been reproducing it wrongly.

I apparently misunderstood the part where OBS would use Cam2 as an input as well. Making the proper changes did get us to reproduce it properly.

The problem being that SRT viewers can send a kill command to the process handling them, which in the case of SRT is the process also handling the inputs. We've made it so this doesn't happen. Though a Nuke command could still close down this port if the process closes too slowly (which is unlikely unless the process crashed and doesn't listen to kill commands).

The adjustments are available here: 41cf557

I don't know what to say, but it's working!!!! 👍 🥇 
Thank you so much, guys. Thank you for all your effort. I think a good thing is that you fixed a few other issues along the way, so your SRT implementation should be really good now 👍 

BTW, is there some way to support you through a donation?

Thulinma commented

This fix was included in the 3.2.2 release today 👍

Thank you for wanting to support us! It's currently a little tricky for us to accept donations - we're planning to set up a way to automatically handle these and also thank people for their donations by giving them a little bit of roadmap influence... but this is not ready yet. 😅
You can simply transfer something to us through any of these banking details, but we can't provide a receipt for that at the moment: https://mistserver.org/contact#Address
