Device drivers/nodes should provide some time information about
a) when exactly given piece of data was captured,
   and time returned should be global to all capture devices
b) what latencies are assosiated with output devices.

Otherwise you will end up with annoying sync problems.

And second thing that comes to mind is that audio is more important
than video, so video stream should be synced to audio and not vice versa.
(You'd better drop some frames than produce annoying clicks).
