in your markdown, you can use refs to audio and video assets, same as an image:

![img tag](some-image.png)
![audio tag](some-audio.ogg)
![video tag](some-video.mp4)

then in your parser code:

var mdav = require('markdown-av')
var html = mdav('# presenting \n ![bideo](movie.mp4)')
document.body.innerHTML = html
