af714091aa cea608mux: don't consume input buffers too early 
CCBuffer has no notion of time, we need to push caption pairs in
it when it is ready for consumption and no earlier.

Also perform comparisons with our output running time, not the raw
output PTS.

84d6323610 closedcaption: implement cea608muxer element 
Wrapper aggregator around the CCBuffer internal utility, this
version only supports aggregating CC1 and CC3 608 streams together into
the s334-1a format.

The element exposes CC1 and CC3 request pads.
