RTSP to SRT

[gre2gor]

Question

I'm trying to send a local RTSP camera stream to a cloud server via SRT using MediaMTX, but I'm feeling a bit stuck and could really use some guidance.

Currently, I am able to send the stream to my SRT server using ffmpeg and runOnReady. However, I'm not sure if this is the most efficient way or if MediaMTX has a better built-in approach for this.

Here’s a rough idea of my current workflow:

My RTSP camera feeds into MediaMTX.
I use runOnReady to execute an ffmpeg command that pushes the stream to the cloud SRT server.
Is there a simpler or more efficient way to achieve this using MediaMTX? For example:

Does MediaMTX have native support for SRT output that I can leverage?
Are there any best practices or configurations I should be aware of?
Any pointers, examples, or tips would be greatly appreciated.

Thank you in advance for helping me get unstuck!

If I understand things correctly; MediaMTX is only a SRT client, you cannot publish SRT to MediaMTX.

[gre2gor]

MediaMTX is designed to receive and host streams over various protocols (RTSP, SRT, etc.), but it doesn't offer native functionality to publish or restream an incoming RTSP feed to another SRT endpoint. That’s why I'm currently using the OnReady hook to trigger an ffmpeg command, which grabs the RTSP source from MediaMTX and pushes it to my SRT server. This remains the best approach until MediaMTX adds native support for SRT output. At least that is how I understand. Correct me if that is not the case.

@gre2gor exactly, this is correct. By the way, implementing native forwarding is not that difficult but, since the feature can be easily provided by FFmpeg or GStreamer, i gave priority to other things.
