Videos

Videos can be referenced in a DITA topic by using the <object> element:

<object data="path/to/video.mp4" outputclass="video"/>

How to Reference a Video Using a Key

Videos can also be referenced in DITA topics by using a key.

The key must be defined in the DITA map like this:

<keydef keys="video" href="path/to/video.mp4" format="mp4"/>

The key is referenced in the topic with the @datakeyref attribute within the <object> element:

<object datakeyref="video" outputclass="video" width="480" height="270"/>

How to Change Video Size

It is possible to set the size for your videos directly from a custom CSS stylesheet:

.video {
  width: 480px;
  height: 270px;
}

How to Change the Videos Cover

By default, a placeholder is displayed in place of the video. When clicked, this placeholder launches the video. A popup is presented in Acrobat Reader to enable the Multimedia content (the document must be trusted for the video to launch).

It is possible to change this placeholder with a custom one by using the -oxy-video-cover property:

.video {
  -oxy-video-cover: url("files/cover.png");
}

How to Center Videos

It is possible to center the videos by centering their containers like this:

.video-container {
  text-align: center;
}
