The openatstart.smil
presentation opened this HTML page automatically. That SMIL file uses the rn:contextWindow="openAtStart"
attribute in its <root-layout/>
tag to align the media playback pane flush left when the media browser pane is attached, leaving room for the related info pane, which appears a few seconds after the video begins to play. (The attribute has no discernible effect if the media browser pane is closed.)
If the SMIL file does not include rn:contextWindow="openAtStart"
, the media playback pane appears centered above the media browser pane, then moves to the left when the related info page displays, as shown in the sample closedatstart.smil
.
