Interface: ContainerFormatEntry

Defined in: packages/media/src/container-formats.ts:17

The container-format registry — export's counterpart to the timeline's element-type registry. A container format is an output vocabulary entry: its id (also the default file extension), a UI label, and a factory for the Mediabunny OutputFormat that muxes it.

The built-in formats (mp4, webm, mkv) register through this exact API, so community formats are first-class: they show up in listContainerFormats (which the export dialog renders), pass WebCodecs support probing via getExportSupport, and export via exportProject({ format: id }).

Register custom formats at module load, before the export UI mounts.
