Media Streaming Servers for Django

Question

I and my team are starting a project where in we are building a scalable live streaming platform just like Youtube. We are using Django as the backend framework. Which is the best media streaming library/server that can be used to achieve the result(It should work along the django project)?

Previous Attempts : We researched about various media streaming servers and shortlisted the following three(based on our requirements that it should be able to scale up to a commercial level):

1. Ngnix RTMP module https://github.com/arut/nginx-rtmp-module/
2. Node Media Server https://github.com/illuspas/Node-Media-Server
3. django channels + Janus webrtc https://janus.conf.meetecho.com/

We are struggling to decide which one to use for our project. I have seen a lot of people use django channels + Janus webrtc with django to deal with such projects. But one of my teammates had a bad experience with django channels while working on a similar project hence he is advising us not to go with it. Ngnix module is attractive and a really good reputation on github but I didn't understand it well. We are very doubtful of Node Media server, no positive reviews nor negative reviews. Can you please suggest a better option maybe among them or a different one? Thank you! Any suggestions are welcome.
