srt VS nginx-rtmp-module

Is receiver side also using mobile internet? You could try to setup this on separate server and both sender and receiver connnect to it. https://github.com/Haivision/srt/blob/master/docs/apps/srt-live-transmit.md

Here is one example how to feed SRT stream to ffmpeg. Try streaming directly to this via OBS first and confirm it works before stacking more software between endpoints. https://github.com/Haivision/srt/issues/506

SRT, or Secure Reliable Transport, is a type of streaming protocol that provides enhanced security and reliability for video streaming. SRT is becoming increasingly popular among broadcasters and streamers including industry stalwarts such as ESPN because of its ability to deliver high-quality content over challenging network conditions and for its ability to make contribution and stream ingestion easy. SRT streams provide improved security, low latency, and flexibility and is supported by a global community of developers all contributing to the open-source project. Because of the power of SRT streams, Dolby.io Real-Time Streaming has decided to launch support with an SRT open beta program.

https://github.com/Haivision/srt/discussions/2220 I think this is probably the basis of what i did...

If it turns out to be an SRT/socket issue (rather than an audio issue) you can pump FFmpeg into https://github.com/Haivision/srt srt-live-transmit, and let that do the SRT. It is a very long time since I played with srt-live-transmit, but it did behave differently to both FFmpeg and TSDuck's SRT impementations when there were input issues. Obviously, putting more components in the chain may be disadvantageous, but component abstraction can help when debugging.

SRT is an open-source protocol developed by streaming technology provider Haivision. Known for its security, reliability, compatibility, and low-latency streaming it is the preferred protocol for members of the SRT Alliance. This protocol does not rely on a single codec, which allows developers to pair it with any audio and video codecs they desire.

I've also looked at SRT, which to all intents and purposes ought to work, but doesn't?

Regarding the first solution, I've looked through some of the source code for the NGINX RTMP Module, and I believe the code I would need to modify lives in the ngx_rtmp_cmd_module.c file: https://github.com/arut/nginx-rtmp-module/blob/master/ngx_rtmp_cmd_module.c

You could look at setting up the RTMP module on nginx and securing it with lets encrypt - https://github.com/arut/nginx-rtmp-module

foobar2000 -> OBS -> nginx server running nginx-rtmp-module

If stuck for a server I've used this in the past. nginx with an RTMP module.

Also linking a config file I commented. Unsure if it'll still work and you can definitely simplify it for OP's needs. It was a proof of concept for a streaming service I was thinking up before realising how much money I don't have, haha

If you can only output something like RTMP, then your options are a bit more limited. Set up an RTMP server somewhere (e.g. https://github.com/arut/nginx-rtmp-module), and connect with another client that will soak up the RTMP into a file - I think ffmpeg should be able to do that, but I've had the most luck with GStreamer. Again, avoid transcoding it on the way into a file, both ffmpeg and GStreamer can be set up to never touch the encoded media (just copy/pass it along).

Are you using the rtmp nginx module?

But, if it's something you want to do, and want to do it inexpensively you want to use Nginx-RTMP - http://nginx-rtmp.blogspot.com/ - this is a free version of AntMedia Server without the $70 per month fee.
