Disabling the play/pause button on the Spark VideoPlayer control in Flex 4

The following example shows how you can disable/enable the play/pause button on the Spark VideoPlayer control in Flex 4 by setting the enabled property on the VideoPlayer control’s playPauseButton skin part.

The following example(s) require Flash Player 10 and the Adobe Flex 4 SDK. To download the Adobe Flash Builder 4 trial, see www.adobe.com/products/flex/. To download the latest nightly build of the Flex 4 SDK, see opensource.adobe.com/wiki/display/flexsdk/Download+Flex+4.

This entry is based on a beta version of the Flex 4 SDK and therefore is very likely to change as development of the Flex SDK continues. The API can (and will) change causing examples to possibly not compile in newer versions of the Flex 4 SDK.

  1. If I visit a site showing a flash video with a disabled play button, how can I stop the video without closing the site?

    1. @scott,

      You probably wouldn’t be able to, unless the developer added another method (custom context menu, for example) to play/pause the video. I wasn’t imaging building a YouTube or Hulu type site where users wouldn’t be able to pause a video, I was thinking more of how Hulu and other sites sometimes disable the ability to pause an advertisement or something.
