Just read the docs anyway including docs/design/*.txt. Autoplugging is
not magic, just use signals to get notified about new pads, check the

by rank and ignore those with rank=0.
It might be better in the long run to figure whats the issue with
playbin2 and vaapi/vdpau and make sure we can fix it in 0.10 or at least
