(Notes from internal brainstorm: may change as work is carried out):

#13 Test video encoder passing timing information through correctly

Encoder should pass through newsegment event, should remember segment
configuration, should handle and pass through segment updates. Encoder
should do correct clipping at segment boundaries (if
timestamp+duration > segment.end either drop buffer, or if timestamp <
segment.end clip duration so that timestamp+duration = segment.end).
Encoder should pass timestamps through correctly (ie. output
timestamps should match input timestamps if adjusted for
display/coding order re-ordering that may happen), even if there are
jumps or there is jitter.
