Caption window color
The Ooyala’s Flash desktop player supports the FCC 708 compliant closed caption UI controls. As long as a video has closed captions and is using the default Flash player, the updated closed captions feature will work.
FCC 708 compliance for closed captions is supported for both VoD and live streaming.
Customized Flash desktop players are not directly supported.

On a browser without any cached settings, when a player and asset are loaded with DFXP settings, all attributes as marked in the list above will be applied with default settings provided in the DFXP file. Once the end user modifies the CC settings through the UI interface, DFXP settings will be overridden for all settings and replaced with player defaults and user preferences. The Flash player defaults are described in the table below.

The viewer can set closed caption styling in two ways:
When viewers click on the CC button () in the UI, the video will continue to play. This means that you can turn closed captioning on and off without stopping the video. The video will only pause once you click CC button > Options.Note: A live video will never pause when you are managing closed captions (even when you click Options ).
To turn closed captions off, click CC button >Off.
Viewers can easily customize the look and feel of closed captions. They can see a preview of how the closed captions will look while setting the style.
