Video and audio playback on iPhone Duo, Apple's foldable. Use when an app plays video or audio and must keep playing through fold, unfold and rotation, when you build a tabletop player (video above the fold, the same controls below) or a book-pose player, an up next queue, Picture in Picture, Now Playing or background audio. Covers one AVPlayer owned above the layout switch (VideoPlayer, AVPlayerViewController, AVPlayerLayer), ArrangementView with .overlay and overlayArrangementZIndex for up…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# duo-media People open, close and fold iPhone Duo while something plays. The video must not stop, restart or flash, and the controls must land where hands can reach them in every pose. This skill covers players, the tabletop layout, "up next", Picture in Picture, Now Playing and the audio session. Load neighbours when the task needs them: `duo-continuity` (where state lives, for every kind of state), `duo-postures` (every pose, and the tabletop recipe with `FoldRegionsLayout`), `duo-layout` (`ArrangementView` in depth), `duo-scenes` (Split View and windows), `duo-camera` (capture). "Tabletop" and "book" are Duology's words for what Apple describes as the phone seated on a table like a laptop, and partly folded like a book. Neither is an API. Labels: *measured* means we ran it on the iPhone Duo simulator (iOS 27.1); *derived* means reasoning from Apple's words or our measurements; *unverified* means we could not check it. Full source list: [reference/sources.md](https://github.com/Kimeur/duology/blob/main/reference/sources.md). ## Rules 1. One `AVPlayer` per window, in a model owned above every layout switch. Views only show it. …

How to install
mdr add kimeur/duology/duo-media@sha256:b77a836020fa3b76The line at the top of this page pins the label git:20261020.622656d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
