Keyframe info

When I used VideoDisplay as base for my player the metadata of the the mp4 videos I play used to contain a neat array of available key frames. Do I have access to the info in the OSMF player? I rummaged in the debugger for a while, but the metadata object I can get at, doesn't seem to hold anything useful for me.
Thanks.
p.s.: Wish one could search just a specific subforum,
