Building an AI Avatar Live Streaming System That Runs Unattended

When building an AI avatar live streaming system that runs unattended, the development focus shifts from a typical application. If the system crashes during unmonitored hours, no one is there to fix it. This means that instead of just "working well," the key to quality is making sure the system "understands when it breaks and can recover on its own."

This article summarizes the pitfalls encountered while getting such a system to run continuously on Twitch, broken down into three layers:

Authentication Layer: OAuth for EventSub and metadata manipulation. The constraints of manual human steps and tokens that aren’t immutable.

Transmission Layer: Even when ffmpeg is sending video, the channel doesn’t go live. Twitch silently accepts invalid keys.
