24/7 YouTube Multistream System Setup

I want to take a single live URL (the Makkah stream) and deliver it, round-the-clock, to 50 separate YouTube channels at once. My plan is to run everything on AWS, add a custom background music track that plays continuously behind the video, and manage every channel, key, and reconnection routine from one central dashboard.

Reliability is critical: the feed must auto-reconnect within seconds if the source drops, and downtime has to stay as low as technically possible. I am open to FFmpeg pipelines, NGINX-RTMP clusters, OBS instances, or SaaS relays such as Restream or Castr—whichever combination you can demonstrate will scale cleanly to fifty concurrent YouTube outputs and remain cost-efficient month after month.

Please respond only if you have already built or maintained large-scale multistreaming solutions. In your proposal include:

• A brief on similar projects you delivered (links or screenshots welcome)
• Your recommended architecture for this job
• Exact AWS instance specs, bandwidth needs, and any third-party services you’d layer in
• An estimate of the monthly running cost
• How many days you’ll need for initial setup and testing

If this first deployment runs smoothly, I will retain you for ongoing monitoring and additional channel expansions.
