Transcoding intermittent issue

You'd probably have more luck searching through your system logs for the host instead of Jellyfin's ffmpeg logs. Jellyfin would likely only say that permission to access the GPU was denied or that there is no valid Nvidia GPU available. Not necessarily why.

Does Nvidia have its own service or something? It sounds like a race condition where something Nvidia related isn't available before your LXC starts.
