Trouble connecting to MediaMTX WHEP server with Python client

[szym1998]

Question

I'm trying to create a Python client to connect to a MediaMTX server using the WHEP (WebRTC-HTTP Egress Protocol) protocol, but I'm struggling to get started. I have a MediaMTX server running, but I'm not sure how to properly implement the client-side WHEP connection in Python.

My current setup:

• MediaMTX server running on http://10.130.7.166:8889/right/whep (the webpage with stream opens with http://10.130.7.166:8889/right)
• Python environment with aiortc and aiohttp libraries installed

I've tried implementing a basic WHEP client based on the protocol description, but I'm not sure if I'm doing it correctly.

Can someone provide guidance on:

1. The correct sequence of HTTP requests for WHEP (POST for offer, PATCH for answer)?
2. How to properly handle the SDP exchange in Python?
3. Any example code or resources for a working WHEP client in Python?

Any help or pointers in the right direction would be greatly appreciated. Thank you!

I'm trying to figure out how to do WHEP to stream audio in opus (=no flv=no rtmp). How did you create the whep stream?
(I want to catch it with ffmpeg or another existing cli tool.)
