#+TITLE: QA 16 — Inline Video (macOS Metal only)
#+TODO: TODO | PASS FAIL SKIP

* Platform note
  This test applies only to macOS with the Metal backend.
  Mark all items as SKIP on Linux / GL.

* How to run
  : emacs --no-init-file -l qa/16-video/test.el
  : (provide a .mp4 path when prompted)

  Vanilla baseline: N/A (video is a GPU-only feature).

* Checklist

** TODO 16.1 SKIP [Linux/GL] Placeholder appears after gpu-video-insert
   After inserting a video, a blank placeholder (space) must appear
   at the insertion point.
   Failure: nothing is inserted, or an error is thrown.

** TODO 16.2 SKIP [Linux/GL] Video plays at the placeholder position
   When playback starts, the video must appear over the placeholder,
   not at a fixed screen position.
   Failure: video appears at the top-left of the frame, or not at all.

** TODO 16.3 SKIP [Linux/GL] Video follows scroll
   Scroll the buffer while the video is playing. The video must move
   with the text.
   Failure: video stays fixed at its initial screen position while the
   text scrolls underneath.

** TODO 16.4 SKIP [Linux/GL] Video clipped to window interior
   The video must not bleed over the mode-line or over other windows.
   Failure: video pixels are visible over the mode-line or in an
   adjacent split window.

** TODO 16.5 SKIP [Linux/GL] gpu-video-stop removes playback
   After stopping, the placeholder must remain but the video overlay
   must disappear.
   Failure: video frame remains frozen on screen after stop.

** TODO 16.6 SKIP [Linux/GL] Cadence — stable 30fps
   During playback, the frame rate must be stable (~33ms per frame).
   Check with: =(setq gpu-video-debug t)= and observe the echo area.
   Failure: visible stutter (frame drops), or echo area shows >50ms gaps.

** TODO 16.7 SKIP [Linux/GL] No interference with text rendering
   During video playback, typing text or scrolling must not corrupt
   the video overlay or the text in the buffer.
   Failure: video pixels bleed into the text area, or text rendering
   is corrupted while the video is playing.
