Displays a video. According to the HTML5 standard, the supported video formats are mp4, webm, and ogv, but actual support depends on the Web browser being used to access the pages. It allows dynamic control of position, visibility, play/pause and mode.


  • id: the object's ID, used by UISets
  • src: path to the video file, without the extension. The browser will automatically select a supported format between the available versions (MP4, OGG and WEBM)
  • position: the object's position. Use the pixels or rows and columns coordinates format
  • size:the video's width and height
  • mode: selects the playback mode, see the mode attribute below
Video files are searched inside the www/<project's name>/img directory first, then inside the www/img directory.
The extension must not be specified. The browser will search for MP4, OGG and WEBM extension, depending on which format is supported


(video!id <src>; <pos>; <width>; <height>; <mode>)


(video!myvideo video; r5c2; 100; 100; stop)
