Transcoder Plugin

FFmpeg-based video transcoding — HLS, DASH, and MP4 output with MinIO storage. Pro plugin.

Requires: Basic license tier or higher. nself license set nself_pro_...

Install

nself license set nself_pro_xxxxx...
nself plugin install transcoder

What It Does

Transcodes video files using FFmpeg into adaptive streaming formats (HLS, DASH) and standard MP4. Manages an upload pipeline from MinIO (or direct upload), queues encoding jobs, and writes output back to MinIO. Integrates with the subtitle-manager plugin for subtitle embedding and the tokens plugin for content protection.

Dependencies

Requires MinIO (MINIO_ENABLED=true). Maps to media-processing in the plugin registry (port 3088, 9 tables).
