SetHWZDefault(default As String) As Void

Sets the default HWZ mode for HTML video. Normally, HWZ must be enabled in each <video> tag, but passing "on" to this string enables HWZ for all <video> elements. This method can also accept a semicolon-separated list of HWZ parameters:

• on/off: Enables or disables HWZ mode.
• z-index: Sets the default z-ordering for <video> elements. A positive integer places the video in front of all graphics; a negative integer places the video behind all graphics; and a zero value disables HWZ mode completely. You can customize the z-ordering of individual video elements with respect to each other by inserting the "z-index" parameter into the <video> tag.
• transform: Sets the default rotation for <video> elements. HWZ mode must be enabled for transforms to work.
  • identity: No transformation (default behavior)
  • rot90: 90 degree clockwise rotation
  • rot180: 180 degree rotation
  • rot270: 270 degree clockwise rotation
  • mirror: Horizontal mirror transformation
  • mirror_rot90: Mirrored 90 degree clockwise rotation
  • mirror_rot180: Mirrored 180 degree clockwise rotation
  • mirror_rot270: Mirrored 270 degree clockwise rotation
• fade: Sets the fading behavior for <video> elements.
  • auto: Videos transition without fade effects. This is the default behavior.
  • always : When a video ends, the video window will go black. The new video will then fade in.
• luma-key/cr-key/cb-key: Enables luma and/or chroma keying for <video> elements. HWZ mode must be enabled for luma/chroma keying to work.
