- crates/media: probe (duration, rate/channels, size/fps; WMA/WMV recognised), audio decode to f32 PCM (MP3, AAC M4A/ADTS, ALAC, WAV, AIFF, CAF, FLAC, Vorbis via symphonia; Opus with our decoder in Ogg/WebM/MKV), video decode (MP4/MOV/WebM/MKV) with YUV->RGBA, poster frames, trim/fade/volume, Player mixer + per-voice clock (device-clocked or wall-clocked), VideoFeed. - Codec crates ported from FilmCraft: bitstream, h264, hevc, vp9, av1, isobmff, matroska, ogg, opus. - insert.audio/insert.video probe and store duration/size and a poster frame; unplayable media is embedded with a warning. New media.play/pause/toggle/stop/seek/info/posterFrame. - UI: MediaHost (cpal output injected by the desktop app), control bar under media, video frames on canvas and in the show; autoplay, click to play, loop, rewind, across slides, hide, full screen. - Tests with in-code WAV/AIFF and CC0 self-generated fixtures (make.sh, ATTRIBUTION.md rows).
