Transcode state lives only in the process that started ffmpeg, so a pod restart drops every in-flight HLS stream with no way for a peer to pick it up. - add ITranscodeSessionStore plus the TranscodeSession and LiveStreamSession records - add RedisTranscodeSessionStore with TTL leases and an atomic Lua takeover script - add NullTranscodeSessionStore for single-instance deployments - pick the store from Jellyfin:TranscodeStore:RedisConnectionString at startup
