Insert video by using the standard HTML5 markup. Videos are always stretched to the size of the column. Safari and Chrome support .mp4 files, but Firefox does not. You have to convert the video to the “ogg-format” to get the video working in Firefox. There are a lot of video conversion tools out there. MiroVideo Converter for example is free and simple. For detailed information about video see http://diveintohtml5.info/video.html.Autoplay is now also supported and configured via the book.json-file.
The following markup includes both filetypes. The browser decides which one to use:
<video controls preload> <source src="images/myvideo.mp4"> <source src="images/myvideo.ogv“ type="video/ogg"> </video>
