CC for Flash

CC for Flash | ccPlayer | ccMP3Player | MAGpie

ActionScript 3 versions of CC for Flash and the ccPlayer are now available. Read about the new features.

NCAM has developed a Flash component that can be used to display captions of Flash video and audio content. These captions are stored in external files formatted in the W3C's DFXP format which can be created with MAGpie, NCAM's free captioning application. CC for Flash can also display captions saved in Apple's QTtext format. QTtext files can be created by professional caption authoring tools, with MAGpie or with CaptionKeeper, NCAM's line-21 caption-conversion tool.

Depending on which version of CC for Flash is used, authors can link to any of the following objects:

  • FLVPlayback component
  • MediaDisplay component
  • Netstream object
  • Sound object
  • Movie clip or SWF timeline

The CC for Flash component is customizable and allows authors to set defaults, such as the width and height of the caption area, the caption area's background and text colors, the opacity of the background (for placing captions over the video), and the font family and font size of the captions themselves.

Other features include:

  • access to captions stored internally in the Flash movie or embedded in the FLV video file;
  • caption search, returning the timecodes where text strings occur;
  • roll-up caption display;
  • switching between multiple languages of captions that have been stored in the same DFXP file;
  • ability to provide parsed caption data to other objects in the Flash movie;
  • manual operation where a timecode is presented and the corresponding caption is displayed (AS3 version only).

For those who are not handy with Flash programming, NCAM has created two flexible players which ease the process of providing captioned Flash video and MP3 audio files: ccPlayer, incorporating the CC for Flash component, allows you to embed a FLV player on your Web page; ccMP3Player, which also incorporates the CC for Flash component, plays back MP3 files in a Web page with corresponding caption files. Both players are accessible to screen readers and can be operated solely from the keyboard.

Support for the creation of CC for Flash was provided by the NEC Foundation of America and Yahoo!
