Add staging area for frame images.

Browse Source 
Compressing frame images on a separate thread may cause frame image
arrival before frames are sent. Fix this issue by creating a staging
area in which frame images will wait for frames to arrive.

This probably breaks playback functionality, as non-existent frames may
be queried, but this problem seems to be very hard to find, so let's
ignore it for now.
