How to "put the video in the corner of slides"

[bremner]

The commit message is tantalizing, but I didn't make it work yet. Based on guesswork, I tried

<?xml version="1.0" encoding="UTF-8"?>
<movie>
  <video src="1-1.mkv" slide="page000.png" />
  <video src="1-2.mkv" slide="page001.png" />
  <video src="1-3.mkv" />
</movie>

This produces the attached input for melt. autocut.out.txt

This has the audiotrack over the relevant slides, but no picture from the video files. For reference my melt command looks like

	melt -profile hdv_1080_30p -consumer avformat:out.avi in.xml
