Übersicht
Generate video preview thumbnails for Plex, Emby and Jellyfin with GPU acceleration support. One FFmpeg pass writes the right format for each server (Plex BIF bundle, Emby sidecar BIF, Jellyfin trickplay tiles).
This template seeds a Plex connection below; add Emby/Jellyfin servers (any mix) from the web UI after first start.
Features:
- Web UI with setup wizard for easy configuration
- Plex OAuth authentication (no manual token needed)
- GPU acceleration (NVIDIA, Intel QuickSync, AMD)
- Background processing with job queue
- Real-time progress display
- Scheduled generation via cron expressions
- Browser notifications when jobs complete
The web interface is available at http://[IP]:8080 after starting the container.
A setup wizard will guide you through connecting to your Plex server.
IMPORTANT - NETWORKING:
If your Plex container uses a custom network (like br1 or macvlan), this container
must use the SAME network to communicate with Plex. Change the Network Type setting
to match your Plex container's network.
For Intel QuickSync, /dev/dri is passed through automatically (see GPU Device below).
For NVIDIA GPU support, you must:
- Install NVIDIA driver and nvidia-container-toolkit on Unraid
- Add --runtime=nvidia to Extra Parameters
- Or use the Nvidia-Driver and nvidia-container-toolkit plugins from Community Applications
- Add NVIDIA_DRIVER_CAPABILITIES=all to the environment variables below (the 'graphics' capability is required for Dolby Vision Profile 5 thumbnails; 'compute,video,utility' alone only covers NVDEC and nvidia-smi).

NVIDIA driver capabilities to inject into the container. Use 'all' (recommended) so the 'graphics' capability is included — this is required for Dolby Vision Profile 5 thumbnails (libplacebo Vulkan tone-mapping). 'compute,video,utility' alone only covers CUDA/NVDEC and will NOT give you DV5 support. Only applied if you also set --runtime=nvidia in Extra Parameters.
