T26c Media: video

Scrubber shows what has loaded, what has played and its chapters, names
the time under the pointer, seeks by press and gpui's drag, and steps by
the slider's keys; over_media lights it for a dark layer. VideoPlayer
shows the host's frame in its shape with a caption and a control bar over
it: the scrubber, play, the time, speed, captions, picture in picture and
full screen, each only with its handler; the bar rests after a still
pointer while it plays, on one wake from the executor's timer. Keys:
Space and K, J and L, the arrows, C and F. VideoThumbnailStrip lays frames
along the length under a playhead with a trim whose handles drag and whose
ends I and O set. SubtitleEditor edits cues in place: times as mm:ss.mmm,
kept in order, a time that does not read kept out with the reason shown.

InlineEdit is a Tab stop with the ring; it hands focus back after Enter or
Escape and keeps its text on Enter's release. overlays::media_button is
shared by the lightbox and the player's bar.
