#Color and container consumer

Run this separate-package example from the repository root with the pinned MoonBit toolchain:

moon run examples/color_video --target native
moon run examples/color_video --target js
moon run examples/color_video --target wasm-gc

The example uses retained fixtures and performs no file or network I/O. It demonstrates ICC relative conversion with explicit black-point compensation, native HDR tone mapping, fractional AVIF resampling, complete and incremental IVF/MP4/WebM decoding, timestamp seeking and explicit MP4 edit-list mapping.

Incremental input uses 37-byte chunks and an 8 KiB compressed-input budget. feed copies pending input; each returned packet/frame owns its pixel or payload arrays. Consume batches as they arrive. finish declares actual EOF, which is distinct from an empty feed. A tail-moov MP4 first discovers its index, returns ReplayRequired, then needs replay() and the identical source resent from byte zero. The peak counter covers both passes since reset. The host supplies any real file reader and rewind operation.

Seeking uses raw media ticks and returns a checked at-or-after result. The presentation timeline is an explicit separate operation; an empty MP4 edit maps to Empty, never a fabricated AV1 picture. The complete API contracts are in container streaming, timeline and seeking and ICC input profiles.
