Describe The Problem:

Recording streams from my Dahua camera fail immediately with a TypeError: Cannot read properties of undefined (reading 'length'). Live view and snapshots still work, but recording never starts.

To Reproduce:

1. Add a Dahua camera to homebridge-camera-ffmpeg with recording: true and prebuffer: true.
2. Start Homebridge and trigger a recording stream.
3. Observe logs for .length error and stream closure.
