Using the <video> tag

Attributes(what's this?)

• src (required): The location of the video file. It must be a URL value. If the video is stored alongside the module, the file name itself can be used (e.g. "clip.mp3").

  Note:

  Starting with version 0.6, the CNXML language does not permit URLs that contain ampersand (&) characters (i.e., http://cnx.org/example?i=1&p=2). Check all object src URLs and replace any ampersands with the entity reference "&amp;". More information can be found on the W3C's page.
• mime-type (required): The MIME type of the video. This requried value tells each visitor's browser what sort of information is contained in the video file. A list of common Internet media MIME types can be found here.
• for (optional): Specifies whether this object should be displayed in the online or PDF version of the content, or be used as the default media object. If there is no default media object present, then the <media> element will only be displayed for the version(s) specified.
  Possible values:
  • default - This element is used for both PDF and online versions unless another, version-specific element is present (default).
  • pdf - This element is used only for the PDF version of the content.
  • online - This element is used only for the online version of the content.
• standby (optional): A message to display while the video data is loading.
• autoplay (optional): Toggles the video file on or off autoplay mode.
  Possible values:
  • true - Plays the video file automatically.
  • false - Does not play the video file automatically.
• loop (optional): Toggles video file looping.
  Possible values:
  • true - Loops the video.
  • false - Does not loop the video (default).
• controller (optional): Toggles a timeline controller for the video file.
  Possible values:
  • true - Displays a timeline controller.
  • false - Does not display a timeline controller.
• volume (optional): Sets the volume of the video file. Default is any integer from 1 to 100 (default is "50").
• height (optional): The height of the video in pixels.
• width (optional): The width of the video in pixels.
• longdesc (optional): The URL of a file containing a long description of the video. Not all readers will be able to see your included media in their browser, either due to blindness, low-vision, or an environment that doesn't support the media. Some videos are too complex to describe fully in a few words using the "alt" attribute, however. For videos that are important for understanding the material, use "longdesc" to point to a Web file that contains a full explanation of the video.
• id (optional): A unique identifier, whose value must begin with a letter and contain only letters, numbers, hyphens, underscores, colons, and/or periods (no spaces).
