Package image is the media worker's image producer (libvips, CGO): the Image presets' private WebP files, the Zip presets, the public presets' owned generations, editor views, and the kinds' default public images.

Package video runs an item's video-family presets with ffmpeg: HLS (a byte-range fMP4 ladder with the source's audio and text tracks and a seek sprite), MP4 (a muxed H.264 file at one rung), Audio (an HLS track and an M4A) and Subtitles (clean WebVTT), and grabs the frames of uploads that declare Upload.Frames.

Package worker is the media worker: the one process that places uploads and runs every producer, from the host's worker River schema (Config.Schema) in its database: staged uploads hashed and placed at their blobs (media.Manifests.Place), images, zips, public presets and editor views (media/image, libvips), and HLS, MP4, subtitles and frames (media/video, ffmpeg).

Package workqueue is the host's side of the media worker (media/worker): the River schema it drains in the host database, insert-only enqueueing and cancelling of its jobs, and processing progress for the read API.
