Fixing Frigate’s RTSP Issues on Kubernetes

If you’ve tried deploying Frigate NVR on Kubernetes — in this case on Talos Linux — you may have run into a situation where cameras fail to connect and Frigate’s API stops working correctly. The root cause comes down to how OpenCV handles RTSP streams by default, and the fix is a single environment variable.

What’s Going On

Frigate’s FastAPI layer uses OpenCV under the hood for certain frame-level operations. By default, OpenCV probes RTSP streams over UDP. Under most environments this works fine, but in Kubernetes — especially with CNI plugins like Flannel — UDP-based RTSP handling tends to break silently, causing the API to malfunction.

Proxmox homelab with Talos and TrueNAS

I recently rebuilt my homelab around Proxmox as the hypervisor and Talos Linux for running applications. This is a short overview of how it is put together.

Virtualisation

A single Proxmox host runs the whole setup as virtual machines:

TrueNAS runs as a VM and handles storage. Disks are passed through to it so that ZFS manages them directly, and it exposes that storage back to the other VMs over NFS and iSCSI.
Talos Linux provides a minimal, immutable, API-driven Kubernetes OS. All of my self-hosted applications run here rather than directly on the host.

Keeping everything as VMs on Proxmox makes it easy to snapshot, back up and rebuild individual pieces without touching the rest.
